    • This invention relates to the discovery of substituted analogues of the selective platelet lowering agent anagrelide with reduced potential for cardiovascular side-effects which should lead to improved patient compliance and safety in the treatment of myeloproliferative diseases. More specifically, the present invention relates to certain imidazoquinazoline derivatives which have the general formula shown below where the substituents have the meanings defined in claim (I) and which have utility as platelet lowering agents in humans. The compounds of the present invention function by inhibiting megakaryocytopoeisis and hence the formation of blood platelets.
    • 本发明涉及选择性血小板降低剂阿那格雷的取代类似物的发现,其降低了心血管副作用的可能性,这将导致改善的患者依从性和治疗骨髓增殖性疾病的安全性。 更具体地说,本发明涉及具有如下所示通式的某些咪唑并喹唑啉衍生物,其中取代基具有权利要求(I)中定义的含义并且在人类中可用作血小板降低剂。 本发明的化合物通过抑制巨核细胞生成并因此形成血小板起作用。

    • This invention relates to the discovery of prodrugs of substituted analogues of the selective platelet lowering agent anagrelide which have reduced potential for cardiovascular side-effects and which should therefore lead to improved patient compliance and safety in the treatment of myeloproliferative diseases. More specifically, the present invention relates to prodrugs of certain imidazoquinazoline derivatives which have the general formula (I) shown below wherein the substituents have the meanings defined in claim 1 and which have utility as platelet lowering agents in humans. The compounds of the present invention function by inhibiting the formation of blood platelets.
    • 本发明涉及选择性血小板降低剂阿那格雷的取代类似物的前体药物的发现,其降低了心血管副作用的可能性并且因此应该导致改善的患者依从性和治疗骨髓增殖性疾病的安全性。 更具体地说,本发明涉及具有如下所示的通式(I)的某些咪唑并喹唑啉衍生物的前体药物,其中取代基具有权利要求1中定义的含义并且可用作人类血小板降低剂。 本发明的化合物通过抑制血小板的形成起作用。
