The discovery of pyrrolopyrazines as potentantimalarialagents is presented, with the most effective compounds exhibiting EC50 values in the low nanomolar range against asexual blood stages of Plasmodium falciparum in human red blood cells, and Plasmodium berghei liver schizonts, with negligible HepG2 cytotoxicity. Their potential mode of action is uncovered by predicting macromolecular targets through
Synthesis and Mechanism Studies of 1,3-Benzoazolyl Substituted Pyrrolo[2,3-<i>b</i>]pyrazine Derivatives as Nonintercalative Topoisomerase II Catalytic Inhibitors
Novel topoisomerase II (Topo II) inhibitors have gained considerable interest for the development of anticancer agents. In this study, a series of 1,3-benzoazolyl-substituted pyrrolo[2,3-b]pyrazine derivatives were designed, synthesized, and evaluated as potential Topo II catalytic inhibitors. It was found that some of derivatives had good antiproliferative activity on seven cancer cell lines, especially
