Abstract

The species Vatairea guianensis Aubl, has great importance and application in traditional medicine in the treatment of diseases caused by dermatophytic fungi, being a promising species of bioactive molecules, such as antioxidants, antifungal among others. In this context, the objective of this study was to carry out the phytochemical study and to test the cytotoxic activity in tumor strains. The fractionation of the ethanolic extract of the leaves led to the isolation and structural identification of five secondary metabolic agents belonging to the isoflavone class. Two stand out: Vatairenone A (S1) and Vatairenone B (S2), which are new natural products. Structural elucidation was performed using 1D and 2D NMR spectroscopic data, and in comparison with literature data. The substance Lupiwighteona (S3) showed selective cytotoxicity in the breast (MCF-7) and melanoma (SK-MEL-19) lines, with IC50 values 3.971 ± 0.153 and 4.677 ± 0.328 μM, without causing hemolysis in erythrocytes from mice, evaluated by the MTT method in vitro. The results are promising, being the first study of the genus Vatairea with cytotoxic activity of isoflavones from natural products.
