Gene Information

human ... NTSR1(4923)

Application

SR 48692 has been used as a neurotensin high-affinity receptor 1 (NTSR1) antagonist:
  • to explore the function of NTSR1 in glioblastoma (GBM) cells
  • to determine the roles of neurotensin (NT) in the regulation of bile acid (BA) uptake, in vivo
  • to explore the involvement of NTSR1 versus NTSR2 in mice

Biochem/physiol Actions

SR 48692 is a high affinity, orally bioavailable and selective nonpeptide NT1 neurotensin receptor antagonist that antagonizes neurotensin-induced calcium mobilization with a pA2 of 8.13 in HT-29 human colon carcinoma cell line, and blocks the ability of neurotensin to increase GABA levels in the prefrontal cortex.

In a search for nonpeptide agonists for the neurotensin receptor (NTR1), we replaced the adamantyl amino acid moiety found in the antagonist SR48692 (1a) with leucine and related alpha-alkylamino acids found in peptide agonists. When tested in a calcium mobilization

Tridecapeptide neurotensin (NT) acts as a neurotransmitter and/or neuromodulator and plays a role in learning and reinforcement. The central nucleus of amygdala (CeA), which is relatively rich in NT and neurotensin-1 receptors (NTS1), participates in the regulation of memory and

Several lines of evidence suggest a close association between dopamine (DA) and neurotensin (NT) systems in the CNS. Indeed, in the rodent brain, abundant NT-containing fibres are found in DA-rich areas such as the ventral tegmental area and substantia nigra.

In the central nervous system neurotensin (NT) acts as a neurotransmitter and neuromodulator. It was shown that NT has positive reinforcing effects after its direct microinjection into the ventral tegmental area. The central nucleus of amygdala (CeA), part of the
