Eighteen Se-substituted selenocysteine derivatives were synthesized as potential kidney selective prodrugs which can be activated by renal cysteine conjugate beta-lyase to selenium-containing chemoprotectants or antitumor agents. Selenocysteine derivatives with aliphatic and benzylic Se-substituents were synthesized by reducing selenocystine to selenocysteine followed by a reaction with the corresponding

cysteine derivatives in solid phase peptidesynthesis, there is a striking paucity of analogous selenocysteine Se‐protecting groups in the literature. However, the growing interest in selenocysteine‐containing peptides and proteins requires a corresponding increase in availability of syntheticroutes into these target molecules. It therefore becomes important to design new sidechain protection strategies

Targeted insertion of a non‐native diselenide cross‐link into a cysteine‐rich protein can be exploited to direct the early stages of oxidativefolding so as to avoid accumulation of unproductive intermediates that limit folding efficiency. This simple strategy could facilitate the production of many difficult‐to‐fold peptides and proteins.

A strategy for the synthesis of de novo discovered lactazole-like thiopeptides is reported. The approach revolves around a convergent and scalable preparation of the central triheterocyclic amino acid and its utilization in Fmoc solid-phase peptidesynthesis for modular peptide chain assembly. A technique for preparing C-terminally functionalized thiopeptides for biological studies is also described
