Biohybrid –Se–S– Coupling Reactions of an Amino Acid Derived Seleninate

Professor Spencer Knapp, Zhexun Sun, and Mohannad Abdo describe the synthesis of the N-(2-seleninatoethyl) amide of N-Boc-phenylalanine, serving here as a peptide model, and its click-type reductive coupling reactions under mild protic conditions with unprotected thiouridine and glutathione. Selenosulfide products such as these comprise reversibly conjugated bio-components, and can potentially find uses as probes of biological function, such as enzyme inhibitors, delivery systems, or structural mimics.
