Description and Uses

S-Trityl-cysteine (2799-07-7) is a cell permeable inhibitor of mitotic kinesin Eg5 (IC50 for inhibition of basal ATPase activity = 1 μM; IC50 for inhibition of microtubule-activated ATPase activity = 140 nM). Mean growth concentration (GI50) of 1.31 μM for a panel of 60 different tumor cell lines.

(+)-S-Trityl-L-cysteine, a non-natural, sulfur-containing amino acid is commonly used as a reagent in solution phase peptide synthesis (SPPS). It is also used as a metal-binding agent to synthesize substituted ferrocenoyl peptide conjugates using HBTU peptide coupling reagent for the cation-sensing applications solution via peptide-metal interactions.
