Lintitript
Based on 1 Customer Validation
Lintitript (SR 27897) is a highly potent, selective, orally active, competitive and non-peptide cholecystokinin (CCK1) receptor antagonist with an EC50 of 6 nM and a Ki of 0.2 nM. Lintitript displays > 33-fold selectivity more selective for CCK1 than CCK2 receptors (EC50 value of 200 nM). Lintitript increases plasma concentration of leptin and food intake as well as plasma concentration of insulin.

CCKAR |
In vitro, Lintitript (SR 27897) is a competitive antagonist of cholecystokinin (CCK)-stimulated amylase release in isolated rat pancreatic acini (pA2 = 7.50) and of CCK-induced guinea pig gall bladder contractions (pA2 = 9.57)[1].
Lintitript produces concentration dependent inhibition of [125I]CCK binding to CCK1 receptor sites in the rat pancreas (IC50 value of 0.58 nM) and also to CCK 2 sites in the guinea pig cortex (IC2 value of 479 nM). Lintitript inhibits [125I]gastrin binding to gastrin receptors. Lintitript (0.5 nM) increases the dissociation constant of CCK for the CCK A receptor (Kd = 1.8 to 7.2 nM) without modifying the maximum number of receptors (Bmax = 1800 to 1770 fmol/mg)[1].
