Controlled peptide-protein conjugation by means of 3-nitro-2-pyridinesulfenyl protection-activation.

Int. J. Pept. Protein Res. 32(3) , 161-6, (1988)

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 mi...

Preparation of Boc-[S-(3-nitro-2-pyridinesulfenyl)]-cysteine and its use for unsymmetrical disulfide bond formation.

Int. J. Pept. Protein Res. 28(2) , 107-12, (1986)

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(N...

Effects of sulfhydryl-modifying reagents, 3-nitro-2-pyridinesulfenyl compounds, on the coupling between inhibitory receptors and GTP-binding proteins Gi/Go in rat brain membranes.

Mol. Pharmacol. 38(2) , 184-91, (1990)

To gain insight into the coupling mechanism of inhibitory receptors, 5-hydroxytryptamine1A receptors and alpha 2-adrenoceptors, with GTP-binding proteins (G proteins) in the central nervous system, we examined the effects of two 3-nitro-2-pyridinesulfenyl com...

Boc-Cys(Npys)-OH (BCNP): an appropriate reagent for the identification of T cell epitopes in cystine and/or cysteine-containing proteins.

J. Immunol. Methods 171(1) , 65-71, (1994)

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 appropr...
