Metalloporphyrin receptors for histidine-containing peptides

Two new ditopic metalloporphyrin receptors constructed by combining metalloporphyrin with crown ethers have been prepared and characterized. 1H NMR and MS spectra confirmed the complexation of receptor with peptide driven by coordination interaction and hydrogen bonding. UV/vis experiments revealed that the receptors exhibited high binding affinity to histidine-containing peptides. These receptors could differentiate short peptides of C-terminal histidine and N-terminal histidine and formed the most stable complexes with tripeptide.
Bromelain catalyzed synthesis of peptides in organic solvent

For the first time, immobilized bromelain was shown to maintain high catalytic activity in organic solvent and to form peptide bonds. It requires only 7 hours to obtain Cbz-Gly-L-Leu-OMe in 85% yield. The precursor of aspartame (Cbz-L-Asp-L-Phe-OMe) and other dipeptides were also synthesized by this method.
