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.

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.
