Abstract
Some novel 6-substituted pyrazolo[3,4-d]pyrimidines 4, 5, 6a-d, 7a-c, 8 and pyrazolo[4,3-e][1,2,4]triazolo[4,3-a]pyrimidines 9a-c, 10a-c, 11, 12a,b, 13a-c and 14 were synthesized and characterized by spectral and elemental analyses. They were screened for their biological activity in vitro against Abl and Src kinases. Compounds 7a and 7b revealed the highest activity against both wild and mutant Abl kinases as well as the Src kinase and the leukemia K-562 cell line. They can be considered as new hits for further structural optimization to obtain better activity.
Keywords:
Abl inhibition; K-562 cell line; Molecular modeling; Pyrazolo[3,4-d]pyrimidines; Src inhibition.
