SR 48692 Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
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
Definition
ChEBI: 2-[[[1-(7-chloro-4-quinolinyl)-5-(2,6-dimethoxyphenyl)-3-pyrazolyl]-oxomethyl]amino]-2-adamantanecarboxylic acid is a N-acyl-amino acid.
Biologische Aktivität
ki: 8.6 nm for ht-29 cellssr 48692 is a nonpeptide neurotensin antagonist.neurotensin is a tridecapeptide and is distributed in both the central and peripheral nervous systems. neurotensin shows a wide spectrum of biological activities resulting in fulfilling a dual function as a neurotransmitter/neuromodulator in the brain and working as a hormone/cellular mediator in peripheral tissues.
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 vitro
sr 48692 was found to inhibit the binding of [3h]- or [125i]-neurotensin to membrane preparations from mouse brains and ht-29 cells. in ht-29 cells, sr 48692 also antagonized the neurotensin-induced mobilization of intracellular calcium, which was consistent with previous findings. moreover, in rat cerebellar slices, sr 48692 could block the cyclic gmp level increase in a dose-dependent manner [1].
in vivo
sr 48692 could antagonize the increase in rat brain mesolimbic dopamine turnover which was induced by the systemically active neurotensin peptide ei. whereas, sr 48692 did not antagonize ei-induced decrease in mouse body temperature and spontaneous locomotor activity [1].
