Inhibiton of cytochrome P450 isoenzymes and P-gp activity by multiple extracts of Huang-Lian-Jie-Du decoction

Ethnopharmacological relevance: Huang-Lian-Jie-Du-Decotion (HLJDD), an important traditional Chinese medicine formula, has been used for various diseases in clinical practice, and thus has high potential to induce cytochrome P450 (CYP) isoenzymes/P-glycoprotein (P-gp) mediated herb-drug interactions (HDIs) with other co-administered drugs. The purpose of this study was to investigate the in vitro effects of multiple extracts including aqueous extracts, total flavonoids, iridoids, alkaloids from HLJDD on the activities of CYPs in rats (CYP1A2, CYP2C6, CYP2D2, CYP2E1 and CYP3A1) and P-gp, and then to predict potential interactions with co-administered drugs. Materials and methods: The effects of the four extracts from HLJDD on the CYPs activity were evaluated in rat liver microsomes incubation system, and then determined by LC-MS/MS-based CYPs probe substrate assay. Caco-2 cell monolayer was used to investigate the effect of the four extracts on the efflux of Rhodamine 123 to evaluate their influences on P-gp activity. Results: The results show that total flavonoids and alkaloids exibited strong inhibition on rat CYP isoenzymes activities. Total flavonoids exhibited different inhibitory effects on CYPs activities with an order of CYP3A1 > CYP2C6 > CYP2E1 > CYP1A2 > CYP2D2, and the values of IC50 were 4.24, 8.16, 17.56, 19.03, 29.51 mug/mL, respectively. Total alkaloids possessed similar inhibition on CYPs and could strongly inhibit the activity of CYP2D2 (IC50=2.38 mug/mL), CYP3A1 (IC50=2.61 mug/mL), CYP2E1 (IC50=22.35 mug/mL), CYP1A2 (IC50=23.2 mug/mL) and CYP2C6 (IC50=43.09 mug/mL). Moderate degree of inhibition on CYPs activities was observed in aqueous and total iridoids extracts. Results from transport assay revealed that total flavonoids and alkaloids exhibited significant inhibitory effect on P-gp activity as evidenced by strong inhibition on the efflux of Rhodamine-123 with IC50 of 104.6 and 82.6 mug/mL. But aqueous extract showed weak and iridoids had negligible effect on P-gp activity. Conclusions: This study clearly demonstrated that total flavonoids and alkaloids from HLJDD can significantly inhibit the activities of CYPs and P-gp, which should be taken into consideration to predict any potential HDIs when HLJDD and its bioactive components are co-administered with other therapeutic drugs metabolized by CYPs or transported by P-gp.

Oxadiazole Derivatives as Dual Orexin Receptor Antagonists: Synthesis, Structure?Activity Relationships, and Sleep-Promoting Properties in Rats

The orexin system plays an important role in the regulation of wakefulness. Suvorexant, a dual orexin receptor antagonist (DORA) is approved for the treatment of primary insomnia. Herein, we outline our optimization efforts toward a novel DORA. We started our investigation with rac-[3-(5-chloro-benzooxazol-2-ylamino)piperidin-1-yl]-(5-methyl-2-[1,2,3]triazol-2-ylphenyl)methanone (3), a structural hybrid of suvorexant and a piperidine-containing DORA. During the optimization, we resolved liabilities such as chemical instability, CYP3A4 inhibition, and low brain penetration potential. Furthermore, structural modification of the piperidine scaffold was essential to improve potency at the orexin 2 receptor. This work led to the identification of (5-methoxy-4-methyl-2-[1,2,3]triazol-2-ylphenyl)-{(S)-2-[5-(2-trifluoromethoxyphenyl)-[1,2,4]oxadiazol-3-yl]pyrrolidin-1-yl}methanone (51), a potent, brain-penetrating DORA with in vivo efficacy similar to that of suvorexant in rats.

Continuous culture adaptation of methylobacterium extorquens AM1 and TK 0001 to very high methanol concentrations

The bio-economy relies on microbial strains optimized for efficient large scale production of chemicals and fuels from inexpensive and renewable feedstocks under industrial conditions. The reduced one carbon compound methanol, whose production does not involve carbohydrates needed for the feed and food sector, can be used as sole carbon and energy source by methylotrophic bacteria like Methylobacterium extorquens AM1. This strain has already been engineered to produce various commodity and high value chemicals from methanol. The toxic effect of methanol limits its concentration as feedstock to 1% v/v. We obtained M. extorquens chassis strains tolerant to high methanol via adaptive directed evolution using the GM3 technology of automated continuous culture. Turbidostat and conditional medium swap regimes were employed for the parallel evolution of the recently characterized strain TK 0001 and the reference strain AM1 and enabled the isolation of derivatives of both strains capable of stable growth with 10% methanol. The isolates produced more biomass at 1% methanol than the ancestor strains. Genome sequencing identified the gene metY coding for an O-acetyl-L- homoserine sulfhydrylase as common target of mutation. We showed that the wildtype enzyme uses methanol as substrate at elevated concentrations. This side reaction produces methoxine, a toxic homolog of methionine incorporated in polypeptides during translation. All mutated metY alleles isolated from the evolved populations coded for inactive enzymes, designating O-acetyl-L-homoserine sulfhydrylase as a major vector of methanol toxicity. A whole cell transcriptomic analysis revealed that genes coding for chaperones and proteases were upregulated in the evolved cells as compared with the wildtype, suggesting that the cells had to cope with aberrant proteins formed during the adaptation to increasing methanol exposure. In addition, the expression of ribosomal proteins and enzymes related to energy production from methanol like formate dehydrogenases and ATP synthases was boosted in the evolved cells upon a short-term methanol stress. D-lactate production from methanol by adapted cells overexpressing the native D-lactate dehydrogenase was quantified. A significant higher lactate yield was obtained compared with control cells, indicating an enhanced capacity of the cells resistant to high methanol to assimilate this one carbon feedstock more efficiently.

2-sulfinyl benzothiazoles, -oxazoles and -imidazoles are novel in vitro bone anti-reabsorptive compounds

Bone resorption by osteoclasts is dependent on H+ transport into the external resorption lacunae, generating an acidic microenvironment in which bone mineral dissolution and matrix degradation occur. A vacuolar H+-ATPase is responsible for osteoclast H+ secretion. Here, we describe novel vacuolar H+-ATPase inhibitors that inhibit bone resorption in vitro. Several agents inhibited 45Ca release from mouse calvariae, 3H-proline release from bone particles by chicken osteoclast-like cells, and resorption pit formation by murine osteoclasts on dentine slices. One compound, a 2-sulfinylbenzothiazole (XS238), is significantly more potent than previously reported vacuolar H+-ATPase inhibitors, exhibiting an IC50 of 5 muM in the 45Ca release assay, an IC50 of 1 muM in the 3H-proline release assay, and an IC50 of 100 nM in the resorption pit assay. The potent H+-ATPase inhibitors described may have value in treating osteoporosis and other bone diseases.

Effect of Oridonin on Cytochrome P450 Expression and Activities in HepaRG Cell

Oridonin, the major terpene found in Rabdosia rubescens, is widely used as a dietary supplement or therapeutic drug. However, the effects of oridonin on major CYP450s are still unclear. As oridonin can enhance the effect of other clinical drugs, in this study, we investigated the influence of oridonin on CYP450s mRNA expression and its impact on activities in human HepaRG cell to evaluate the safety by studying its potential drug interaction. HepaRG cells were cultured with series concentrations of oridonin (1, 5, 10, and 20 mumol/L), and the major CYP450s mRNA and protein expression, as well as enzyme activities were analyzed by real-time polymerase chain reaction, Western blot analysis and UPLC-MS/MS-based metabolite assay. In general, ordonin has induced effects on the major member of CYP450s mRNA and protein expression, as well as on the enzyme activity in human HepaRG cells, especially on CYP3A4 and CYP2C9. To our knowledge, this is the first systematic research about the inductive effects of oridonin on the major member of CYP450s in human cell line. These results may provide at least partly of the basis for potential drug-drug interactions and oridonin should be used with caution to avoid potential risk.
