novel 1,2,3-triazole substituted N-phenyl nitrone derivatives 5a–e were prepared in three steps starting from 1-substituted-1,2,3-triazole-4-carbaldehydes 2 via Schiff's base formation, reduction followed by oxidation. Similarly, 1,2,3-triazole substituted N-alkyl nitrone derivatives 6a–p were prepared in single step starting from compound 2 on reaction with N-alkyl hydroxylamine hydrochlorides. All the
分三个步骤制备了一系列新颖的1,2,3-三唑取代的N-苯基硝酮衍生物5a–e,该过程从1-取代的1,2,3-三唑-4-甲醛2开始,通过席夫碱的形成,然后还原通过氧化。同样,从化合物2开始,与N-烷基羟胺盐酸盐反应,即可一步制备1,2,3-三唑取代的N-烷基硝酮衍生物6a-p。筛选所有最终化合物针对各种癌细胞系的抗炎和抗癌活性。在测试的化合物中,化合物5a,5d,6a,图6b,6m和6o显示出对IL-1β分泌的显着抑制,作为抗炎活性的量度。化合物5b,5c,6h,6i和6o对所有细胞系(A549,COLO 205,MDA-MB 231和PC-3)表现出显着的活性,IC 50值小于15μM。
