A new class of tumor necrosis factor alpha (TNF-alpha) synthesis inhibitors based on a N-2,4-pyrimidine-N-phenyl-N'-alkyl urea scaffold is described. Many of these compounds showed low-nanomolar activity against lipopolysaccharide stimulated TNF-alpha production. Two analogs were tested in an in vivo rat iodoacetate model of osteoarthritis and shown to be orally efficacious. X-ray co-crystallization
描述了一种基于N-2,4-嘧啶-N-苯基-N'-烷基脲支架的新型肿瘤坏死因子α(TNF-α)合成抑制剂。这些化合物中有许多对脂多糖刺激的TNF-α产生低纳摩尔活性。在骨关节炎的体内大鼠碘乙酸盐模型中测试了两个类似物,并且显示出口服有效。用突变的p38α进行的X射线共结晶研究表明,这些三取代的尿素与假单双环构象的ATP结合口袋相互作用,这是由于分子内氢键相互作用的存在所致。
