5-Aryl-2,2-dialkyl-4-phenyl-3(2H)furanone derivatives were studied as a novel class of selective cyclooxygenase-2 inhibitors with regard to synthesis, in vitro SAR, antiinflammatory activities, pharmacokinetic considerations, and gastric safety. 1f, a representative compound for methyl sulfone derivatives, showed a COX-2 IC(50) comparable to that of rofecoxib. In case of 20b, a representative compound
研究了5-芳基-2,2-二烷基-4-苯基-3(2H)呋喃酮衍生物作为一类新型的选择性环加氧酶-2抑制剂的合成,体外SAR,抗炎活性,药代动力学和胃安全性。图1f是甲基砜衍生物的代表性化合物,其COX-2 IC(50)与罗非考昔相当。在20b(磺胺衍生物的代表性化合物)的情况下,通过预防模型观察到针对佐剂诱发的关节炎的有效抗炎ED(50)为0.1 mg kg(-1)day(-1),将20b定位为其中之一报道过的大多数有效的COX-2抑制剂。此外,20b表现出很强的镇痛活性,如它对Sprague-Dawley大鼠的角叉菜胶诱导的热痛觉过敏的ED(50)值为0.25 mg / kg所表明的。3(2H)呋喃酮衍生物在7天重复给药后显示出作为选择性COX-2抑制剂的适当胃部安全性。3(2H)呋喃酮支架的高效COX-2抑制剂可被认为适用于安全性得到改善的下一代COX-2选择性关节炎药物。
