Endomorphin 2 TFA, displays reasonable affinities for kappa3 binding sites, with Ki value between 20 and 30 nM. a high affinity, highly selective agonist of the μ-opioid receptor,
Relamorelin (RM-131) acetate is a pentapeptide ghrelin analog that acts as a selective agonist for the ghrelin/growth hormone secretagogue receptor (GHSR). It exhibits a high affinity for the GHS-1a receptor, with a Ki value of 0.42 nM. Notably, Relamorelin acetate can cross the blood-brain barrier and target the central nervous system. This compound effectively increases growth hormone levels and promotes faster gastric emptying. Due to these properties, Relamorelin acetate holds promise for its potential applications in research related to cachexia, gastroparesis, and gastric/intestinal dysmobility disorders [4] [5].
Alexamorelin Met 1 is one of the metabolites of alexamorelin. The heptapeptide Ala-His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 (Alexamorelin) is a synthetic molecule which inhibits growth hormone secretagogue binding in vitro.
Hemorphin-7 binds to the angiotensin IV receptor, triggering multiple effects including cellular proliferation and memory enhancement. Hemorphins are endogenous peptides belonging to the family of atypical opioid peptides released from hydrolyzed hemoglob
