Lanreotide acetate(CAT: I016738) is a synthetic cyclic octapeptide and long-acting somatostatin analog that binds with high affinity to somatostatin receptors (particularly SSTR2 and SSTR5). It inhibits growth hormone (GH) and insulin-like growth factor-1 (IGF-1) secretion, making it effective in the treatment of acromegaly and neuroendocrine tumors. Lanreotide also reduces gastrointestinal hormone release, intestinal motility, and splanchnic blood flow. As a stable acetate salt, it provides enhanced solubility and formulation properties. Lanreotide acetate is widely used in endocrinology and oncology research to explore somatostatin receptor signaling, hormone regulation, tumor growth suppression, and therapeutic strategies for hormone-related disorders.
