Synthesis and biological activities of pyrazolo(3,4-g)quinoxaline derivatives.

摘要

The synthesis of new pyrazolo[3,4-g]quinoxaline derivatives, as well as their Pim kinases (Pim-1, Pim-2, Pim-3) inhibitory potencies and in vitro antiproliferative activities toward a human fibroblast primary culture and three human solid cancer cell lines (PA1, PC3 and DU145) are described. The results obtained in this preliminary structure-activity relationship study have pointed out that most of the compounds in this series exhibited interesting in vitro Pim-3 kinase inhibitory potencies. Moreover, some of the tested compounds have demonstrated favorable antiproliferative potencies.
