In a continuing effort to identify new active compounds for combating Chagas disease and other neglected diseases, our research group synthesized and evaluated 23 3-arylquinoxaline-2-carbonitrile di-N-oxides against Trypanosoma cruzi. Five of them presented IC50 values of the same magnitude as the standard drug Nifurtimox, making them valid as new lead compounds. The optimized molecular structures of 23 derivatives represented by 1497 types of DRAGON descriptors were subjected to linear regression analysis, and the derived QSAR was shown to be predictive. In this way, we achieved a rational guide for the proposal of new candidate structures whose activities still remain unknown.
Graphical abstractIn vitro anti-Trypanosoma cruzi activity and QSAR studies of 3-arylquinoxaline-2-carbonitrile di-N-oxides is reported, emerging as new anti-trypanosomal agents. In addition, a rational guide for the proposal of new candidate structures is achieved.Figure optionsDownload full-size imageDownload as PowerPoint slide
