Isolation and characterization of antimicrobial constituents from a terrestrial Streptomyces sp.: A preliminary result

Five phenolic derivatives, namely 2-methoxybenzene-1,3-diol (1), 2,3-dihydroxy-benzamide (2), benadrostin (4), 2,3-dihydroxy-benzoicacid (5) and tyrosol (6) were isolated from the terrestrial Streptomyces sp. Ank75. Three of them are new natural products. A further new antifungal is an azoxy derivative 3. All structures were elucidated based on spectroscopic and MS data and will be discussed here
