Human microsomal cytochrome P450 (CYP) 2A6 contributes extensively to nicotine detoxication but also activates tobacco-specific procarcinogens to mutagenic products. We prepared a series of benzofuran and coumarin derivatives that have inhibitory effects on the activity of human CYP2A6. The reported compounds methoxalen and menthofuran had potent inhibitory effects on the activity of CYP2A6 with IC50 values of 0.47 µM and 1.27 µM, respectively. Synthetic benzofuran (4-methoxybenzofuran: IC50=2.20 µM) and coumarin (5-methoxycoumarin: IC50=0.13 µM and 6-methoxycoumarin: IC50=0.64 µM) derivatives, which have more selective effects than those of methoxalen and menthofuran, exhibited comparable activities against CYP2A6. These compounds can be used as a lead compounds in the design of CYP2A6 inhibitor drugs to reduce smoking and tobacco-related cancers.
人类微粒体细胞色素 P450 (CYP) 2A6 对尼古丁的解毒作用很大,但也能激活烟草特异性致癌物质,使其产生致突变产物。我们制备了一系列对人类 CYP2A6 活性有抑制作用的苯并呋喃和香豆素衍生物。已报道的化合物甲氧呋喃和薄荷呋喃对 CYP2A6 的活性有很强的抑制作用,其 IC50 值分别为 0.47 µM 和 1.27 µM 。合成苯并呋喃(4-甲氧基苯并呋喃:IC50=2.20 µM )和香豆素(5-甲氧基香豆素:IC50=0.13 µM 和 6-甲氧基香豆素:IC50=0.64 µM) 衍生物对 CYP2A6 的活性相当,它们比甲氧沙林和薄荷呋喃的选择性更强。这些化合物可用作设计 CYP2A6 抑制剂药物的先导化合物,以减少吸烟和与烟草有关的癌症。
