[Direct transition of S-acetamidomethyl-protected peptide 593-603 of HIV-2 gp41 into a cyclic disulfide using iodine. Study of side reactions].
Removal of Acm-protecting group from thiol functional groups of Cys residues with simultaneous disulfide bridge formation by iodine in acetic acid was studied in the course of the synthesis of a pepti...Read More
Side reaction of S-to-N acetamidomethyl shift during disulfide bond formation by iodine oxidation of S-acetamidomethyl-cysteine in a glutamine-containing peptide.
During the time course of disulfide bond formation by iodine oxidation (in a methanolic and hydrochloric acid solution) of a cysteinyl(S-acetamidomethyl)-glutaminyl tridecapeptide, we observed by ESI,...Read More
Deprotection of S-acetamidomethyl cysteine-containing peptides by silver trifluoromethanesulfonate avoids the oxidation of methionines.
We're sorry this abstract is currently not available....Read More
Side reaction during the deprotection of (S-acetamidomethyl)cysteine in a peptide with a high serine and threonine content.
The acetamidomethyl (Acm) group is a widely used protecting group for the thiol of cysteine during the SPPS process. We prepared the amino terminal loop of the snake alpha-neurotoxin, [Cys3,Cys23, Ser...Read More
A 34-amino acid synthetic peptide was derived from the third domain of human alpha-fetoprotein, and the peptide was shown to inhibit estrogen-stimulated growth. Under certain conditions, however, the ...Read More
