Synthesis and biological evaluation of novel selective androgen receptor modulators (SARMs) Part III: Discovery of 4-(5-oxopyrrolidine-1-yl)benzonitrile derivative 2f as a clinical candidate
previously reported that 4-(pyrrolidin-1-yl)benzonitrile derivative 1b was a selective androgen receptor modulator (SARM) that exhibited anabolic effects on organs such as muscles and the central nervous system (CNS), but neutral effects on the prostate. From further modification, we identified that 4-(5-oxopyrrolidine-1-yl)benzonitrile derivative 2a showed strong AR binding affinity with improved metabolic

Novel gamma-aminobutyric acid receptor (GABAAR) ligands structurally related to imidazobenzodiazepine MIDD0301 were synthesized using spiro-amino acid N-carboxyanhydrides (NCAs). These compounds demonstrated increased resistance to phase 2 metabolism and avoided the formation of a 6H isomer. Compound design was guided by molecular docking using the available crystal structure of the α1β3γ2 GABAAR and
使用螺氨基酸 N-羧酸酐 (NCA) 合成了与咪唑并苯二氮卓 MIDD0301 结构相关的新型 γ-氨基丁酸受体 (GABA A R) 配体。这些化合物表现出对 2 相代谢的抵抗力增强,并避免了 6H 异构体的形成。化合物设计以分子对接为指导,使用 α 1 β 3 γ 2 GABA A R 的可用晶体结构,并与体外结合数据相关。含有GABA A R配体的羧酸具有高水溶性、低渗透性和低细胞毒性。 GABA A R 配体无法穿过血脑屏障,这在体内通过不存在感觉运动抑制而得到证实。肺 GABA A R 的药理活性通过离体豚鼠气道平滑肌松弛和清醒小鼠乙酰甲胆碱诱导的气道高反应性 (AHR) 的减少得到证实。我们鉴定出支气管扩张剂5c对 GABA A R 的亲和力为 9 nM,在人类和小鼠微粒体存在下代谢稳定。
