3-triazole tagged pyrazolo[3,4-b]pyridine derivatives 3 and 4 were prepared respectively starting from 6-phenyl-4-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridin-3-amine 1 via selective N-propargylation, followed by reaction with diverse substituted alkyl/perfluoroalkyl/aryl/aryl amide azides under Sharpless conditions. All the synthesized compounds 3 and 4 were screened for cytotoxic activity against four
一系列新颖的1,2,3-三唑标记的吡唑并[3,4的b ]吡啶衍生物3和4被分别制备由6-苯基-4-(三氟甲基)-1 ħ -吡唑并[3,4- b通过选择性N-炔丙基化]吡啶3-胺1,然后在Sharpless条件下与各种取代的烷基/全氟烷基/芳基/芳基酰胺叠氮化物反应。筛选所有合成的化合物3和4对四种人类癌细胞系如U937,THP-1,HL60和B16-F10的细胞毒活性。化合物3e,4g,4i和4j 已经证明了显示出有希望的活动。
