Descrizione generale

The 3-nitro-2-pyridinesulphenyl (Npys) moiety is useful as a protecting-activating group for cysteine, particularly in the synthesis of cyclic and unsymmetrical disulfides. The stability of NpysCl was studied in various solvents.

Applicazioni

3-Nitro-2-pyridinesulfenyl chloride (NpysCl) was employed as the starting material for the synthesis of N-, O- and S-Npys-protected amino acid.

3-Nitro-2-pyridinesulfenyl chloride (NpysCl) is the starting material for the synthesis of N-, O- and S-Npys-protected amino acids. Two efficient, novel synthetic routes to NpysCl are described. The stability of NpysCl was determined in a variety of solvents, with and without

The thiol groups of leucinthiol, cysteamine and cysteine incorporated into opioid peptides enkephalin and morphiceptin were activated by the 3-nitro-2-pyridinesulphenyl (Npys) group to form mixed disulphides highly reactive to a free thiol. Enkephalin analogues containing Npys-leucinthiol or -cysteine at positions

The inhibitory capacity of C-Npys (S-[3-nitro-2-pyridinesulfenyl]) derivatives over thiol-containing serine proteases has never been tested. In the present work we used an extracellular serine-thiol proteinase activity from the fungal pathogen Paracoccidioides brasiliensis (PbST) to describe a potent inhibitory capacity of

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 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
