General description

Chemical structure: tetracycline

Application

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.

Biochem/physiol Actions

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.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

Duramycin is a small tetracyclic peptide which binds specifically to ethanolamine phospholipids (PE). In this study, we used lipid monolayers consisting of 1-palmitoyl-2-oleoyl phosphatidylethanolamine (POPE) and various phosphatidylcholines (PC) to investigate the effect of duramycin on the organization of lipids

Duramycin is a 19-amino-acid tetracyclic lantibiotic closely related to cinnamycin (Ro09-0198), which is known to bind phosphatidylethanolamine (PE). The lipid specificity of duramycin was not established. The present study indicates that both duramycin and cinnamycin exclusively bind to ethanolamine phospholipids

Duramycin increases short-circuit current (Isc) and net Cl- secretion in tracheal epithelium. We measured the intracellular free calcium ([Ca2+]i) response to duramycin using Indo-1 and bovine and canine tracheal cell suspensions, and the effect of an intracellular calcium chelator, BAPTA

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

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
