  Pyrimidine and nucleoside γ-esters of l-Glu-Sar: Synthesis, stability and interaction with hPEPT1

  摘要：

  The aim of the present study was to improve the synthetic pathway of bioreversible dipeptide derivatives as well as evaluate the potential of using L-Glu-Sar as a pro-moiety for delivering three newly synthesised nucleoside and pyrimidine L-Glu-Sar derivatives. L-Glu(trans-2-thymine-1-yl-tetrahydrofuran-3-yl ester)-Sar (I), L-Glu(thymine-1-yl-methyl ester)-Sar (II) and L-Glu(acyclothymidine)-Sar (III) were synthesised and in vitro stability was studied in various aqueous and biological media. Affinity to and translocation via hPEPT1 was investigated in mature Caco-2 cell monolayers, grown on permeable supports. Affinity was estimated in a competition assay, using [C-14] labelled Gly-Sar (glycylsarcosine). Translocation was measured as pHi-changes induced by the substrates using the fluorescent probe BCECF and an epifluorescence microscope setup. All dipeptide derivatives released the model drugs quantitatively by specific base-catalysed hydrolysis at pH > 6.0. II was labile in aqueous buffer solution, whereas 1 and III showed appropriate stability for oral administration. In 10% porcine intestinal homogenate, the half-lives of the dipeptide derivatives indicated limited enzyme catalyzed degradation. All compounds showed good affinity to hPEPT1, but the Compounds I and III showed not to be translocated by hPEPT1. The translocation of the L-Glu-Sar derivative of acyclovir, L-Glu(acyclovir)-Sar was also investigated and showed not to take place. Consequently, L-Glu-Sar seems to be a poor pro-moiety for hPEPT1-mediated transport. (c) 2005 Elsevier B.V. All rights reserved.

• N-hydroxymethyl Derivatives of Nitrogen Heterocycles as Possible Prodrugs I: N-hydroxymethylation of Uracils

  constants for formation of N-1-hydroxymethyl derivatives were approximately twice those for formation of N-3-hydroxymethyl derivatives, and they were formed more rapidly throughout the pH 3--8 range. Substituents at C-5 of uracil had little effect on the thermodynamics of N-hydroxymethylation. The potential usefulness of N-hydroxymethyl compounds as prodrugs is discussed.

  制备了1，3-二羟甲基尿嘧啶，3-羟甲基-1-甲基尿嘧啶和1-羟甲基-3-甲基尿嘧啶的固体样品，并通过光谱分析确认了它们的结构。还研究了在甲醛水溶液中形成N-羟甲基化尿嘧啶的热力学和动力学。用于形成N-1-羟甲基衍生物的平衡常数大约是用于形成N-3-羟甲基衍生物的平衡常数的两倍，并且它们在整个pH 3--8范围内的形成速度更快。尿嘧啶C-5处的取代基对N-羟甲基化的热力学影响很小。讨论了N-羟甲基化合物作为前药的潜在用途。
