malonate followed by deprotection and cyclization gave the macrocyclic frame. Further manipulation gave the desired compounds. Unlike the ortho-substituted benzofused macrocyclic lactams described in the previous paper which are selective NEP inhibitors, the meta-substituted compounds are dual inhibitors of both NEP and ACE. The most potent member of this new series, compound 16a, inhibited both enzymes with
描述了间取代苯并稠合的大环内酰胺的设计,合成和生化特征。设计间位取代的苯并稠合的大环内酰胺,使其具有一定程度的柔韧性,以使酰胺键占据两个完全不同的构象,同时保持足够的刚度以允许酶和抑制剂之间的强相互作用。使用TFIT,一种新颖的分子叠加程序,它显示出元类似物可以很容易地叠加到我们的ACE抑制剂模板上,而找不到低能量的邻位取代大环化合物的叠加。通过将衍生自S-谷氨酸或S-天冬氨酸的醛1束缚在间位取代的溴化2. 2上制备大环。均一化为单羧酸丙二酸甲酯,然后脱保护并环化,得到大环骨架。进一步操作得到所需化合物。不同于先前论文中描述的邻位取代的苯并稠合大环内酰胺是选择性NEP抑制剂,间位取代的化合物是NEP和ACE的双重抑制剂。该新系列中最有效的化合物16a抑制了这两种酶,在NEP中的IC50 = 8 nM,在ACE中的IC50 = 4 nM。
