Molarity Calculator

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.

Description

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[1][2][3].

IC50 & Target

EC50: 6 nM (cholecystokinin (CCK1) receptor)[2]; Ki: 0.2 nM (cholecystokinin (CCK1) receptor)[1]
In Vitro

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].

In Vivo

Lintitript (SR 27897; 1 mg/kg, i.v.) completely reverses the CCK-induced amylase secretion. Lintitript also inhibits CCK-induced gastric and gallbladder emptying in mice (ED50s = 3 and 72 μg/kg, respectively). Lintitript is also very active (ED50 = 27 μg/kg p.o.) in the gall bladder emptying protocol with egg yolk as an inducer of endogenous CCK release[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
