Description: Tetramycin B (4-Hydroxytetramycin A), a polyene macrolide antibiotic and potent antifungal agent, is derived from Streptomyces hygrospinosus var. Beijingensis. It exhibits greater antifungal activity compared to Tetramycin A, primarily due to the critical role of its C-4 hydroxyl in enhancing its biological function [1].
