Faced with this situation, we decided to contribute to the development of some imidazo [1,2-a] pyridinyl-arylacrylonitriles, as potential new anticandidosics. We proposed the design by molecular hybridization and the synthesis of some imidazo [1,2-a]pyridinyl-arylacrylonitriles following a Knoevenagel condensation reaction between aldehydes and various arylacetonitriles. Furthermore, we carried out the evaluation of the antifungal activities of these hybrid derivatives against Candida albicans, Candida tropicalis and Candida glabrata using the microplate dilution methodology. In the end, imidazo[1,2-a]pyridinyl-arylacrylonitriles turned out to be molecules with strong antifungal activities. The best anticandidosis profile on the three Candida species tested was obtained with the 3-chlorinated compound (5), the MICs of which varied between 357.5 - 0.52 µM. Likewise, the doubly modulated derivative (3c), was particularly illustrated by its good efficacy against Candida tropicalis. These two best compounds can be proposed as the "hit molecules" for further pharmacomodulations in order to have a drug candidate for anticandidosis purpose.
