LANCOVUTIDE, also known as duramycin, is a 19-amino-acid tetracyclic peptide antibiotic. It is in clinical development for the treatment of cystic fibrosis (CF). It activates an alternative chloride channel in lung epithelial cells by elevating intracellular calcium levels, and may potentially compensate for CF transmembrane conductance regulator deficiency in the airway epithelium and increase the volume of the airway surface liquid.

Lancovutide stimulates Cl- efflux from cystic fibrosis (CF) bronchial epithelial cells (CFBE) in a narrow concentration range (around 1 uM). However, 100 and 250 uM of lancovutide inhibits Cl⁻ efflux from CFBE cells. An inhibitor of the CF transmembrane conductance regulator, gadolinium chloride, inhibited the lancovutide-induced Cl⁻ efflux. No effect on Cl- efflux was observed in non-CF human bronchial epithelial cells (16HBE), human airway submucosal gland cell line, human pancreatic epithelial cells, CF airway submucosal gland epithelial cells, and CF pancreatic cells. The intracellular Ca2+ was increased by 3 uM lancovutide in 16HBE cells but decreased after 1, and 3 uM of lancovutide in CFBE cells.
