兰考韦泰是具有确定的3维结合结构的多肽抗生素。杜拉霉素是已知的最小的多肽，仅具有19个氨基酸。兰考韦泰增强气道上皮中的氯化物分泌。兰考韦泰用于研究囊性纤维化，并用作新型磷脂酰乙醇胺结合分子探针。兰考韦泰也被称为Lancovutide和Leucopeptin。 Duramycin is a polypeptide antibiotic with a defined 3-dimensional binding structure. Duramycin is the smallest known polypeptide, with only 19 amino acids. Duramycin enhances chloride secretion in airway epithelium. Duramycin is used in studies of cystic fibrosis and as a novel phosphatidylethanolamine-binding molecular probe. Duramycin is also known as Lancovutide, and Leucopeptin.
