  拟精神病药物的硫类似物。3.甲斯卡灵及其单硫代类似物的乙基同系物。

  摘要：

  合成了麦斯卡林单，二和三乙氧基同系物的所有可能的单硫代类似物，并在人体中进行了药理学评估。在乙胺链对位的环位置进行的修饰，无论是被硫原子，更长的烷基链，还是两者都被修饰，都会导致中枢神经系统活性高的化合物。还合成了4-正丙氧基和4-正丁氧基同系物及其相应的4-硫代类似物，并进行了药理学评价。丙基同系物保留了高效力，但是丁基（具有或不具有硫原子）导致活性降低。间乙基或间硫代类似物保留一些中心作用，但是二乙氧基，尤其是三乙氧基同系物作为拟精神病药物相对无效。

  A series of 2-methoxyacylhydrazones were optimized to yield compounds with high affinity for PDE10A. Several compounds demonstrated efficacy in animal models of schizophrenia, including conditioned avoidance response and a pro-psychotic phencyclidine hyperactivity model. (C) 2012 Elsevier Ltd.
