Description
Ipamorelin – Research Capsules for Laboratory Purposes (100 mcg / capsule, 60 count)
Highly selective synthetic pentapeptide agonist of the ghrelin receptor (GHSR-1a) and growth hormone secretagogue in a solid analytical matrix for in vitro research on somatotropic pulsatile signaling, cell proliferation, myoblast differentiation, and receptor kinetics
Overview & Mechanism of Action (In Vitro)
Ipamorelin (Aib-His-D-2-Nal-D-Phe-Lys-NH2) is a third-generation synthetic pentapeptide belonging to the growth hormone secretagogue (GHS) family, characterized by its remarkable selectivity for the GHSR-1a receptor (ghrelin receptor). In cellular biology, molecular endocrinology, and biophysical research, it serves as a primary reference ligand for investigating pure somatotropic axis activation without non-specific off-target endocrine activation:
- High Receptor Selectivity for GHSR-1a: Binds to the Gαq/11-coupled GHSR-1a receptor to activate phospholipase C (PLC), resulting in protein kinase C (PKC) phosphorylation and a transient increase in intracellular calcium (Ca2+), facilitating exocytosis of somatotropic storage granules in pituitary cell models.
- Absence of Non-Specific Corticotropic Cross-Stimulation: Unlike earlier-generation analogs, it exhibits negligible in vitro cross-activation of ACTH, cortisol, or prolactin release pathways, allowing precise isolation of GH-specific signaling events.
- Stimulation of Myoblast Proliferation & Maturation: Enhances downstream insulin-like growth factor 1 (IGF-1) gene expression in primary culture models, promoting Akt/mTOR pathway activation and myotube differentiation in vitro.
- Modulation of Osteoblast Differentiation: Promotes alkaline phosphatase (ALP) expression and type I collagen synthesis in primary osteoblast lines, serving as a model for in vitro bone cell mineralization studies.
