Fluorescent Talarolactones from Talaromyces sp

Wei-Hua Yuan et al. Chem Biodivers. 2022 Oct.

Abstract

(+)-Talarolactone C (1), Talarolactone A (2), Talarolactone B (3, sulfoxide derivative), and Talarolactone D (4, sulfone derivative) were isolated from Talaromyces sp. which was cultured in rice medium with sodium butyrate. The structures of talarolactone analogs above were characterized by a combination of spectroscopic, X-ray crystallographic, and computational methods. These talarolactones and Talarolactone A sodium (5) with the same carbon skeleton showed different fluorescence characteristics.

Keywords: Talarolactone; Talaromyces; fluorescence; structure elucidation.
