A novel series of substituted N-benzyl-N-phenyl-trifluoro-3-amino-2-propanols are described that reversibly inhibit cholesteryl ester transfer protein (CETP). Starting with screening lead 22, various structural features were explored with respect to inhibition of the CETP-mediated transfer of [(3)H]cholesterol from high-density cholesterol donor particles to low-density cholesterol acceptor particles
描述了可逆地抑制胆固醇酯转移蛋白(CETP)的一系列新的取代的N-苄基-N-苯基-三氟-3-氨基-2-丙醇。从筛选铅22开始,就抑制CETP介导的[(3)H]胆固醇从高密度胆固醇供体颗粒向低密度胆固醇受体颗粒的转移进行了探索,探讨了各种结构特征。丙醇的游离羟基是高效试剂所必需的,因为酰化或烷基化会降低活性。苯胺环中的3-醚部分也具有高抑制效力,而3-苯氧基苯胺类似物表现出最高的效力。活性通过苄基的亚甲基中的氧化或取代而大大降低,这表明苄基环取向对活性很重要。在苄基中,在3-位的取代优于在2-或4-位。在抑制剂中观察到最高的效力,其中3-苄基取代基具有相对于苯环采用平面外取向的潜力。最好的3-苄基取代基是OCF(2)CF(2)H(42,IC(50)缓冲液中0.14 microM,人血清中5.6 microM),环戊基(39),3-异丙氧基(27),SCF (3)(67)和C(CF(3))
