In this report, we disclose the design and synthesis of a series of pentafluorosulfanyl (SF5) benzopyran derivatives as novel COX-2 inhibitors with improved pharmacokinetic and pharmacodynamic properties. The pentafluorosulfanyl compounds showed both potency and selectivity for COX-2 and demonstrated efficacy in several murine models of inflammation and pain. More interestingly, one of the compounds
在此报告中,我们公开了设计和合成一系列五氟硫烷基(SF 5)苯并吡喃衍生物作为具有改善的药代动力学和药效特性的新型COX-2抑制剂。五氟硫烷基化合物对COX-2既有效价又有选择性,并且在几种小鼠炎症和疼痛模型中均显示出功效。更有趣的是,化合物R,S - 3a在佐剂诱导的关节炎(AIA)模型中显示出卓越的功效,ED 50高达0.094 mg / kg。此外,化合物R,S - 3a的药代动力学大鼠的半衰期超过12小时,血浆药物浓度远高于其IC 90长达40小时。在AIA模型中,每周仅两次给R,S - 3a给药时,疗效仍然得以维持。总体而言,药物R,S - 3a和其他类似物是合适的候选药物,值得进一步研究以治疗炎症和疼痛以及COX-2和PGE 2在其病因中起作用的其他疾病。
