The application of sulfur-containing peptides in drug discovery

In recent decades, peptides as potential drugs were more and more explored with the development of non-oral medicine. There into, sulfur-containing peptide is one of the most popular aspects in peptide drugs due to the introduction of sulfur atoms leading unique properties. The purpose of the present review is to focus on the discovery of various sulfur-containing peptides with particular emphasis on their pharmacological mechanisms. This review is organized according to the structures of the sulfur-containing peptides.
