    • 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; andX 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.
    • 本发明涉及通式(I)的新的光学活性或外消旋的5-苯基-1,3,4,5-四氢-2H-1,4-苯并二氮杂-2-酮衍生物,其中R 1 代表氢,卤素,三氟甲基或硝基; R2代表氢或具有1至6个碳原子的烷基; R3表示通常与已知光学活性或外消旋的α-氨基酸的-CH(NH 2)-COOH基团连接的基团,优选任选取代的低级烷基; R4是氢,氯代羰基或氨基甲酰基; 并且X是氢,卤素或三氟甲基,条件是如果在外消旋化合物中R4代表氢,R3不是具有1至6个碳原子的烷基,其中3-和5-位的不对称中心具有 相同的绝对构型及其药学上可接受的酸加成盐及其制备方法。 新化合物显示有价值的酶诱导活性,因此可用作药物组合物的活性成分,其也在本发明的范围内。
