The invention relates to new optically active or racemic 5-phenyl-1,3,4,5-tetrahydro-2H-1,4-benzodiazepin-2-one derivatives of the general formula (I) ##STR1## wherein R.sup.1 stands for hydrogen, halogen, trifluoromethyl or a nitro group; R.sup.2 stands for hydrogen or alkyl having 1 to 6 carbon atoms; R.sup.3 represents a group conventionally attached to the --CH(NH.sub.2)--COOH group of the known optically active or racemic .alpha.-amino-acids, preferably an optionally substituted lower alkyl group; R.sup.4 is hydrogen, chlorocarbonyl or carbamoyl; and X is hydrogen, halogen or trifluoromethyl, with the proviso that if in the racemic compounds R.sup.4 stands for hydrogen R.sup.3 is other than alkyl having 1 to 6 carbon atoms, in which the centers of asymmetry in the 3- and 5-positions have the same absolute configuration, and pharmaceutically acceptable acid addition salts thereof, and a process for their preparation. The new compounds show valuable enzyme inducing activity and can therefore be employed as active ingredients of pharmaceutical compositions, which are also within the scope of the present invention.
该发明涉及一种新的光学活性或消旋5-苯基-1,3,4,5-四氢-2H-1,4-苯二氮杂环己酮衍生物,其一般式为(I)。其中,R.sup.1代表氢、卤素、三氟甲基或硝基;R.sup.2代表氢或具有1至6个碳原子的烷基;R.sup.3代表惯例上连接到已知光学活性或消旋α-氨基酸的--CH(NH.sub.2)--COOH基团的基团,优选为可选择取代的较低烷基基团;R.sup.4为氢、氯代羰基或氨基甲酰基;X为氢、卤素或三氟甲基,但如果在消旋化合物中R.sup.4代表氢,则R.sup.3不是具有1至6个碳原子的烷基,在这种情况下,3-位和5-位的不对称中心具有相同的绝对构型,以及其药学上可接受的酸盐,以及其制备方法。这些新化合物显示出有价值的酶诱导活性,因此可以作为药物组合物的活性成分,该组合物也属于本发明的范围内。
