A general solid phase method for the synthesis of sequence independent peptidyl-fluoromethyl ketones

Abstract

We present here a new, general, solid phase strategy for the synthesis of sequence independent peptidyl-fluoromethyl ketones using standard Fmoc peptide chemistry. Our method is based on the synthesis of bifunctional linkers which allows the incorporation of amino acid fluoromethyl ketone unit at the C-terminal end of peptide sequences. Application of this approach for the synthesis of activity based probes for SENPs is also described.
