New 4-anilinopyrimidine derivatives of formula (I): ##STR1## (wherein: R.sup.1 and R.sup.2 are the same or different and each represents a C.sub.1 -C.sub.6 alkyl group or R.sup.1 and R.sup.2 together represent a C.sub.3 -C.sub.5 alkylene group; R.sup.3 represents a hydrogen atom or a C.sub.1 -C.sub.6 alkyl group; n is 0, 1 or 2; and R.sup.4 represents a C.sub.1 -C.sub.6 alkyl group, a C.sub.1 -C.sub.6 alkoxy group, a C.sub.1 -C.sub.6 haloalkyl group, a halogen atom, a nitro group, a C.sub.1 -C.sub.6 alkanesulphonyl group, a cyano group, a carboxy group or a C.sub.2 -C.sub.7 alkoxycarbonyl group and, when n is 2, the two groups represented by R.sup.4 may be the same or different or they may together represent a methylenedioxy group) and pharmaceutically acceptable acid addition salts thereof have been found to have strong antidepressant activity, with low toxicity and very few side-effects. The compounds may be formulated in conventional pharmaceutical compositions for administration by various routes and may be prepared by reacting a 4-halopyrimidine with aniline or an aniline derivative.
公式(I)的新4-苯胺基嘧啶衍生物:##STR1##(其中:R.sup.1和R.sup.2相同或不同,每个代表C.sub.1-C.sub.6烷基或R.sup.1和R.sup.2一起代表C.sub.3-C.sub.5亚烷基基团;R.sup.3代表氢原子或C.sub.1-C.sub.6烷基基团;n为0、1或2;R.sup.4代表C.sub.1-C.sub.6烷基基团、C.sub.1-C.sub.6烷氧基基团、C.sub.1-C.sub.6卤代烷基团、卤原子、硝基、C.sub.1-C.sub.6烷基磺酰基团、氰基、羧基或C.sub.2-C.sub.7烷氧羰基团,当n为2时,由R.sup.4代表的两个基团可以相同或不同,或者它们可以一起代表亚甲二氧基基团),以及其药学上可接受的酸盐,已被发现具有强烈的抗抑郁活性,毒性低,副作用很少。这些化合物可以以传统的制药组成形式制备用于各种途径的给药,并可以通过4-卤代嘧啶与苯胺或苯胺衍生物反应制备。
