Synthesis of new pyrazolo[5,1-c][1,2,4] benzotriazines, pyrazolo[5,1-c]pyrido[4,3-e][1,2,4] triazines and their open analogues as cytotoxic agents in normoxic and hypoxic conditions.
The synthesis and antitumor activity in normoxic and hypoxic conditions of a series of pyrazolo[5,1-c][1,2,4]benzotriazine and its related analogues are reported. All compounds were tested on human colorectal adenocarcinoma cell line HCT-8 and for compounds 15 and 20, which show to have selective cytotoxicity in hypoxic and in normoxic conditions respectively, ROS production, cell cycle, and DNA fragmentation were measured. This preliminary study encouraged us to consider 15 and 20 as interesting leads for further optimization.
