Quinolinone and pyridopyrimidinone inhibitors of DNA-dependent protein kinase
摘要:
以选定的芳基和杂芳基为取代基合成了 8-取代的 2-吗啉-4-基-喹啉-4-酮和 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮,作为 DNA 依赖性蛋白激酶的潜在抑制剂。在制备 8-取代的 2-吗啉-4-基-喹啉-4-酮的过程中,采用了铃木交叉偶联法的多重平行方法。为此,需要 8-溴-2-吗啉-4-基-喹啉-4-酮作为中间体。这种化合物是通过调整文献路线获得的,在该路线中,(2-溴苯胺基)-吗啉-4-基-5-亚甲基-2,2-二甲基[1,3]二噁烷-4,6-二酮的热环缩合得到 8-溴-2-吗啉-4-基-喹啉-4-酮。以 9-羟基-2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮 O-三氟甲磺酸酯为中间体,利用铃木交叉偶联法制备了 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮。8-取代的 2-吗啉-4-基-喹啉-4-酮和 9-取代的 2-吗啉-4-基-吡啶并[1,2-a]嘧啶-4-酮都是 DNA 依赖性蛋白激酶的抑制剂。当取代基为二苯并噻吩-4-基、二苯并呋喃-4-基或二苯并噻吩-3-基时,观察到的 IC50 值在纳摩尔范围内。有趣的是,吡啶嘧啶酮和喹啉酮与之前报道的相应的 8-取代 2-吗啉-4-基-苯并吡喃-4-酮基本等效(I. R. Hardcastle、X. Cockcroft、N. J. Curtin、M. Desage El-Murr、J. J. J. Leahy、M. Stockley、B. T. Golding、L. Rigoreau、C. Richardson、G. C. M. Smith 和 R. J. Griffin,J. Med.Chem.,2005,48,7829-7846)。

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.
