Morpholino-substituted pyridopyrimidine, quinolone, and benzopyranone derivatives inhibit phosphoinositide (PI) 3-kinase, an enzyme that regulates platelet-adhesion processes. As a consequence, the compounds in question have anti-thrombotic activity, as well as other pharmaceutical properties. The compounds claimed are represented by formula (I), (II) and (III). PI 3-kinase generates 3-phosphorylated PI second messengers which stimulate platelet adhesion under blood-flow conditions. Because platelet adhesion is a necessary step in the formation of a thrombus, inhibition by these compounds of PI 3-kinase under such conditions inhibits or prevents thrombus formation. The compounds are useful in treating PI 3-kinase-dependent conditions including cardiovascular diseases such as coronary artery occlusion, stroke, acute coronary syndrome, acute myocardial infarction, vascular restenosis, atherosclerosis, and unstable angina; respiratory diseases such as asthma, chronic obstructive pulmonary diseases (COPD), and bronchitis; inflammatory disorders, neoplasms including cancers such as glioma, prostate cancer, small cell lung cancer, and breast cancer, and diseases linked to disordered white blood cell function, such as autoimmune and inflammatory diseases.
Morpholino取代的吡啶并[3,4-d]吡嗪、喹诺酮和苯并吡喃衍生物抑制磷脂酰肌醇(PI)3-激酶,该酶调节血小板粘附过程。因此,所述化合物具有抗血栓活性,以及其他药物特性。所声称的化合物由公式(I)、(II)和(III)表示。PI 3-激酶产生3-磷酸化的PI第二信使,在血流条件下刺激血小板粘附。由于血小板粘附是形成血栓的必要步骤,这些化合物在此类条件下抑制PI 3-激酶会抑制或预防血栓形成。这些化合物可用于治疗PI 3-激酶依赖性疾病,包括心血管疾病,如冠状动脉闭塞、中风、急性冠状动脉综合征、急性心肌梗死、血管再狭窄、动脉粥样硬化和不稳定性心绞痛;呼吸系统疾病,如哮喘、慢性阻塞性肺疾病(COPD)和支气管炎;炎症性疾病、肿瘤包括胶质瘤、前列腺癌、小细胞肺癌和乳腺癌,以及与白细胞功能紊乱相关的疾病,如自身免疫和炎症性疾病。
