  There are disclosed novel oxopyrimidine derivatives of the general formula ##STR1## wherein R.sub.1 and R.sub.2 may be the same or different and are each hydrogen or lower alkyl optionally substituted by lower alkoxy, and R.sub.3 and R.sub.4 may be the same or different and are each phenyl optionally substituted by lower alkyl or halogen, provided that when R.sub.1 and R.sub.2 are both hydrogen, R.sub.3 and R.sub.4 are each substituted phenyl. Pharmaceutical compositions containing these compounds and their use as anticonvulsant, antianxiety and muscle relaxant agents are described.

  本发明涉及一种新型的氧代嘧啶衍生物，其一般式为##STR1##其中R.sub.1和R.sub.2可以相同或不同，分别为氢或低级烷基，可选地被低级烷氧基取代，而R.sub.3和R.sub.4可以相同或不同，分别为苯基，可选地被低级烷基或卤素取代，但当R.sub.1和R.sub.2都为氢时，R.sub.3和R.sub.4为取代的苯基。本发明还描述了含有这些化合物的药物组合物以及它们作为抗癫痫、抗焦虑和肌肉松弛剂的用途。
