Two new series of benzonitrile derivatives on position 6 or 4 of indole ring were successfully synthesized via a Leimgruber-Batcho reaction. All the compounds were evaluated in vitro on the inhibition of aromatase (CYP19) and 17alpha-hydroxylase-C17,20-lyase (CYP17). The racemate, 4-[(1H-imidazol-1-yl)(1H-indol-4-yl)methyl]benzonitrile 9, showed high level of inhibitory activity towards CYP19 (IC(50)=11
通过Leimgruber-Batcho反应成功地合成了两个新的吲哚环的6或4位上的苄腈衍生物系列。体外评估了所有化合物对芳香化酶(CYP19)和17α-羟化酶-C17,20-裂合酶(CYP17)的抑制作用。外消旋物4-[((1H-咪唑-1-基)(1H-吲哚-4-基)甲基]苯甲腈9)对CYP19表现出高水平的抑制活性(IC(50)= 11.5 nM)。
