Biological Activity
Potent, metabolically stable neurotensin receptor agonist peptide (IC50 = 0.15 nM for inhibition of [125I]-NT binding to neonatal mouse brain; EC50 = 1.9 nM for contraction of guinea pig ileum). Produces long-lasting hypothermic, neuroprotective and analgesic effects in mice following central administration in vivo.
