The invention relates to heterocyclic derivatives of formula (I), wherein R2 is amino, a group OR4 or a group —Y—R5 where R4 is hydrogen or C1-4alkyl, Y is C1-4alkylene, R5 is hydrogen, halo, hydroxy, C1-2alkoxy, C1-2alkoxyC1-2alkoxyC1-4, or a group NR7R8 where R7 and R8 are independently selected from hydrogen, C1-2alkyl, hydroxyC1-2alkyl or alkoxyC1-2alkyl, or R7 and R8 together with the nitrogen atom to which they are attached form a saturated 5-6-membered heterocyclic ring which optionally contains an additional heteroatom; n is one or two and each R1 is independently selected from halo, haloC1-2alkyl, hydroxy, oxo, amino, C1-2alkylamino or di-C1-2dialkylamino; or a pharmaceutically acceptable salt thereof. These compounds possess antithrombotic and anticoagulant properties and are accordingly useful in methods of treatment of humans or animals. The invention also relates to processes for the preparation of the heterocyclic derivatives, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments for use in the production of an antithrombotic or anticoagulant effect.
本发明涉及式(I)的杂环衍生物,其中R2是氨基,OR4基团或-Y-R5基团,其中R4是氢或C1-4烷基,Y是C1-4烷基,R5是氢,卤素,羟基,C1-2烷氧基,C1-2烷氧基C1-2烷氧基C1-4,或NR7R8基团,其中R7和R8独立地选自氢,C1-2烷基,羟基C1-2烷基或烷氧基C1-2烷基,或R7和R8与它们所连接的氮原子一起形成饱和的5-6元杂环环,该环可以选择性地含有一个额外的杂原子;n为一或二,每个R1独立地选自卤素,卤素C1-2烷基,羟基,羰基,氨基,C1-2烷基氨基或二C1-2二烷基氨基;或其药学上可接受的盐。这些化合物具有抗血栓和抗凝血特性,因此可用于人类或动物的治疗方法。本发明还涉及制备杂环衍生物的方法,包含它们的制药组合物以及它们在制造具有抗血栓或抗凝血作用的药物的生产中的使用。
