生物活性

Devazepide (L-364,718) is a potent, competitive, selective and orally active nonpeptide antagonist of cholecystokinin (CCK) receptor, with IC50s of 81 pM, 45 pM and 245 nM for rat pancreatic, bovine gallbladder and guinea pig brain CCK receptors, respectively. Devazepide (L-364,718) is effective for gastrointestinal disorders.

体内研究

Devazepide (oral gavage; 4 mg/kg; twice per day) significantly accelerates cholesterol crystallization and crystal growth to microlithiasis, and the formation of gallstones in mice.
Devazepide (intraperitoneal injection; 0.1-1 mg/kg) has opposite effects on spontaneous locomotor activity, and on caerulein- and apomorphine-induced hypomotility in the mouse.

Animal Model: Male C57BL/6J mice
Dosage: 4 mg/kg
Administration: Oral gavage; 4 mg/kg; twice per day
Result: Increased susceptibility to gallstone formation by impairing gallbladder emptying function.
Disrupted biliary cholesterol metabolism and enhanced intestinal cholesterol absorption in mice.

  • 1.

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in saline)

    Solubility: 5 mg/mL (12.24 mM); Suspended solution; Need ultrasonic

    此方案可获得 5 mg/mL (12.24 mM) 的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    以 1 mL 工作液为例,取 100 μL 50.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中,混合均匀。
