TAT-Gap19 Chemical Properties,Usage,Production
Uses
TAT-Gap19, a Cx mimetic peptide, is a specific connexin43 hemichannel (Cx43 HC) inhibitor. TAT-Gap19 does not inhibits the corresponding Cx43 GJCs. TAT-Gap19 traverses the blood-brain barrier and alleviate liver fibrosis in mice[1][2][3].
Biological Activity
TAT-Gap19 is a cell penetrant analog of a connexin 43 (Cx43) hemichannels selective blocker Gap19. TAT-Gap19 inhibits TAT-Gap19 in mice brain without affecting gap junction channels.
in vivo
A single injection of TAT-Gap19 (i.v. via the tail vein; 55 mg/kg) produces significant immune signal in the brain 24 h later in 4 months old C57Bl6 male mice[1].
TAT-Gap19 (1 mg/kg/day; an osmotic pump implanted in the peritoneal cavity; Two weeks) shows significantly decreased collagen deposition, as well as lowed amounts of α-SMA-positive cells area in mice subjected to treatment with 100-200 mg thioacetamide (TAA)/kg body weight for eight weeks[2].
