  Structure and function of eritadenine and its 3-deaza analogues: Potent inhibitors of S-adenosylhomocysteine hydrolase and hypocholesterolemic agents

  摘要：

  d-Eritadenine (DEA) is a potent inhibitor of S-adenosyl-l-homocysteine hydrolase (SAHH) and has hypocholesterolemic activity. We have hypothesized that 3-deaza-DEA (C3-DEA) and its analogues retain high level of SAHH inhibitory activity and have resistance to deamination and glycosidic bond hydrolysis in vivo. Such C3-DEA analogues would have much higher hypocholesterolemic activity. C3-DEA, and its methyl ester (C3-OMeDEA) and its methyl amido (C3-NMeDEA) were synthesized to examine their SAHH inhibitory and hypocholesterolemic activities. A crystal structure of SAHH containing C3-DEA was determined and confirmed that DEA and C3-DEA bound to the same site of SAHH with the same binding mode. The SAHH inhibitory activities of C3-DEA (K(I)=1.5 microM) and C3-OMeDEA (K(I)=1.5 microM) are significantly lower than that of DEA (K(I)=30 nM), while rats fed by C3-DEA and C3-OMeDEA decrease the total plasma cholesterol and phospholipids by 36-40% and 23%, respectively, which is similar to the level of reductions (42% and 27%) by DEA. C3-NMeDEA lost most of the SAHH inhibitory activity (K(I)=30 microM) and dietary C3-NMeDEA does not decrease cholesterol and phospholipid in plasma but decreases the triacylglycerol level by 16%. DEA and C3-DEA analogues are neither substrates nor inhibitors of adenosine deaminase.

  Synthesis and Biological Effects of Acyclic Analogs of Deazapurine Nucleosides

  摘要：

  三种基本类型的S-腺苷-L-同型半胱氨酸水解酶（SAHase）抑制剂的3-脱氮类似物（S）-DHPA（I），二十二碳四烯二烯二十一烯（II）和AHPA（III）已经制备。3-脱氮腺嘌呤（V），3-脱氮嘌呤（VI），1-脱氮腺嘌呤（VII）和4-氨基-6-溴-5-氰基吡咯并[2,3-d]嘧啶（XXII）与（R）-2,2-二甲基-4-对甲苯磺酸氧甲基-1,3-二氧杂环戊烷（XIIIb）烷基化，随后经过酸水解，得到相应的（S）-2,3-二羟基丙基衍生物XVIIa-XIXa和XXV。将V和VII与2,3-O-环己基-D-赤藓糖内酯（XXIX）反应，随后在酸性介质中去除保护基，得到二十七烯和二十八烯。化合物V和VII与溴乙醛二乙醚缩醛烷基化，得到N-(2,2-二乙氧基乙基)衍生物XXXII和XXXIII，其中取代缩醛基团在原位释放，并通过氰醇反应后经酸水解转化为XXX和XXXI。烷基化在二甲基甲酰胺中用碱金属钠或铯盐进行。只有3-脱氮腺嘌呤衍生物XVIIa、二十七烯和XXX表现出酶抑制和抗病毒活性。
