In order to develop novel and orally active phosphodiesterase (PDE) 4 inhibitors, random screening was performed using our chemical library to find YM-10335 possessing the 1,8-naphthyridin-2(1H)-one skeleton which is a completely different structure from rolipram. In this report, the syntheses and structure–activity relationships of the YM-10335 derivatives were described. Some compounds showed selective inhibitory activities for PDE 4 derived from human peripheral blood cells and no effect on the other PDE types (1, 2, 3, 5). The inhibition of the tumor necrosis factor-alpha (TNF-α) release in vitro and the carrageenan-induced pleurisy in rats were also described.
为了开发新型的口服活性磷酸二酯酶(PDE)4抑制剂,我们使用化学库进行了随机筛选,发现了具有1,8-萘啶-2(1H)-酮骨架的YM-10335,该结构与罗普拉姆截然不同。在本报告中,描述了YM-10335衍生物的合成及其结构-活性关系。一些化合物对来源于人外周血细胞的PDE 4表现出选择性抑制活性,而对其他类型的PDE(1、2、3、5)没有影响。同时还描述了在体外抑制肿瘤坏死因子α(TNF-α)释放以及在大鼠中通过卡拉胶诱导的胸膜炎的研究。
