Carbenoxolone Maximum Cited Publications 10 Publications Verification	Amyloid-β Gap Junction Protein	Neurological Disease Metabolic Disease
Carbenoxolone is a blood-brain barrier-permeable Pannexin1 inhibitor, gap junction (Gap junction) blocker, and β-amyloid 42 inhibitor. Carbenoxolone modulates voltage-gated currents of wild-type and mutant Panx1, and inhibits stimulus-activated Panx1 channel function. Carbenoxolone interacts with stable residues of β-amyloid 42 peptides, fibrils and oligomers, thereby inhibiting their aggregation. Carbenoxolone alleviates liver fibrosis. Carbenoxolone exerts neuroprotective and nootropic effects. Carbenoxolone can be used in studies related to Alzheimer's disease and liver fibrosis .

ALMB-0168	Gap Junction Protein	Cancer
ALMB-0168 is a Cx43 hemichannel agonist monoclonal antibody. ALMB-0168 activates Cx43 hemichannels to inhibit the growth and migration of osteosarcoma. ALMB-0168 is applicable to relevant research on osteosarcoma .

HY-167983

Cx43 HC-IN-1	Gap Junction Protein	Neurological Disease
Cx43 HC-IN-1 (Compound D4) is a selective and orally active inhibitor of connexin hemichannels (Cx43 HC). Cx43 HC-IN-1 effectively inhibits the hemichannel activity mediated by Cx43/Cx45 in denervated skeletal muscle fibers, significantly increasing the reinnervation rate of muscle fibers by neurons. Cx43 HC-IN-1 reduces neuroinflammation and neuronal overexcitation by inhibiting hemichannels in glial cells in the brain, and alleviates epilepsy in mice. Cx43 HC-IN-1 can be used for research on epilepsy and muscle diseases .
