    摘要:
    1-[(S)-3-羟基-2-(磷酸甲氧基)丙基]胞苷(HPMPC,西多福韦)在C-5和N4位置上对碱基部分进行了取代修饰。这些合成的关键中间体,即()-1-[2-(磷酸甲氧基)-3-(三苯甲氧基)丙基]-5-烷基胞嘧啶(6和7)的二异丙酯,是由5-烷基-4-甲氧基嘧啶-2(1H)-酮制备而成,通过氨或一级胺的作用分别转化为相应的5-取代胞嘧啶或N4-烷基胞嘧啶衍生物。这些完全保护的磷酸酯经溴三甲基硅烷处理后,随后经水解得到自由磷酸:1-[(S)-3-羟基-2-(磷酸甲氧基)丙基]-5-甲基胞嘧啶(5-甲基-HPMPC,10),5-乙基-1-[(S)-3-羟基-2-(磷酸甲氧基)丙基]胞嘧啶(5-乙基-HPMPC,11)和一系列带有各种N4位置取代基(环丙基,环戊基,2-羟乙基,烯丙基,2-(二甲基氨基)乙基)的5-乙基-HPMPC类似物17-21。5-乙炔基-1-[(S)-3-羟基-2-(磷酸甲氧基)丙基]胞嘧啶(5-乙炔基-HPMPC,26)是由5-碘胞嘧啶衍生物23通过Sonogashira偶联与(三甲基硅基)乙炔,CuI和[PdCl2(Ph3P)2]制备的。所有制备的化合物均未在体外显示抗病毒活性。

  • Synthetic nucleosides and nucleotides. XXVIII. Synthesis of 5-alkylcytidines from 5-alkylbarbituric acids.
    作者:MINEO SANEYOSHI、SHIN'ICHI WATANABE
    DOI:10.1248/cpb.36.2673
    日期:——
    5-Alkylbarbituric acids (1b-f) were converted to 5-alkyl-2, 4, 6-trichloropyrimidines (2b-f) by using phosphoryl chloride in refluxing n-butyl acetate in the presence of N, N-diethylaniline hydrochloride. Treatment of 2 with sodium methoxide in dry acetonitrile followed by reaction with potassium ethyl mercaptide and desulfurization with Raney Ni afforded 5-alkyl-2, 4-dimethoxypyrimidines (5b-f), as key intermediates in the present study. Coupling of 5 with 1-O-acetyl-2, 3, 5-tri-O-benzoyl-β-D-ribofuranose in the presence of stannic chloride in acetonitrile afforded 5-alkyl-1-(2, 3, 5-tri-O-benzoyl)-β-D-ribofuranosyl-1, 2-dihydro-4-methoxypyrimidin-2-ones (6a-f) in quantitative yields. Ammonolysis of 6 with methanolic ammonia afforded the title 5-alkylcytidines (7a-f). Compounds 6 were also easily converted to their uridine counterparts by treatment with hydrochloric acid. Growth-inhibitory effects of 7 on cultured mouse leukemia L5178Y cells, antiviral activity against a rhabdovirus, infectious hematopoietic necrosis virus (IHNV), in cultured CHSE-214 cells and properties as a substrate of human cytidine deaminase were also examined.
    5-烷基巴比妥酸(1b-f)在N,N-二乙基苯胺盐酸盐存在下,使用磷酰氯在回流的正丁基乙酸酯中转化为5-烷基-2,4,6-三氯嘧啶(2b-f)。将2与甲氧基钠在干燥乙腈中处理,随后与乙基硫醇钾反应并在Raney Ni存在下脱硫,得到本研究的关键中间体5-烷基-2,4-二甲氧基嘧啶(5b-f)。在乙腈中锡氯存在下,将5与1-O-乙酰基-2,3,5-三-O-苯甲酰基-β-D-呋喃核糖反应,定量得到5-烷基-1-(2,3,5-三-O-苯甲酰基)-β-D-呋喃核糖基-1,2-二氢-4-甲氧基嘧啶-2-酮(6a-f)。用甲醇氨处理6得到标题5-烷基胞嘧啶核苷(7a-f)。化合物6也很容易通过与盐酸处理转化为相应的尿嘧啶核苷。还研究了7对培养的小鼠白血病L5178Y细胞的生长抑制作用、对培养的CHSE-214细胞中的传染性造血坏死病毒(IHNV)的抗病毒活性以及作为人胞嘧啶脱氨酶底物的性质。
