The search for new compounds that present low toxicity and high efficiency in the treatment of different diseases is a challenge. Therefore, this study brings as a novelty the synthesis, biological evaluation and a study of the mechanism of action in serum albumin of trimethoxy-benzylidene-hydrazine-carbothioamide compounds. The in silico results received that all compounds showed good oral availability and could be accepted as potential drug candidates. In cytotoxicity assays, the compounds promoted moderate to low toxicity against macrophage cells (82.90 ± 1.19 to 231.49 ± 1.96 µM) and Hepg2 (91.19 ± 1.09 to 254.64 ± 3.96 µM). In addition to not being hemolytic (< 10%). Regarding in vivo toxicity, they were not toxic in mice at a concentration of 2000 mg/kg (gavage). In in vitro biological assays, the compounds showed low antioxidant activity. The antifungal activity assays showed that the compounds were capable of inhibiting the growth of different strains of yeast. The compounds were also able to inhibit the growth of the parasite L. amazonensis in different promastigote (27.84–40.52 µM) and amastigote (29–49.71 µM) forms. Furthermore, they inhibited the growth of T.cruzi trypomastigotes (28.90–45.24 µM). Assays with albumin generally pleased that the compounds can be transported by these proteins without changes in the macromolecules. In this context, we can conclude that the compounds considered can promote different activities and can contribute to the arsenal of new drug candidate compounds that can act as new antifungal and antiparasitic agents.
