(S)-9-(2,3-dihydroxy-1-propoxymethyl)guanine has potent antiherpetic activity which is superior to the corresponding racemic mixture or the (R)-enantiomer and also is much more potent than 9-(2-hydroxyethoxymethyl)guanine. Acyl derivatives (prodrugs) of the (S)-enantiomer, which are more effective than the corresponding (R)-enantiomer analogs or related racemic mixtures provide formulation advantages and even higher plasma half lives in animals or man than the (S)-isomer.
(S)-9-(2,3-二羟基-1-丙氧甲基)鸟苷具有强大的抗疱疹活性,优于相应的消旋混合物或(R)-对映体,也比9-(2-羟乙氧甲基)鸟苷更有效。 (S)-对映体的酰衍生物(前药)比相应的(R)-对映体类似物或相关的消旋混合物更有效,提供了配方优势,并且在动物或人体中的血浆半衰期比(S)-异构体更长。
