  含金刚烷基核苷类似物的合成及抗疱疹活性

  摘要：

  研究人员对合成核苷化合物的兴趣在很大程度上可以通过这些制剂成功用于治疗病毒和肿瘤疾病来解释。尤其是3'-azido-2',3'dideoxythymidine（叠氮胸苷）能够强烈抑制HIV-1感染，在临床条件下被广泛用于治疗艾滋病患者。2-氨基-9-[(2羟基乙氧基)甲基]-6,9-二氢-1H-嘌呤（阿昔洛韦或阿昔洛韦）已被证明是对抗HSV感染的有效药物[1 -3 ]。还合成和测试了许多在核酸残基和糖片段方面都经过修饰的嘧啶衍生物（特别是 2'-脱氧尿苷类似物）[4-8]。acyctovir 的合成刺激了在无环乌定类似物系列中寻找新的抗病毒药物 [9]。然而，我们未能找到有关在核碱基中具有框架取代基的核苷类似物的合成和生物学特性的任何已发表数据。同时，人们可以预期，金刚烷片段会显着改变这些化合物的构象和理化性质，从而影响它们与细胞膜的相互作用，从而显着改变初始物质的底物性质 [10, 11]

  The Synthesis of Some 5-Substituted and 5,6-Disubstituted 2′-Deoxyuridines

  摘要：

  5-Alkyl(cycloalkyl)-2'-deoxyuridines VIa-VIf were synthesised in high yields by condensation of the corresponding silylated bases with 2-deoxy-3,5-di-O-p-toluoyl-D-erythro-pentosyl chloride in chloroform and subsequent deblocking with sodium methoxide in methanol. The beta-configuration, anti-glycosidic conformation and C2'-endo (S) sugar pucker of all of these compounds has been established from their H-1 NMR, C-13 NMR, UV and mass spectra. Under the same conditions, the condensation of silylated 5,6-trimethyleneuracil, resulted in 1:2/alpha:beta anomeric mixture (overall yield 71%) and syn-conformation of the 5,6-trimethylene-2'-deoxyuridine [Xg]. The results of the condensation of the silylated 5,6-dimethyluracil are discussed as well. No significant antiviral activity has been found in testing the synthesised compounds against a range of herpes, influenza and HIV-1 viruses.

  The silylated pyrimidine bases IIa-d were condensed with the benzyl 3,5-di-O-benzyl-2-deoxy-1,4-ditkio-D-erythro-pentofuranoside III in acetonitrile under activation by N-iodosuccinimide, giving ca 1.5 : 1/alpha: beta anomeric mixtures of the blocked nucleosides IVa-d and Va-d. in yields of 55-88%. After the separation on a silica column the pure anomers were deprotected by BCl3 or TiCl4, providing the free nucleosides VIa-d and VIIa,c,d in moderate to good overall yields. The beta- or alpha-anomeric configuration, anti-glycosidic conformation and prevailing C2'-endo(S) thiosugar pucker in the synthesized compounds were established by the combined use of the H-1, C-13 NMR and X-ray crystallography.
