The use of two derivatives of 2-methoxy-4-methylsulfinylbenzyl alcohol is demonstrated as a safety-catchprotectinggroup and linker for solid-phase peptidesynthesis. The protectinggroup and linker are stable to TFA and are readily removed under reductive acidolytic conditions.
The 2-methoxy-4-methylsulfinylbenzyl alcohol (Mmsb-OH) safety-catch linker has been described as a useful tool to overcome two obstacles in peptidesynthesis: the solubility and fragment condensation of peptides. The incorporation of the linker into an insoluble peptide target, thereby allowing the conjugation of a poly-Lys as a “solubilizing tag”, notably enhanced the solubility of the peptide. The
