Description

General description

Fmoc-Cys(Trt)-OH is an amino acid commonly used in the Fmoc solid-phase peptide synthesis.

Application

Fmoc-Cys(Trt)-OH is an N-terminal protected cysteine derivative used in peptide synthesis. Some of the examples are:

• Synthesis of mono- and bi-functionalized platinum(IV) complexes to target angiogenic tumor vasculature.
• Synthesis of proteins through native chemical ligation of peptide hydrazides as thioester surrogates via solid-phase synthesis.
• Synthesis of glycoconjugates by conjugating reducing sugars to cysteine residues of peptides.
