N-cyclohexyl group in compound 8 and 1,2,4-oxadiazole nucleus in compound 9 were responsible for its low activity. Glucoglycero-triazole-oxadiazole derivatives 5e (10 μM) and 7 (23.9 μM) were the most promising antitubercular compounds, showing a better selective index than when tested against RAW 264.7 and HepG2 cells. Vero cell were used to investigate cytotoxicity of compounds 5a, 5h, 5j, 5k, and
共合成43种化合物,包括32种新化合物。在这些化合物中,选择了 17 种化合物并在人类肿瘤细胞系上进行测试:PC-3(前列腺腺癌)、HCT-116(结直肠肿瘤)、NCIH-460(肺癌)、SKMEL-103(黑色素瘤)和 AGP-01(胃肿瘤)。炔基化的 1,2,4-恶二唑2m、3g和3k在培养中表现出针对 NCIH-460 的抗增殖活性。炔基化Ñ -环己基-1,2,4-恶二唑3A-M和二-杂环glucoglycero-1,2,3-三唑ñ -环己基-1,2,4-恶二唑衍生物5A-K和6-11进行了评价对于他们的体外对结核分枝杆菌( Mtb ) H 37 Ra 和H 37 Rv 菌株的功效。通常,通过 1,2,3-三唑键(5a、5e、5j、5k和7)与 1,2,4-恶二唑缀合的甘油糖显示出对Mtb ( H 37 Rv) 的体外抑制活性。最大的分子双三唑10和11被证明对结核病无活性。可能是化合物8
