Abstrakt: Dermatomycoses are infections caused by fungi and yeasts and the drug treatment is considered expensive and extensive. Researchers are synthesizing new organic compounds in order to obtain more effective molecules that provide reduced adverse effects. Our research group has synthesized and evaluated the biological activities of aminoalcohol and diamine derivatives, which were considered active against human pathogenic fungi. Therefore, the objective of this study was to evaluate the in vitro antifungal activity of aminoalcohols and diamine derivatives against fungi and yeasts that cause dermatomycoses. The minimum inhibitory concentrations (MICs) and the minimum fungicidal concentration (MFC) of aminoalcohol (1–4) and diamine (5–13) derivatives was determined against Trichophyton mentagrophytes, T. rubrum, Epidermophyton floccosum, and Candida albicans according to protocols from the Clinical and Laboratory Standards Institute. All molecules exhibited fungicidal activity against the evaluated fungal strains, with the MIC and MFC ranging between 0.12 and 1000 μg/mL for filamentous fungi and 0.6 and 1250 μg/mL for yeasts. The best activity was attributed to diamines compared to aminoalcohols, with an emphasis on molecules 6 and 7. These results demonstrate the antifungal potential of the evaluated aminoalcohols and diamines against the four primary fungal species that cause dermatomycoses. [ABSTRACT FROM AUTHOR]
