with a flexible aryl group bonded through a one-atom linker as a new scaffold for a corticotropin-releasing factor 1 (CRF1) receptor antagonist were designed, synthesized, and evaluated. We expected that structural diversity could be expanded beyond that of reported CRF1 receptor antagonists. In a structure–activity relationship study, 4-chloro-N2-(4-chloro-2-methoxy-6-methylphenyl)-1-methyl-N7,N7
设计,合成和评估了具有柔性芳基基团的苯并唑衍生物,该柔性芳基基团通过一个原子连接基作为一种新型的促肾上腺皮质激素释放因子1(CRF 1)受体拮抗剂的支架。我们期望结构多样性可以扩展到已报道的CRF 1受体拮抗剂之外。在结构-活性关系研究中,4-氯-N 2-(4-氯-2-甲氧基-6-甲基苯基)-1-甲基-N 7,N 7-二丙基-1 H-苯并咪唑-2,7-二胺29g对人CRF 1受体具有最强的结合活性和拮抗活性(IC 50分别为9.5和88 nM),而无需担心30μM时的细胞毒性。在小鼠口服后,在138μmol / kg的化合物29g中,还观察到了离体试验中大脑中有效的CRF 1受体结合活性以及对应激诱导的下丘脑-垂体-肾上腺皮质(HPA)轴激活的抑制作用。因此,新设计的苯并咪唑29g具有体内CRF 1受体拮抗活性和良好的脑渗透性,表明它是CRF 1受体拮抗剂药物发现研究的有希望的先导。
