  6-氨基-2,4,5-三甲基吡啶-3-醇：一种新的通用合成途径和抗血管生成活性

  摘要：

  已开发出一种新的合成策略，该方法可通过六步法从吡ido醇·HCl制备多种6-氨基-2,4,5-三甲基吡啶-3-醇。这种方法的特点是，通过使用钯（Buchwald-Hartwig胺化反应），将重要的氨基引入到3-苄氧基-6-溴-2,4,5-三甲基吡啶（13）的C（6）位置，该中间体是关键中间体。 0）过渡金属，它肯定会扩大氨基取代基的范围。使用本文所述方法制备的某些类似物在鸡绒膜尿囊膜（CAM）分析中显示出高水平的抗血管生成和抗肿瘤活性，证明了这些新的氨基吡啶并作为抗血管生成剂的潜力。

  The present invention relates to an amidopyridinol derivative or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition including an amidopyridinol derivative or a pharmaceutically acceptable salt thereof as an active component. An amidopyridinol derivative represented by Chemical Formula 1 or a pharmaceutically acceptable salt thereof has an excellent antiangiogenic effect in a chorioallantoic membrane model, and thus is useful as an agent for preventing or treating diseases associated with angiogenesis, such as macular degeneration or arthritis, and also has an excellent colitis-inhibitory effect in a model of inflammatory bowel diseases, and thus is useful as an agent for preventing or treating inflammatory bowel diseases. Upon inoculation of lung cancer cells in a chorioallantoic membrane model, the amidopyridinol derivative of Chemical Formula 1 or the pharmaceutically acceptable salt thereof inhibits angiogenesis and tumor growth that are caused by tumorigenesis, and also inhibits the activity of cathepsin S that plays an important role in metastasis and invasion of cancer, and thus is useful as an inhibitor of cancer growth and metastasis.

  本发明涉及一种酰胺吡啶醇衍生物或其药学上可接受的盐，以及包括酰胺吡啶醇衍生物或其药学上可接受的盐作为活性成分的药物组合物。由化学式1表示的酰胺吡啶醇衍生物或其药学上可接受的盐在绒毛膜模型中具有出色的抗血管生成作用，因此可用作预防或治疗与血管生成相关的疾病，如黄斑变性或关节炎的药物，并且在炎性肠道疾病模型中具有出色的结肠炎抑制作用，因此可用作预防或治疗炎性肠道疾病的药物。在绒毛膜模型中接种肺癌细胞时，化学式1的酰胺吡啶醇衍生物或其药学上可接受的盐抑制了由肿瘤发生引起的血管生成和肿瘤生长，并且还抑制了在癌症转移和侵袭中发挥重要作用的半胱氨酸蛋白酶S的活性，因此可用作抑制癌症生长和转移的药物。

  Although the pathogenesis of inflammatory bowel disease (IBD) is complex, attachment and infiltration of leukocytes to gut epithelium induced by pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) represents the initial step of inflammation in IBD. Previously, we have reported that some 6-amino-2,4,5-trimethylpyridin-3-ols have significant levels of antiangiogenic activity via PI3K inhibition. Based on the reports that angiogenesis is involved in the aggravation of IBD and that PI3K is a potential target for IBD therapy, we investigated whether the scaffold has inhibitory activity against in vitro and in vivo models of colitis. Many analogues showed >80% inhibition against TNF-alpha-induced monocyte adhesion to colon epithelial cells at 1 mu M. Compound 8m showed IC50 = 0.19 mu M, which is about five orders of magnitude better than that of 5-aminosalicylic acid (5-ASA, IC50 = 18.1 mM), a positive control. In a rat model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis, orally administered 8m dramatically ameliorated TNBS-induced colon inflammation. It was demonstrated by a high level of suppression in myeloperoxidase (MPO), a surrogate marker of colitis, as well as almost perfect recovery of colon and body weights in a dose-dependent manner. Compared to sulfasalazine, a prodrug of 5-ASA, compound 8m showed >300-fold better efficacy in those parameters. Taken together, 6-amino-2,4,5-trimethylpyridin-3-ols can provide a novel platform for anti-IBD drug discovery. (C) 2016 Elsevier Ltd. All rights reserved.
