Mineralocorticoid receptor (MR) blockade has come into focus as a promising approach for the treatment of cardiovascular diseases such as hypertension and congestive heart failure. In order to identify a novel class of nonsteroidal MR antagonists that exhibit significant potency and good selectivity over other steroidal hormone receptors, we designed a novel series of benzoxazin-3-one derivatives and synthesized
盐皮质激素受体(MR)阻断已成为治疗心血管疾病(如高血压和充血性心力衰竭)的一种有前途的方法。为了确定一类新型的非甾体MR拮抗剂,它们比其他甾体激素受体具有显着的效力和良好的选择性,我们设计了一系列新颖的benzoxazin-3-one衍生物,并从6-(7 H- [1,2 ,4] triazolo [3,4- b ] [1,3,4]噻二嗪-6-基)-2 H -1,4-苯并恶嗪-3(4 H)-one(1a),高通量筛选( HTS)命中化合物。我们的设计基于MR /化合物配合物的晶体结构和对接模型。在从1a开始产生线索的过程中,1,2-二芳基骨架被表征为具有高结合亲和力的关键结构。基于支架跳跃和优化研究,在6-位具有1-苯基-3-三氟甲基吡唑-5-基部分的苯并恶嗪-3-酮衍生物被鉴定为一系列有效的和选择性的MR拮抗剂。在这些化合物中,6- [1-(4-氟-2-甲基苯基)-3-(三氟甲基)-1 H-吡唑-5-基]
