SR 142948 TFA
Based on 1 publication(s) in Google Scholar
SR 142948 TFA is an orally active and selective non-peptide neurotensin receptor (NT) antagonist with IC50s of 1.19 nM, 0.32 nM, 3.96 nM in h-NTR1-CHO cells, HT-29 cells, and adult rat brain, respectively. SR 142948 TFA antagonizes NT-induced inositol monophosphate formation in HT-29 cells with an IC50 of 3.9 nM. SR 142948 TFA blocks hypothermia, analgesia and steering behavior induced by NT in vivo. SR 142948 TFA shows blood-brain permeability and can be used in study of psychiatric disorders.

Biological Activity
Description
In Vitro
SR 142948 (1 µM; 90 min) TFA inhibits expression of c-fos and krox24 in CHO-hNT1-R cells[1].
SR 142948 (0-1 µM; 1 h) TFA exhibits good antagonistic activity by inhibiting [125I-Tyr3]NT binds to h-NTR1-CHO and HT 29 cell membranes, with IC50s of 1.19 and 0.32 nM, respectively[2].
SR 142948 (0-1 µM; 30 min) TFA antagonizes production of IP1 stimulated by NT both in h-NTR1-CHO and HT 29 cells, in a concentration-dependent manner[2].
SR 142948 (1, 10 nM; 60-80 s) TFA antagonizes intracellular calcium mobilization stimulated by NT in h-NTR1-CHO cells[2].

In Vivo
SR 142948 (0.01, 0.03, 0.3 mg/kg; i.p.; single) TFA prevents the enhancement of ACh release produced by NT (100 nM), in a dose-dependent manner[2].
SR 142948 (0-10 mg/kg; p.o.; single) TFA partially but significantly blocks NT-induced hypothermia (53% at 2 mg/kg in rats and 54% at 4 mg/kg in mice)[2].
