Larazotideis a peptide which is an orally active zonulin antagonist. Larazotide shows antiviral activity to varicella-zoster virus (VZV) with EC50s of 44.14 and 59.06 μM for strain OKA and 07-1, respectively. Larazotide can be used for the research of celiac disease and infection[1][2].
Danegaptide (GAP-134), a small modified dipeptide, has been identified as a potent and selective second generation gap junction modifier with oral bioavailability.
AT-1002, a 6-mer synthetic peptide[1], is a tight junction regulator and absorption enhancer[2].
Carbenoxolone disodium is the active metabolite of Glycyrrhizic acid (HY-N0184) and the inhibitor of human 11β-HSD and bacterial 3α, 20β-HSD[1]. Carbenoxolone disodium is an uncoupling agent for gap junctions and a potent inhibitor of Vaccinia virus replication[2]. Carbenoxolone disodium is used for the study of peptic, esophageal and oral ulceration and inflammation.
Gap 26 is a connexin mimetic peptide corresponding to the residues 63-75 of connexin 43, which is a gap junction blocker.
Gap 27, connexin43 mimetic peptide, is a gap junction inhibitor.
Rotigaptide (ZP123) is a novel and specific modulator of connexin 43 (Cx43). Rotigaptide prevents the uncoupling of Cx43-mediated gap junction communication and normalizes cell-to-cell communication during acute metabolic stress. Rotigaptide is a potent antiarrhythmic peptide (AAP) with improved stability and has the potential for the investigation of cardiac arrhythmias-specifically atrial fibrillation[1][2].
Tonabersat is a gap-junction modulator.
Meclofenamic acid (Meclofenamate) sodium hydrate is a non-steroidal anti-inflammatory agent. Meclofenamic acid sodium hydrate is a highly selective FTO (fat mass and obesity-associated) enzyme inhibitor. Meclofenamic acid sodium hydrate competes with FTO binding for the m(6)A-containing nucleic acid. Meclofenamic acid sodium hydrate is a non-selective gap-junction blocker. Meclofenamic acid sodium hydrate inhibits hKv2.1 and hKv1.1, with IC50 values of 56.0 and 155.9 μM, respectively[1][2][3][4].
Danegaptide Hydrochloride (GAP-134 Hydrochloride) is a selective modifier of the gap junction protein.
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].
