Use of the 3-nitro-2-pyridine sulfenyl protecting group to introduce N epsilon-branching at lysine during solid-phase peptide synthesis. I. Application to the synthesis of a peptide template containing two addressable sites.

S Rajagopalan et al.

International journal of peptide and protein research, 45(2), 173-179 (1995-02-01)

TASPs (template-assembled synthetic peptides) are generated by the covalent attachment of linear peptides to a common peptide backbone, thus generating larger synthetic peptides/proteins with prefolded structure. In this work we present a strategy for the synthesis of a heterotemplate-assembled synthetic

Compatibility of the S-(3-nitro-2-pyridinesulfenyl) protecting group with DCC/HOBt coupling chemistry.

R Matsueda et al.

Peptide research, 5(5), 262-264 (1992-09-01)

Two recent reports on the partial lability of the 3-nitro-2-pyridinesulfenyl (Npys) thiol protecting group towards 1-hydroxy-benzotriazole (HOBt) have prompted a rechecking of the chemical behavior of this group. Using both soluble and polymer-bound forms of Cys(Npys) as test materials, the

Thiolysis of the 3-nitro-2-pyridinesulfenyl (Npys) protecting group. An approach towards a general deprotection scheme in peptide synthesis.

O Rosen et al.

International journal of peptide and protein research, 35(6), 545-549 (1990-06-01)

The hydroxylic side-chain functional groups of serine, threonine, hydroxproline and tyrosine, the alpha and epsilon-amino moieties of lysine and the thiol group of cysteine were masked by the 3-nitro-2-pyridinesulfenyl (Npys) protecting group. Deprotection was mildly affected by thiolysis with either
