Abstract
Ritonavir, an excellent inhibitor of CYP3A4, has recently been combined with nirmatrelvir to form Paxlovid for the treatment of severe acute respiratory syndrome coronavirus 2 infections. The root of Scutellaria baicalensis Georgi (S. baicalensis), a traditional Chinese medicinal (TCM) herb commonly used to treat heat/inflammation in the lung and digestive tracts, which are major organs targeted by viral infections, contains flavones that can influence the CYP3A metabolism pathway. To investigate the ability of ritonavir to cross the bloodbrain barrier (BBB) and its potential herb-drug interactions with an equivalent TCM clinical dose of S. baicalensis, multisite microdialysis coupled with an LCMS/MS system was developed using rat model. Pretreatment with S. baicalensis extract for 5 days, which contains less flavones than those used in previous studies, had a significant influence on ritonavir, resulting in a 2-fold increase in the total concentration of flavones in the blood and brain. Treatment also boosted the maximum blood concentration of flavones by 1.5-fold and the maximum brain concentration of flavones by 2-fold, all the while exerting no noticeable influence on the transfer ratio across the bloodbrain barrier. These experimental results demonstrated that the use of a typical traditional Chinese medicinal dose of S. baicalensis is sufficient to influence the metabolic pathway and synergistically increase the concentration of ritonavir in rats.

Abstract
Hepatitis D virus (HDV), which co-infects or superinfects patients with hepatitis B virus, is estimated to affect 74 million people worldwide. Chronic hepatitis D is the most severe form of viral hepatitis and can result in liver cirrhosis, liver failure, and hepatocellular carcinoma (HCC). Currently, there are no efficient HDV-specific drugs. Therefore, there is an urgent need for novel HDV therapies that can achieve a functional cure or even eliminate the viral infection. In the HDV life cycle, agents targeting the entry step of HDV infection preemptively reduce the intrahepatic viral RNA. Human sodium taurocholate co-transporting polypeptide (hNTCP), a transporter of bile acids on the plasma membrane of hepatocytes, is an essential entry receptor of HDV and is a promising molecular target against HDV infection. Here, we investigated the effect of ergosterol peroxide (EP) on HDV infection in vitro and in vivo. EP inhibited HDV infection of hNTCP-expressing dHuS-E/2 hepatocytes by interrupting the early fusion/endocytosis step of HDV entry. Furthermore, molecular modeling suggested that EP hinders LHBsAg binding to hNTCP by blocking access to S267 and V263. In addition, we generated hNTCP-expressing transgenic (Tg) C57BL/6 mice using the Cre/loxP system for in vivo study. EP reduced the liver HDV RNA level of HDV-challenged hNTCP-Cre Tg mice. Intriguingly, EP downregulated the mRNA level of liver IFN-γ. We demonstrate that EP is a bona fide HDV entry inhibitor that acts on hNTCP and has the potential for use in HDV therapies.

Abstract
Sepsis results from uncontrolled inflammation, characterized by cytokine storm and immunoparalysis. To assess whether galgravin, a natural lignan isolated from Piper kadsura, can be used to treat sepsis, models of bacterial lipopolysaccharide (LPS)-activated macrophages and LPS-induced endotoxemia mice were used. Galgravin suppressed NF-κB activation in LPS-activated RAW 264.7 macrophages without causing significant cytotoxicity, in which proinflammatory molecules like TNF-α, IL-6, iNOS, and COX-2 were downregulated. In addition, the expression of TNF-α and IL-6 was also suppressed by galgravin in LPS-activated murine bone marrow-derived macrophages. Moreover, galgravin significantly downregulated the mRNA expression of TNF-α, IL-6, and iNOS in the lungs and decreased TNF-α and IL-6 in the serum and IL-6 in the bronchoalveolar lavage fluid of LPS-challenged mice. The COX-2 expression in tissues, including the lung, liver, and kidney, as well as the lung alveolar hemorrhage, was also reduced by galgravin. The present study reveals the anti-inflammatory effects of galgravin in mouse models and implies its potential application in inflammation diseases.

Abstract
BACKGROUND Remdesivir was the first prodrug approved to treat coronavirus disease 2019 (COVID-19) and has the potential to be used during pregnancy. However, it is not known whether remdesivir and its main metabolite, GS-441524 have the potential to cross the blood-placental barrier. We hypothesize that remdesivir and predominant metabolite GS-441524may cross the blood-placental barrier to reach the embryo tissues. METHODS To test this hypothesis, ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) coupled with multisite microdialysis was used to monitor the levels of remdesivir and the nucleoside analogue GS-441524 in the maternal blood, fetus, placenta, and amniotic fluid of pregnant Sprague-Dawley rats. The transplacental transfer was evaluated using the pharmacokinetic parameters of AUC and mother-to-fetus transfer ratio (AUCfetus/AUCmother). FINDINGS Our in-vivo results show that remdesivir is rapidly biotransformed into GS-441524 in the maternal blood, which then readily crossed the placenta with a mother-to-fetus transfer ratio of 0.51 ± 0.18. The Cmax and AUClast values of GS-441524 followed the order: maternal blood > amniotic fluid > fetus > placenta in rats. INTERPRETATION While remdesivir does not directly cross into the fetus, however, its main metabolite, GS-441524 readily crosses the placenta and can reside there for at least 4 hours as shown in the pregnant Sprague-Dawley rat model. These findings suggest that careful consideration should be taken for the use of remdesivir in the treatment of COVID-19 in pregnancy. FUNDING Ministry of Science and Technology of Taiwan.

Abstract
COVID-19 is a global epidemic. Developing adjuvant therapies which could prevent the virus from binding to cells may impair viral infection. This study produces a traditional Chinese medicine formula, Jing Guan Fang (JGF), based on ancient medical texts, and examines the efficacy and the mechanism by which JGF prevents viral infections. JGF reduces COVID-19 like symptoms. Functional studies show that JGF inhibits the formation of syncytium and reduces the formation of viral plaque. JGF is not toxic in vitro and in vivo. Mechanistically, JGF induces lysosomal-dependent ACE2 degradation and suppresses mRNA and the protein levels of TMPRSS2 in human lung WI-38 and MRC-5 cells. Mice that inhale JGF exhibit reduced ACE2 and TMPRSS2 protein levels in lung tissues. Together, these findings suggest that JGF may improve the COVID-19 like symptoms and inhibit viral infection. Moreover, JGF may be applicable as an adjuvant preventive strategy against SARS-CoV-2 infection in addition to the use of vaccines.

Abstract
Chloranthus oldhamii Solms (CO) is a folk medicine for treating infection and arthritis pain but its pharmacological activity and bioactive compounds remain mostly uncharacterized. In this study, the anti-inflammatory compounds of C. oldhamii were identified using an LPS-stimulated, NF-κB-responsive RAW 264.7 macrophage reporter line. Three diterpenoid compounds, 3α-hydroxy-ent-abieta-8,11,13-triene (CO-9), 3α, 7β-dihydroxy-ent-abieta-8,11,13-triene (CO-10), and decandrin B (CO-15) were found to inhibit NF-κB activity at nontoxic concentrations. Moreover, CO-9 and CO-10 suppressed the expression of IL-6 and TNF-α in LPS-stimulated RAW 264.7 cells. The inhibitory effect of CO-9 on TNF-α and IL-6 expression was further demonstrated using LPS-treated bone marrow-derived macrophages. Furthermore, CO-9, CO-10, and CO-15 suppressed LPS-triggered COX-2 expression and downstream PGE2 production in RAW 264.7 cells. CO-9 and CO-10 also reduced LPS-triggered iNOS expression and nitrogen oxide production in RAW 264.7 cells. The anti-inflammatory mechanism of the most effective compound, CO-9, was further investigated. CO-9 attenuated LPS-induced NF-κB activation by reducing the phosphorylation of IKKα/β (Ser176/180), IκBα (Ser32), and p65 (Ser534). Conversely, CO-9 did not affect the LPS-induced activation of MAPK signaling pathways. In summary, this study revealed new anti-inflammatory diterpenoid compounds from C. oldhamii and demonstrated that the IKK-mediated NK-κB pathway is the major target of these compounds.

Abstract
BACKGROUND The flower of Dendranthema morifolium Ramat Tzvel has been widely used as a nutritional health supplement worldwide. However, most of the studies have focused on the flower and the rest of the plant was neglected. Our hypothesis is that similar flavonoids may be present at different parts of D. morifolium, and the flavonoids may undergo a similar biotransformation pathway within the body. To investigate this hypothesis, an in vivo pharmacokinetic experimental model was developed to explore the comparative biotransformation of luteolin and apigenin after administration of D. morifolium extracts (10 g kg-1 , p.o.) in freely moving rats. Because luteolin and apigenin mainly underwent phase II metabolism, the metabolic enzymes of β-glucuronidase/sulfatase or β-glucuronidase were used to hydrolyze the plasma sample, depending on the biotransformation pathway involved. RESULTS The results revealed that luteolin and apigenin mainly went through glucuronide and sulfate conjugations, respectively, in both the extract of flowers and the stem-and-leaf group. In addition, the area under the concentration curve (AUClast ) of luteolin glucuronides and sulfates in the group administered the stem-and-leaf extract was approximately 4.6 times higher than that of the flower extract group. The dominant products of biotransformation for apigenin were sulfates. CONCLUSION These findings support our hypothesis that not only the flower parts of D. morifolium, but also the stem-and-leaf parts contain rich flavones, including glycosides and aglycone, and they undergo similar biotransformation pathways. © 2021 Society of Chemical Industry.

Abstract
INTRODUCTION Oral disease is a widespread problem in Nepal. However, up-to-date information on oral health is limited and oral health initiatives may be shaped by assumptions about insufficient oral health knowledge. Furthermore, the influence of socio-demographic factors on oral health in Nepal remains unclear. This study aims to explore the relationship between demographic background and oral health knowledge, attitudes and behaviors in rural Nepal. METHODS Secondary analysis of data from a community-based survey on oral health knowledge, beliefs, practices, and access to care among residents ages 12 and above across 4 rural villages in Nepal's Kaski District (Total number = 3,243). Chi-square tests were performed to examine associations among oral health knowledge, attitudes and behaviors and demographic characteristics. RESULTS Participants reported a baseline knowledge of oral health; 92.4% knew about the recommended tooth-brushing regimen. Participants with higher education and younger age demonstrated better oral health knowledge. Misconceptions about dental treatment causing blindness (23.1%), deafness (11.6%), and mental health problems (14.9%) were reported across all groups. CONCLUSION Numerous factors besides knowledge likely determine individual oral health behavior. Future interventions should consider community-based outreach programs and dental care delivery through community Health Posts to build trust in dental care, build on existing knowledge and community experiences, and improve access to preventative care. Up-to-date understanding of oral health knowledge and practices and sociocultural influences on oral health behavior will better focus interventions and policy decisions.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ambroxol elevates glucocerebrosidase (GCase) activity and reduces nigrostriatal alpha-synuclein burden to better ameliorate motor function in Parkinson's disease (PD). Polygala tenuifolia is a potential alternative botanical medicine for the treatment of many nonmotor symptoms of PD commonly used in Taiwanese patients. Co-administration of these two medicines pose potential herb-drug interaction. AIM OF THE STUDY Our hypothesis is that ambroxol and P. tenuifolia may potentially possess herbal drug synergetic effects in the blood and brain. MATERIALS AND METHODS To investigate this hypothesis, a multiple microdialysis system coupled with validated ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for rat blood and brain samples. Experimental rats were divided into three groups: low-dose and high-dose ambroxol alone (10 mg/kg, i.v. and 30 mg/kg, i.v., respectively) and ambroxol (10 mg/kg, i.v.) pretreated with P. tenuifolia extract (1 g/kg, p.o. for 5 consecutive days). RESULTS Ambroxol easily penetrated into the brain and reached a maximum concentration in the striatum at approximately 60 min after low- and high-dose treatment. The area under the concentration curve (AUC) ratio increased proportionally at the doses of 10 and 30 mg/kg, which suggested a linear pharmacokinetic manner of ambroxol. The brain penetration of ambroxol was approximately 30-34%, which was defined as the ambroxol AUC blood-to-brain distribution ratio (AUCbrain/AUCblood). The P. tenuifolia extract did not significantly alter the pharmacokinetics of ambroxol in the blood and brain of rats. CONCLUSION The present study suggests that it is safety without pharmacokinetic interactions for this dosing regimen to use P. tenuifolia extract and ambroxol together.

Abstract
Objective: To explore the efficacy and safety of the covered airway stent loaded with (125)I seeds for the treatment of tracheal adenoid cystic carcinoma (TACC). Methods: We retrospectively reviewed the clinical data from 8 patients with TACC who had received placement of the covered stent loaded with (125)I seeds between December 2014 and July 2017 in the endoscopic center of the Second Affiliated Hospital of Xiamen Medical College. We compared the difference in the dyspnea index, the diameter of the airway lumen, and the lesion surrounding the airway wall before and after treatment. The complications were also recorded during follow-up. Results: Eight patients underwent successful placement of a total of 11 radioactive stents (2 straight-type stents, 2 L-shape stents, and 7 Y-shape stents, all loaded a total of 243 radioactive particles). Displacement of stents took place within 2 weeks in 2 patients, who were managed with re-stenting and fixation. No further displacement occurred during follow-up. The median time to stent removal was 2.9(interquartile range: 2.3,3.0) months. After stent placement, the dyspnea index was significantly decreased compared with pre-treatment level (mean: 0.1 vs. 3.4, t=8.881, P<0.001). Bronchoscopic re-assessment showed that the residual tumor within the airway was detected in only one patient and that the tumor completely disappeared in the remaining 7 patients. Treatment with stents loaded with radioactive particles yielded smooth and pale airway mucosa with formation of partial scar formation. Chest computed tomography re-assessment demonstrated significantly larger luminal diameter than that before treatment (mean: 13.1 mm vs. 3.3 mm, t=-7.839, P<0.001). The airway wall thickness was notably reduced after treatment (mean: 4.3 mm vs. 14.4 mm, t=7.620, P<0.001). The lesions surrounding the airway wall completely disappeared in 7 patients and decreased for more than 50% in a single patient. The median duration of follow-up was 28.0(interquartile range: 24.8,31.5) months. Recurrence of tumor was documented in a single case within 2 years. Six patients did not experience recurrence within the 2-year follow-up period. No death or severe complications were recorded during follow-up. Conclusion: The (125)I radioactive stent is effective for dilating the stenotic airway and ameliorating the symptoms, and thus might be an effective and safe method for the treatment of TACC. Further studies that explore the efficacy of stents loaded with (125)I particles are needed.

Abstract
Three new labdane-type diterpenoids, 6α-O-isovalerylnidorellol (1), (12S)-blumdane (2), and (12R)-epiblumdane (3), and three new bisnorditerpenoids, 6α-O-(3-methyl-2-butenoyl)sterebin A (5), 6α-O-angeloylsterebin A (6), and 6α-O-isovalerylsterebin A (7), plus 17 known compounds were isolated from Blumea aromatica. Their structures of the new compounds were proposed by detailed spectroscopic analysis. The absolute configuration at C-12 of blumdane (2) was determined by the modified Mosher's method. The anti-inflammatory and anti-immunosuppressive effects of these isolated compounds were assessed. Compounds 9, 16, and 23 (at 40 μM) showed a slight suppression of TNF-α production, but no or little effect on the expression of PD-L1 in granulocytic myeloid-derived suppressor cells was observed for all test compounds.

Abstract
BACKGROUND Boschniakia rossica is a well-known traditional Chinese medicine for tonifying kidney and improving impotence. Boschnaloside is the major iridoid glycoside in this herb but therapeutic benefits for diabetes remained to be evaluated. HYPOTHESIS/PURPOSE The current investigation aims to study the antidiabetic effect and the underlying pharmacological mechanisms. STUDY DESIGN AND METHODS Receptor binding, cAMP production, Ins secretion, glucagon-like peptide 1 (GLP-1) secretion, and dipeptidyl peptidase-4 activity assays were performed. Therapeutic benefits of orally administrated boschnaloside (150 and 300 mg/kg/day) were evaluated using severely 12-week old female diabetic db/db mice (Hemoglobin A1c >10%). RESULTS Oral treatment of boschnaloside for 4 weeks improved diabetic symptoms including fasting blood sugar, hemoglobin A1c, glucose intolerance, and Homeostatic Model Assessment of Ins Resistance, accompanied by circulating GLP-1active and adiponectin levels. In addition, bochnaloside treatment improved islet/β cell function associated with an alteration of the pancreatic and duodenal homeobox 1 level. It was shown that boschnaloside interacted with the extracellular domain of GLP-1 receptor and enhanced glucose stimulated Ins secretion. Boschnaloside also augmented the insulinotropic effect of GLP-1. Finally, the presence of boschnaloside caused a reduction of dipeptidyl peptidase-4 activity while enhanced GLP-1 secretion from STC-1 cells. CONCLUSION It appears that bochnaloside at oral dosage greater than 150 mg/kg/day exerts antidiabetic effects in vivo through modulating the action of GLP-1.

Abstract
Background Dietary fat has been suggested to be the cause of various health issues. Obesity, hypertension, cardiovascular disease, diabetes, dyslipidemia, and kidney disease are known to be associated with a high-fat diet (HFD). Obesity and associated conditions, such as type 2 diabetes mellitus and nonalcoholic fatty liver disease (NAFLD), are currently a worldwide health problem. Few prospective pharmaceutical therapies that directly target NAFLD are available at present. A Traditional Chinese Medicine, ginseng-plus-Bai-Hu-Tang (GBHT), is widely used by diabetic patients to control glucose level or thirst. However, whether it has therapeutic effects on fat-induced hepatic steatosis and metabolic syndrome remains unclear. Methods This study was conducted to examine the therapeutic effect of GBHT on fat-induced obesity, hepatic steatosis, and insulin resistance in mice. Results GBHT protected mice against HFD-induced body weight gain, hyperlipidemia, and hyperglycemia compared with mice that were not treated. GBHT inhibited the expansion of adipose tissue and adipocyte hypertrophy. No ectopic fat deposition was found in the livers of HFD mice treated with GBHT. In addition, glucose intolerance and insulin sensitivity in HFD mice was also improved by GBHT. Conclusion GBHT prevents changes in lipid and carbohydrate metabolism in a HFD mouse model. Our findings provide evidence for the traditional use of GBHT as therapy for the management of metabolic syndrome.

Abstract
The hypothesis of this study is that fisetin and phase II conjugated forms of fisetin may partly undergo biliary excretion. To investigate this hypothesis, male Sprague-Dawley rats were used for the experiment, and their bile ducts were cannulated with polyethylene tubes for bile sampling. The pharmacokinetic results demonstrated that the average area-under-the-curve (AUC) ratios ( k (%) = AUCconjugate/AUCfree-form) of fisetin, its glucuronides, and its sulfates were 1:6:21 in plasma and 1:4:75 in bile, respectively. Particularly, the sulfated metabolites were the main forms that underwent biliary excretion. The biliary excretion rate ( kBE (%) = AUCbile/AUCplasma) indicates the amount of fisetin eliminated by biliary excretion. The biliary excretion rates of fisetin, its glucuronide conjugates, and its sulfate conjugates were approximately 144, 109, and 823%, respectively, after fisetin administration (30 mg/kg, iv). Furthermore, biliary excretion of fisetin is mediated by P-glycoprotein.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Metabolic syndrome and vascular dysfunction was suggested to be the risk factors for Alzheimer's disease (AD). Xuefu Zhuyu decoction (XZD) is a traditional Chinese medicine used to treat metabolic syndrome and cardiac-cerebral vascular disease. The effects of XZD on ameliorating metabolic syndrome, amyloid-related pathologies and cognitive impairment in an animal model of AD with metabolic stress was investigated. MATERIALS AND METHOD The animal model of AD with metabolic stress was created by administrating high-fat diet and a low-dose injection of streptozotocin prior to the appearance of senile plaques in APP/PS1 transgenic mice. The diabesity-associated metabolic changes and AD-related pathological alterations were examined. RESULTS We found that XZD reduced body weight, insulin and leptin level, HOMA-IR, hepatic triglyceride, serum Aβ42 in the metabolic stressed AD animal. XZD also ameliorated oral glucose tolerant, Aβ deposition, astrocyte and microglia activation in the vicinity of plaques, and nesting behavior in the metabolic stressed AD animal. CONCLUSION The results of this study suggest that XZD is able to reduce the peripheral metabolic stress-mediated vascular hypoperfusion, neuroinflammation and AD-related pathology in APP/PS1 mice.

Abstract
Sarcandra glabra (Thunb.) Nakai (Chloranthaceae) is a medicinal plant used as herbal tea or food supplement to promote human health. We isolated 14 phenolic compounds from the n-butanol fraction of S. glabra and investigated their anti-inflammatory potential using lipopolysaccharide (LPS)-activated RAW264.7 macrophages. We demonstrated that methyl isorinate, a previously uncharacterized compound in S. glabra, is able to suppress NF-κB activation and reduce the expression of iNOS and COX-2 as well as the phosphorylation of IκB in LPS-treated RAW264.7 cells. In addition, the production of two inflammatory cytokines (IL-6 and TNF-α), as well as release of reactive oxygen species, in the LPS-stimulated macrophages was also inhibited by this compound. Furthermore, the structure-activity relationships of all of the isolated phenolic compounds present were analyzed. Overall, this study revealed several anti-inflammatory compounds that were present in S. glabra, and the results suggest that these diverse phenolic compounds are associated with the anti-inflammatory effects of S. glabra.

Abstract
The purpose of this study was to investigate the pharmacokinetics of the polymethoxylated flavonoids kumatakenin, pachypodol, and retusin, which contain two, three, or four methoxy substitutions, using a validated ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method in rats. The pharmacokinetic results demonstrated that the elimination half-lives for kumatakenin, pachypodol, and retusin were 30 ± 11.6, 39.4 ± 19.5, and 106.9 ± 26 min, respectively, for the low dose group and 54.5 ± 16.5, 33.8 ± 10, and 134.6 ± 34.7 min for the high dose group. The results suggested that the area under the curve values (AUC) for the analytes did not correlate with the number of methoxy groups. Pachypodol had the lowest AUC, which may have been correlated with lipophilicity, for both the low and high dose groups. In conclusion, the polymethoxylated flavonoid pachypodol is more hydrophilic than kumatakenin or retusin, which were correlated with the pharmacokinetic results.

Abstract
TI-HU-YIN (JCKD), a compound composed of many Chinese herbs, is hypothesized to attenuate renal tubular injury and interstitial fibrosis. Moreover, its renoprotective effects were assessed in animal and in vitro studies. First, male C57BL/6 mice were under sham operation or unilateral ureteral obstruction (UUO) surgery, and then treated with phosphate buffer solution (PBS), aliskirin and valsartan (A+V), and JCKD for 14 days. At 7 and 14 days, mice were sacrificed and the kidney tissues were assessed for histopathological changes and transforming growth factor (TGF)-β1 expression. As compared to sham group, UUO-PBS group had more serious tubular dilatation and injury, α-smooth muscle actin-positive areas, F4/80-positive macrophages, and interstitial fibrosis. Impressively, these pathologic changes were significantly attenuated in UUO mice both treated with JCKD and A+V as compared to UUO-PBS group. At 14 days, TGF-β1 expression was significantly suppressed in kidney tissues of UUO-JCKD group as well as in UUO-A+V group. Second, TGF-β1 production was increased in macrophage J774 cells and NRK-52E proximal tubular cells stimulated by angiotensin (Ang)-II at 10 nM for 24 h and at 1 nM for 48 h, respectively. JCKD (≥ 400 μg/ml) inhibited the TGF-β1 production at baseline and stimulated by Ang II in both cell lines. Our study showed that JCKD reduced renal injury, macrophage infiltration and interstitial fibrosis possibly through suppressing the TGF-β1 expression in UUO mice. Accordingly, JCKD is potential to retard the progression of chronic kidney disease. Further studies are needed to validate its renoprotective effects in the inhibition of TGF-β1 expression and the amelioration of renal fibrosis.

Abstract
Abstract
Lung cancer is the most common cancer worldwide. Platinum-based combination chemotherapy is one of first line treatments for patients with lung cancer. Most of the cytotoxic drugs are targeting DNA, interfere with DNA synthesis, and triggering DNA damage response (DDR). Since DDR usually activates important defensive pathways to repair damaged DNA, DDR is known as a key factor determining the outcome of chemotherapy. Among them, RAD51, playing a central role in homologous recombination (HR) DNA repair, has been shown to interfere with the prognosis of patients treated with chemoradiotherapy. Since we have demonstrated that inhibition of RAD51 nuclear focus formation synergistically enhances the anticancer activity of cisplatin, we further screened purified natural products in order to find products with activity to inhibit RAD51 nuclear focus formation. In the present study, we found that a green tea catechin derivative, the (-)-Gallocatechin gallate (GCG) has potent inhibitory activity against RAD51 nuclear focus formation in cisplatin-treated H460 cells. The in vitro cytotoxicity assay showed that the combination of cisplatin or irinotecan with GCG significantly increases the sensitivity of H460 cells to these DNA damage agents. We also evaluated the anti-tumor growth activity of cisplatin or irinotecan in combination with GCG using H460 xenografts. Our results showed that cisplatin and irinotecan suppresses tumor growth by 17.6% and 33.8%, while in combination with GCG suppresses tumor growth by 52.2% and 68.9%, respectively. We further demonstrated that GCG is able to inhibit cisplatin-induced ATM and Chk2 phosphorylation. Together, our results suggest that GCG may interfere with ATM-Chk2 pathway and hence suppress RAD51 nuclear focus formation and DNA repair activities.

Abstract
Maleic acid has been shown to be used as a food adulterant in the production of modified starch by the Taiwan Food and Drug Administration. Due to the potential toxicity of maleic acid to the kidneys, this study aimed to develop an analytical method to investigate the pharmacokinetics of maleic acid in rat blood and kidney cortex. Multiple microdialysis probes were simultaneously inserted into the jugular vein and the kidney cortex for sampling after maleic acid administration (10 or 30 mg/kg, i.v., respectively). The pharmacokinetic results demonstrated that maleic acid produced a linear pharmacokinetic phenomenon within the doses of 10 and 30 mg/kg. The area under concentration versus time curve (AUC) of the maleic acid in kidney cortex was 5-fold higher than that in the blood after maleic acid administration (10 and 30 mg/kg, i.v., respectively), indicating that greater accumulation of maleic acid occurred in the rat kidney.

Abstract
Luteolin and luteolin-7-O-glucoside were isolated from the ethanolic extract of Dendranthema morifolium Ramat Tzvel. The structures of these analytes were identified by nuclear magnetic resonance ((1)H and (13)C NMR) and mass spectrometry. Ethanolic and water extracts contained luteolin-7-O-glucoside at 4.19 and 6.56%, respectively. However, the level of luteolin was only 0.19% in the ethanolic extract, and luteolin was not detected in the water extract. To examine the pharmacokinetics and bioavailability of luteolin and luteolin-7-O-glucoside in rats, parallel studies of luteolin (10 mg/kg, iv; and 100 mg/kg, po) and luteolin-7-O-glucoside (10 mg/kg, iv; and 1 g/kg, po) were conducted. The analytes were detected by high-performance liquid chromatography coupled with a photodiode array detector. A phenyl-hexyl (150 × 4.6 mm iv; 5.0 μm) column was used to separate the analytes from the biological samples. The pharmacokinetic data demonstrate that the areas under the concentration curves (AUCs) of luteolin were 261 ± 33 and 611 ± 89 (min μg/mL) after luteolin administration (10 mg/kg, iv; and 100 mg/kg, po, respectively). The oral bioavailability of luteolin was 26 ± 6%. The AUCs of luteolin-7-O-glucoside were 229 ± 15 and 2109 ± 350 (min μg/mL) after administration of luteolin-7-O-glucoside (10 mg/kg, iv; and 1 g/kg, po, respectively). The oral bioavailability of luteolin-7-O-glucoside was approximately 10 ± 2%. In the group that received luteolin-7-O-glucoside orally, a biotransformed luteolin product was detected, but this product was not detected in the group that received luteolin-7-O-glucoside intravenously. The biotransformation ratio of luteolin to luteolin-7-O-glucoside (the AUC ratio of metabolite/parent compound) was approximately 48.78 ± 0.12%. These results demonstrate that luteolin-7-O-glucoside is primarily hydrolyzed to luteolin in the gastrointestinal tract and then absorbed into the systemic circulation.

Abstract
Indirubin, an active component in the traditional Chinese medicine formula Danggui Longhui Wan, shows promising anticancer effects. Meisoindigo is an analog derived from indirubin, which is less toxic and appears to be even more potent against cancer. In considering meisoindigo as a structural template for the development of new drugs, we designed and synthesized a series of 3-ylideneoxindole acetamides as novel anticancer agents. The acetamides were then evaluated for in vitro and in vivo anticancer activities. The 3-ylideneoxindole acetamides were found to have better anticancer activity than was indirubin-3'-oxime in several cancer cell lines and also displayed a spectrum of activity similar to that of the drug candidate roscovitine, a CDK inhibitor. Among the 3-ylideneoxindole acetamides, compound 10 showed particularly good efficacy. Cell cycle analysis further revealed that compound 10 arrested cells in the G1 phase and caused an increase in the sub-G1 population, indicating that the apoptosis pathway had been induced. In addition, exposure of cells to compound 10 led to the upregulation of the cell-cycle regulator cyclin D1, which was sustained at a high level. In contrast, the same compound induced a short-term elevation in the level of cyclin E, which was followed by a rapid decrease and the attenuation of Rb phosphorylation. Furthermore, a docking model suggests that compound 10 binds to the active site of CDK4. In testing the therapeutic potency of compound 10 on CT26-xenografted BALB/c mice, a significant reduction in tumor size comparable to that of cisplatin was found when administrated via the i.p. route. The mice presented no loss of body weight, indicating that this compound possesses low toxicity. In the future, we are planning in vivo investigations of these new active anticancer agents to better elucidate active mechanisms at the cellular level and thus benefit the development of anticancer therapies.

Abstract
Bubble formulations have both diagnostic and therapeutic applications. However, research on nanobubbles/nanodroplets remains in the initial stages. In this study, a nanodroplet formulation was prepared and loaded with a novel class of chemotherapeutic drug, ie, quercetin, to observe its pharmacokinetic properties and ultrasonic bioimaging of specific sites, namely the abdominal vein and bladder. Four parallel groups were designed to investigate the effects of ultrasound and nanodroplets on the pharmacokinetics of quercetin. These groups were quercetin alone, quercetin triggered with ultrasound, quercetin-encapsulated in nanodroplets, and quercetin encapsulated in nanodroplets triggered with ultrasound. Spherical vesicles with a mean diameter of 280 nm were formed, and quercetin was completely encapsulated within. In vivo ultrasonic imaging confirmed that the nanodroplets could be treated by ultrasound. The results indicate that the initial 5-minute serum concentration, area under the concentration–time curve, elimination half-life, and clearance of quercetin were significantly enhanced by nanodroplets with or without ultrasound.

Abstract
Ractopamine, a β-agonist, is used to increase the proportion of lean meat in livestock. However, due to potential cardiovascular risks, ractopamine has been banned for use in food-producing animals in many countries. Nevertheless, pharmacokinetic studies of ractopamine have not been completed. The aim of this study was to develop a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the determination of ractopamine. This validated method was used to investigate the pharmacokinetics and organ distribution of ractopamine in rats. The validation results complied with the U.S. Food and Drug Administration's standards. The oral bioavailability of ractopamine was 2.99%. After intravenous administration, ractopamine concentrations varied as follows: kidney > lung > spleen > heart > liver > muscle > plasma > brain. Nonlinear pharmacokinetics and strong partitioning into tissues were observed after intravenous administration of ractopamine. These effects may be due to nonlinear elimination via the kidney.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhein is a pharmacological active component found in Rheum palmatum L. that is the major herb of the San-Huang-Xie-Xin-Tang (SHXXT), a medicinal herbal product used as a remedy for constipation. Here we have investigated the comparative pharmacokinetics of rhein in normal and constipated rats. Microarray analysis was used to explore whether drug-metabolizing genes will be altered after SHXXT treatment. MATERIALS AND METHODS The comparative pharmacokinetics of rhein in normal and loperamide-induced constipated rats was studied by liquid chromatography with electrospray ionization tandem mass spectrometry (LC-MS/MS). Gene expression profiling in drug-metabolizing genes after SHXXT treatment was investigated by microarray analysis and real-time polymerase chain reaction (RT-PCR). RESULTS A validated LC-MS/MS method was applied to investigate the comparative pharmacokinetics of rhein in normal and loperamide-induced constipated rats. The pharmacokinetic results demonstrate that the loperamide-induced constipation reduced the absorption of rhein. Cmax significantly reduced by 2.5-fold, the AUC decreased by 27.8%; however, the elimination half-life (t1/2) was prolonged by 1.6-fold. Tmax and mean residence time (MRT) were significantly prolonged by 2.8-fold, and 1.7-fold, respectively. The volume of distribution (Vss) increased by 2.2-fold. The data of microarray analysis on gene expression indicate that five drug-metabolizing genes, including Cyp7a1, Cyp2c6, Ces2e, Atp1b1, and Slc7a2 were significantly altered by the SHXXT (0.5 g/kg) treatment. CONCLUSION The loperamide-induced constipation reduced the absorption of rhein. Since among the 25,338 genes analyzed, there were five genes significantly altered by SHXXT treatment. Thus, information on minor drug-metabolizing genes altered by SHXXT treatment indicates that SHXXT is relatively safe for clinical application.

Abstract
Rhein (4,5-dihydroxy-9,10-dioxoanthracene-2-carboxylic acid, cassic acid) is a pharmacological active component found in Rheum palmatum L. the major herb of San-Huang-Xie-Xin-Tang (SHXXT), a medicinal herbal product used as a remedy for constipation. Here we have determined multiple bioactive components in SHXXT and investigated the comparative pharmacokinetics of rhein in rats. A sensitive and specific method combining liquid chromatography with electrospray ionization tandem mass spectrometry has been developed and validated to simultaneously quantify six active compounds in the pharmaceutical herbal product SHXXT to further study their pharmacokinetics in rats. Multiple reaction monitoring (MRM) was employed for quantification with switching electrospray ion source polarity between positive and negative modes in a single run. There were no significant matrix effects in the quantitative analysis and the mean recovery for rhein in rat plasma was 91.6%±3.4%. The pharmacokinetic data of rhein demonstrate that the herbal formulae or the single herbal extract provide significantly higher absorption rate than the pure compound. This phenomenon suggests that the other herbal ingredients of SHXXT and rhubarb extract significantly enhance the absorption of rhein in rats. In conclusion, the herbal formulae (SHXXT) are more efficient than the single herb (rhubarb) or the pure compound (rhein) in rhein absorption.

Abstract
Five new diaryldimethylbutane lignans, saurulignans A-E (1-5), four new tetrahydrofuran lignans, saurufurins A-D (6-9), and one arylnaphthalene lignan, saurunarin (10), were isolated from Saururus chinensis, along with 18 known compounds. Lignan 5 showed significant inhibition of ADP-induced aggregation with an IC50 value of 9.8 μM and AA-induced aggregation with an IC50 value of 14.0 μM. Compound 19 showed significant activity to inhibit PAF-induced aggregation with an IC50 value of 9.1 μM. In addition, five isolated compounds could induce platelet aggregation. These results suggest that secondary metabolites in S. chinensis have bidirectional regulation on blood clotting and anticlotting effects.

Abstract
Abstract
Objective
The aim of this study was to compare the oral bioavailability and pharmacokinetic data between pure compound of the major active component, single herbal extract and complex herbal formulation by determining bioavailability of geniposide in each group following intravenous and oral administrations.
Methods
A conscious and freely moving rat model was used in this experiment to avoid the stress caused by restraint or anaesthesia. The pure compound of geniposide, Gardenia fruits (Chinese name: Zhi-Zi), and extracts of a Gardenia herbal formulation (Chinese name: Zhi-Zi-Chi-Tang) were administered at doses of 200 mg/kg, 4.69 g/kg and 10.82 g/kg for oral administration and fed by gavages to rats, respectively. The earlier doses are equivalent to geniposide administration dose of 200 mg/kg.
Key findings
The results show that after oral administration of geniposide, Gardenia fruits and Gardenia herbal formulation, the bioavailability were 4.23%, 32.32% and 27.17%, respectively. The results of oral bioavailability of geniposide also suggest that Gardenia fruits extract, single herb, is a more efficient way for geniposide, pure compound, absorption than traditional herbal formulation administration and direct pure compound administration.
Conclusions
The conclusion reveals that herbal ingredient–ingredient or herb–herb interaction may affect the oral absorption of geniposide-related herbal formulation.

Abstract
Epimedin C, an ingredient of Herba Epimedii, has potential for treatment of cardiovascular disease and bone loss. However, there is still no sensitive analytical method to monitor epimedin C in biological samples. The goal of this study was to develop a sensitive and reliable method based on a LC-MS/MS for evaluating the pharmacokinetics of epimedin C after administration of Herba Epimedii in rat. Electrospray ionization in positive-ion mode and multiple reaction monitoring were used to identify and quantitate active components. Analytes were separated by a reverse-phase C18 column. Liquid-liquid extraction using ethyl acetate, evaporation and reconstitution was used to plasma sample preparation. Mass transition of precursor ion → product ion pairs were monitored at m/z 823.4 → 313.1 for epimedin C and m/z 237.1 → 178.9 for carbamazepine (internal standard). A calibration curve gave good linearity (r > 0.999) over the concentration range 2.5-500 ng/mL. Pharmacokinetic data demonstrated that there was rapid distribution and slow elimination after epimedin C administration (1 mg/kg, i.v.). Oral bioavailabilities of epimedin C in the pure compound and in the Herba Epimedii were around 0.58% and 0.13%, respectively. The result suggests that other herbal ingredients of Herba Epimedii may suppress the oral bioavailability of epimedin C.

Abstract
Di-(2-ethylhexyl) phthalate (DEHP) is used to increase the flexibility of plastics for industrial products. However, the illegal use of the plasticizer DEHP in food and drinks has been reported in Taiwan in 2011. In order to assess the exact extent of the absorption of DEHP via the oral route, the aim of this study is to develop a reliable and validated ultra performance liquid chromatography with tandem mass spectrometry (UPLC-MS/MS) method to evaluate the oral bioavailability of DEHP in rats. The optimal chromatographic separation of DEHP and butyl benzyl phthalate (BBP; used as internal standard) were achieved on a C₁₈ column. The mobile phase was consisted of 5 mM ammonium acetate-methanol (11:89, v/v) with a flow rate of 0.25 mL/min. The monitoring ion transitions were m/z 391.4 → 149.0 for DEHP and m/z 313.3 → 149.0 for BBP. The mean matrix effects of DEHP at low, medium and high concentrations were 94.5 ± 5.7% and 100.1 ± 2.3% in plasma and feces homogenate samples, respectively. In conclusion, the validated UPLC-MS/MS method is suitable for analyzing the rat plasma sample of DEHP and the oral bioavailability of DEHP was about 7% in rats.

Abstract
Epimedium sagittatum (Sieb. et Zucc.) Maxim is one of the herbs used to treat erectile dysfunction in Traditional Chinese Medicine. Sildenafil is a phosphodiesterase 5 inhibitor used to treat erectile dysfunction in Western Medicine. This study evaluates the herbal-drug interaction of Epimedium sagittatum extract on the pharmacokinetics of sildenafil in rats by ultra-performance liquid chromatography. The rat plasma was sampled from each anesthetized rat after pretreatment with 3-days Epimedium sagittatum extract (1/2 g/kg/day) and intravenous injection with sildenafil (10/30 mg/kg). The pharmacokinetic data demonstrate that the area under the concentration-time curve (AUC) of sildenafil (10 mg/kg) was significantly decreased in groups that received a high dose of Epimedium sagittatum extract. In conclusion, the study demonstrates that there was significant herb-drug interaction of Epimedium sagittatum extract on the pharmacokinetics of sildenafil at low and high daily doses, suggesting co-administration use of Epimedium sagittatum extract and sildenafil in clinical practice should be prevented due to possible herb-drug interactions.

Abstract
Dang-shen, radix Codonopsis is one of the best-known traditional Chinese medicines and is used mainly as a tonic agent. Nine commercial products belong to three species of Codonopsis genus, Codonopsis tangshen, Codonopsis pilosula var. modesta and a cultivated species of Codonopsis pilosula, which were purchased from drug stores in Taipei and Taichung, Taiwan. To determine the chemical differences between samples of Dang-shen, a method combining solvent partition and HPLC-UV was used. An enriched fraction of n-butanol was obtained, after partition. Then, the chemical profile was determined using a C18 reversed column chromatography in a gradient solvent system with 10-40% acetonitrile in 0.1% formic acid, for 60 min. A comparison of the constituents in the nine commercial products of Dang-shen showed that compounds codonopyrrolidum A, B and codonoside A only exist in C. tangshen, but not in C. pilosula var. modesta and C. pilosula. A predominate compound, codonopyrrolidum A, can be used to distinguish the herbs, C. tangshen from C. pilosula var. modesta and C. pilosula. Low secondary metabolite content was found in the cultivated species of C. pilosula.

Abstract
Two new alkaloids, 2-demethyl-oxypalmatine (1) and 5-ethoxycarbonylsinoracutine (2), were isolated from the rhizomes of Sinomenium acutum, along with thirty-four known compounds. Cytotoxicity of the isolated compounds was examined for the MCF-7, H460, HT-29, and CEM human cancer cell lines. Dauriporphine (16), 6-O-demethylmenisporphine (17), bianfugecine (18), menisporphine (19), and 6-O-demethyldauriporphine (20) showed differential effects in their cytotoxic activity on the target cancer cell lines. Significant angiogenesis inhibitions of 16 and 19 were also observed.

Abstract
In view of the limited information on the pharmacokinetics of oseltamivir (OSE) during pregnancy, this study aims to evaluate the placental transportation of OSE and its active metabolite oseltamivir carboxylic acid (OCA) in rats. A validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) system coupled to an in vivo transplacental model has been developed to determine OSE and OCA in the placenta, amniotic fluids and fetus of 13-day pregnant Sprague-Dawley rats. Concentrations of OSE and OCA in plasma, amniotic fluids, placenta, and fetus were measured by the validated LC-MS/MS after OSE administration (10 mg/kg, iv). The pharmacokinetic data of both analytes were examined by non-compartmental modeling. The area under the concentration-time curve (AUC) of OCA in maternal plasma was found to be 3.6 times larger than that of OSE. The AUCs of OCA in both amniotic fluid and fetus were significantly decreased, in comparison with that in maternal plasma (reduced by 76.7 and 98.1%, respectively). We found that both OSE and OCA can penetrate the placenta, amniotic fluids and fetus in rats during pregnancy; however, the penetration of OCA was much lower than that of OSE. The mother-to-fetus transfer ratio was defined as AUCfetus/AUCmother. The data demonstrated that the mother-to-fetus transfer ratio of OSE and OCA were 1.64 and 0.019, respectively, suggesting that OSE, but not OCA, penetrated through the placenta. Moreover, OCA might not be easily metabolized in the fetus due to the lack of carboxylase in the fetus.

Abstract
Bu-yang-huan-wu-tang (BYHWT) is one of the most popular formulated traditional Chinese medicine prescriptions, and is widely for prevention of ischemic cardio-cerebral vascular diseases and stroke-induced disability. A specific high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) has been developed and validated for simultaneous quantification of the nine main bioactive components, i.e., astragaloside I, astragaloside II, astragaloside IV, formononetin, ononin, calycosin, calycosin-7-O-β-d-glucoside, ligustilide and paeoniflorin in rat plasma after oral administration of BYHWT extract. This method was applied to investigate the pharmacokinetics in conscious and freely moving rats. No significant matrix effects were observed. The overall analytical procedure was rapid and reproducible, which makes it suitable for quantitative analysis of a large number of samples. Among them, three astragalosides and four isoflavones in A. membranaceus, ligustilide in Radix Angelicae Sinensis and Rhizoma Ligustici Chuanxiong and paeoniflorin in Radix Paeoniae Rubra were identified. This developed method was then successfully applied to pharmacokinetic studies of the nine bioactive constituents after oral administration of BYHWT extracts in rats. The pharmacokinetic data demonstrated that astragaloside I, astragaloside II, astragaloside IV and ligustilide presented the phenomenon of double peaks. The other herbal ingredients of formononetin, ononin, calycosin, calycosin-7-O-β-d-glucoside and paeoniflorin appeared together in a single and plateau absorption phase. These phenomenona suggest that these components may have multiple absorption sites, regulation of enterohepatic circulation or the gastric emptying rate, or there is ingredient-ingredient interaction. These pharmacokinetic results provide a constructive contribution to better understand the absorption mechanism of BYHWT and to support additional clinical evaluation.

Abstract
Background Polylactic-co-glycolic acid (PLGA) nanoparticles have been used to increase the relative oral bioavailability of hydrophobic compounds and polyphenols in recent years, but the effects of the molecular weight of PLGA on bioavailability are still unknown. This study investigated the influence of polymer molecular weight on the relative oral bioavailability of curcumin, and explored the possible mechanism accounting for the outcome. Methods Curcumin encapsulated in low (5000–15,000) and high (40,000–75,000) molecular weight PLGA (LMw-NPC and HMw-NPC, respectively) were prepared using an emulsification-solvent evaporation method. Curcumin alone and in the nanoformulations was administered orally to freely mobile rats, and blood samples were collected to evaluate the bioavailability of curcumin, LMw-NPC, and HMw-NPC. An ex vivo experimental gut absorption model was used to investigate the effects of different molecular weights of PLGA formulation on absorption of curcumin. High-performance liquid chromatography with diode array detection was used for quantification of curcumin in biosamples. Results There were no significant differences in particle properties between LMw-NPC and HMw-NPC, but the relative bioavailability of HMw-NPC was 1.67-fold and 40-fold higher than that of LMw-NPC and conventional curcumin, respectively. In addition, the mean peak concentration (Cmax) of conventional curcumin, LMw-NPC, and HMw-NPC was 0.028, 0.042, and 0.057 μg/mL, respectively. The gut absorption study further revealed that the HMw-PLGA formulation markedly increased the absorption rate of curcumin in the duodenum and resulted in excellent bioavailability compared with conventional curcumin and LMw-NPC. Conclusion Our findings demonstrate that different molecular weights of PLGA have varying bioavailability, contributing to changes in the absorption rate at the duodenum. The results of this study provide the rationale for design of a nanomedicine delivery system to enhance the bioavailability of water-insoluble pharmaceutical compounds and functional foods.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Gentiopicroside (GPS) is a secoiridoid glucoside isolated from the ethanol extract of Gentianae Radix with a content of 13%, which has been used for centuries in Chinese as a digestive aid. AIM OF THE STUDY This study investigates the pharmacokinetics of GPS and its metabolic pathway for the liver ischemia/reperfusion (I/R) in rats. MATERIALS AND METHODS The experimental animals were anesthetized intraperitoneally (i.p.) with a mixture of urethane (1.0 g/kg) and α-chloralose (0.1 g/kg). A midline laparatomy was performed and the liver hilum was gently exposed. All structures in the portal triad (hepatic artery, portal vein, and bile duct) to the left and median liver lobes were occluded with silk thread for 30 min. Ischemia was followed by a sudden reperfusion after removing the occluding threads. After 60 min reperfusion, the rats received a single intravenous 5 mg/kg dose of GPS. RESULTS The area under concentration curve (AUC) was significantly increased; however, the clearance (Cl) was significantly decreased in the liver I/R rats. Furthermore, after pretreated with SKF-525A (50 mg/kg, i.p.), a cytochrome P450 (CYP) inhibitor, AUC, elimination half-life (t(1/2)) and the mean residence time (MRT) of GPS in rat blood were significantly increased, suggesting that CYP was involved in the metabolism of GPS. For the group without liver I/R, GPS was administered at doses of 5 mg/kg and 100 mg/kg intravenously and orally, respectively. The pharmacokinetic results indicated that the AUC was 565±95.1 and 1163±273 min μg/mL and the t(1/2) of GPS was 71±9 and 106±17 min after intravenous and oral administration, respectively. The oral bioavailability of GPS was 10.3±2.4% in the rats. CONCLUSIONS The status of I/R might prolong the disposition of GPS, and the plasma concentration of GPS in the liver I/R injury rats was significantly increased. The increased body exposure of GPS in the treatment of liver I/R may result from the decreased metabolism of GPS mediated by CYP in the liver.

Abstract
Neobavaisoflavone (NBIF) is an isoflavone isolated from Psoralea corylifolia L, a plant claimed to have osteogenic activity and used to treat bone fractures, osteomalacia and osteoporosis. The present results showed that NBIF concentration-dependently promoted osteogenesis in MC3T3-E1cells, demonstrated by notable enhancement of alkaline phosphatase (ALP) activity, increase of bone-specific matrix proteins expression including type I collagen (Col-I), osteocalcin (OCN) and bone sialoprotein (BSP), and formation of bone nodules. However, cell proliferation in the presence of NBIF was not affected. Results also demonstrated that NBIF up-regulated the expression of runt-related transcription factor 2 (Runx2) and Osterix (Osx), the bone-specific transcription factors participating in regulation of bone marker genes expression. Application of p38 inhibitor SB203580 repressed not only NBIF-induced activation of ALP, the expression of Col-I, OCN and BSP, but also the matrix proteins mineralization. Western blot analysis further revealed that NBIF increased the phosphorylated level of p38 concentration-dependently. Additionally, inhibition of p38 abolished the stimulatory effect of NBIF on the expression of Runx2 and Osx. Taken together, the osteogenic activity of NBIF might probably act through activation of p38-dependent signaling pathway to up-regulate the mRNA levels of Runx2 and Osx then stimulate bone matrix proteins expression. The beneficial effect of NBIF on mineralization demonstrated that NBIF represented as an active component existed in P. corylifolia and might be a potential anabolic agent to treat bone loss-associated diseases.
