An analgesic and an exocrine and endocrine signaling mediator, predominantly synthesized in the submandibular gland and prostate of adult rats. Sialorphin prevents spinal and renal NEP from breaking down substance P and Met-enkephalin in vitro. It inhibits the breakdown of substance P with an IC50 of 0.4-1 µM and behaves as a competitive inhibitor. Elicits potent antinociceptive responses in two behavioral rat models of injury-induced acute and tonic pain. Has a role in erectile function most likely through a mechanism that involves relaxation of corporal smooth muscle tissue.
