A series of novel oxadiazole 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

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 5, 6 and 7 were screened for anticancer activity against four cancer cell lines such as A549 - Lung cancer (CCL-185), MCF7 - Breast cancer (HTB-22), DU145 - Prostate cancer (HTB-81) and HeLa - Cervical cancer (CCL-2). The compounds 5i and 6e are found to have promising bioactivity at micro molar concentration.
A new synthetic route to fluorinated pyrazolo[3,4-b]pyridines and their use in the preparation of novel pyrido[2′,3′:3,4] pyrazolo [1,5-a]pyrimidines
