An efficient synthesis of tetrazole analogues of aminoacids starting from Nα-Fmoc aminoacid in a three-step protocol is reported. The free amino tetrazoles were obtained in good yields and with excellent purity after removal of the Fmoc group. The synthesis of analogues of aspartic and glutamic acids in which the 5-tetrazolyl moiety is inserted at the β/γ carboxyl group starting from Fmoc-Asn and

Increasing the activity: Peptideinhibitors of the Keap1–Nrf2 protein–proteininteraction in which unnatural amino acids are incorporated in heptamer sequences have been developed. The starting sequence has been co‐crystallised with the Keap1 Kelch domain, and the best peptides have Keap1 affinities in the nanomolar range in fluorescence polarisation (FP) and isothermal titration calorimetry (ITC)

Leu-enkephalin and d-Ala2-Leu-enkephalin were modified at their N- and C-termini with guanidyl and tetrazole groups. The resulting molecules were prepared in solution or by solid phase peptidesynthesis. The affinity of the different analogues at mu (MOP) and delta opioid receptors (DOP) was then assessed by competitive binding in stably transfected DOP and MOP HEK293 cells.
