A tyrosine-based (phosphonylmethoxyalkyl)purine or -pyrimidine conjugate is provided. In some embodiments, the conjugate includes tyrosine based amino acid or dipeptide moieties of (S)-9-(3-hydroxy-2-phosphonyl-methoxypropyl)adenine or its cytosine analogue. A method of synthesizing such conjugates based on Boc-protected amino acid or dipeptides is also provided. In addition, a method of isomerizing an (S,S)-diastereoisomer to an (S,R)-diastereoisomer of an amino acid-based or dipeptide-based conjugate by a process including transesterification is provided. A method of inhibiting viral infection and a method of treating viral infection based on (phosphonylmethoxyalkyl)purine or -pyrimidine conjugates is also provided.
提供了一种基于酪氨酸的(磷酰甲氧基烷基)嘌呤或嘧啶共轭物。在某些实施例中,该共轭物包括(S)-9-(3-羟基-2-磷酰甲氧基丙基)腺嘌呤或其胞嘧啶类似物的酪氨酸基氨基酸或二肽基团。还提供了一种基于Boc保护氨基酸或二肽合成这种共轭物的方法。此外,提供了一种通过包括酯交换的过程将(S,S)-对映异构体异构化为氨基酸或二肽基共轭物的(S,R)-对映异构体的方法。还提供了一种基于(磷酰甲氧基烷基)嘌呤或嘧啶共轭物来抑制病毒感染和治疗病毒感染的方法。
