  5-取代基-2（1 H）-吡啶酮衍生物作为抗纤维化剂的合成及构效关系

  摘要：

  吡啶酮化合物（例如吡非尼酮（PFD）和氟苯尼酮（AKF-PD））是多靶点抗纤维化药物。以PFD和AKF-PD为主导化合物，合成了两种新型的（5-取代基）-2（1 H）-吡啶酮化合物，以维持多靶点性质并克服快速代谢的缺点。这些衍生物通过以AKF-PD作为阳性对照的MTT分析显示出对NIH3T3细胞的良好增殖抑制活性。化合物5b具有很高的抗纤维化作用，IC 50为0.08 mmol / L，约为AKF-PD的34倍。还讨论了吡啶酮衍生物作为抗纤维化剂的SAR。

  Two series of new pirfenidone derivatives, in which phenyl groups or benzyl groups are attached to the nitrogen atom of the pyridin-2(1H)-one moiety were synthesized and evaluated as anti-fibrosis agents. Among them, compound 5d, with a (S)-2-(dimethylamino) propanamido group in the R2 position (series 1) exhibited 10 times the anti-fibrosis activity (IC50: 0.245 mM) of pirfenidone (IC50: 2.75 mM)

  Oxidative stress, inflammation and fibrosis can cause irreversible damage on cell structure and function of kidney and are key pathological factors in Diabetic Nephropathy (DN). Therefore, multi-target agents are urgently need for the clinical treatment of DN. Using Pirfenidone as a lead compound and based on the previous research, two novel series (5-trifluoromethyl)-2(1H)-pyridone analogs were designed and synthesized. SAR of (5-trifluoromethyl)-2(1H)-pyridone derivatives containing nitrogen heterocyclic ring have been established for in vitro potency. In addition, compound 8, a novel agent that act on multiple targets of anti-DN with IC50 of 90 mu M in NIH3T3 cell lines, t(1/2) of 4.89 +/- 1.33 h in male rats and LD50 > 2000 mg/kg in mice, has been advanced to preclinical studies as an oral treatment for DN.
