functionalized pyrazolo[3,4-b]pyridine derivatives (6a-n)was synthesized using 6-thiophenyl-4-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridin-3-amine (1) through reaction with 2-bromoethyl acetate, followed by hydrazine hydrate to afford hydrazide derivatives (5). These compounds were further treated with aromatic acids in the presence of phosphoryl chloride and obtained oxadiazole functionalized pyrazolo[3,4-b]pyridine
采用6-噻吩基-4-(三氟甲基)-1H-吡唑并[3,4-b]吡啶-3-胺合成了一系列新型恶二唑官能化吡唑并[3,4-b]吡啶衍生物(6a-n)(6a-n)。 1)与2-溴乙酸乙酯反应,再与水合肼反应,得到酰肼衍生物(5)。这些化合物在磷酰氯存在下进一步用芳香酸处理,得到恶二唑官能化的吡唑并[3,4-b]吡啶衍生物(6a-n)。筛选所有合成的化合物6a-n对HeLa-宫颈癌(CCL-2)等四种癌细胞系的抗癌活性;COLO 205-结肠癌(CCL-222);HepG2-肝癌(HB-8065);MCF7-乳腺癌(HTB-22)。发现化合物6i、6m和6n在微摩尔浓度下具有更显着的抗癌活性。
