We report a series of novel O-(substituted benzyl) phosphoramidate prodrugs of 5-fluoro-2′-deoxyuridine for the treatment of hepatocellular carcinoma. Through structure optimization, the o-methylbenzyl analog (1t) was identified as an orally bioavailable and liver-targeted lead compound. This lead prodrug is well-tolerated at a dose up to 3 g/kg in Kuming mice via oral administration. An efficacy study
我们报告了一系列5-氟-2'-脱氧尿苷的新型O-(取代的苄基)氨基磷酸酯前药,用于治疗肝细胞癌。通过结构优化,将邻甲基苄基类似物(1t)鉴定为口服可生物利用的且靶向肝的铅化合物。通过口服给药,该铅前药在Kuming小鼠中的耐受性高达3 g / kg。一项功效研究表明,它在小鼠异种移植模型中具有良好的抑制作用(分别为61.67%和72.50%)。在Sprague–Dawley大鼠中进行的一项代谢研究表明,1t可以在肝脏中以较高的肝靶向指数释放所需的5'-单磷酸酯。
