SSTR4agonist-1 (Compound 47) is a selective agonist of the somatostatin receptor 4 (SSTR4), with an EC50 of 4.7 nM. It has a half-life of over 130 minutes in human liver microsomes.

SSTR4 agonist5 (Compound 5) is an orally active agonist of the somatostatin receptor 4 (SSTR4) with an EC50 of 0.228 nM. It demonstrates good stability in human/rat liver microsomes and can inhibit mechanical hyperalgesia in rat models.

SSTR4 agonist 2 is a potent somatostatin receptor subtype 4 (SSTR4) agonist with potential applications in research on SSTR4-related medical disorders. The SSTR4 pathway inhibits nociceptive and inflammatory processes [1].

SSTR4 agonist 4 is a potent SSTR4 agonist with potential applications in pain research. SSTR4 agonists demonstrate efficacy in rodent models of pain associated with acute and chronic anti-peripheral nociceptive and anti-inflammatory activity. SSTR4 is expressed at relatively high levels in the hippocampus and neocortex, regions involved in memory and learning, and in Alzheimer's disease pathology [1].

SSTR4 agonist 3 is a potent compound that activates the SSTR4 receptor, which is highly expressed in the hippocampus and neocortex—regions associated with memory, learning, and Alzheimer's disease pathology. SSTR4 agonists demonstrate strong efficacy in rodent models of both acute and chronic pain by reducing peripheral nociception and inflammation. Considering its potential application in pain research, SSTR4 agonist 3 is of interest [1].
