一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。

资料参考

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].
