ne as starting material a number of 8-substituted derivatives (i.e., hydrazones 2a,b, imine 2c, chalcones 3, pyrazoles 4, 3-cyano-2-oxo-dihydropyridines 5, and/or 3-cyano-2-imino-dihydropyridines 6) were synthesized and assayed for their anti-inflammatory, analgesic and antipyretic activities. Compounds 3c, 4b and 4i showed significant anti-inflammatory, analgesic and antipyretic activities. In addition
8-乙酰基-7-羟基-4-苯基-2- ħ苯并吡喃-2-酮作为起始原料的数8取代的衍生物(即,腙的图2a,b,亚胺2C,查耳酮3,吡唑4,3-氰基合成了-2-氧代二氢吡啶5和/或3-氰基-2-亚氨基二氢吡啶6,并测定了它们的抗炎,镇痛和解热活性。化合物3c,4b和4i显示出显着的抗炎,止痛和解热活性。此外,1,3B,4D,4E,5b,6a,6c,6d,6e表现出抗炎作用,2b,4h,5e表现出镇痛作用,2b,4h,5e表现出退烧作用。此外,为了预测合成化合物在活性位点的亲和力和方向,使用molsoft icm 3.4-8C程序对被测化合物与其结合的抑制剂吲哚美辛(4COX)复合的环加氧酶II进行了分子建模和对接。此外,人们发现,活性化合物1,4I,6a – e与丝氨酸530和酪氨酸385氨基酸相互作用,这是参与环氧合酶II抑制机制的主要氨基酸。 含吡唑的新化合物4的合成证明成功。同样,3-氰
