Deuterated 2-alkylaminoacetamide compounds are described having the alpha carbon of the alkyl side chain of the compounds substituted by one or two deuterium atoms. These compounds have pharmacokinetic properties which enable treatment of CNS diseases with lower toxic effects. These compounds are also useful in evaluating the metabolic fate of non-deuterated counterpart compounds. Of particular interest are compounds of Formula I: ##STR1## wherein X is deutero or hydrido; wherein R.sup.1 is selected from alkyl and aralkenyl; wherein each of R.sup.2 and R.sup.3 is independently selected from hydrido and alkyl; wherein each of R.sup.1, R.sup.2 and R.sup.3 having a substitutable position may be substituted with one or more halo radicals; or a pharmaceutically-acceptable salt thereof.
描述了具有α碳原子被一个或两个
氘原子取代的脱
氘2-烷基
氨基乙酰胺化合物。这些化合物具有药代动力学特性,可以以更低的毒性效果治疗中枢神经系统疾病。这些化合物还可用于评估非脱
氘对应物化合物的代谢命运。特别感兴趣的是具有以下式I的化合物:##STR1## 其中X是
氘或氢;其中R.sup.1选自烷基和芳基烯基;其中R.sup.2和R.sup.3中的每个独立选择自氢和烷基;其中具有可替代位置的R.sup.1、R.sup.2和R.sup.3中的每一个都可以被一个或多个卤基取代;或其药用盐。
