tissue-selective androgen receptor modulators (SARMs), represented by a naphthalene derivative A. However, their pharmacokinetic (PK) profiles were poor due to low metabolic stability. To improve the PK profiles, we modified the hydroxypyrrolidine and benzonitrile substituents of 4-(pyrrolidin-1-yl)benzonitrile derivative B, which had a comparable potency as that of compound A. This optimization led us
我们最近报道了一类新型的组织选择性雄激素受体调节剂(
SARMs),以
萘衍
生物A为代表。但是,由于代谢稳定性低,它们的药代动力学(PK)状况很差。为了改善PK谱,我们修饰了4-(
吡咯烷-1-基)
苄腈衍
生物B的羟基
吡咯烷和
苄腈取代基,其效力与化合物A相当。这种优化使我们进行了进一步的修饰,从而改善了代谢稳定性同时保持有效的雄激素激动活性。在合成的化合物中,(2S,3S)-2,3-二甲基-
3-羟基吡咯烷衍
生物1c表现出合适的PK曲线和改善的代谢稳定性。在体内研究中,化合物1c在提肛肌中显示出显着的功效,而没有增加前列腺的重量。
