  描述：

  bis(pivaloyloxymethyl) α-methyleneglutarate 在 palladium on activated charcoal 苯磺酰胺 、 氢气 、 triphenylphosphine dibromide 1:1 addition complex 作用下， 以 四氢呋喃 、 乙醚 、 二氯甲烷 、 N,N-二甲基乙酰胺 、 乙酸乙酯 为溶剂， 反应 67.0h， 生成 [(3S)-3-[[4-[(2,4-diaminopteridin-6-yl)methyl-methylamino]benzoyl]amino]-4-(2,2-dimethylpropanoyloxymethoxy)-4-oxobutyl]-[5-(2,2-dimethylpropanoyloxymethoxy)-2-(2,2-dimethylpropanoyloxymethoxycarbonyl)-5-oxopentyl]phosphinic acid

  摘要：

  Ester prodrugs of the phosphinate pseudopeptide N-[(4-deoxy-4-amino-10-methyl)pteroyl]glutamate-gamma-[psi P(0)(OH)]-glutarate (1a) were synthesized. H-phosphinic acids derived from N-Cbz vinyl glycine esters were converted to the desired pseudopeptides by Michael addition to alpha-methyleneglutarate esters. Pivaloyloxymethyl (POM) ester moieties were incorporated in both the N-terminal and C-terminal fragments prior to formation of either C-P bond. N-Alkylation of the corresponding amides derived from p-(N-methyl)aminobenzoic acid with 2,4-diamino-6-(bromomethyl)pteridine gave the target compounds. POM esters of methotrexate and the corresponding gamma-glutamyl conjugate were also synthesized using the same strategy. All prodrugs were evaluated in Chinese hamster ovary cells. Although the pseudopeptide prodrugs were ineffective, prodrugs of methotrexate and the corresponding gamma-glutamyl conjugate were equipotent with the parent compounds. Stability of the prodrugs was investigated in both phosphate buffer and cell line medium to provide a rationale for the observed biological data.
