1-5-b-Neoendorphin (human) (9CI)|Leu-enkephalin is an endogenous opioid peptide that acts as an agonist at -opioid receptors ( ORs) and -opioid receptors ( ORs). Met-enkephalin exhibits neuromodulatory, antinociceptive/analgesic, and gastrointestinal motility modulating activities. Like other endogenous opioids, leu-enkephalin modulates expression of opioid receptors and plays a role in reward/reinforcement signaling. Leu-enkephalin increases pain thresholds in vivo and inhibits gastrointestinal muscle contractility in other animal models, inhibiting motility and gastric emptying.|C28H37N5O7|555.62|White to off white powder|+4°C|
