Abstract Several amino acids and peptides containing thiazole and thiazolidine residues were prepared. They were tested in vivo and in vitro as possible antitrypanosomal compounds. Some derivatives showed a slight activity. As they are structurally related to glutathione, their inhibitory properties towards glutathionylspermidine synthetase, trypanothione synthetase and trypanothione reductase were determined. No inhibitory ...
