Novel 1,4-substituted phenyl piperazine compounds have a pronounced effect upon blood coagulation and are useful in the treatment of thrombotic diseases, especially of the arterial system. They are particularly used to inhibit thrombosis of the coronary or cerebral arteries. Examples of such compounds are 1-phenyl (lower) alkyl-2-phenyl-3-keto-4-di-(lower)alkylamino (lower)alkyl piperazines, 1-phenyl (lower)alkyl-2-keto-3-phenyl-4-di-(lower)alkylamino (lower)alkyl piperazines, 1-phenyl (lower) alkyl-2-phenyl-4-di-alkylamino (lower)alkyl piperazines, 1-phenyl (lower)alkyl-3-phenyl-4-di-(lower)-alkylamino (lower)alkyl piperazines and their pharmaceutically acceptable acid addition salts. The phenyl ring in 1-position may be substituted by halogen, trifluoro (lower)alkyl, lower alkoxy, or phenyl lower alkoxy; the di-(lower)alkylamino (lower)alkyl group in 4-position may be replaced by piperidino (lower)alkyl, morpholino (lower)alkyl, pyrrolidino (lower alkyl, piperazino (lower)alkyl, or the like mononuclear nitrogen-containing heterocyclically substituted (lower)alkyl.
1,4-取代苯基哌嗪化合物对血液凝固具有显著影响,并且在治疗血栓性疾病,尤其是动脉系统的治疗中非常有用。它们特别用于抑制冠状动脉或脑动脉的血栓形成。这类化合物的示例包括1-苯基(较低)烷基-2-苯基-3-酮基-4-双(较低)烷基氨基(较低)烷基哌嗪,1-苯基(较低)烷基-2-酮基-3-苯基-4-双(较低)烷基氨基(较低)烷基哌嗪,1-苯基(较低)烷基-2-苯基-4-双烷基氨基(较低)烷基哌嗪,1-苯基(较低)烷基-3-苯基-4-双(较低)烷基氨基(较低)烷基哌嗪及其药学上可接受的酸盐。1-位置的苯环可能被卤素、三氟(较低)烷基、较低烷氧基或苯基较低烷氧基取代;4-位置的双(较低)烷氨基(较低)烷基基团可能被哌啶(较低)烷基、吗啉(较低)烷基、吡咯啉(较低)烷基、哌嗪(较低)烷基等单核氮杂环取代(较低)烷基所替代。
