WebTrypanothione is an unusual form of glutathione containing two molecules of glutathione joined by a spermidine ( polyamine) linker. It is found in parasitic protozoa such as leishmania and trypanosomes. [1] These protozoal parasites are the cause of leishmaniasis, sleeping sickness and Chagas' disease. Trypanothione was discovered by Alan Fairlamb. WebJul 23, 2024 · It is useful for S-arylation-mediated peptide cyclization, which results in the synthesis of an Amatoxin derivative and stapled peptide possessing a tryptathionine structure. Abstract Covalent linking of side chains provides a method to produce cyclic or stapled peptides that are important in developing peptide-based drugs.
