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

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

The 3-nitro-2-pyridinesulphenyl (Npys) moiety is finding increasing utility as a protecting-activating group for cysteine, particularly in the synthesis of cyclic and unsymmetrical disulfides using the Boc strategy. This chemistry has been extended to peptides assembled by the Fmoc strategy. N-Terminal

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

Thrombin-induced platelet aggregation has been suggested to play an important role in reocclusion following thrombolytic therapy or angioplasty for treatment of myocardial infarction. We previously demonstrated that thrombin-induced platelet aggregation is indirectly mediated by intracellularly activated calpain expressed on the
