KF20405) showed the maximum potency with an IC50 value of 0.48 +/- 0.086 nM, which was 20-fold higher potency than 1 (MK-906). Compound 16 effectively inhibited DHT production 4 h after a 3 mg/kg oral administration. Several potent indole derivatives, 1 and 2 ((+/-)-ONO-3805), were tested versus rat and human isozymes. Nonsteroidal inhibitors such as indole derivatives and 2 were 2-3 orders of magnitude
合成了一系列在α,β-不饱和双键上具有不同取代基的吲哚衍生物,并评估了它们抑制大鼠前列腺5α-还原酶的能力。在双键的β位上具有乙基取代基的化合物显示出有效的抑制活性。其中,(Z)-4- 2-[[[3- [1-(4,4'-二氟苯氢基)吲哚-5-基] -2-戊烯l]-氨基]苯氧基}丁酸(16,KF20405 )显示最大效能,IC50值为0.48 +/- 0.086 nM,比1(MK-906)高20倍。口服3 mg / kg后4小时,化合物16有效抑制了DHT的产生。与大鼠和人类同工酶相比,测试了几种有效的吲哚衍生物1和2((+/-)-ONO-3805)。
