Chemical structure of Boc-Cys(NPys)-OH

GA20924

Boc-Cys(NPys)-OH

Also known as (2R)-2-[(2-methylpropan-2-yl)oxycarbonylamino]-3-[(3-nitro-2-pyridinyl)disulfanyl]propanoic acid

Npys allows site-directed disulfide bond formation, as it is cleaved by thiols· Galande and Spatola obtained disulfide heterodimers of peptides via coupling Boc-Cys(NPys)-OH together with Fmoc-Cys(Mmt)-OH (B-2540) to MBHA-resin followed by Mmt removal with 1% TFA in dichloromethane·Mourier et al· used BCNP for the identification of T-cell epitopes in Cys and/or Cyt-containing proteins
