 |  | FMOC-S-trityl-L-cysteine Usage And Synthesis |  
 | Chemical Properties | white to light yellow crystal powde |  | Uses | 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.
 
 
  |  | Uses | It is potentially useful for proteomics studies, and solid phase peptide synthesis techniques. Cysteine is versatile amino acid involved with many biological processes, including the formation of disulfide bonds - a critical component of protein structure. This compound could be useful as an unusual amino acid analog to aid in the deconvolution of protein structure and function. |  | General Description | The standard derivative for Fmoc SPPS of peptides containing Cys [1]. The Trt group is removed with 95% TFA containing 1-5% TIS. Ideally, this derivative should be introduced using the symmetrical anhydride or DIPCDI/HOBt activation [2,3] to minimize enantiomerization. If activation with uronium or phosphonium reagents, such as HBTU or PyBOP?, is to be employed, it is strongly recommended that collidine is used as the base [4], as this has been shown to significantly reduce loss of optical integrity during coupling.
