Berninamycin D

Berninamycin D is an antibiotic discovered in 1994 isolated from a strain of Streptomyces as a minor analogue of berninamycin A. Berninamycin D is a macrocyclic "peptide" comprising atypical amino acids linked to thiazole and oxazoles but does not contain the didehydroalaninyl side chain present in other members of this class. The implications of the absence of this side chain are unknown and lack of availability has prevented a fuller investigation of this metabolite. , , DMSO and DMF, partially soluble in methanol and ethanol while poorly soluble in water
