PNAS:新型糖皮质激素受体调节剂具有良好体内抗炎活性

2019-06-24 海北 MedSci原创

已有的研究显示,非甾体化合物CpdX,最初在20年前被确定为可能的孕激素,不久之后,其被作为治疗炎症性疾病的可能药物,选择性地触发NFκB/ AP1介导的糖皮质激素受体的间接反式阻断功能。因此,其可能是一个选择性糖皮质激素受体激动剂调节剂(SEGRAM)。

现在,研究人员进一步证明,给予小鼠后,CpdX及其一种氘代衍生物CpdX-D3可以像合成的糖皮质激素(例如地塞米松)一样有效地抑制诱发的皮肤特应性皮炎,诱发的牛皮癣样炎症,房子尘螨(HDM)诱发的哮喘样过敏性肺炎,胶原诱导的关节炎,诱发的溃疡性结肠炎,和卵清蛋白诱导的过敏性结膜炎。

有趣的是,在HDM诱导的哮喘样过敏性肺部炎症和胶原诱导的关节炎的情况下,CpdX抗炎活性由两种CpdX对映体之一选择性地发挥,即CpdX(eA)或CpdX-D3( EA)。
