  Substituted 6,7-dihydroimidazo[1,2-a]purin-9(4H)-ones

  摘要：

  The synthesis of a series of substituted 6,7-dihydroimidazo[1,2-a]purin-9(4H)-ones is described. Several members of the series exhibit enhanced antiallergic and bronchodilator activity and reduced side effects as compared to theophylline. Structure-activity relationships and metabolic considerations are discussed for the series. Analogues substituted with a 4-(4-chlorobenzyl) moiety, such as 33 and 40, shown an optimal balance of antiallergic and bronchodilator activity and are of particular interest. Compound 33 is significantly more potent than theophylline against both metacholine- and antigen-induced bronchospasms, does not affect spontaneous motor activity, and shows minimal cardiovascular effects in the rat.

  New pharmaceutical compounds of general formula (I): F-(X)q where q is an integer from 1 to 5, preferably 1; -F is chosen among drugs described in the text, -X is chosen among 4 groups -M, -T, -V and -Y as described in the text. The compounds of general formula (I) are nitrate prodrugs which can release nitric oxide in vivo in a controlled and selective way and without hypotensive side effects and for this reason they are useful for the preparation of medicines for prevention and treatment of inflammatory, ischemic, degenerative and proliferative diseases of musculoskeletal, tegumental, respiratory, gastrointestinal, genito-urinary and central nervous systems.

  通式（I）的新药物化合物：F-（X）q，其中q是1到5的整数，最好是1；-F是在文本中描述的药物中选择的，-X是在文本中描述的4个组-M，-T，-V和-Y中选择的。通式（I）的化合物是硝酸盐前药，可以在体内以受控和选择性的方式释放一氧化氮，而不会产生降压副作用，因此它们非常适用于制备用于预防和治疗肌肉骨骼，皮肤，呼吸，消化，泌尿和中枢神经系统的炎症，缺血，退行性和增生性疾病的药物。

  The present disclosure provides a once-daily water-soluble pharmaceutically active formulation for oral administration. In certain embodiments, the composition comprises a water-soluble pharmaceutically active organic compound incorporated into a small particulate, each particulate having a core of the water-soluble pharmaceutically active organic compound or an acceptable salt thereof in reversible association with a pharmaceutically acceptable drug-binding polymer. The core of the composition being surrounded by an insoluble water permeable membrane that is capable of delaying the dissolution of the pharmaceutically active compound therewithin and providing for extended release of the pharmaceutically active compound. In some embodiments, the formulation of the invention are designed to extend release of the pharmaceutically active organic compound for about 3 hours to about 8 hours, thereby enabling preparation of an extended release formulation for any pharmaceutically active compound with a half-life of from about 16 hours to about 21 hours.

  本公开提供了一种用于口服的每日一次水溶性药用活性制剂。在某些实施方案中，该组合物包括掺入小颗粒中的水溶性药用活性有机化合物，每个颗粒都有一个水溶性药用活性有机化合物或其可接受盐的核心，该核心与药学上可接受的药物结合聚合物可逆结合。组合物的核心由不溶性透水膜包围，该膜能够延迟其中的药用活性化合物的溶解，并延长药用活性化合物的释放时间。在某些实施方案中，本发明的制剂可将药用活性有机化合物的释放时间延长约 3 小时至约 8 小时，从而能够制备半衰期为约 16 小时至约 21 小时的任何药用活性化合物的缓释制剂。
