A novel series of tetrahydroprotoberberine derivatives (THPBs) were designed, synthesized, and evaluated as selective α1A-adrenergic receptors (AR) antagonists for the treatment of benign prostatic hyperplasia. On the basis of the pharmacophore model of the marketed drug silodosin, THPBs were modified by introducing an indole segment into their core scaffolds. In calcium assays, 7 out of 32 compounds
一种新型系列tetrahydroprotoberberine衍生物(THPBs)的设计,合成和评价为选择性α 1A肾上腺素能受体(AR)拮抗剂用于良性前列腺增生的治疗。根据市售的药物西洛多辛的药效团模型,通过将吲哚片段引入其核心支架来修饰THPB。在钙化验中,32种化合物中有7种对α1A -ARs表现出优异的拮抗活性,IC 50小于250 nM。其中,化合物(S)-27具有最强的生物活性。其对α1A -AR的IC 50为12.8±2.2 nM,是对α1A -AR的781和20倍。1B -和α 1D -AR,分别。在使用离体大鼠组织的功能测定中,化合物(S)-27有效抑制去甲肾上腺素引起的尿道平滑肌收缩(IC 50 = 0.5±0.3 nM),而没有抑制主动脉收缩(IC 50 > 1000 nM),表现出更好的效果。组织选择性优于市售药物西洛多辛。初步安全性研究(急性毒性和hERG抑制作用)
