A new class of tumor necrosis factor alpha (TNF-alpha) synthesis inhibitors based on an N-2,4-pyrimidine-N-phenyl-N'-phenyl urea scaffold is described. Many of these compounds showed low-nanomolar activity against lipopolysaccharide stimulated TNF-alpha production. X-ray co-crystallization studies with mutated p38alpha showed that these trisubstituted ureas interact with the ATP-binding pocket in a pseudo-bicyclic conformation brought about by the presence of an intramolecular hydrogen bonding interaction.
描述了一类基于N-2,4-嘧啶-N-苯基-N'-苯基脲支架的新型肿瘤坏死因子α(TNF-α)合成抑制剂。这些化合物中的许多对脂多糖刺激的TNF-α产生表现出低纳摩尔活性。对突变型p38α进行的X射线共结晶研究表明,这些三取代脲以由分子内氢键相互作用导致的假双环构象与ATP结合口袋相互作用。
