Mineralocorticoid receptor (MR) antagonists continue to be a prevalent area of research in the pharmaceutical industry. Herein we report the discovery of various spirooxindole and dibenzoxazepine constructs as potent MR antagonists. SAR analysis of our spirooxindole hit led to highly potent compounds containing polar solubilizing groups, which interact with the helix-11 region of the MR ligand binding
盐皮质激素受体(MR)拮抗剂继续是制药行业研究的主要领域。在本文中,我们报道了作为有效的MR拮抗剂的各种螺氧杂吲哚和二苯并x庚因构建物的发现。SAR分析我们的螺氧杂吲哚导致了含有极性增溶基团的高效化合物,这些基团与MR配体结合域(LBD)的11螺旋区域相互作用。为了替代已知的与MR LBD的疏水区相互作用的二苯并庚烷体系,还制备了各种二苯并x庚因部分。另外,从高效化合物获得了X射线晶体结构,该化合物显示出针对MR的部分激动剂和拮抗剂作用模式。
