Graphical Abstract:


Background: Near to 5-7 million people are infected with T. cruzi in the world, and about 10,000 people per year die of problems associated with this disease.

Methods: Herein, the synthesis, antitrypanosomal and antimycobacterial activities of seventeen coumarinic N-acylhydrazonic derivatives have been reported.

Results: These compounds were synthesized using methodology with reactions global yields ranging from 46%-70%. T. cruzi in vitro effects were evaluated against trypomastigote and amastigote, forming M. tuberculosis activity towards H37Rv sensitive strain and resistant strains.

Discussion: Against T. cruzi, the more active compounds revealed only moderate activity IC50/96h~20 μM for both trypomastigotes and amastigotes intracellular forms. (E)-2-oxo-N'- (3,4,5-trimethoxybenzylidene)-2H-chromene-3-carbohydrazide showed meaningful activity in INH resistant/RIP resistant strain.

Conclusion: These compound acting as multitarget could be good leads for the development of new trypanocidal and bactericidal agents.

Keywords: Antitrypanosomal, antimycobacterial, coumarine, N-Acylhydrazone, chagas, tuberculosis.
