A series of N-substituted heteroaromatic compounds structurally related to clotrimazole was synthesized, and the effects of these compounds on ethosuximide clearance in rats were determined as a measure of their abilities to induce cytochrome P4503A (CYP3A) activity. Ethosuximide clearance and in vitro erythromycin N-demethylase activity were shown to correlate. In this series, imidazole or other related
合成了一系列与克霉唑相关的N-取代杂芳族化合物,并确定了这些化合物对大鼠乙硫酰亚胺清除率的影响,以此来衡量它们诱导细胞色素P4503A(CYP3A)活性的能力。乙草胺清除率和体外红霉素N-脱甲基酶活性显示出相关性。在该系列中,咪唑或其他相关的杂芳族“头基”与三苯基甲烷或其他苯基甲烷衍生物连接。在该系列中,发现1-三苯基甲烷取代的咪唑引起CYP3A活性的最大增加,而在三苯基甲基取代的咪唑中,通过间位或Cl-中的F-或Cl-取代获得最高的活性。苯环之一的对位。二苯甲基取代的吡啶实际上没有活性。引起CYP3A活性最大增加的化合物(即1-[((3-氟苯基)二苯基甲基]咪唑,1-[((4-氟苯基)二苯基甲基]咪唑和1- [三-(4-氟苯基)甲基]咪唑)产生的乙氧基间苯二酚O-脱烷基酶(EROD)活性(即CYP1A)几乎没有增加,而苄基咪唑仅引起CYP3A活性少量增加,而CYP1A活性几乎增加了9倍。
