There will be a HazMat fee per item when shipping a dangerous goods. The HazMat fee will be charged to your UPS/DHL/FedEx collect account or added to the invoice unless the package is shipped via Ground service. Ship by air in Excepted Quantity (each bottle), which is up to 1g/1mL for class 6.1 packing group I or II, and up to 25g/25ml for all other HazMat items.

Lintitript, also known as SR 27897, is a potent, selective, orally active, competitive non-peptide antagonist of the CCK1 receptor, with an EC50 of 6 nM and a Ki of 0.2 nM. Its selectivity for the CCK1 receptor is 33 times greater than that for the CCK2 receptor (EC50 of 200 nM). Lintitript increases plasma concentrations of leptin and food intake as well as insulin[1][2][3]. Lintitript antagonizes CCK-stimulated amylase release in isolated rat pancreatic acini (pA2 = 7.50) and CCK-induced contractions in guinea pig gall bladder (pA2 = 9.57). It inhibits the binding of [125I]CCK to CCK1 receptor sites in rat pancreas (IC50 = 0.58 nM) and to CCK2 sites in guinea pig cortex (IC50 = 479 nM) in a concentration-dependent manner. Lintitript also inhibits the binding of [125I]gastrin to gastrin receptors. At 0.5 nM, Lintitript increases the dissociation constant (Kd) for CCK from the CCK A receptor (Kd = 1.8 to 7.2 nM) without altering the maximum number of receptors (Bmax = 1800 to 1770 fmol/mg)[1].
Lintitript 动物研究
Animal study
Administering Lintitript, i.v., at a dose of 1 mg/kg completely reverses CCK-induced amylase secretion. Lintitript also inhibits CCK-induced gastric and gallbladder emptying in mice, with ED50 values of 3 μg/kg and 72 μg/kg, respectively. Additionally, Lintitript is highly active in gall bladder emptying experiments using egg yolk as an endogenous inducer of CCK release, with an ED50 of 27 μg/kg, p.o.[1].
