On the basis of our study on the structure-activity relationships of 1, 3, 7-alkylxanthines and condensed-purines on cAMP-phosphodiesterase 4 (PDE 4) isoenzyme inhibitor, we investigated the synthesis and the inhibitory activity of 3-phenylxanthine and 4-phenyl[i]condensed-purine derivatives. Xanthines and condensed-purines with the phenyl group exhibited potent and selective PDE 4 inhibitory activity.
在研究1,3,7-烷基黄嘌呤和缩合嘌呤对cAMP-磷酸二酯酶4(PDE 4)同工酶抑制剂构效关系的基础上,我们研究了3-苯基黄嘌呤和4-苯基黄嘌呤的合成及其抑制活性。 -苯基[i]缩合嘌呤衍生物。黄嘌呤和带有苯基的稠合嘌呤表现出有效且选择性的 PDE 4 抑制活性。
