1. Affinity and translocation relationships via hPEPT1 of H-X aa-Ser-OH dipeptides: evaluation of H-Phe-Ser-OH as a pro-moiety for ibuprofen and benzoic acid prodrugs
Diana Højmark Omkvist, Dennis Jespersen Trangbæk, Jemma Mildon, James S Paine, Birger Brodin, Mikael Begtrup, Carsten Uhd Nielsen Eur J Pharm Biopharm. 2011 Feb;77(2):327-31. doi: 10.1016/j.ejpb.2010.12.009. Epub 2010 Dec 13.
The intestinal di/tri-peptide transporter 1 (hPEPT1) has been suggested as a drug delivery target for peptide-based prodrugs. The aim of the study was to synthesize a series of 11 serine-containing dipeptides (H-X(aa)-Ser-OH) and to investigate the relationship between binding to and transport via hPEPT1. An additional aim was to design a dipeptide which could serve as a pro-moiety for prodrugs targeted to hPEPT1. X(aa) was chosen from the 20 proteogenic amino acids. The dipeptides were synthesized using solid phase peptide synthesis. The K(i)-values of H-X(aa)-Ser-OH dipeptides for hPEPT1 in MDCK/hPEPT1 cells ranged from 0.14 mM (logIC(50)=-0.85 ± 0.06) for H-Tyr-Ser-OH to 0.89 mM (logIC(50)=-0.09 ± 0.02) for H-Gly-Ser-OH, as measured in a competition assay with [(14)C]Gly-Sar. The dipeptides were translocated via hPEPT1 with K(m)-values in the range of 0.20 (logIC(50)=-0.69 ± 0.04) for H-Met-Ser-OH to 1.04 (logIC(50)=0.02 ± 0.04) mM for H-Gly-Ser-OH. The relationship between ligand and transportate properties indicated that the initial binding of the ligand to hPEPT1 is the major determinant for translocation of the investigated dipeptides. H-Phe-Ser-OH was selected as a pro-moiety, and two prodrugs were synthesized, i.e. H-Phe-Ser(Ibuprofyl)-OH and H-Phe-Ser(Bz)-OH. Both H-Phe-Ser(Ibuprofyl)-OH and H-Phe-Ser(Bz)-OH had high affinity for hPEPT1 with K(i)-values of 0.07 mM (logIC(50)=-0.92 ± 0.12) and 0.12 mM (logIC(50)=-1.17 ± 0.40), respectively. However, none of the prodrugs were translocated via hPEPT1. This indicated that the coupling of the drug compounds to the peptide backbone did not decrease transporter binding, but abolished translocation, and that high affinity of prodrugs does not necessarily translate into favourable permeation properties.
2. Cooperativity between the Substrate and Ligand in Palladium-Catalyzed Allylic Alkylation Using 1-Aryl-1-propynes

A monoprotected amino acid Bz-Gly-OH assists in the allylic alkylation of a variety of ketones, β-keto esters, aldehydes, etc., during enamine-palladium catalysis. Density functional theory calculations reveal that Bz-Gly-OH assists in the formation of an enamine that attacks the π-allylpalladium complex via an outer sphere mechanism. The preliminary result points to an asymmetric allylic alkylation under a new mode of bifunctional catalysis.
3. Protease-catalyzed tripeptide (RGD) synthesis
J So, J Shin, B Kim Enzyme Microb Technol. 2000 Feb 1;26(2-4):108-114. doi: 10.1016/s0141-0229(99)00132-5.
The tripeptide Bz-Arg-Gly-Asp(-OMe)-OH was synthesized by enzymatic method. Bz-Arg-Gly-OEt was synthesized by trypsin in ethanol containing 0.1 M Tris/HCl buffer (pH 8.0), and then H-Asp(-OMe)(2) was incorporated into the Bz-Arg-Gly-OEt using chymopapain in 0.25M CHES/NaOH buffer (pH = 9.0, EDTA 10 mM). The yield of Bz-Arg-Gly-OEt and Bz-Arg-Gly-Asp(-OMe)-OH were 80% and 70% using 1M Bz-Arg-OEt and 0.5M Bz-Arg-Gly-OEt, respectively. For Bz-Arg-Gly-OEt synthesis reaction at high concentrations of the substrates, the buffer content in ethanol was a key factor to determine the optimal reaction condition. In Bz-Arg-Gly-Asp(-OMe)-OH synthesis reaction, the yield was low in organic solvent due to various side products such as Bz-Arg-OH, Bz-Arg-Gly-OH, and Bz-Arg-Gly-Asp(-OMe)-Asp(-OMe)-OH, suggesting that chymopapain has a very broad substrate specificity of the S(1) site. The Bz-Arg-Gly-Asp(-OMe)-OH synthesis rate and its yield were dramatically elevated and the side reactions were reduced using only the CHES/NaOH buffer (pH = 9.0, EDTA 10 mM) as a reaction media. The final product Bz-Arg-Gly-Asp(-OMe)-OH was identified to be formed via C-terminal hydrolysis of Bz-Arg-Gly-Asp(-OMe)(2) after the nucleophile, H-Asp(-OMe)(2), was added.
