Neuropeptide W-30 (rat) acetate

Neuropeptide W-30 (rat) is an important stress mediator in the central nervous system that modulates the hypothalamus-pituitary-adrenal (HPA) axis and sympathetic outflow. Neuropeptide W-30 (rat) is an endogenous ligand for the two structurally related orphan G-protein-coupled receptors (GPCRs) GPR7 and GPR8. NPW-30 activates and binds to both GPR7 and GPR8 at similar effective doses ^{[1] [2] [3]}.

In Vivo, The i.c.v. administration of Neuropeptide W-30 changes secretion of anterior pituitary hormones, such as prolactin and growth hormone, and behavior, such as feeding and drinking^[1].
