The development of antifungal drugs that inhibit lanosterol 14-α-demethylase (CYP51) via non-covalent ligand interactions is a strategy that is gaining importance. A series of novel tetraindol-4-one derivatives with 1- and 2-(2,4-substituted phenyl) side chains were designed and synthesized based on the structure of CYP51 and fluconazole. The antifungal activities of these derivatives against eight human pathogenic filamentous fungi and yeast strains were evaluated in vitro by measuring the minimal inhibitory concentrations. Nearly all tested compounds 8a-g displayed activity against Candida tropicalis, Candida guilliermondii and Candida parapsilosis with a minimum inhibitory concentration (MIC) value until 8 μg mL-1, on the other hand compounds 7a-g showed activity against Aspergillus fumigatus with a MIC value of 31.25 μg mL-1. A molecular modeling study of the binding interactions between compounds 6, 7d, 8g and the active site of MtCYP51 was conducted based on the computational docking results.
