A new series of sulfonamide derivatives of pyrazolo[4,3-e][1,2,4]triazine has been synthesized and characterized. Their anticancer activity was tested in vitro against multiple human cancer cell lines and were found to have dose-dependent antiproliferative effects. Furthermore, some of the new compounds inhibited the Abl protein kinase with low micromolar IC50 values and exhibited selective activity against the Bcr-Abl positive K562 and BV173 cell lines, providing starting points for the further development of this new kinase inhibitor scaffold.
