Allgemeine Beschreibung

Chemical structure: tetracycline

Anwendung

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. Wirkung

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.

Sonstige Hinweise

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

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
