tetramycin a

Tetramycin (Tetramycin A) is a macrolide antibiotic isolated from Streptomyces hygrospinosus var. Beijingensis. 24-Demethyl-24-ethyltetrin A is a new and highly effective polyene antibiotic with excellent antibacterial activity against a variety of plant pathogens, low toxicity and environmental advantages. The C-4 position of Tetramycin A is a hydrogen atom, while Tetramycin B is a hydroxyl group.

Tetramycin B (4-Hydroxytetramycin A), a polyene macrolide antibiotic and potent antifungal agent, is derived from Streptomyces hygrospinosus var. Beijingensis. Tetramycin B exhibits greater antifungal activity compared to Tetramycin A, primarily due to the critical role of its C-4 hydroxyl in enhancing its biological function.Tetramycin B is effective against various plant pathogenic fungi and has potential agricultural applications.
