Aqueous microwave-assisted solid-phase peptide synthesis using Fmoc strategy: in-water synthesis of "difficult sequences".

A microwave assisted peptide synthesis in water using nanosized Fmoc-amino acids was developed. 5, 7, and 10 mer peptides (Leu-enkephalinamide, dermorphinamide, and a typical difficult sequence, ACP (65-74) peptide) were successfully synthesized in water according to Fmoc chemistry using water-dispersible nanoparticles with microwave irradiation.
