Gap19 TFA

生物活性

Gap19, a peptide derived from nine amino acids of the Cx43 cytoplasmic loop (CL), is a potent and selective connexin 43 (Cx43) hemichannel blocker. Gap19 inhibits hemichannels caused by preventing intramolecular interactions of the C-terminus (CT) with the CL. Gap19 is not blocking GJ channels or Cx40/pannexin-1 hemichannels. Gap19 has protective effects against myocardial[1][2].

生物活性

Gap 27, a synthetic connexin43 mimetic peptide, is a gap junction inhibitor. Gap 27 possesses conserved sequence homology to a portion of the second extracellular loop leading into the fourth transmembrane connexin segment[1][2].

体外研究
(In Vitro)

Gap 27 causes a remarked decrease in the number of both TRAP-positive mononuclear and multinucleated rat osteoclasts cultured on bovine bone slices. The activity of the remaining osteoclasts is found to be diminished by measuring the percentage of osteoclasts with actin rings of all TRAP-positive cells. In addition, the resorbed area in the treated cultures is greatly diminished[1]. Incubation of the carotid artery with the gap junction inhibitor Gap 27 (500 μM) essentially abolishes the hyperpolarization to acetylcholine but it is without effect on that to levcromakalim. In the guinea-pig isolated internal carotid artery, Gap 27 inhibits acetylcholine-induced, endothelium-dependent hyperpolarizations[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究

Gap 27 (300 μM) inhibits relaxation by 40% in thoracic aorta and the superior mesenteric artery. Gap 27 also attenuates the endothelium-dependent component of the relaxation induced by ATP in thoracic aorta. [3].

[1]

Bone cell cultures are cultured for 48 hours with three different treatments (control, heptanol and Gap 27). After the culture period, bone slices are fixed. The cells are stained for tartrate-resistant acid phosphatase (TRAP). To visualise the nuclei, the cells are incubated with the DNA-binding fluorochrome Hoechst 33258 (1 mg/mL stock diluted 1:800 in PBS) for 10 minutes at room temperature. The numbers of mononuclear and multinucleated TRAP-positive cells on each bone slice are counted[1].

Gap 26 does indeed significantly inhibit our InsP3-triggered intercellular calcium waves, but it did not have any effect on dye coupling through junctional channels as evidenced by the FRAP experiments, despite the fact that connexin 43 was present in the cell lines used[1].
