catestatin

Non-competitive nicotinic cholinergic antagonist; selectively inhibits nicotinic-stimulated catecholamine secretion from chromaffin cells and noradrenergic neurons (IC50 ~ 200 nM). Blocks nicotinic-induced cationic signaling (IC50 ~ 200 - 250 nM) and inhi

Catestatin TFA, a 21-amino acid residue peptide, exhibits both cationic and hydrophobic properties. This endogenous peptide plays a crucial role in regulating cardiac function and blood pressure. It functions as a non-competitive nicotinic antagonist by interacting with nicotinic acetylcholine receptors (nAChRs) to inhibit catecholamine release.

Catestatin human, a peptide that inhibits catecholamine release, plays a role in cardiovascular protection due to its antihypertensive and angiogenic properties. It can also be employed in research on inflammatory diseases [1].

Catestatin (rat) (Rat chromogranin A367–387) is a potent, reversible, non-competitive, and non-cooperative nicotinic acetylcholine receptor (nAChR) antagonist derived from chromogranin A (A367-387). It inhibits norepinephrine release in rat PC12 pheochromocytoma cells (IC50= 1.2 μM) and blocks norepinephrine release desensitization (IC50= 0.62 μM). Catestatin (rat) exerts anti-adrenergic effects via the endothelial PI3K-AKT-eNOS pathway in rat papillary muscle and isolated cardiomyocytes. In ischemia/reperfusion myocardial cells, it maintains mitochondrial membrane potential and increases phosphorylation of AKT at S473, GSK3β at S9, PLB at T17, and eNOS at S1179. Additionally, Catestatin (rat) reverses 22Na+ uptake desensitization. This compound is useful for studying the regulation of nicotinic cholinergic receptors and catecholamine release control mechanisms.

Catestatin (mouse) is an antimicrobial peptide that effectively activates Mrgprb2 with an EC50 value of 59.73 μM. It significantly enhances the clearance of methicillin-resistant Staphylococcus aureus (MRSA) in infected wounds and inhibits the inflammatory immune response caused by MRSA infections.

Catestatin acetate is a non-competitive antagonist of nAChR and inhibits catecholamine release. Catestatin acetate regulates cardiac function and blood pressure.

S 24795 (Catestatin acetate(142211-96-9 free base)) is an α7 nAChR partial agonist. S 24795 improves mnemonic function in aged mice and can be used in studies about aging-related memory disturbances.
