The invention relates to racemic or optically active 1,3,4-benzotriazepin-5(4H)-one derivatives, a process for the preparation thereof, pharmaceutical compositions comprising the same, to the use of the said compounds for the treatment of diseases and for the preparation of pharmaceutical compositions containing the said compounds as active agent. The new compounds according to the invention correspond to the general formula (I), ##STR1## wherein R.sup.1 represents hydrogen or straight or branched chain C.sub.1-4 alkyl optionally carrying a pyridyl or a phenyl substituent; R.sup.2 stands for cyanoimino; R.sup.3 denotes hydrogen or straight or branched chain C.sub.1-4 alkyl; R.sup.4 stands for C.sub.1-4 alkyl; and the dotted line does not represent a valency bond; or R.sup.2 stands for a group of the formula R.sup.9 R.sup.10 N, wherein R.sup.9 and R.sup.10 are independently hydrogen or straight or branched chain C.sub.1-10 alkyl, or R.sup.9 R.sup.10 N together form a 5- to 7-membered heterocyclic group; or R.sup.9 R.sup.10 N together form a group of the formula N.dbd.C(NR.sup.12 R.sup.13)NH.sub.2, wherein R.sup.12 and R.sup.13 are independently hydrogen or straight or branched chain C.sub.1-10 alkyl, or NR.sup.12 R.sup.13 together form a 5- to 7-membered heterocyclic group; R.sup.4 stands for C.sub.1-4 alkyl; and the dotted line represents a valency bond, consequently substituent R.sup.1 is missing; with the proviso that if R.sup.9 and R.sup.10 are the same, they are other than hydrogen. The 1,3,4-benzotriazepin-5(4H)-one derivatives of the general formula (I) affect the circulatory system and possess antianginal, antihypertensive and peripheral vasodilating effects.
本发明涉及光学活性或外消旋1,3,4-苯并三唑环-5(4H)-酮衍生物、其制备方法、包含该衍生物的制药组合物,以及将该化合物用于治疗疾病和制备含有该化合物作为活性剂的制药组合物。根据本发明,新的化合物符合通式(I),其中R1代表氢或直链或支链C1-4烷基,可选地带有吡啶基或苯基取代基;R2代表氰基亚氨基;R3代表氢或直链或支链C1-4烷基;R4代表C1-4烷基;虚线不代表价键;或者R2代表式R9R10N的基团,其中R9和R10独立地表示氢或直链或支链C1-10烷基,或者R9R10N共同形成5-至7-成员的杂环基团;或者R9R10N共同形成式N=C(NR12R13)NH2的基团,其中R12和R13独立地表示氢或直链或支链C1-10烷基,或者NR12R13共同形成5-至7-成员的杂环基团;R4代表C1-4烷基;虚线表示价键,因此缺少取代基R1;但是,如果R9和R10相同,则它们不是氢。通式(I)的1,3,4-苯并三唑环-5(4H)-酮衍生物影响循环系统,并具有抗心绞痛、降压和周围血管扩张作用。
