A series of novel alkyl amide functionalized trifluoromethyl substituted pyrazolo[3,4-b]pyridine derivatives 5, 6 and 7 were prepared starting from 6-phenyl-4-(trifluoromethyl)-1H-pyrazolo[3,4-b]pyridin-3-amine 3 via selective N-alkylation, followed by reaction with different primary aliphatic amines, cyclic secondary amines or l-amino acids under different set of conditions. All the synthesized compounds
一系列新颖的烷基酰胺官能三氟甲基取代的吡唑并[3,4 -b ]吡啶衍生物5,6和7分别开始制备自6-苯基-4-(三氟甲基)-1H-吡唑并[3,4- b ]吡啶通过选择性的N-烷基化作用生成3-胺3,然后在不同的条件下与不同的伯脂族胺,环状仲胺或1-氨基酸反应。所有合成的化合物5,6和7筛选了针对四种癌细胞系(例如A549-肺癌(CCL-185),MCF7-乳腺癌(HTB-22),DU145-前列腺癌(HTB-81)和HeLa-宫颈癌(CCL-2)的抗癌活性)。发现化合物5i和6e在微摩尔浓度下具有有前途的生物活性。
