Title

NOVEL AND EFFICIENT METHOD FOR SOLID PHASE SYNTHESIS OF UREA-CONTAINING PEPTIDES TARGETING PROSTATE SPECIFIC MEMBRANE ANTIGEN (PSMA) IN COMPARISON WITH CURRENT METHODS

Pages

  917-926

Abstract

 The basic chemical structure of most prostate specific membrane antigen (PSMA) inhibitorswhich are now in pre-clinical and clinical studies is Glu-Ureido-based peptides. Synthesis of urea-based PSMA inhibitors includes two steps: 1- ISOCYANATE intermediate formation and 2- UREA BOND formation. In current methods, ISOCYANATE is formed in liquid phase and then reacts with amine existing in liquid phase or bound to SOLID PHASE for UREA BOND formation. In this study, we developed a new facile method for formation of both ISOCYANATE and urea on SOLID PHASE under standard peptide coupling conditions. The SOLID PHASE-bound ISOCYANATE served as intermediate to form UREA BOND. To monitor reaction progress qualitative test (Kaiser Test) and On-Bead FT-IR spectroscopy were used. The structure of GLUTAMATE-UREA-LYSINE (EUK) was confirmed using LC-Mass and 1H-NMR. This novel method successfully was applied to synthesize of another urea-based peptide containing a sequence of Glu-Urea-Lys (OMe) - GABA-Tyr-Tyr-GABA and the bifunctional linker hydrazinonicotinamide (HYNIC) as well.
