The invention relates to derivatives of N,N′-substituted piperazines of the general formula (I):
where R1 and R2 denote linear or branched (C1-C4)alkyl, linear or branched (C1-C4)alkoxy, CH3C(═O)O or halogen; n=1-5; m=0-3; Z denotes CH2, C═O or SO2; X denotes C(═NH)NH2, C(═NH)NHC(═NH)NH2 or CH2(CHR3)pCH2SO3H, where R3 denotes H, OH, CH3C(═O)O or HOSO2O and p=0-1; and G denotes low-molecular-weight organic or mineral acid, sodium, potassium or ammonium cations, or water. Said derivatives have antiaggregant, anticoagulant and vasodilatory properties. The invention further relates to a method for producing said derivatives by reacting N-substituted piperazines either with carboxamide amidating agents or salts thereof, or with haloalkyl sulfonic acids or salts thereof in organic solvents or in water in the presence of bases. The compounds may be used for the prophylaxis and treatment of disorders of the hemostatic system.
本发明涉及一般式(I)的N,N'-取代哌嗪衍生物,其中R1和R2表示线性或支链(C1-C4)烷基,线性或支链(C1-C4)烷氧基,CH3C(═O)O或卤素;n=1-5;m=0-3;Z表示CH2,C═O或SO2;X表示C(═NH)NH2,C(═NH)NHC(═NH)NH2或CH2(CHR3)pCH2SO3H,其中R3表示H,OH,CH3C(═O)O或HOSO2O,p=0-1;G表示低分子量有机或矿物酸,钠,钾或铵阳离子,或水。这些衍生物具有抗聚集、抗凝和扩血管的特性。本发明还涉及一种通过在有机溶剂或水中存在碱的情况下将N-取代哌嗪与羧酰胺酰化剂或其盐,或卤代烷磺酸或其盐反应来制备这些衍生物的方法。这些化合物可用于预防和治疗止血系统疾病。
