[PMID: 37358659 DOI: 10.1007/s10753-023-01855-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 06/03/2023] [Accepted: 06/05/2023] [Indexed: 06/27/2023]
Abstract
Bavachinin (BVC) is a natural small molecule from the Chinese herb Fructus Psoraleae. It exhibits numerous pharmacological effects, including anti-cancer, anti-inflammation, anti-oxidation, anti-bacterial, anti-viral, and immunomodulatory properties. BVC may serve as a novel drug candidate for the treatment of rheumatoid arthritis (RA). Nevertheless, the effects and mechanisms of BVC against RA are still unknown. BVC targets were selected by Swiss Target Prediction and the PharmMapper database. RA-related targets were collected from the GeneCards, OMIM, DrugBank, TTD, and DisGeNET databases. PPI network construction and enrichment analysis were conducted by taking the intersection target of BVC targets and RA-related targets. Hub targets were further screened using Cytoscape and molecular docking. MH7A cell lines and collagen-induced arthritis (CIA) mice were used to confirm the preventive effect of BVC on RA and its potential mechanism. Fifty-six RA-related targets of BVC were identified through databases. These genes were primarily enriched in PI3K/AKT signaling pathway according to KEGG enrichment analysis. Molecular docking analysis suggested that BVC had the highest binding energy with PPARG. The qPCR and western blotting results showed that BVC promoted the expression of PPARG at both the mRNA level and protein level. Western blotting indicated that BVC might affect MH7A cell functions through the PI3K/AKT pathway. Furthermore, treatment with BVC inhibited the proliferation, migration, and production of inflammatory cytokines in MH7A cells and induced cell apoptosis to a certain extent. In vivo, BVC alleviated joint injury and inflammatory response in CIA mice. This study revealed that BVC may inhibit the proliferation, migration, and production of inflammatory cytokines in MH7A cells, as well as cell apoptosis through the PPARG/PI3K/AKT signaling pathway. These findings provide a theoretical foundation for RA therapy.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 313:116534. [PMID: 37127140 DOI: 10.1016/j.jep.2023.116534] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Revised: 02/24/2023] [Accepted: 04/19/2023] [Indexed: 05/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In traditional oriental medicine, the dried seeds of Psoralea corylifolia L. (PC) have been used to treat various diseases, including gastrointestinal, urinary, orthopedic, diarrheal, ulcer, and inflammatory disorders. AIM OF THE STUDY Although its various biological properties are well-known, there is no information on the therapeutic effects and bioavailable components of PC against inflammatory bowel disease. Therefore, we focused on the relationship between hydroethanolic extract of PC (EPC) that ameliorates colitis in mice and bioactive constituents of EPC that suppress pro-inflammatory cytokines in macrophages. MATERIALS AND METHODS We investigated the therapeutic effects of EPC in a dextran sulfate sodium-induced colitis mouse model and identified the orally absorbed components of EPC using UPLC-MS/MS analysis. In addition, we evaluated and validated the mechanism of action of the bioavailable constituents of EPC using network pharmacology analysis. The effects on nitric oxide (NO) and inflammatory cytokines were measured by Griess reagent and enzyme linked immunosorbent assay in lipopolysaccharide (LPS)-induced macrophages. RESULTS In experimental colitis, EPC improved body weight loss, colon length shortening, and disease activity index. Moreover, EPC reduced the serum levels of pro-inflammatory cytokines and histopathological damage to the colon. Network pharmacological analysis identified 13 phytochemicals that were bioavailable following oral administration of EPC, as well as their potential anti-inflammatory effects. 11 identified EPC constituents markedly reduced the overproduction of NO, tumor necrosis factor-α, and/or interleukin-6 in macrophages induced by LPS. The LPS-induced expression of the nuclear factor kappa-light-chain-enhancer of activated B cells reporter gene was reduced by the 4 EPC constituents. CONCLUSIONS The results indicate that the protective activity of EPC against colitis is a result of the additive effects of each constituent on the expression of inflammatory cytokines. Therefore, it suggests that 11 bioavailable phytochemicals of EPC could aid in the management of intestinal inflammation, and also provides useful insights into the clinical application of PC for the treatment of inflammatory bowel diseases.

Abstract
With the emergence of high-throughput technologies, computational screening based on gene expression profiles has become one of the most effective methods for drug discovery. More importantly, profile-based approaches remarkably enhance novel drug-disease pair discovery without relying on drug- or disease-specific prior knowledge, which has been widely used in modern medicine. However, profile-based systematic screening of active ingredients of traditional Chinese medicine (TCM) has been scarcely performed due to inadequate pharmacotranscriptomic data. Here, we develop the largest-to-date online TCM active ingredients-based pharmacotranscriptomic platform integrated traditional Chinese medicine (ITCM) for the effective screening of active ingredients. First, we performed unified high-throughput experiments and constructed the largest data repository of 496 representative active ingredients, which was five times larger than the previous one built by our team. The transcriptome-based multi-scale analysis was also performed to elucidate their mechanism. Then, we developed six state-of-art signature search methods to screen active ingredients and determine the optimal signature size for all methods. Moreover, we integrated them into a screening strategy, TCM-Query, to identify the potential active ingredients for the special disease. In addition, we also comprehensively collected the TCM-related resource by literature mining. Finally, we applied ITCM to an active ingredient bavachinin, and two diseases, including prostate cancer and COVID-19, to demonstrate the power of drug discovery. ITCM was aimed to comprehensively explore the active ingredients of TCM and boost studies of pharmacological action and drug discovery. ITCM is available at http://itcm.biotcm.net.

Abstract
BACKGROUND In recent decades, the prevalence of asthma has substantially increased worldwide. Advances in phytochemistry and phytopharmacology have clarified the active ingredients and biological activities of medicinal plant products for treating asthma, and the role of herbal therapies in asthma treatment has become increasingly evident. However, most plant extracts have low solubility and poor stability of bioactive components, resulting in low bioavailability and loss of efficacy. Owing to these shortcomings, the clinical use of many herbal extracts is limited. OBJECTIVE To summarise and analyse the characteristics of herbal nanoformulations and their application in asthma treatment. The objective of this review article is to address the emerging trends of herbal nanoformulations for an effective treatment for asthma. METHODS Various research and review articles from reputed international journals were referred and compiled. RESULTS The nano-sized herbal formulations improve the solubility and bioavailability of herbal medicines and contribute to the sustained release of drugs, thus, increasing the therapeutic applications of herbal extracts. The review present different types of herbal nanoformulations, including micelles, nanoparticles, solid lipid nanoparticles, lipid-based liquid crystalline nanoparticles and nanoemulsions, which are potential nanodrugs for asthma treatment. CONCLUSIONS Herbal nanoformulations have shown great prospects for treatment of asthma in recent years. More safety and toxicity data are still needed to promote their development and application.

Abstract
BACKGROUND Flavonoids have been demonstrated to have the ability of sensitizing cancer cells to chemotherapy and inverse multidrug resistance via various mechanisms, such as modulating of pumps. The therapeutic effect of candidone, tephrosin, and bavachinin in treatment of cancer, particularly to overcome multidrug resistance (MDR) is largely unknown. The capacity of these agents in sensitization of MDR cells is investigated in the current work. METHODS AND RESULTS We analyzed the impact of candidone, tephrosin, and bavachinin, as chemosensitizer on cell cytotoxicity, P-gp and ABCG2 mRNA expression level on two multidrug resistant cells, ABCG2 overexpressing human epithelial breast cancer cell line (MCF7/MX), and P-gp overexpressing human gastric adenocarcinoma cell line (EPG85.257RDB). The inhibitory concentration of 50% (IC50) of daunorubicin in EPG85.257RDB cells in combination with IC10 of Bavachinin, Tephrosin, and Candidone were 6159 ± 948, 4186 ± 665, 730 ± 258 nM, and this data in MCF7/MX cell were 1773 ± 534, 7160 ± 405 and 3340 ± 622 nM respectively. These three flavonoids dose-dependently decreased the viability of MCF7/MX and EPG85.257RDB and significantly (p < 0.05) decreased IC50 of daunorubicin and mitoxantrone except Tephrosin in MCF7/MX cells. Candidone and Bavachinin were the most potent chemosensitizer in EPG85.257RDB and MCF7/MX cells respectively. Flavonoids did not reduce mRNA expression of P-gp and ABCG2 after 72 h treatment, except Candidone in EPG85.257RDB and Bavachinin in MCF7/MX cells. CONCLUSIONS This effect is not time-dependent, and flavonoids have their own patterns that are cell-dependent. In general, tephrosin, candidone, and bavachinin had the potential of sensitizing MDR cells to mitoxantrone and daunorubicin.

Abstract
BACKGROUND COVID-19 is still causing victims with long-term health consequences, mass deaths, and collapsing healthcare systems around the world. The disease has no efficient drugs. However, previous studies revealed that SARS-CoV-2 and SARS-CoV have 96% and 86.5% similarities in cysteine proteases (3CLpro) and papain-like protease (PLpro) sequences, respectively. This resemblance could be significant in the search for drug candidates with antiviral effects against SARS-CoV-2. OBJECTIVE This paper is a compilation of natural products that inhibit SARS-CoV 3CLpro and PLpro and, concomitantly, reduce inflammation and/or modulate the immune system as a perspective strategy for COVID-19 drug discovery. It also presents in silico studies performed on these selected natural products using SARS-CoV-2 3CLpro and PLpro as targets to propose a list of hit compounds. METHOD The plant metabolites were selected in the literature based on their biological activities on SARS-CoV proteins, inflammatory mediators, and immune response. The consensus docking analysis was performed using four different packages. RESULTS Seventy-nine compounds reported in the literature with inhibitory effects on SARS-CoV proteins were reported as anti-inflammatory agents. Fourteen of them showed in previous studies immunomodulatory effects. Five and six of these compounds showed significant in silico consensus as drug candidates that can inhibit PLpro and 3CLpro, respectively. Our findings corroborated recent results reported on anti-SARS-CoV-2 in the literature. CONCLUSION This study revealed that amentoflavone, rubranoside B, savinin, psoralidin, hirsutenone, and papyriflavonol A are good drug candidate for the search of antibiotics against COVID-19.

Abstract
Lung cancer is grouped into small cell lung cancer (SCLC) and non-SCLC (NSCLC). SCLC exhibits a poor prognosis, and the current anticancer treatment remains unsatisfactory. Bavachinin, present in the seed of Psoralea corylifolia, shows anti-inflammatory effects, immune modulation, and anticancer potency. This study aims to investigate the antitumor effect of bavachinin on SCLC and its underlying mechanism. The SCLC cell line H1688 was treated with different concentrations of bavachinin and showed decreased viability with arrested G2/M and sub-G1 phase cell accumulation at a concentration as low as 25 μM. Expression levels of caspase-3, -8, and -9, as well as Fas, FasL, and Bax, increased with the concentration of bavachinin. The accumulated sub-G1 cells and annexin V confirmed increasing apoptotic cancer cells after treatment. The accumulated G2/M phase cells with increasing levels of phosphorylated CDC25C, CDC2, ATM/ATR, and CHK2/CHK1 confirmed the arrested cell cycle caused by bavachinin via a dose-dependent manner. This phenomenon can be reversed by an ATM/ATR inhibitor, caffeine. Following the administration of bavachinin to xenograft mice with SCLC, the tumor burden decreased without impairing hematologic or hepatorenal functions. Bavachinin induces SCLC apoptosis via intrinsic and extrinsic pathways and causes cancer cell cycle arrest via the ATM/ATR signaling pathway.

Abstract
Steroids are the main drugs currently used to treat asthma. However, the toxic and side effects of these drugs and the tolerance of the drugs due to long-term administration are still problems in the clinical treatment of asthma. Bavachinin has a good effect in the treatment of mouse asthma models, and it can effectively inhibit the expression of a variety of cytokines. However, it is extremely difficult to dissolve in water, has low bioavailability, and is quickly cleared in the blood. These characteristics limit its clinical application potential. In this study, nanotechnology was used to construct an effective oral drug delivery system. Through analysis of serum-related antibodies and cytokines, the system showed significant therapeutic effects on asthma-positive groups. Far-infrared imaging results showed that the system has a good targeted enrichment effect on pathological parts, while showing lower toxicity and higher therapeutic effect. Whether it is the splenocyte flow typing or the analysis of lung tissue, the system has verified the excellent treatment, and through the observation of paraffin sections of lung tissue, it was found that the bronchial morphology returned to normal after drug treatment, and the leakage of inflammatory cells was significantly reduced.

Abstract
Rapid progress in molecular cancer biology coupled with the discovery of novel oncology drugs has opened new horizons for cancer target discovery. As one of the crucial signaling pathways related to tumorigenesis, hypoxia-inducible factor-1 (HIF-1) coordinates the activity of many transcription factors and their downstream molecules that impact tumor growth and metastasis. Accumulating evidence suggests that the transcriptional responses to acute hypoxia are mainly attributable to HIF-1α. Moreover, the overexpression of HIF-1α in several solid cancers has been found to be strongly associated with poor prognosis. Thus, pharmacological targeting of the HIF-1 signaling pathways has been considered as a new strategy for cancer therapy in the recent years. Although over the past decade, tremendous efforts have been made in preclinical studies to develop new HIF-1 inhibitors from natural products (reservoirs of novel therapeutic agents), to date, these efforts have not been successfully translated into clinically available treatments. In this review, we provide new insights into the bio-pharmacological considerations for selecting natural compounds as potential HIF-1 inhibitors to accelerate anti-cancer drug development. In addition, we highlighted the importance of assessing the dependency of cancer on HIF1A to shortlist cancer types as suitable disease models. This may subsequently lead to new paradigms for discovering more HIF-1 inhibitors derived from natural products and facilitate the development of potent therapeutic agents targeting specific cancer types.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a progressive and chronic liver disease. No effective drug is currently approved for the treatment of NAFLD. Traditionally it is thought that pathogenesis of NAFLD develops from some imbalance in lipid control, thereby leading to hepatotoxicity and disease development. Squalene synthase (SQS), encoded by FDFT1, is a key regulator in cholesterol synthesis and thus a potential target for the treatment of NAFLD. Here we could identify bavachinin, a component from traditional Chinese medicine Fructus Psoraleae (FP), which apparently protects HepaRG cells from palmitic acid induced death, suppressing lipid accumulation and cholesterol synthesis through inhibition of FDFT1 through the AKT/mTOR/SREBP-2 pathway. Over-expression of FDFT1 abolished bavachinin (BVC) -induced inhibition of cholesterol synthesis. The data presented here suggest that bavachinin acts as a cholesterol synthesis enzyme inhibitor, and might serve as a drug for treating NAFLD in the future.

Enhancing the Therapeutic Efficacy of Daunorubicin and Mitoxantrone with Bavachinin, Candidone, and Tephrosin. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:3291737. [PMID: 31814840 PMCID: PMC6877970 DOI: 10.1155/2019/3291737] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/18/2019] [Accepted: 08/20/2019] [Indexed: 12/20/2022]
Abstract
The capability of flavonoids in sensitizing cancer cells was demonstrated in numerous works to chemotherapy and converse multidrug resistance by modulating efflux pumps and apoptosis mechanisms. Three flavonoids, namely, bavachinin, tephrosin, and candidone, have been recently introduced to cancer treatment research presenting various activities, such as antibacterial, immunomodulatory, cell death, and anticancer. Less information exists regarding the therapeutic significance of these flavonoids in cancer treatment, especially in overcoming multidrug resistance (MDR). Here, we tempted to investigate the potency of these agents in reversing MDR by analyzing their effects as chemosensitizers on cell cytotoxicity, P-gp and ABCG2 protein expression levels, and their function on two multidrug-resistant cell lines, P-gp-overexpressing human gastric adenocarcinoma cell line (EPG85.257RDB) and ABCG2-overexpressing human epithelial breast cancer cell line (MCF7/MX). The inhibitory concentration of 10% (IC10) of bavachinin, tephrosin, and candidone in EPG85.257RDB cells was 1588.7 ± 202.2, 264.8 ± 86.15, and 1338.6 ± 114.11 nM, respectively. Moreover, these values in MCF7/MX cell were 2406.4 ± 257.63, 38.8 ± 4.28, and 27.9 ± 5.59 nM, respectively. Expression levels of ABCG2 and P-gp were not significantly downregulated by these flavonoids. Maximum levels of daunorubicin and mitoxantrone accumulations and minimum rates of drug efflux in both cell lines were detected 48 hrs posttreatment with tephrosin and bavachinin, respectively. Chemosensitization to mitoxantrone and daunorubicin treatments was, respectively, achieved in MCF7/MX and EPG85.257RDB cells in response to IC10 of bavachinin and tephrosin, independently. These effects did not follow time-dependent manner, and each flavonoid had its cell-dependent patterns. Overall, bavachinin, tephrosin, and candidone showed potency to sensitize MDR cells to daunorubicin and mitoxantrone and could be considered as attractive MDR modulators for cancer treatment. However, their action was time and cell specific.

Abstract
Drug-induced liver injury is one of the main causes of drug non-approval and drug withdrawal by the Food and Drug Administration (FDA). Bavachinin (BVC) is a natural product derived from the fruit of the traditional Chinese herb Fructus Psoraleae (FP). There have been reports of acute liver injury following the administration of FP and its related proprietary medicines. To explore BVC hepatotoxicity and its mechanisms, we used the HepaRG cell line. In our recent research, we showed that BVC induces HepaRG cell death, mainly via BVC-induced oxidative damage. The formation of ROS is closely related to the activation of the stress-activated kinases, JNK and p38, while SP600125 (SP, JNK inhibitor) and SB203580 (SB, p38 inhibitor) pretreatment inhibited the generation of ROS. On the other hand, N-acetylcysteine (NAC) pretreatment prevented the phosphorylation of p38 but not that of JNK. Taken together, these data reveal that BVC induces HepaRG cell death via ROS and the JNK/p38 signaling pathways.

Abstract
Asthma is one of the most common chronic inflammatory disorders, associated with reversible airflow obstruction, airway hyperresponsiveness, and airway remodeling. This disease has a significant impact on individuals, their families, and society. Standardized therapeutics such as inhaled corticosteroid in combination with long acting β2 agonist have been applied for asthma control; however, complementary and alternative medicines, especially herbal medicines, are still widely used all over the world. A growing body of literature suggests that various herbals or related products might be effective in inhibiting asthmatic inflammation. In this review, we summarize recent advances about the mechanistic studies of herbal medicines on allergic airway inflammation in animal models and their potential application into clinic for asthma control.

Abstract
Paeoniflorin (PF), one of the major active ingredients of Chinese peony, has demonstrated anti-inflammatory and immunoregulatory effects. However, it has remained unclear whether PF treatment can inhibit allergic inflammation in asthma. In this study, we evaluated the effects of PF on pulmonary function and airway inflammation in asthmatic mice. The allergic asthma models were established in BALB/c mice. The mice were sensitized and challenged with ovalbumin. Airway hyperresponsiveness was detected by direct airway resistance analysis. Lung tissues were examined for inflammatory cell infiltration. IL-5, IL-13, IL-17, and eotaxin in bronchoalveolar lavage fluid (BALF) and their mRNA expression in lung tissue were examined by ELISA and realtime PCR, respectively. The total IgE level in serum was measured by ELISA. The protein expression of p-ERK and p-JNK was detected by western blot. Our data showed that PF oral administration significantly reduced airway hyperresponsiveness to aerosolized methacholine and decreased IL-5, IL-13, IL-17 and eotaxin levels in the BALF, and decreased IgE level in the serum. Histological studies showed that PF administration markedly decreased inflammatory infiltration. Similarly, treatment with PF significantly inhibited IL-5, IL-13, IL-17 and eotaxin mRNA expression in lung tissues. The protein expression levels of p-ERK and p-JNK were substantially decreased after oral administration of PF. In summary, PF displayed anti-inflammatory effects in the OVA-induced asthmatic model by decreasing the expression of IL-5, IL-13, IL-17 and eotaxin. These effects were mediated at least partially by inhibiting the activation of MAPK pathway.

Abstract
Initially identified as an occasional and peculiar mode of gene regulation in eukaryotes, RNA-binding protein-mediated post-transcriptional control of gene expression has emerged, over the last two decades, as a major contributor in the control of gene expression. A large variety of RNA-binding proteins (RBPs) allows the recognition of very diverse messenger RNA sequences and participates in the regulation of basically all cellular processes. Nevertheless, the rapid outcome of post-transcriptional regulations on the level of gene expression has favored the expansion of this type of regulation in cellular processes prone to rapid and frequent modulations such as the control of the inflammatory response. At the molecular level, the 3'untranslated region (3'UTR) of mRNA is a favored site of RBP recruitment. RBPs binding to these regions control gene expression through two major modes of regulation, namely mRNA decay and modulation of translational activity. Recent progresses suggest that these two mechanisms are often interdependent and might result one from the other. Therefore, different RBPs binding distinct RNA subsets could share similar modes of action at the molecular level. RBPs are frequent targets of post-translational modifications, thereby disclosing numerous possibilities for pharmacological interventions. However, redundancies of the transduction pathways controlling these modifications have limited the perspectives to define RBPs as new therapeutic targets. Through the analysis of several examples of RBPs binding to 3'untranslated region of mRNA, we present here recent progress and perspectives regarding this rapidly evolving field of molecular biology.

Effect of Bavachinin and its derivatives on T cell differentiation. Int Immunopharmacol 2014; 19:399-404.

Abstract
Bavachinin, which can be isolated from the Chinese herb Fructus Psoraleae, has the potential as a potent anti-asthma drug. However, the extremely low water solubility of Bavachinin limits its application. In this study, two new derivatives of Bavachinin, i.e., compounds A and B, whose water solubility is better than that of Bavachinin, were synthesized via biotransformation. A comparative investigation was then performed on the effects of these two new derivatives, along with Bavachinin, on T cell differentiation. The results showed that they have different effects. Bavachinin and compound B inhibited green fluorescent protein (GFP) production from the T cells of IL-4-GFP-enhanced transcript (4GET) mice, whereas compound A did not. The effect was mainly attributed to the inhibition of GATA-3 protein production. Bavachinin and compound B can inhibit the production of GATA-3 mRNA, but they showed different effects on the production of T-bet mRNA. Compound B increased the production of T-bet mRNA, whereas Bavachinin did not. The results will be very useful for optimizing Bavachinin so that potent anti-allergic drugs can be developed. The structure-activity relationship of Th2 was revealed based on the difference between Bavachinin and compound B. This finding can enrich the database of preliminary drug screening from their chemical structures.
