Synthesis and biological evaluation of novel 2,3-disubstituted quinoxaline derivatives as antileishmanial and antitrypanosomal agents
Quinoxalines belong to the N-containing heterocyclic compounds that stand out as having promising biological activity due to their privileged scaffold. In this work, we report the synthesis, antileishmanial, and antitrypanosomal properties of 46 new 2,3-disubstituted quinoxaline and 40 previously reported derivatives. Among all of the compounds screened for in vitro activity against epimastigotes and trypomastigotes of Trypanosoma cruzi and promastigotes of Leishmania amazonensis as well as mammalian toxicity on LLCMK2 cells and J774 macrophages, analogues from series 5, 6, 7, 9, 12, and 13 displayed high activity at micromolar IC50 and EC50 concentrations. Sixteen quinoxaline derivatives were selected and evaluated on T. cruzi and/or L. amazonensis amastigotes. The most active compounds were 6a-b and 7d-e, on all evolutive forms of L. amazonensis and T. cruzi evaluated with IC50 values 0.1-0.8 muM on promastigotes and epimastigotes 1.4-8.6 on amastigotes. Compounds 5k, 12b and 13a were the most selective (SI = 19.5-38.4) on amastigotes of T. cruzi. In general their activity was directly related to the methylsulfoxyl, methylsulfonyl, and amine groups as well as the presence of chorine or bromine in the molecules. The current results indicate that these quinoxaline derivatives are novel and promising agents for further development towards a treatment for Chagasg ? disease and leishmaniasis.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 61964-08-7, and how the biochemistry of the body works.Reference of 61964-08-7
