  Cholecystokinin peptidomimetics as selective CCK-B antagonists: Design, synthesis, and in vitro and in vivo biochemical properties

  摘要：

  Antagonists of cholecystokinin-B (CCK-B) receptors have been shown to alleviate CCK4-induced panic attacks in humans and to potentiate opioid effects in animals. The clinical use of these compounds is critically dependent on their ability to cross the blood-brain barrier. In order to improve this property, new, peptoid-derived CCK-B antagonists, endowed with high affinity, selectivity, and increased lipophilicity have been developed. The affinity and selectivity of these compounds have been characterized in vitro and in vivo using guinea pig, rat, and mouse. Most of these compounds proved to be selective for the CCK-B receptor, the most potent analog, N-[N-[(2-adamantyloxy)carbonyl]-D-alpha-methyltryptophanyl]-N-[2-(4-chlorophenyl)ethyl]glycine (26A), having a K(i) value of 6.1 nM for guinea pig cortex membranes in vitro and a good selectivity ratio (K(i) CCK-A/K(i) CCK-B = 174). Furthermore, the in vivo affinity of 26A for mouse brain CCK-B receptors, following intracerebroventricular injection at different concentrations, was found to be 10 nmol. Using competition experiments with the specific CCK-B ligand [H-3]pBC 264, compound 26A was shown to cross the blood-brain barrier (0.2%) after intraperitoneal administration in mice. This compound is therefore an interesting pharmacological tool to further elucidate the physiopathological role of endogenous CCK.

  摘要：

  描述了新型3-苯并ze庚因系列的5-HT 2C激动剂的合成和SAR。在体外，化合物7d（lorcaserin，APD356）被鉴定为更有效和选择性的化合物之一（在功能测定中，通过[[3] H]磷酸肌醇周转率测定的pEC50值：5-HT2C = 8.1; 5-HT2A = 6.8; 5- HT2B = 6.1），并且在口服后在急性体内大鼠食物摄入模型中有效（在6 h时的ED50 = 18 mg / kg）。Lorcaserin在大鼠单剂量药代动力学研究中进一步表征（t1 / 2 = 3.7小时； F = 86％），以及在生长的Sprague-Dawley大鼠中28天的体重增加模型（在60℃时观察到体重增加减少8.5％） 36 mg / kg出价）。选择洛卡西林在肥胖症的临床试验中进行进一步评估。
