Berninamycin A is a macrocyclic thiopeptide antibiotic first isolated from S. bernensis [1]. Thiopeptides are sulfur containing highly modified macrocyclic antibiotics with a central pyridine/tetrapyridine/dehydropiperidine ring with up to three thiazole substituents on positions 2, 3 and 6. Thiazole antibiotics thiostrepton behaves as proteasome inhibitor in mammalian tumor cells. Berninamycin showed no proteasome inhibitory activity [2]. It has been reported that the action mode of berninamycin on bacterial protein synthesis was related to that of a dissimilar compound thiostrepton. The antibiotics could bind to the complex of 23S RNA with protein L11 and both affect multiple functions of the ribosomal A site [3]. Berninamycin A was involved in inducing the transcriptional activator TipA in Streptomyces [4].
