  Dipeptidomimetic Ketomethylene Isosteres as Pro-moieties for Drug Transport via the Human Intestinal Di-/Tripeptide Transporter hPEPT1:  Design, Synthesis, Stability, and Biological Investigations

  摘要：

  Five dipeptidomimetic-based model prodrugs containing ketomethylene amide bond replacements were synthesized from readily available alpha,beta-unsaturated gamma-ketoesters. The model drug (BnOH) was attached to the C-terminus or to one of the side chain positions of the dipeptidomimetic. The stability, the affinity for the di-/tripeptide transporter hPEPT1, and the transepithelial transport properties of the model prodrugs were investigated. ValPsi[COCH2]-Asp(OBn) was the compound with highest chemical stability in buffers at pH 6.0 and 7.4, with half-lives of 190 and 43 h, respectively. All five compounds showed high affinity for hPEPT1 (K-i values < 1 mM), and PhePsi[COCH2]Asp(OBn) and ValPsi[COCH2]Asp(OBn) had the highest affinities with K-i values of 68 and 19 muM, respectively. Am hPEPT1-mediated transport component was demonstrated for the transepithelial transport of three compounds, a finding that was corroborated by hPEPT1-mediated intracellular uptake. The results indicate that the stabilized Phe-Asp and Val-Asp derivatives are promising pro-moieties in a prodrug approach targeting hPEPT1.
