Urea derivatives of the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, which are the same or different, each represent a straight- or branched-chain alkyl, alkenyl or alkynyl radical having from 1 to 5 carbon atoms, R.sub.4 and R.sub.5, which are the same or different, each represent a hydrogen atom or a straight- or branched-chain alkyl, alkenyl or alkynyl radical having from 1 to 5 carbon atoms, R.sub.1, R.sub.2 and R.sub.3 being such that: (a) only one of these radicals can represent an alkenyl or alkynyl group having an unsaturated bond in the .alpha.,.beta.-position with respect to the methylurea radical, in this case, each of the other two substituents represents an alkyl radical, (b) the sum of their carbon atoms is never inferior to 4. They are useful as anxiolytic and antiagressive agents.
尿素衍生物的化学式如下:##STR1## 其中R.sub.1、R.sub.2和R.sub.3,它们相同或不同,分别代表具有1至5个碳原子的直链或支链烷基、烯基或炔基基团,R.sub.4和R.sub.5,它们相同或不同,分别代表氢原子或具有1至5个碳原子的直链或支链烷基、烯基或炔基基团,R.sub.1、R.sub.2和R.sub.3的条件为:(a) 这些基团中只有一个可以代表具有与甲基脲基相对的α、β-位置上的不饱和键的烯基或炔基团,在这种情况下,其他两个取代物分别代表烷基基团,(b) 它们的碳原子总数永远不少于4。它们可用作抗焦虑和抗攻击剂。
