SULFOXONIUM YLIDE DERIVATIVES AS PROBES FOR CYSTEINE PROTEASE
-
Paragraph 0371-0373, (2020/07/14)
The present invention relates to compounds of formula I bearing a sulfoxonium ylide moiety as warhead, or salts thereof. Such compounds can be used as activity-based probes for cysteine proteases such as cathepsin X, in methods of detecting cysteine protease activity and in related diagnostic or therapeutic methods.

A direct oxo-ester peptide ligation method has been developed. Through the use of an activated C-terminal para nitrophenyl ester (1), it is possible to achieve direct cysteine ligations (1 + 2 → 4). Peptide substrates incorporating bulky C-terminal amino acids (1) can be accommodated with high reaction efficiency. Copyright
