Aziridine-mediated ligation and site-specific modification of unprotected peptides
Dyer, Frank Brock,Park, Chung-Min,Joseph, Ryan,Garner, Philip
, p. 20033 - 20035 (2012/01/31)
A synthesis of aziridine-containing peptides via the Cu(II)-promoted coupling of unprotected peptide thioacids and N-H aziridine-2-carbonyl peptides is reported. The unique reactivity of the resulting N-acylated aziridine-2-carbonyl peptides facilitates t
Ribozymomimetic chemical synthesis of peptide bond using phosphorous acid/oxirane mediators
Bayryamov,Danalev,Vassilev
experimental part, p. 338 - 344 (2011/04/24)
Chemical Equation Presented A model system is created that mimics natural ribosome as well as the way of ribozyme action. It uses oxirane analogue as condensation reagent and H3PO3 as activator for the carboxyl group and as protecting reagent for the NH2
2,2-Dimethyl-2-(o-nitrophenyl)acetyl (DMNA) as an assisted cleavage protecting group for amines
Jiang, Yongying,Zhao, Jun,Hu, Longqin
, p. 4589 - 4592 (2007/10/03)
2,2-Dimethyl-2-(o-nitrophenyl)acetyl group (DMNA) was explored as an assisted cleavage protecting group for amines and a one-step deprotection condition was developed for its efficient removal using hydrogenation in the presence of Pd-C or PtO2 catalyst and 10% HOAc in MeOH. DMNA was found to be especially useful for the synthesis of gem-diamino compounds using Hofmann rearrangement.
Synthesis and opioid activity of tyrosine sulfate containing dermorphin and deltorphin peptides
Marastoni,Salvadori,Balboni,Scaranari,Borea,Tomatis
, p. 116 - 119 (2007/10/02)
To study the effect of the sulfate ester moiety on the opioid activity, we prepared two tyrosine sulfate-(Tyr(SO3H))-containing dermorphin and deltorphin peptides. Their activities were determined in binding studies based on displacement of μ-
