Assessment of inhibition of bovine hepatic cytochrome P450 by 43 commercial bovine medicines using a combination of in vitro assays and pharmacokinetic data from the literature

Background: There has been a lack of information about the inhibition of bovine medicines on bovine hepatic CYP450 at their commercial doses and dosing routes. Objective: The aim of this work was to assess the inhibition of 43 bovine medicines on bovine hepatic CYP450 using a combination of in vitro assay and Cmax values from pharmacokinetic studies with their commercial doses and dosing routes in the literature. Methods: Those drugs were first evaluated through a single point inhibitory assay at 3 muM in bovine liver microsomes for six specific CYP450 metabolisms, phenacetin o-deethylation, coumarin 7-hydroxylation, tolbutamide 4-hydroxylation, bufuralol 1-hydroxylation, chlorzoxazone 6-hydroxylation and midazolam 1?-hydroxylation. When the inhibition was greater than 20% in the assay, IC50 values were then determined. The potential in vivo bovine hepatic CYP450 inhibition by those drugs was assessed using a combination of the IC50 values and in vivo Cmax values from pharmacokinetic studies at their commercial doses and administration routes in the literature. Results: Fifteen bovine medicines or metabolites showed in vitro inhibition on one or more bovine hepatic CYP450 metabolisms with different IC50 values. Desfuroylceftiour (active metabolite of ceftio-fur), nitroxinil and flunixin have the potential to inhibit one of the bovine hepatic CYP450 isoforms in vivo at their commercial doses and administration routes. The rest of the bovine medicines had low risks of in vivo bovine hepatic CYP450 inhibition. Conclusion: This combination of in vitro assay and in vivo Cmax data provides a good approach to assess the inhibition of bovine medicines on bovine hepatic CYP450.

Selective synthesis of 2-aminobenzoxazoles and 2-mercaptobenzoxazoles by using o-aminophenols as starting material

2-Aminobenzoxazoles and 2-mercaptobenzoxazoles were selectively synthesized by treating o-aminophenols with dithiocarbamates and tetramethylthiuram disulfide (TMTD), respectively. With the promotion of NaH/CuI, the reaction of o-aminophenols with dithiocarbamates gave 2-aminobenzoxazoles with good yield (70?92%) in one pot manner, and 2-mercaptobenzoxazoles were synthesized (yield: 55?80%) in the presence of K2CO3 by treating o-aminophenols with tetramethylthiuram disulfide (TMTD). The feature of this method includes good to excellent yield, easy performance and broad substrate scope, which makes the protocol practical and attractive in the preparation of some potential pharmaceutically active compounds.

Unexpected TFA-catalyzed tandem reaction of benzo[d]oxazoles with 2-oxo-2-arylacetic acids: Synthesis of 3-aryl-2H-benzo[b][1,4]oxazin-2-ones and cephalandole A

A convenient and efficient method for the TFA-catalyzed synthesis of 3-aryl-2H-benzo[b][1,4]oxazin-2-ones via a tandem reaction of benzo[d]oxazoles with 2-oxo-2-arylacetic acids was reported for the first time. The efficiency of this transformation was demonstrated by compatibility with a wide range of functional groups. The synthetic utility of this method was confirmed by the synthesis of the natural product cephalandole A. Moreover, a plausible mechanism for the formation of 3-aryl-2H-benzo[b][1,4]oxazin-2-ones involving ring-opening and cyclization steps is proposed. The present synthetic route to 3-aryl-2H-benzo[b][1,4]oxazin-2-ones could be readily scaled up to gram quantity without difficulty.

Facile construction of three-membered rings via benzyne-promoted Darzens-type reaction of tertiary amines

A range of tertiary amines having electron-withdrawing groups were activated in situ by benzyne, generated from 2-(trimethylsilyl)phenyl triflate and a fluoride source, and participated in the Darzens-type reaction with carbonyl compounds, imines, and vinyl ketones to afford structurally diverse epoxides, aziridines, and cyclopropanes, respectively, in moderate to excellent yields with high trans-selectivity. The reaction involves in situ formation of unstrained ammonium ylides from tertiary amines and benzyne, proceeds in the absence of transition metals and strong bases, and tolerates a wide variety of functional groups.

Functional characterization of human and cynomolgus monkey cytochrome P450 2E1 enzymes

Cytochrome P450 2E1 (CYP2E1) is an enzyme of major toxicological interest because it metabolizes various drugs, precarcinogens and solvents to reactive metabolites. In this study, human and cynomolgus monkey CYP2E1 cDNAs (humCYP2E1 and monCYP2E1, respectively) were cloned, and the corresponding proteins were heterologously expressed in yeast cells to identify the functions of primate CYP2E1s. The enzymatic properties of CYP2E1 proteins were characterized by kinetic analysis of chlorzoxazone 6-hydroxylation and 4-nitrophenol 2-hydroxylation. humCYP2E1 and monCYP2E1 enzymes showed 94.3% identity in their amino acid sequences. The functional CYP content in yeast cell microsomes expressing humCYP2E1 was 38.4 pmol/mg protein. The level of monCYP2E1 was 42.7% of that of humCYP2E1, although no significant differences were statistically observed. The Km values of microsomes from human livers and yeast cells expressing humCYP2E1 for CYP2E1-dependent oxidation were 822 and 627 muM for chlorzoxazone 6-hydroxylation, and 422 and 514 muM for 4-nitrophenol 2-hydroxylation, respectively. The Km values of microsomes from cynomolgus monkey livers and yeast cells expressing monCYP2E1 were not significantly different from those of humans in any enzyme source. Vmax and Vmax / Km values of human liver microsomes for CYP2E1-dependent oxidation were 909 pmol/min/mg protein and 1250 nl/min/mg protein for chlorzoxazone 6-hydroxylation, and 1250 pmol/min/mg protein and 2990 nl/min/mg protein for 4-nitrophenol 2-hydroxylation, respectively. The kinetic parameter values of cynomolgus monkey livers were comparable to or lower than those of human liver microsomes (49.5-102%). In yeast cell microsomes expressing humCYP2E1, Vmax and Vmax / Km values for CYP2E1-dependent oxidation on the basis of CYP holoprotein level were 170 pmol/min/pmol CYP and 272 nl/min/pmol CYP for chlorzoxazone 6-hydroxylation, and 139 pmol/min/pmol CYP and 277 nl/min/pmol CYP for 4-nitrophenol 2-hydroxylation, respectively, and the kinetic parameters of monCYP2E1 exhibited similar values. These findings suggest that human and cynomolgus monkey CYP2E1 enzymes have high homology in their amino acid sequences, and that their enzymatic properties are considerably similar. The information gained in this study should help with in vivo extrapolation and to assess the toxicity of xenobiotics.
