Neurotensin-related hexapeptide exists in retinal ganglion cells and in their central projections in pigeons and may be utilized as a neuroactive substance by the central terminals of numerous retinal ganglion cells in birds.
[Lys8, Lys9]-Neurotensin (8-13) (JMV438) is a Neurotensin analog that elicits analgesic effects by activating the G protein-coupled receptors NTS1 and NTS2. The compound has K i values of 0.33 nM and 0.95 nM for hNTS1 and hNTS2 receptors, respectively.
[D-Trp11]-Neurotensin is a compound that functions as a selective antagonist of Neurotensin (NT) in perfused rat hearts, while exhibiting full agonist properties in guinea pig atria and rat stomach strips. Additionally, this compound can inhibit hypotension induced by NT.
