  摘要：

  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。

  Eight novel single amino acid (6-11) and dipeptide (12, 13) tyrosine P-O esters of cyclic cidofovir ((S)-cHPMPC, 4) and its cyclic adenine analogue ((S)-cHPMPA, 3) were synthesized and evaluated as prodrugs. In vitro IC50 values for the prodrugs (<0.1-50 mu M) vs vaccinia, cowpox, human cytomegalovirus, and herpes simplex type 1 virus were compared to those for the parent drugs ((S)-HPMPC, 2; (S)HPMPA, 1; IC50 0.3-35 mu M); there was no cytoxicity with KB or HFF cells at <= 100 mu M. The prodrugs exhibited a wide range of half-lives in rat intestinal homogenate at pH 6.5 (<30-1732 min) with differences of 3-10x between phostonate diastereomers. The tyrosine allcylamide derivatives of 3 and 4 were the most stable. (L)-Tyr-NH-i-Bu cHPMPA (11) was converted in rat or mouse plasma solely to two active metabolites and had significantly enhanced oral bioavailability vs parent drug 1 in a mouse model (39% vs <5%).
