The design, synthesis, and biological activity of a new class of highly potent non-peptide AII receptor antagonists derived from N-substituted (phenylamino)phenylacetic acids and acyl sulfonamides which exhibit a high selectivity for the AT1 receptor are described. A series of N-substituted (phenylamino)phenylacetic acids (9) and acyl sulfonamides (16) and a tetrazole derivative (19) were synthesized
描述了衍生自对AT1受体具有高选择性的N-取代的(苯基氨基)苯基乙酸和酰基磺酰胺衍生的新型高效的非肽AII受体拮抗剂的设计,合成和生物学活性。合成了一系列N-取代的(苯氨基)苯乙酸(9)和酰基磺酰胺(16)和四唑衍生物(19),并在体外AT1(兔主动脉)和AT2(大鼠中脑)结合测定中进行了评估。(苯基氨基)苯乙酸9c(AT1 IC50 = 4 nM,AT2 IC50 = 0.74 microM),9d(AT1 IC50 = 5.3 nM,AT2 IC50 = 0.49 microM)和9e(AT1 IC50 = 5.3 nM,AT2 IC50 = 0.56 microM)被发现是该酸系列中最有效的AT1选择性AII拮抗剂。在中心和底部苯环中引入各种取代基会导致所得化合物的AT1和AT2结合亲和力下降。用生物等排酯酰基磺酰胺(CONHSO2Ph)替代9c,9d和9e中的羧酸(CO2H)导致AT1效能16a升高(5-7)倍(AT1
