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.
该发明涉及公式(I)的杂环衍生物,其中R2是氨基,羟基OR4基团或-Y-R5基团,其中R4是氢或C1-4烷基,Y是C1-4烷基烯,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分别选自氢,C1-2烷基,羟基C1-2烷基或烷氧基C1-2烷基,或R7和R8与它们连接的氮原子一起形成饱和的5-6成员杂环环,该环可选择性地包含额外的杂原子;n为一或二,每个R1独立选择自卤素,卤素C1-2烷基,羟基,羟基,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作用,因此在人类或动物治疗方法中有用。该发明还涉及制备这些杂环衍生物的方法,含有它们的药物组成物以及它们在制造用于产生抗血栓或抗凝作用的药物的制剂中的使用。
