sufficient exposure in rats and excellent exposure in dogs upon oral dosing. In pharmacodynamic studies, compound 22 dose-dependently suppressed growth hormone (GH) secretion induced by an exogenous growth-hormone-releasing hormone (GHRH) challenge in both male and female rats following a single oral dose and suppressed IGF-1 levels with repeated oral administration in both rats and dogs. To the best of our
描述了一种新型 4-(4-氨基哌啶基)-3,6-二芳基喹啉系列强效 SST2 激动剂的发现。此类分子对 SST1、SST3、SST4 和 SST5 受体具有出色的选择性。化合物 3-[4-(4-aminopiperidin-1-yl)-3-(3,5-difluorophenyl)quinolin-6-yl]-2-hydroxybenzonitrile ( 22 , paltusotine, 以前称为 CRN00808) 没有显示出直接抑制作用主要细胞色素 P450 酶或 hERG 离子通道,在大鼠中有足够的暴露,在狗中有很好的暴露。在药效学研究中,化合物22剂量依赖性地抑制由外源性生长激素释放激素 (GHRH) 诱导的生长激素 (GH) 分泌,在雄性和雌性大鼠中单次口服剂量后,在大鼠和狗中重复口服给药后抑制 IGF-1 水平. 据我们所知,化合物22是第一个进入人体临床试验的非肽类 SST2
