[PMID: 37795938 DOI: 10.1002/bio.4605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 09/12/2023] [Accepted: 10/01/2023] [Indexed: 10/06/2023]
Abstract
Some ingredients from herbal medicine can significantly affect the activity of CYP2D6, thus leading to serious interactions between herbs and drugs. Quercetin and hyperoside are active ingredients widely found in vegetables, fruits, and herbal medicines. Quercetin and hyperoside have many biological activities. In this work, the characteristic bindings of CYP2D6 with quercetin/hyperoside are revealed by multi-spectroscopy analysis, molecular docking, and molecular dynamics simulations. The fluorescence of CYP2D6 is statically quenched by quercetin and hyperoside. The binding constant (Ka ) values of CYP2D6-quercetin/hyperoside range from 104 L mol-1 , which indicates that these two flavonoids bind moderately to CYP2D6. Meanwhile, quercetin has a stronger quenching ability to CYP2D6 than that of hyperoside. The secondary structure of CYP2D6 is obviously changed by binding with quercetin/hyperoside. The docking results reveal that the quercetin/hyperoside enters the active site of CYP2D6 near heme and binds to CYP2D6 by hydrogen bonds and van der Waals forces. The molecular dynamics simulation results indicate that the binding of quercetin/hyperoside can stabilize the two complexes, enhance the flexibility of CYP2D6 backbone atoms, and make a more unfolded and looser structure of CYP2D6.

Ginsenoside Rb 1 for overcoming cisplatin-insensitivity of A549/DDP cells in vitro and vivo through the dual-inhibition on two efflux pumps of ABCB1 and PTCH1. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 115:154776. [PMID: 37087793 DOI: 10.1016/j.phymed.2023.154776] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/24/2023] [Accepted: 03/16/2023] [Indexed: 05/03/2023]
Abstract
BACKGROUND The multi-drug resistance is an inherent weakness in the chemotherapeutics of non-small cell lung cancer occurring frequently all over the world. Clinically, ginseng and Chinese medicinal prescriptions including ginseng usually used as anti-tumor adjuncts due to its characteristic of qi-invigorating, which could improve the curative effect of chemotherapy drugs and reduce their toxic side effects. Triterpenoid saponins are the crucial active ingredients in Panax ginseng, and Ginsenoside Rb1 is of the highest quantities. However, the research on the tumor drug-resistance reversal effect and mechanism of ginsenoside Rb1 is still not clear. PURPOSE This study aimed to systematically estimate the reversal activity of Ginsenoside Rb1 on cisplatin-insensitivity of A549/DDP cells and to reveal its prospective molecular mechanism. METHODS MTT assay were conducted to evaluate the reversal activity on cisplatin-insensitivity of A549/DDP cells of Ginsenoside Rb1in vitro, and the behavior was also studied by establishing a subcutaneous transplanted tumor model of A549/DDP in BALB/c-nu mice. In addition, P-gp ATPase activity assay, cisplatin accumulation assay, Annexin V-FITC apoptosis assay, real-time qPCR analysis and western blotting analysis were used to clarify the potential mechanism. RESULTS Ginsenoside Rb1 could effectively reverse the cisplatin-resistance of A549/DDP in vitro and vivo. And after the co-treatment of Ginsenoside Rb1 plus cisplatin, the accumulation of cisplatin increased in A549/DDP cells, which was accompanied with the down-regulation of the mRNA and protein expression levels of ABCB1, SHH, PTCH1 and GLI2. Besides, the apoptosis-inducing ability of cisplatin improved by the relative regulation on the protein expression level of Bax and Bcl-2. Far more importantly, the changes of CYP3A4 mRNA and protein levels were not significant. CONCLUSION Ginsenoside Rb1 could increase the concentration of intracellular cisplatin and improve the insensitivity for cisplatin on A549/DDP cells. Even better, there was perhaps no unpredictable CYP3A4-mediated pharmacokinetic interactions after the combination of Ginsenoside Rb1 plus cisplatin. Ginsenoside Rb1 was a probable reversal agent for the cisplatin-insensitivity of A549/DDP cells, with a bifunction of inhibiting the efflux of two drug pumps (P-gp and PTCH1) by targeting ABCB1 and Hedgehog (Hh) pathway. In general, this research laid the groundwork for the development of a new reversal agent for the cisplatin-insensitivity of NSCLC.

Abstract
Spinosin, a natural flavone-C-glycoside that is mainly isolated from the seeds of Ziziphus jujuba Mill. var. spinosa. It exerts the effects to ameliorate the neurological disorders, such as hypnosis effects, improvement of cognitive function, sedation effects, and anxiolytic effects, as well as anti-melanogenic effect, cardioprotective effects, and anti-cancer activity. However, the insufficient basic research, unclear mechanisms, and poor bioavailability may limit the prospects of spinosin in clinical utilization. In this review, we comprehensively summarized the latest information on the pharmacology, pharmacokinetics, toxicity, and NMR characteristic of spinosin, to evaluate its potential therapeutic for clinical application, hoping to provide some rational perspective for the innovative agent development and usage of spinosin in future.

Abstract
A strategy to synthesize water-soluble and fluorescent flavonoid-silica nanocomposites (FSiNCs) simultaneously featuring anti-tumor and anti-bacterial abilities is developed. Furthermore, it is demonstrated that the therapeutic effects of FSiNCs are associated with the selective accumulation of reactive oxide species in both tumor and bacteria cells. Following that, the resultant FSiNCs are incorporated with thrombin and fibrinogen, being sprayed onto the tumor surgical wound site to in situ form fibrin gel (FSiNCs@Fibrin). Remarkably, such FSiNCs@Fibrin results in an ≈18-fold reduction in intratumoral bacteria numbers and ≈12-fold decrease in tumor regrowth compared to equivalent free flavonoid-loaded gel.

Abstract
The inhibitory effects of engeletin on the activities of human cytochrome P450 3A4 and 2D6 (CYP3A4 and CYP2D6) were investigated by enzyme kinetics, multi-spectroscopy and molecular docking. Engeletin was found to strongly inhibit CYP3A4 and CYP2D6, with the IC50 of 1.32 μM and 2.87 μM, respectively. The inhibition modes of engeletin against CYP3A4 and CYP2D6 were a competitive type and a mixed type, respectively. The fluorescence of the two CYPs was quenched statically by engeletin, which was bound to CYP3A4 stronger than to CYP2D6 at the same temperature. Circular dichroism spectroscopy, three-dimensional fluorescence, ultraviolet-visible spectroscopy and synchronous fluorescence confirmed that the conformation and micro-environment of the two CYPs protein were changed after binding with engeletin. Molecular docking, ultraviolet-visible spectroscopy and the fluorescence data revealed that engeletin had strong binding affinity to the two CYPs through hydrogen and van der Waals forces. The findings here suggested that engeletin may cause the herb-drug interactions for its inhibition of CYP3A4 and CYP2D6 activities.

Abstract
Molecular modeling in pharmacology is a promising emerging tool for exploring drug interactions with cellular components. Recent advances in molecular simulations, big data analysis, and artificial intelligence (AI) have opened new opportunities for rationalizing drug interactions with their pharmacological targets. Despite the obvious utility and increasing impact of computational approaches, their development is not progressing at the same speed in different fields of pharmacology. Here, we review current in silico techniques used in cardiovascular diseases (CVDs), cardiological drug discovery, and assessment of cardiotoxicity. In silico techniques are paving the way to a new era in cardiovascular medicine, but their use somewhat lags behind that in other fields.

Abstract
The presented study investigates the effects of morin against toxicity induced by acrylamide (ACR) in the brains of Sprague Dawley rats. In this study, neurotoxicity was induced by orally administering 38.27 mg/kg/b.w ACR to rats through gastric gavage for 10 days. Morin was administered at the same time and at different doses (50 and 100 mg/kg/b.w) with ACR. Biochemical and Western blot analyses showed that ACR increased malondialdehyde (MDA), p38α mitogen-activated protein kinase (p38α MAPK), nuclear factor kappa-B (NF-κB), tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), cyclooxygenase-2 (COX-2), p53, caspase-3, bcl-2 associated X protein (Bax), Beclin-1, light chain 3A (LC3A), and light chain 3B (LC3B) levels and decreased those of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH), b-cell lymphoma-2 (Bcl-2), mammalian target of rapamycin (mTOR), phosphoinositide 3-kinase (PI3K), and protein kinase B (Akt) in brain tissue and therefore induced neurotoxicity by causing oxidative stress, inflammation, apoptosis, and autophagy. On the other hand, it was determined that morin positively affected the levels of these markers by displaying antioxidant, anti-inflammatory, anti-apoptotic, and anti-autophagic properties and had a protective effect on ACR-induced neurotoxicity. As a result, morin is an effective substance against brain damage caused by ACR, yet further studies are needed to use it effectively.

Abstract
Astilbin, isoastilbin and neoastilbin are the three flavonoid isomers prevalent in Rhizoma Smilax glabra. The interactions between human cytochrome P450 2D6 (CYP2D6) and the three isomers were investigated by multiple spectroscopic coupled with molecular docking. As a result, the fluorescence intensity of CYP2D6 was quenched statically by the three isomers. Meanwhile, astilbin had the strongest binding ability to CYP2D6, followed by isoastilbin and neoastilbin under the identical temperature. Synchronous fluorescence, three-dimensional fluorescence, ultraviolet-visible spectroscopy, circular dichroism and Fourier-transform infrared spectra confirmed that the conformation and micro-environment of CYP2D6 protein were changed after binding with the three isomers. As suggested from molecular docking, the three isomers had strong binding affinity to CYP2D6 via the bonding of hydrogen and van der Waals forces, and the results were in agreement with the fluorescence results. The findings here suggested that astilbin, isoastilbin and neoastilbin may cause the herb-drug interactions for their inhibition of CYP2D6 activity.

Abstract
Astilbin, neoastilbin and isoastilbin are three flavonoid isomers from Smilacis glabrae Roxb. (S. glabrae). Several studies have shown that consumption of flavonoids can increase the risk of food/drug-drug interaction by affecting the activities of human cytochrome CYP3A4 and 2D6. In the present study, an ultrahigh-performance liquid chromatography and triple quadrupole mass spectrometry method was developed for the determination of the interaction between three flavonoid isomers and two CYPs. Under the optimized reaction conditions, the Km values were 18.9 and 36.4 μM and the Vmax values were 0.02 and 0.20 μM/min for CYP3A4 and 2D6 in vitro, respectively. Astilbin showed the strongest inhibition on CYP3A4, followed by isoastilbin and neoastilbin with IC50 values of 2.63, 3.03 and 6.51 μM. Neoastilbin showed the strongest inhibition on CYP2D6, followed by isoastilbin and astilbin, with IC50 values of 1.48, 11.87 and 14.16 μM, respectively. The three isomers showed reversible inhibition on both enzymes. Neoastilbin and astilbin were noncompetitive type for CYP3A4 and 2D6, isoastilbin was a mixture and noncompetitive type for CYP3A4 and 2D6, respectively. Our study suggests that the three isomers may increase the risk of food/drug-drug interactions by affecting the activities of CYP3A4 and 2D6.
