and evaluated for inhibition of rat and human steroid 5alpha-reductase isozymes types 1 and 2. In the dicyclohexylacetyl series, fluorination in the 2-position of the benzene nucleus (15), exchange of the carboxy group by a carboxymethyl moiety (20), and combination of both structural modifications (25) led to highly active inhibitors of the human type 2 isozyme (IC(50) values: 15, 11 nM; 20, 6 nM;
合成了16种衍生自N-酰基-4-苄叉亚哌啶-4'-羧酸的化合物,并评估了它们对1型和2型大鼠和人类固醇5α-还原酶同工酶的抑制作用。在二环己基乙酰基系列中,氟在2位的位置苯核(15),羧甲基部分的羧基交换(20)和两种结构修饰的组合(25)导致了人类2型同工酶的高活性抑制剂(IC(50)值:15,11 nM ; 20,6 nM; 25,7 nM;非那雄胺,5 nM)。在体内,所有测试化合物均显着降低了去势睾丸激素治疗大鼠的前列腺重量。显示了化合物7的口服活性。从发现化合物15在大鼠中具有活性的发现来看,尽管它是大鼠酶的一种较弱的抑制剂,并且是人类酶的一种强抑制剂,
