GARCIA-MONROY, Ricardo et al. Synthesis of Novel Benzylic 1,2,3-triazole-4-carboxamides and their in vitro Activity Against Clinically Common Fungal Species. J. Mex. Chem. Soc [online]. 2021, vol.65, n.2, pp.202-213.  Epub June 04, 2021. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v65i2.1457.

A library of novel benzylic 1,2,3-triazole-4-carboxamides (3a-m) were obtained with acceptable yields via a one-pot procedure. The series of compounds was screened for fungicidal activity and evaluated in vitro against four filamentous fungi and four Candida species. The former consisted of Aspergillus fumigatus, Trichosporon cutaneum, Rhizopus oryzae and Mucor hiemalis, and the latter C. krusei, C. albicans, C. utilis and C. glabrata. According to the in vitro assays, 3d and 3e were the most efficient fungicidal agents (of all the test compounds) against R. oryzae, even better than the reference drug (itraconazole). Thus, 3d and 3e represent important scaffolds that can be modified to increase antifungal activity. Additionally, they are candidates for complementary studies on the inhibition of clinical infections produced by Rhizopus spp. strains.

Keywords : 1,2,3-Triazoles; antifungal activity; 1,3-dipolar cycloaddition; Rhizopus oryzae.
