A series of novel Schiff' base‐containing a 7‐amino‐4‐methylcoumarin moiety have been synthesized III a–l, characterized by spectroscopic data and studied for their anti‐inflammatory and analgesic activity. The results of the anti‐inflammatory and analgesic activity evaluation of 7‐(substitutedbenzylideneamino)‐4‐methyl‐2H‐chromen‐2‐one derivatives III a–l proved to be comparable or more potent with

A series of 7-(2-substituted phenylthiazolidinyl)-benzopyran-2-one derivatives have been synthesized by reaction of 7-amino-4-methyl-benzopyran-2-one (1) with an appropriate substituted aldehydes to obtain various Schiff bases (3a–k) which on treatment with thioglycolic acid afforded the title compounds (4a–k). Purity of the compounds has been confirmed by TLC. Structure of these compounds were established
通过使7-氨基-4-甲基-苯并吡喃-2-酮(1)与适当的取代醛反应以获得各种席夫碱,合成了一系列的7-(2-取代的苯基噻唑烷基)-苯并吡喃-2-酮衍生物。 (3a - k),其在用巯基乙酸处理后得到标题化合物(4a - k)。化合物的纯度已通过TLC证实。这些化合物的结构基于IR,1 H NMR,1313 C NMR和质谱数据。评估席夫碱和标题化合物对各种细菌和真菌菌株的抗菌和抗真菌活性。结果表明,化合物3d,3f,4d,4f和4i(100μg/ ml)与标准抗生素环丙沙星和灰黄霉素一样具有良好的抗菌和抗真菌活性。
