一般描述
Chemical structure: tetracycline
应用
Duramycin is used to study chloride secretion by cardial, pancreatic and airway epithelial voltage-gated ion channels. It is used to study cystic fibrosis and as a novel phosphatidylethanolamine-binding molecular probe. It is used to stimulate sodium transport in cultured human colonic epithelia.
生化/生理作用
Duramycin is the smallest known polypeptide since it has only 19 amino acids. It has a defined 3-dimensional binding structure. Duramycin binds phosphatidylethanolamine (PtdE) at a 1:1 ratio with high affinity and exclusive specificity. It enhances chloride secretion in airway epithelium.
其他说明
Keep container tightly closed in a dry and well-ventilated place.

The major anionic phospholipid, phosphatidylserine (PS), and the neutral phospholipid, phosphatidylethanolamine (PE), are largely confined to the inner leaflet of the plasma membrane bilayer in mammalian cells under normal conditions. This asymmetry is lost when cells undergo apoptosis, become activated

The effect of duramycin, a polypeptide antibiotic, on Cl- transport in canine tracheal epithelium mounted in Ussing chambers was studied. Over a narrow concentration range, duramycin increased short-circuit current (Isc) and net Cl- secretion and had no effect on mannitol

The lantibiotic duramycin (Moli1901, Lancovutide) has been suggested as a drug of choice in the treatment for cystic fibrosis (CF). It has been proposed that duramycin may stimulate chloride secretion through Ca²(+) -activated Cl⁻ channels (CaCC). We investigated whether duramycin

Proton transport in microsomal vesicles derived from medullary bone of laying hens was observed to be inhibited in a dose-dependent manner with fusidic acid, 7-chloro-4-nitrobenz-2-oxa-1,3-diatzole (NBD-Cl), duramycin and dicyclohexylcarbodiimide (DCCD). The IC50 values were 570 microM, 4.5 microM, 10 micrograms/ml
