Functional Description

| PEP-ETI001 | Highly selective SSTR2 receptor agonist that inhibits hormone secretion and tumor proliferation, applied in neuroendocrine tumor research | Etimumotide is an optimized somatostatin analog. D-2-naphthylalanine substitution and disulfide cyclization significantly enhance SSTR2 receptor affinity and subtype selectivity, with extremely low affinity to SSTR1, SSTR3, SSTR4 and SSTR5, and fewer side effects. SSTR2 activation inhibits adenylate cyclase to reduce cAMP levels, suppresses secretion of multiple hormones such as growth hormone, insulin and glucagon, and simultaneously inhibits tumor cell proliferation and constricts tumor blood vessels. With superior receptor selectivity to first-generation analogs like octreotide, it serves as a core tool molecule for neuroendocrine tumor, pituitary adenoma and hormone secretion mechanism research, as well as subtype-selective drug development. | Neuroendocrine tumor research,Pituitary adenoma research,Hormone secretion regulation research,Somatostatin pathway research,Subtype-selective drug development,Tumor proliferation inhibition research | Somatostatin Receptor 2 (SSTR2); cAMP/PKA signaling pathway; Hormone secretion regulatory pathway; Tumor proliferation inhibition pathway |
