摘要:
2-氯-N6-(3-碘苄基)腺苷-5’-N-甲基尿嘧啶(氯-IB-MECA)是由Can-Fite公司开发的具有选择性的A3腺苷受体激动剂,可同时治疗非酒精性脂肪性肝病、非酒精性脂肪性肝炎和肝细胞癌,具有广阔的市场前景。根据起始原料的不同对氯-IB-MECA合成方法进行了系统讨论。方法1以1-O-甲基-β-D-呋喃核糖苷为起始原料,经选择性羟基保护、氧化反应、酯化反应、酰胺化、酸化及脱保护得到氯-IB-MECA。方法2以2-乙酰氧基-5-((苯甲酰氧基)甲基)四氢呋喃-3,4-二基二苯甲酸酯为原料,经Vorbruggen糖苷化反应、亲核取代反应、保护基交换、氧化反应、羧酸酰胺化得到氯-IB-MECA。方法3以四乙酰核糖为原料,经亲核取代反应、脱乙酰基、邻二羟基保护、伯醇氧化、羧酸酰胺化和水解反应得到氯-IB-MECA。方法4以β-D-呋喃呋喃糖醛酸甲酯三乙酸酯为原料,经亲核取代、酯基酰胺化和脱乙酰基后得到氯-IB-MECA。经过比较认为, 方法4原料易得,合成步骤少,反应和分离条件温和,收率高,更适合氯-IB-MECA的工业化生产。
Abstract:
2-Chloro-N6-(3-iodobenzyl) adenosine-5’-N-methyluracil (2-Cl-IB-MECA) is a selective A3 adenosine receptor agonist developed by Can-Fite company, which can simultaneously treat non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, and hepatocellular carcinoma, and has broad market prospects. The synthesis methods of 2-Cl-IB-MECA are systematically discussed based on different starting materials. Method 1 uses methyl β-D-ribofuranoside as a starting material to obtain 2-Cl-IB-MECA by selective hydroxyl protection, oxidation, esterification, amidation, acidification, nucleophilic substitution and deprotection. Method 2 uses 2-acetoxy-5-((benzoyloxy) methyl) tetrahydrofuran-3, 4-diyldibenzoate as a starting material to form 2-Cl-IB-MECA through Vorbruggen glycosylation reaction, nucleophilic substitution, protective group exchange, oxidation reaction, and amidation of carboxylic acid. Method 3 employs tetraacetylribose as a starting material, through nucleophilic substitution, deacetylation, 1, 2-dihydroxy protection, oxidation of primary alcohol, amidation of carboxylic acid, and hydrolysis to produce 2-Cl-IB-MECA. Method 4 employs β-D-ribofuranuronic acid methyl ester triacetate as a starting material, through nucleophilic substitution, amidation of ester, and deacetylation to generate 2-Cl-IB-MECA. After comparison, method 4 is considered to be more suitable for industrial production of 2-Cl-IB-MECA due to the easy availability of starting materials, fewer synthetic steps, mild reaction and separation conditions and high yield.
