new potent and selective 5alphaR inhibitors is thus of great interest for pharmaceutical treatment of these diseases. The synthesis of a novel class of inhibitors for human 5alphaR-1 and 5alphaR-2, having the 19-nor-10-azasteroid skeleton, is described. The inhibitory potency of the 19-nor-10-azasteroids was determined in homogenates of human hypertrophic prostates toward 5alphaR-2 and in DU-145 human
类固醇5alpha还原酶是由两种同功酶(5alphaR-1和5alphaR-2)组成的系统,该酶在许多雄激素敏感组织中催化NADPH依赖的睾丸激素还原为二氢睾丸激素,并且与几种人类内分泌疾病如良性前列腺增生( BPH),前列腺癌,痤疮,脱发,男性型秃发和女性多毛症。因此,对于这些疾病的药物治疗,新的有效的和选择性的5alphaR抑制剂的发现引起了极大的兴趣。描述了具有19-nor-10-氮杂甾类骨架的新型人5alphaR-1和5alphaR-2抑制剂的合成。在人肥大性前列腺的匀浆中对5alphaR-2和DU-145人前列腺腺癌细胞对5alphaR-1的抑制,确定了19-nor-10-氮杂甾类化合物的抑制能力,与非那雄胺相比(对于5alphaR-2,IC50 = 3 nM,对于5alphaR-1,IC50 = 42 nM),该药物目前用于BPH治疗。抑制能力取决于位置17处取代基的类型以及A
