Abstract
Berberine (Brb) and piperine (Pip) are salient examples of bioactive nutraceuticals possessing a promising role in controlling epilepsy. However, during the development of novel nanoformulation that augments their effects, an adequate determination of each one separately was a challenge since they have nearly the same detection wavelength and diverse solubility profiles. Consequently, a tailored high-performance liquid chromatography technique was developed for their simultaneous detection in routine analyses. The chromatographic separation was achieved using a C18 column. The linear gradient flow of acetonitrile: 0.1%v/v aqueous phosphoric acid was altered from 55:45 to 80:20 v/v over 3 min at a 1.2 mL/min flow rate until the end of the run. Brb and Pip were eluted at 1.6 and 3.4 min, respectively. The linearity of the standard curves was found to be ≥0.999, and the mean % recovery for Brb and Pip lay within the accepted limit. Moreover, the percentage coefficient of variation was <2% for intra- and inter-day precision. Consequently, the developed assay was successfully applied for the quantification of both drugs rapidly with high resolution and minimum interference from each other during the different steps conducted during the nanoformulation development.

Intharuksa A, Arunotayanun W, Yooin W, Sirisa-ard P. A Comprehensive Review of Andrographis paniculata (Burm. f.) Nees and Its Constituents as Potential Lead Compounds for COVID-19 Drug Discovery. Molecules 2022; 27:molecules27144479. [PMID: 35889352 PMCID: PMC9316804 DOI: 10.3390/molecules27144479] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 07/05/2022] [Accepted: 07/11/2022] [Indexed: 11/17/2022] Open
Abstract
The COVID-19 pandemic has intensively disrupted global health, economics, and well-being. Andrographis paniculata (Burm. f.) Nees has been used as a complementary treatment for COVID-19 in several Asian countries. This review aimed to summarize the information available regarding A. paniculata and its constituents, to provide critical points relating to its pharmacological properties, safety, and efficacy, revealing its potential to serve as a source of lead compounds for COVID-19 drug discovery. A. paniculata and its active compounds possess favorable antiviral, anti-inflammatory, immunomodulatory, and antipyretic activities that could be beneficial for COVID-19 treatment. Interestingly, recent in silico and in vitro studies have revealed that the active ingredients in A. paniculata showed promising activities against 3CLpro and its virus-specific target protein, human hACE2 protein; they also inhibit infectious virion production. Moreover, existing publications regarding randomized controlled trials demonstrated that the use of A. paniculata alone or in combination was superior to the placebo in reducing the severity of upper respiratory tract infection (URTI) manifestations, especially as part of early treatment, without serious side effects. Taken together, its chemical and biological properties, especially its antiviral activities against SARS-CoV-2, clinical trials on URTI, and the safety of A. paniculata, as discussed in this review, support the argument that A. paniculata is a promising natural source for drug discovery regarding COVID-19 post-infectious treatment, rather than prophylaxis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zhuanggu Guanjie Pill (ZGGJP), a modern Chinese medicine formula, is composed of 12 herbs and has been used to treat osteoporosis in China for almost 30 years. However, no in vivo study of the influences of ZGGJP on the cytochrome P450 (CYP) activities have been reported. AIM OF THE STUDY The aim of this study was to evaluate the effects of ZGGJP on the activities and the mRNA expression of CYP enzymes (CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and CYP3A) and their corresponding nuclear receptor levels in rats. MATERIALS AND METHODS After 7 days oral treatment of ZGGJP at low- and high-dose, cocktail solution was given to rats. Blood samples were collected at series of time points. The plasma concentrations of probe drugs and their corresponding metabolites were determined by UPLC-MS/MS. The influence of ZGGJP on the activities of seven CYPs were evaluated the metabolic ratios (Cmax and AUC0-t) for metabolites/probe drugs. In addition, the effects of ZGGJP on the mRNA expression of CYPs and their corresponding nuclear receptors in rat liver were evaluated by real-time PCR. RESULTS ZGGJP showed significant inductive effects on CYP1A2 and CYP2B6 of both male and female rats. The influence of ZGGJP on CYP2C9 and CYP3A showed gender difference. ZGGJP could induce the activities of CYP2C9 and CYP3A in female rats, but have no influence on the activities in male rats. ZGGJP had no effects on CYP2D6, CYP2C19 and CYP2E1. The mRNA expression results of CYPs were in accordance with the pharmacokinetic results. The mRNA expression levels of constitutive androstane receptor (CAR) and vitamin D receptor (VDR) were increased significantly in female rats at high dosage, but no significant changes were observed in male rats. CONCLUSION ZGGJP had inductive effects on CYP1A2 and CYP2B6 in both male and female rats. The results showed that ZGGJP could induce the activities of CYP2C9 and CYP3A in female rats, but had no effect in male rats. This may suggest that the influence of ZGGJP on CYP2C9 and CYP3A exhibit gender difference. The inductive effects of ZGGJP on the activities of CYPs, exhibiting gender difference, may be regulated by CAR and VDR. Therefore, co-administration of ZGGJP with other drugs, especially using CYP2C9 and CYP3A substrates in females, may need dose adjustment to avoid herb-drug interaction.

Thomas AB, Choudhary DC, Raje A, Nagrik SS. Pharmacokinetics and Pharmacodynamic Herb-Drug Interaction of Piperine with Atorvastatin in Rats. J Chromatogr Sci 2021; 59:371-380. [PMID: 33434916 DOI: 10.1093/chromsci/bmaa126] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 10/27/2020] [Accepted: 12/02/2020] [Indexed: 11/13/2022]
Abstract
Herbals that are widely consumed as therapeutic alternatives to conventional drugs for cardiovascular diseases, may lead to herb-drug interactions (HDIs). Atorvastatin (ATR) is drug of choice for hyperlipidemia and is extensively metabolized through CYP3A4 enzyme. Thus, we postulate that concomitant administration of ATR with piperine (PIP, potent inhibitor of CYP3A4 enzyme)/ridayarishta (RID, cardiotonic herbal formulations containing PIP) may lead to potential HDI. A simple, accurate, sensitive high-performance liquid chromatography-photodiode array detection method using Kromasil-100 C18 column, mobile phase acetonitrile: 30 mM phosphate buffer (55:45 v/v) pH 4.5 with flow rate gradient programming was developed to study the potential HDI in rats. Method was found to be linear (2-100 ng/mL) with Lower Limit of Detection (LLOD) 2 ng/mL. The precision (%CV < 15%), accuracy (-1.0 to -10% R.E) with recoveries above 90% from rat plasma of ATR and IS were obtained. The pharmacokinetic (PK) interactions studies on co-administration of ATR (8.4 mg/kg, p.o.) with PIP (35 mg/kg, p.o.), demonstrated a threefold increase in Cmax of ATR (P < 0.01) with significant increase in AUC0-t/AUC0-∞ compared to ATR alone indicating potential PK-HDI. However co-administration of RID (4.2 mL/kg, p.o.) showed less significant changes (P > 0.05) indicating low HDI. The pharmacodynamic effects/interactions study (TritonX-100 induced hyperlipidemic model in rats) suggested no significant alterations in the lipid profile on co-administration of PIP/RID with ATR, indicating that there may be no significant pharmacodynamic interactions.

Abstract
Natural compounds such as herbal medicines and/or phyto-compounds from foods, have frequently been used to exert synergistic therapeutic effects with anti-brain disorder drugs, supplement the effects of nutrients, and boost the immune system. However, co-administration of natural compounds with the drugs can cause synergistic toxicity or impeditive drug interactions due to changes in pharmacokinetic properties (e.g., absorption, metabolism, and excretion) and various drug transporters, particularly brain transporters. In this review, natural compound–drug interactions (NDIs), which can occur during the treatment of brain disorders, are emphasized from the perspective of pharmacokinetics and cellular transport. In addition, the challenges emanating from NDIs and recent approaches are discussed.

Abstract
Background Arishta technology is an age-old heritage and uses herbal decoctions to prepare self-generated alcoholic medicines. In Ayurveda, Arishta preparations are widely used as a remedy for metabolic disorders. However, their safety and influence on herb metabolism pathways were not yet explored. Aim: To study the subacute toxicity of a polyherbal Arishta formulation (coded as DB-07) in rats and to evaluate its potential for inhibition of the drug-metabolizing enzyme (Cytochrome P450 3A4). Methodology Experimentally naive rats were treated with graded oral doses of DB-07 (10 and 20 mL/kg/day) for 28 days. During the course of the experiment, all the animals were closely observed for apparent behavioural abnormalities and mortalities. Tissue histology was performed to assess any sign of toxicity. In addition, in vitro CYP3A4 inhibition assay was performed to study the effect on drug metabolism pathways. Results Animals did not show any change in body weight, organ toxicity and food consumption throughout the dosing period of 28 days. Pathophysiological, behavioural status and locomotor activity were not altered. DB-07 did not inhibit CYP3A4 enzyme and drug metabolism pathway in-vitro. Gallic acid and quercetin were identified as phytomarker from the formulation that may be responsible for its activity related safety issue. Conclusion These results indicate that use of DB-07 may be safe with no sign of toxicity for up to 28 days in rats. Further, CYP3A4 inhibition assay indicated that DB-07 is less likely to have herb-drug interactions when concomitantly administered with CYP3A4 inhibitors or inducer.

Abstract
BACKGROUND Guggulutiktaka ghritam is an ayurvedic medicine which has been traditionally used to treat various chronic inflammatory conditions. However, the mechanism of action of the Ayurvedic medication in control of inflammatory conditions has not been clearly evaluated. OBJECTIVE In the current study, the effect of the Guggulutiktaka ghritam extract (GTG) on the lipoxygenase pathway and in the production of proinflammatory cytokines involved in the pathogenesis of chronic inflammation was studied. MATERIALS AND METHODS The effect of GTG in the production of leukotriene was determined by enzyme inhibition studies on 12- lipoxygenase. The assay was carried out by ferrous oxidation of xylenol orange (FOX assay) and was compared to a positive control nordihydroguaiaretic acid. The effect of GTG on the production of proinflammatory cytokines TNF-α and IL-1β in monocytes were studied. For this, the monocytes were pretreated with various concentrations of GTG and subsequently stimulated with lipopolysaccharide. The cytokines TNF-α and IL-1β produced were quantified by ELISA and the results were compared to positive controls Rolipram and Dexamethasone respectively. The gene expression studies were carried out using qRT-PCR. The IC50 values were calculated and evaluated statistically. RESULTS The result indicates that GTG in comparison to the positive control Nordihydroguaiaretic acid significantly reduced the activity of 12- lipoxygenase. Also, there was significant inhibition in the production of proinflammatory cytokines in LPS stimulated monocytes pretreated with GTG as compared to positive control Rolipram and Dexamethasone. There was significant downregulation of IL-1β gene in LPS stimulated monocytes pretreated with GTG as compared to control. These changes are further supported by Raman spectra obtained for GTG treated and untreated cells. CONCLUSION The study revealed that GTG is a leukotriene and cytokine inhibitor. The inhibition in the production of cytokines may be due to the down-regulation of genes for TNF-α and IL-1β. The study provides a scientific validation on the possible anti-inflammatory mechanism of action of this traditionally used medicine. Identification of bioactive molecules would aid in developing newer therapeutics for control of chronic inflammation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Baoyuan decoction (BYD), a traditional Chinese medicine (TCM) formula, is composed of four herbs and widely used with western drugs to treat coronary heart disease, aplastic anemia and chronic renal failure in clinic. However, no study of the effect of BYD on the cytochrome P450 (CYP) activities has been reported. AIM OF THE STUDY The purpose of the present study was to evaluate the potential influences of BYD on the activities of seven CYP isozymes (CYP1A2, 2B6, 2C9, 2C19, 2D6, 2E1, and 3A4) in rats. MATERIALS AND METHODS A sensitive and selective UPLC-MS/MS method for simultaneous determination of seven probe drugs and internal standard (IS) in rat plasma was developed and validated. The influence of BYD on the activities of CYP isozymes and mRNA expression levels were carried out by comparing plasma pharmacokinetics and real-time reverse transcription-polymerase chain reaction (RT-PCR) of probe drugs between control and BYD treatment groups respectively. RESULTS The calibration curve were linear, with correlation coefficient (r) > 0.99 for seven probe drugs. The intra and inter-assay accuracy and precision of the method were within ± 14.9% and the recoveries ranged from 83.2% to 106.1%. Compared with control group, BYD at low (1.46 g/kg) and high (7.30 g/kg) dosages could significantly increase Cmax and AUC0-t of chlorzoxazone and testosterone, while decrease AUC0-t of phenacetin at high dosage and increase AUC0-t of tolbutamide and metoprolol. Additionally, BYD had increased AUC0-t of bupropion at low dosage and decreased it at high dosage. The mRNA expression results were in accordance with those of pharmacokinetic. CONCLUSION BYD exhibited inhibitory effects on CYP2C9, CYP2E1, and CYP3A4. Moreover, BYD had induction effects on CYP1A2, and CYP2D6 activities. However, no significant change in CYP2C19 activity was observed. It would be useful for the safe and effective usage of BYD in clinic.

Abstract
Withaferin A (WFA), a withanolide derived from medicinal plant Withania somnifera, possesses anti-tumorigenic and immunomodulatory activities against various cancer cells. However, the role of WFA in myocardial ischemia reperfusion (MI/R) injury remains unclear. In the present study, we determined whether WFA may regulate cardiac ischemia reperfusion injury and elucidate the underlying mechanisms. We demonstrated that WFA enhanced H9c2 cells survival ability against simulated ischemia/reperfusion (SI/R) or hydrogen peroxide (H2O2)-induced cell apoptosis. In addition, the enhanced oxidative stress induced by SI/R was inhibited by WFA. Among the multiple antioxidant molecules determined, antioxidants SOD2, SOD3, Prdx-1 was obviously upregulated by WFA. When Akt inhibitor IV was administrated, WFA's suppression effect on oxidative stress was obviously abolished. Additional experiments demonstrated that WFA successfully inhibited H2O2 induced upregulation of SOD2, SOD3, and Prdx-1, ameliorated cardiomyocyte caspase-3 activity via an Akt dependent manner. Collectively, these results support the therapeutic potential of WFA against cardiac ischemia reperfusion injury and highlight the application of WFA in cardiovascular diseases holding great promise for the future.

The enhancement of cardiotoxicity that results from inhibiton of CYP 3A4 activity and hERG channel by berberine in combination with statins. Chem Biol Interact 2018; 293:115-123. [PMID: 30086269 DOI: 10.1016/j.cbi.2018.07.022] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Revised: 05/25/2018] [Accepted: 07/23/2018] [Indexed: 11/24/2022]
Abstract
Metabolism of most endogenous and exogenous compounds is usually produced by the oxidation of cytochrome P450. Due to drug-drug interactions caused by the inhibition or induction of cytochrome P450 enzymes, changes in drug metabolism are the major causes of drug toxicity, CYP3A4 is one of the key isozymes, and involved in the metabolism of over 60% of clinical drugs. Human ether-a-go-go related genes (hERG) potassium channel is the most important target of many drugs and plays an important role in cardiac repolarization. Blockade of this channel may lead to long QT syndrome (LQTS), leading to sudden cardiac death. Therefore, it is necessary to evaluate the inhibitory properties of drugs on cytochrome P450 enzymes and hERG channel. We primarily evaluate the safety of berberine in combination with statins. Based on these findings, berberine in combination with statins has a greater inhibitory effect on CYP3A4 activity and CYP3A4 protein and mRNA expression than berberine alone. Simvastatin and atorvastatin reduce hERG current by accelerating channel inactivation. At the same time, the inhibitory effect of berberine and statin combination increased on hERG current by reducing the time constant of inactivation than the single drug alone. These results indicate that berberine in combination with statins can increase cardiotoxicity by inhibiting CYP3A4 and hERG channel.

Abstract
With more and more popular use of traditional herbal medicines, in particular Chinese herbal medicines, herb-drug interactions have become a more and more important safety issue in the clinical applications of the conventional drugs. Researches in this area are increasing very rapidly. Herb-drug interactions are complicated due to the fact that multiple chemical components are involved, and these compounds may possess diverse pharmacological activities. Interactions can be in both pharmacokinetics and pharmacodynamics. Abundant studies focused on pharmacokinetic interactions of herbs and drugs. Herbs may affect the behavior of the concomitantly used drugs by changing their absorption, distribution, metabolism, and excretion. Studies on pharmacodynamics interactions of herbs and drugs are still very limited. Herb-drug interactions are potentially causing changes in drug levels and drug activities and leading to either therapeutic failure or toxicities. Sometime it can be fatal. The exposures to drugs, lacking of knowledge in the potential adverse herb-drug interactions, will put big risk to patients' safety in medical services. On the contrary, some interactions may be therapeutically beneficial. It may be used to help develop new therapeutic strategies in the future. This chapter is trying to review the development in the area of herb-drug interactions based on the recently published research findings. Information on the potential interactions among the commonly used Chinese medicinal herbs and conventional drugs is summarized in this chapter.
