title: Large-scale production of peptides using the solid-phase continuous flow method. Preparative synthesis of the novel tachykinin antagonist MEN 10627.
abstract: The large-scale solid-phase continuous flow synthesis of the bicyclic peptide MEN 10627, a new potent Neurokinin A receptor antagonist, is described using the Fmoc-polyamide method on both macrosorb 125 and Macrosorb 250 resin. A new synthesizer designed in-house was realized by assembling Whitey valves and Waters pump in order to allow small-scale (0.0001 mol; 1 x 10 cm Omnifit columns) synthetic studies which were strongly predictive of the conditions required for large-scale (0.01-0.10 mol; 3.6 or 5.9 x 46 cm Büchi columns) production, performed on the same apparatus.
