The 3-nitro-2-pyridinesulfenyl (Npys) derivative of cysteine was prepared and used to facilitate the formation of an unsymmetrical disulfide bond. Since this derivative is stable in trifluoroacetic acid:CH2 Cl2 (1:1) and anhydrous hydrogen fluoride, Boc-Cys(Npys) could be used directly in solid
Controlled peptide-protein conjugation by means of 3-nitro-2-pyridinesulfenyl protection-activation.

The disulfide bond in S-3-nitro-2-pyridinesulfenyl (S-Npys) compounds is stable towards the acid treatment used in solid-phase peptide synthesis, yet the liability of S-Npys-peptides towards nucleophiles enables the conjugation to proteins to proceed under mild conditions. Thus Boc-Cys(Npys)-OH was coupled as

Some T cell epitopes become inactive when their thiols are blocked with various irreversible reagents (Régnier-Vigouroux, 1988; Maillère, 1992; Maillère et al., 1993). Blocking protein and peptide thiols with BCNP (Boc-Cys(Npys)-OH) constitutes a most appropriate strategy when searching for thiol-containing
