  新型三嗪作为有效的和选择性的磷酸二酯酶10A抑制剂

  摘要：

  据报道鉴定了抑制PDE10A的高效和口服活性三嗪。新的类似物对PDE10A表现出低纳摩尔效价，对PDE家族的所有其他成员表现出高选择性，并显示出所需的类药物特性。采用基于结构的药物设计方法，我们通过系统地探索PDE10A配体结合口袋的各个子区域，研究了PDE10A抑制剂对其他已知PDE同工型的选择性。对新合成化合物的ADME和药代动力学特性的系统评估已导致设计出具有良好脑通透性和理想药物动力学（t 1/2，生物利用度，清除率）的类药物候选物。化合物66对PDE10A具有很强的效力（IC 50  = 1.4 nM），对其他PDE具有很高的选择性（> 200x），并且在精神病动物模型中有效。MK-801诱导的机能亢进（MED = 0.1 mg / kg）和条件回避反应（CAR; ID 50  = 0.2 mg / kg）的逆转。

  Derivatization efforts were continued to discover backups for a potent selective PPARγ modulator, DS-6930. In this Letter, the replacement of 2-pyridine ring in DS-6930 with 3- or 4-pyridyl group is reported. As the introduction of substituents on the pyridine ring did not provide potent partial agonists, modifications of benzimidazole ring were explored to discover potent intermediate agonists. 4′-Alkoxy

  structure of the benzene moiety of S-(2-(acylamino)phenyl) 2,2-dimethylpropanethioates and CETP inhibitory activity were performed. Substituents on the benzene moiety influenced CETP inhibitory activity in a type and position dependent manner, and electron-withdrawing groups at the 4- or 5-position increased the activity. The most potent compound showed 50% inhibition of CETP activity in human plasma at
