a novel strategy for the treatment of congestive heart failure and myocardial fibrosis. In this study the synthesis and biological evaluation of heteroaryl-substituted naphthalenes and quinolines (1-31) is described. Key step for the preparation of the compounds was a Suzuki cross-coupling. Activity of the compounds was determined in vitro using human CYP11B2 and selectivity was evaluated toward the
最近,我们提出抑制醛固酮合酶(CYP11B2)作为一种治疗充血性心力衰竭和心肌纤维化的新策略。在这项研究中,描述了杂芳基取代的萘和喹啉(1-31)的合成和生物学评估。制备化合物的关键步骤是铃木交叉偶联。使用人CYP11B2在体外确定化合物的活性,并评估对人类固醇生成酶CYP11B1,CYP19和CYP17的选择性。已鉴定出大量的CYP11B2高活性和选择性抑制剂。活性最高的抑制剂是6-氰基化合物8(IC50 = 3 nM),显示出竞争性的抑制类型(K(i)值= 1.9 nM)。发现6-乙氧基衍生物5是最具选择性的CYP11B2抑制剂(IC50 = 12 nM; K(i)值= 8 nM; CYP11B1 IC50 = 5419 nM;选择性因子= 451),显示没有对人CYP3A4(50 nM)和CYP2D6(20 nM)的抑制作用。使用我们的同源性建模的CYP11B2结构与所选化合物进行了
