hc-3

HC-3 inhibits ChoK by binding at the conserved hydrophobic groove on the C-terminal lobe.

HC-056456 (3,4-Bis(2-thienoyl)-1,2,5-oxadiazole-N-oxide) is a CatSper channel modulator.

TAT-Gap19 TFA, a Cx mimetic peptide and specific connexin43 hemichannel (Cx43 HC) inhibitor, does not inhibit corresponding Cx43 gap junction channels (GJCs). It crosses the blood-brain barrier and has shown efficacy in alleviating liver fibrosis in mice [1] [2] [3].

TAT-Gap19 acetate is a specific inhibitor of connexin43 hemichannel (Cx43 HC). TAT-Gap19 acetate traverses the blood-brain barrier and alleviates liver fibrosis in mice. TAT-Gap19 acetate does not inhibit the corresponding Cx43 GJCs.

Cx43 hemichannel blocker (IC50 ~7 μM). No significant affinity for gap junctions or Panx1 channels. N-terminal transactivator of transcription (TAT) motif promotes membrane permeability and increases inhibitory effect of Gap19. Active in vivo. Brain penet
