in a short synthesis of nucleoside analogues with pyrimidine and purine heterobases. The protocol is based on a typical nucleophilic substitution process. Uracil, thymine, 6-chloropurine, and some adenines gave the expected 4-heterosubstituted products along with the isomeric 2-heterosubstituted compounds as minor components. Samples of selected products were evaluated for their antiviral activity in

Flow-Synthesis of Nucleosides Catalyzed by an Immobilized Purine Nucleoside Phosphorylase from<i>Aeromonas hydrophila</i>: Integrated Systems of Reaction Control and Product Purification
A purinenucleosidephosphorylase from Aeromonas hydrophyla (AhPNP) was covalently immobilized in a pre‐packed stainless steel column containing aminopropylsilica particles via Schiff base chemistry upon glutaraldehyde activation. The resulting AhPNP‐IMER (Immobilized Enzyme Reactor, immobilization yield ≈50%) was coupled on‐line through a 6‐way switching valve to an HPLC apparatus containing an analytical
戊二醛活化后,通过席夫碱化学将水合气单胞菌(Ah PNP)的嘌呤核苷磷酸化酶共价固定在预先包装的含有氨基丙基二氧化硅颗粒的不锈钢柱中。所得的Ah PNP-IMER(固定化酶反应器,固定化率≈50%)通过六通切换阀在线连接至包含分析或半制备色谱柱的HPLC设备。通过将反应混合物连续泵送通过Ah进行5种6-修饰的嘌呤核糖核苷的合成PNP-IMER,直到达到最高转化率,然后将反应混合物进行色谱分离。通过分数阶乘实验设计优化了Ah PNP催化转糖基化的条件(糖供体:碱基受体的比例为2:1 ; 10 mM磷酸盐缓冲液; pH 7.5;温度37°C,流速0.5 mL min -1)。在这种集成平台上将生物转化步骤与产品纯化相结合,可实现快速有效的合成过程(收率= 52–89%; <10 mg),从而最大限度地减少了样品处理。迄今为止,Ah PNP-IMER在10个月内进行了50次反应后完全保留了其活性。
