Spexin Spexin (Neuropeptide Q) is a selective agonist of galanin receptors GAL2 and GAL3, and is a conserved peptide that functions as a neurotransmitter/neuromodulator and endocrine factor. Spexin can function through both central and peripheral actions. Spexin upregulates Beclin 1 to inhibit ferroptosis induced by excessive autophagy, reduces the uptake of long-chain fatty acids by adipocytes, and regulates energy metabolism by increasing lipid oxidation (e.g., reducing the respiratory exchange ratio in rodents). Spexin improves cardiac function in the Doxorubicin hydrochloride (HY-15142)-induced cardiotoxicity model, protects mitochondrial membrane potential, and reduces iron accumulation and lipid peroxidation. Spexin can be used to study obesity and its related metabolic disorders, cardiovascular diseases (e.g., cardioprotection), and side effects of tumor chemotherapy[1][2][3]. Uses: Scientific research. Category: Signaling pathways. Alternative Names: Neuropeptide Q. CAS No. 1370290-58-6. Pack Sizes: 1 mg; 5 mg. Product ID: HY-P1723. MedChemExpress MCE
Spexin Spexin is an endogenous satiety-inducing peptide and a potent galanin receptor 2/3 (GAL2/GAL3) agonist (EC50 = 45.7 and 112.2 nM, respectively), displaying no significant activity at galanin receptor 1. Spexin inhibits long chain fatty acid uptake by adipocytes and decreases food consumption in diet-induced obese mice and rats. It exhibits anxiolytic effects in vivo.
