This communication describes the synthesis and in vitro and in vivo evaluation of a novel potent series of phosphodiesterase type (IV) (PDE4) inhibitors. Several of the compounds presented possess low nanomolar IC50's for PDE4 inhibition and excellent in vivo activity for inhibition of TNF-alpha levels in LPS challenged mice (mouse endotoxemia model). Emesis studies (dog) and efficacy in a SCW arthritis model for the most potent PDE4 inhibitors are presented.
本通讯描述了一系列新型强效磷酸二酯酶IV型(PDE4)抑制剂的合成及其体外和体内评价。所展示的几种化合物对PDE4抑制具有低纳摩尔IC50值,并且在抑制脂多糖攻击的小鼠(小鼠内毒素血症模型)中TNF-α水平方面具有优异的体内活性。展示了最有效的PDE4抑制剂在催吐研究(犬)和链球菌细胞壁(SCW)关节炎模型中的疗效。
