Synthesis and Evaluation of the Antifungal Sensibility of Novel Thienopyridine 1,2,3-Triazole Derivatives

The family of compounds known as azoles are part of most of the antimicrobial drugs used for the treatment of infections. Within this family triazoles have been extensively studied as pharmacophores with very promising results. In this work, four novel trisubstituted 1,2,3-triazole compounds with a thienopyridine moiety (1a,b; 2a,b) were synthesized through an azide-enolate 1,3-dipolar cycloaddition. Their cheminformatic properties were calculated using simulation software available online such as Molinspiration, Molsoft, Osiris Property Explorer, pkCSM, SwissADME, and GUSA. The results provided important information which allowed us to consider the evaluation of the antifungal activity of these novel compounds. Therefore, the antifungal activity of these compounds was evaluated in vitro against four filamentous fungi, including Aspergillus fumigatus ATCC 16907, Trichosporon cutaneum ATCC 28592, Rhizopus oryzae ATCC 10329, and Mucor hiemalis ATCC 8690; as well as six species of yeast from the Candida genus; C. albicans ATCC 10231, C. utilis ATCC 9226, C. tropicalis ATCC 13803, C. parapsilosis ATCC 22019, C. glabrata ATCC 34138 and C. krusei ATCC 14243 The sensibility studies suggest that compounds 1b, 2a and 2b can be considered candidates for complementary biological studies due to the exhibited antifungal activity.
