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有显著影响,可用于治疗血栓性疾病,特别是动脉系统的血栓。它们特别用于抑制冠状动脉或脑动脉的血栓形成。这些化合物的例子包括1-苯基(较低)烷基-2-苯基-3-酮基-4-二-(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-4-二-(较低)烷基氨基(较低)烷基哌嗪、1-苯基(较低)烷基-2-苯基-4-二-烷基氨基(较低)烷基哌嗪、1-苯基(较低)烷基-3-苯基-4-二-(较低)烷基氨基(较低)烷基哌嗪及其药学上可接受的酸盐。1-位置的苯环可被卤素、三氟(较低)烷基、低烷氧基或苯基低烷氧基取代;4-位置的二-(较低)烷基氨基(较低)烷基可被哌啶(较低)烷基、吗啉(较低)烷基、吡咯烷(较低)烷基、哌嗪(较低)烷基或类似的单核氮含杂环取代(较低)烷基。
