New Δ8, 9-pregnene steroids isolated from the extremophile fungus Exophiala oligosperma. Issue 15 (3rd August 2021) - dos Santos, Alef
Abstract: Three pregnene steroids, two of them new, were isolated from ethyl-acetate partition of liquid-cultivation of the extremophyle fungus Exophiala oligosperma, found in a pH 1.5 hydrochloric acid aqueous solution. Spectroscopic studies using NMR and HRMS, allowed the identification of the molecular structures of both Δ 8, 9 -pregnenes, still not described in the literature. Graphical Abstract:
