Berninamycin A is an antibiotic discovered in 1976 from a strain of Streptomyces. Berninamycin A is a macrocyclic 'peptide' comprising atypical amino acids linked to thiazole and oxazoles. Berninamycin A is closely related to siomycin, a recently discovered inhibitor of oncogenic transcription factor, FoxM1.
Berninamycin A is soluble in DMF and DMSO.
