The reaction of one equivalents of 5‐acetylthiadiazole with one equivalent of aldehyde in acetic acid and ammonium acetate yielded thiadiazolyl‐pyridine derivatives in a multicomponent reactions. The structures of all the new compounds were elucidated on the basis of elemental analysis and spectral data. The anticancer activities of the synthesized compounds were screened for their activity against
一当量的5-乙酰基噻二唑与一当量的醛在乙酸和乙酸铵中的反应在多组分反应中生成噻二唑基-吡啶衍生物。在元素分析和光谱数据的基础上阐明了所有新化合物的结构。筛选合成的化合物对人肺癌(A549)和与顺铂相当的人肝癌细胞系(HepG2)的抗癌活性,结果表明大多数此类化合物表现出相当大的活性。活性对A549细胞系中的顺序为图4c,4e中,图4a,图6d,8d中,11,12,4b,4f和4d。然而,化合物4e中表现出对HepG2细胞活性最高,其次是图4a,图4c,图6d,8d中,11,12,图4F,图4D,和图4b。在另一方面,化合物11,12,和图4b显示出最高的2,2-二苯基-1-苦基肼自由基清除活性。总而言之,当前研究的结果证实了合成化合物的细胞毒性和抗氧化能力。
