  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。

  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.
