The invention relates to new 2-(substituted imino)-thiazolidines, a process for the preparation thereof, pharmaceutical compositions comprising the same, the use of the said 2-(substituted imino)thiazolidines for the treatment of diseases and for the preparation of pharmaceutical compositions suitable for the treatment of diseases. The new 2-(substituted imino)-thiazolidine derivatives provided by the present invention correspond to the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 each represent halogen, nitro, C.sub.1-4 alkoxy or C.sub.1-4 alkyl, which latter may optionally carry one or more halogen substituent(s), R.sup.3 and R.sup.4 each represent hydrogen or C.sub.1-4 alkyl, Z denotes oxygen, sulfur or imino, which latter is substituted by a C.sub.1-6 alkyl or a C.sub.1-6 alkenyl group, R.sup.5 stands for hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkylthio or a group or the formula --NH--R, wherein R represents C.sub.1-6 alkyl, aryl, aralkyl or C.sub.1-6 alkenyl optionally carrying a halogen or a di-(C.sub.1-4 alkyl)-amino substituent; or Z and R.sup.5 together stand for a trivalent nitrogen atom, with the proviso that if Z denotes a substituted imino group, R.sup.5 stands for C.sub.1-4 alkylthio, and if R.sup.5 is C.sub.1-4 alkylthio, Z represents a substituted imino, and with the further proviso that if Z denotes sulfur, R.sup.5 is other than hydrogen or C.sub.1-4 alkyl, and possess valuable antianginal and analgesic properties.
本发明涉及新的2-(取代亚氨基)-噻唑烷类化合物、其制备方法、包含该化合物的药物组合物、以及所述2-(取代亚氨基)噻唑烷用于治疗疾病和制备适用于治疗疾病的药物组合物的用途。本发明提供的新的2-(取代亚氨基)-噻唑烷衍生物对应于通式(I),其中R1和R2各自表示卤素、硝基、C1-4烷氧基或C1-4烷基,后者可任选地携带一个或多个卤素取代基,R3和R4各自表示氢或C1-4烷基,Z表示氧、硫或亚氨基,后者被C1-6烷基或C1-6烯基取代,R5表示氢、C1-4烷基、C1-4烷硫基或式--NH--R的基团,其中R表示C1-6烷基、芳基、芳烷基或C1-6烯基,任选地携带卤素或二(C1-4烷基)氨基取代基;或者Z和R5一起表示三价氮原子,但条件是如果Z表示取代的亚氨基基团,则R5表示C1-4烷硫基,如果R5是C1-4烷硫基,则Z表示取代的亚氨基,并且进一步条件是如果Z表示硫,则R5不同于氢或C1-4烷基,并具有有价值的抗心绞痛和镇痛性质。
