The majority of potential antiviral agents which are currently undergoing clinical trials are inhibitors of the replication of nucleic acids. The most common class of these inhibitors are nucleoside analogues and the elucidation of synthetic routes to these compounds has been of interest for many years as many are anticancer agents. One synthetic development has been the application of bio-transformations to nucleoside syntheses. This topic has been reviewed recently (Shirae et al., 1991) but this review is not widely available. In the present review, the application of biotechnology to the synthesis of antiviral agents including those which are not nucleoside analogues will be discussed. Enzymatic syntheses of nucleosides can be simpler and quicker than syntheses carried out by chemical methods. The most useful enzymes are those found in catabolic pathways. Nucleoside phosphorylases and N-deoxyribosyltransferases have both been widely used for nucleoside synthesis catalysing the transfer of sugar residues from a donor nucleoside to a heterocyclic base. Enzymatic methods have also been applied to the resolution of racemic mixtures and adensoine deaminase is a convenient catalyst for the hydrolysis of amino groups on purines and purine analogues. Regioselective deprotection of nucleoside esters has been achieved with lipases and these enzymes have also been applied to the synthesis of esters of sugar-like alkaloids. The latter have potential as inhibitors of the replication of HIV. Esterases have also been used in combined chemical and enzymatic syntheses of organophosphorus antiviral agents.
