Characterization of inhibitory effects of perfluorooctane sulfonate on human hepatic cytochrome P450 isoenzymes: Focusing on CYP2A6

Perfluorooctane sulfonate (PFOS) is a chemically stable compound extensively used as oil and water repellent, surface active agents in our daily life. Accumulative research evidence gradually appears the toxicity of PFOS against mammals, but the whole figure remains to be elucidated. The present study was conducted to know the effects of PFOS on human hepatic drug metabolizing-type cytochrome P450 (CYP) isoenzymes such as CYP1A2 (7-ethoxyresorufin as a substrate), CYP2A6 (coumarin), CYP2B6 (7-ethoxy-4-trifluoromethylcoumarin), CYP2C8 (paclitaxel), CYP2C9 (diclofenac), CYP2C19 (S-mephenytoin), CYP2D6 (bufuralol), CYP2E1 (chlorzoxazone) and CYP3A4 (testosterone) in human livers employing their typical substrates. Although all of the oxidation reactions tested were more or less inhibited by PFOS, diclofenac 4?-hydroxylation mediated mainly by CYP2C9 was most strongly inhibited (Ki value of 40 nM), followed by paclitaxel 6alpha-hydroxylation mediated mainly by CYP2C8 (Ki value of 4 muM). The substrate oxidation reactions catalyzed by CYP2A6, CYP2B6, CYP2C19 and CYP3A4 were moderately (Ki values of 35 to 45 muM), and those by CYP1A2, CYP2D6 and CYP2E1 were weakly inhibited by PFOS (Ki values of 190-300 muM). The inhibition by PFOS for coumarin 7-hydroxylation mainly catalyzed by human liver microsomal CYP2A6 as well as by the recombinant enzyme was found to be enhanced by the preincubation of PFOS with human liver microsomes and NADPH as compared to the case without preincubation. The inhibition of the human liver microsomal cumarin 7-hydroxylation was PFOS concentration-dependent, and exhibited pseudo-first-order kinetics with respect to preincubation time, yielding Kinact and KI values of 0.06 min-1 and 23 muM, respectively. These results suggest that the metabolism of medicines which are substrates for CYP2C9 may be altered by PFOS in human bodies, and that PFOS is a mechanism-based inhibitor of CYP2A6.

Discovery and characterization of aminopiperidinecoumarin melanin concentrating hormone receptor 1 antagonists

4-(1-Benzo[1,3]dioxol-5-ylmethylpiperidine-4-ylmethyl)-6-chlorochromen-2- one (7) is a potent, orally bioavailable melanin concentrating hormone receptor 1 (MCHr1) antagonist that causes dose-dependent weight loss in diet-induced obese mice. Further evaluation of 7 in an anesthetized dog model of cardiovascular safety revealed adverse hemodynamic effects at a plasma concentration comparable to the minimally effective therapeutic concentration. These results highlight the need for scrutiny of the cardiovascular safety profile of MCHr1 antagonists.

Monolithic silica rod liquid chromatography with ultraviolet or fluorescence detection for metabolite analysis of cytochrome P450 marker reactions

In vitro cytochrome P450 assays are used in metabolism studies in support of early phases of drug discovery to investigate, e.g., metabolic stability, enzyme inhibition and induction by new chemical entities. LC-UV and LC-fluorescence are traditional analytical tools in support of such studies. However, these tools typically comprise different methods of relatively low throughput for the various metabolites of probe reactions. In recent years, LC-MS methods have been developed to increase throughput. Increased throughput can also be achieved by means of modern chromatographic tools in combination with UV and fluorescence detection. This approach is especially suitable when cytochrome P450 isoforms are investigated by means of single probe incubations. Here, an LC-UV/fluorescence system based on a monolithic porous silica column is described for the analysis of metabolites of nine cytochrome P450 marker reactions [phenacetin to paracetamol (CYP1A2), coumarin to 7-hydroxycoumarin (CYP2A6), paclitaxel to 6alpha-hydroxypaclitaxel (CYP2C8), diclofenac to 4-hydroxydiclofenac (CYP2C9), mephenytoin to 4-hydroxymephenytoin (CYP2C19), bufuralol to 1-hydroxybufuralol (CYP2D6), chlorzoxazone to 6-hydroxychlorzoxazone (CYP2E1), midazolam to 1-hydroxymidazolam (CYP3A4), and testosteron to 6beta-hydroxytestosteron (CYP3A4)]. While offering sensitivities and linear ranges comparable to previously reported methods, the set-up described here provides ease of use and increased throughput with maximum cycle times of 4.5 min.

Isocyanide-based cascade reactions in the synthesis of aza-heterocycles: A marriage of convenience

Background: The design and performing of cascade reactions is a challenging but stimulating and interesting facet of organic synthesis, yet one that can convey conspicuous novelty, efficiency as well as elegance and sophistication to synthetic approaches. On the other hand, isocyanides are well-recognized as privileged synthons in the synthesis of a wide range of heterocycles. Objective: In this review, we try to illustrate the power, efficiency, and convenience of combining cascade process as an expedient strategy with versatility of isocyanide-based multicomponent reactions in the synthesis of aza-heterocycles from 1993 till date. Comprising isocyanides in cascade or sequential pathway also represents a milestone in combinatorial chemistry which is a bounce for this contented marriage.

Characterization of novel cytochrome P450 2E1 knockout rat model generated by CRISPR/Cas9

A bacterial CRISPR-associated protein-9 nuclease (CRISPR/Cas9) from Streptococcus pyogenes has generated considerable excitement as a new tool to edit the targeted genome. Cytochrome P450 (CYP) 2E1 not only plays an important role in the xenobiotic metabolism and chemical toxicity, but also is involved in many kinds of diseases, such as alcoholic liver diseases and diabetes. Despite its importance, few animal models are used to predict CYP2E1 properties in physiology, pathology, as well as carcinogen activation. To establish a novel model for investigating the functions of CYP2E1 in vivo, this study has successfully generated the Cyp2e1 knockout (KO) rat model without detectable off-target effects using CRISPR/Cas9 system. The Cyp2e1 KO rats were viable and fertile and did not display any obvious physiological abnormities. The absent expression of CYP2E1 in KO rats also resulted in inactive behaviors in the metabolism of CYP2E1 substrates. The Cyp2e1 KO rats as a novel and available rodent animal model provide a powerful tool for the study of CYP2E1 in the chemical metabolism, toxicity, carcinogenicity, and its core factor in drug-drug interactions.

Synthesis and screening of some novel N-(4-Oxo-2-substituted phenyl- 1,3-thiazolidin-3-Yl)-1,3-benzoxazole-5-carboxamide derivatives for antibacterial and antitubercular activities

A novel series of N-(4-oxo-2-substituted phenyl-1,3-thiazolidin-3-yl)-1,3-benzoxazole-5-carboxamide III (a-h) derivatives were synthesized by the reaction between Schiff bases of benzoxazole II (a-h) with thioglycollic acid. The purity of these compounds was confirmed by melting point and TLC. Structure of these compounds was confirmed on the bases of IR, 1H NMR, 13C NMR and Mass spectral data. All the synthesized compounds were screened for their antibacterial and antitubercular activity using broth microdilution method and Microplate Alamar Blue Assay (MABA) method respectively. For antibacterial and antitubercular activities screening ciprofloxacin, norfloxacin and isoniazid were used as standard drugs respectively. The results showed that compounds III c, III d and III f exhibited good antibacterial activity and compounds III c, III f, III g and III h showed good antitubercular activity.
