Abstract A number of new 5,6-disubstituted benzimidazoles have been prepared and their substrate properties for recombinant E. coli purine nucleoside phosphorylase (PNP; the product of the deoD gene) in the transglycosylation reaction were investigated. The heterocyclic bases showed good substrate activity for PNP and the ribo- and 2′-deoxyribonucleosides were synthesized. The predominant (OMe and
摘要 已经制备了许多新的5,6-二取代的苯并咪唑,并研究了它们在转糖基化反应中对重组大肠杆菌嘌呤核苷磷酸化酶(PNP;deoD基因的产物)的底物性质。杂环碱基对PNP具有良好的底物活性,并合成了核糖和2'-脱氧核糖核苷。观察到5-取代的6-氟-1-(-1- d-核呋喃呋喃糖基)苯并咪唑的主要(OMe和OEt)或排他的(O i -Pr,吗啉代和N-甲基哌嗪子)形成。区域异构体6-甲氧基,6-乙氧基或6-异丙氧基取代的1-(2-脱氧-β- d的形成在相应碱基的反式-2-脱氧核糖基化反应中观察到-(呋喃核糖基)-5-氟苯并咪唑。具有6-氟苯并咪唑的大体积5-取代基的区域异构N 1-核苷的主要或排他性指向可容纳这些基团的大肠杆菌PNP活性位点中的大疏水口袋。对合成核苷的生物学活性进行了研究,发现对多种DNA和RNA病毒没有抑制活性。该化合物也缺乏明显的细胞毒性。 已经制备了许多新的5,6-二取代的
