The purpose of this study was to develop a method for the stereoselective analysis of thioridazine-2-sulfoxide (THD-2-SO) and thioridazine-5-sulfoxide (THD-5-SO) in culture medium and to study the biotransformation of rac-thioridazine (THD) by some endophytic fungi. The simultaneous resolution of THD-2-SO and THD-5-SO diastereoisomers was performed on a CHIRALPAK® AS column using a mobile phase of hexane:ethanol:methanol (92:6:2, v/v/v) + 0.5%diethylamine; UV detection was carried out at 262 nm. Diethyl ether was used as extractor solvent.The validated method was used to evaluate the biotransformation of THD by 12 endophytic fungi isolated from Tithonia diversifolia, Viguiera arenaria and Viguiera robusta.Among the 12 fungi evaluated, 4 of themdeserve prominence for presenting an evidenced stereoselective biotransformation potential: Phomopsis sp. (TD2) presented greatermono-2-sulfoxidation to the form(S)-(SE) (12.1%);Glomerella cingulata (VA1) presented greater mono-5-sulfoxidation to the forms (S)-(SE) + (R)-(FE) (10.5%); Diaporthe phaseolorum (VR4) presented greater mono-2-sulfoxidation to the forms (S)-(SE) and (R)-(FE) (84.4% and 82.5%, respectively) and Aspergillus fumigatus (VR12) presented greater mono-2-sulfoxidation to the forms (S)-(SE) and (R)-(SE) (31.5% and 34.4%, respectively).
