Hazard Information | Back Directory | [Description]
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. | [Chemical Properties]
almost white to light yellow granular powder | [Uses]
(+)-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. | [Uses]
A protected cysteine for peptide synthesis. S-Trityl-L-cysteine (STLC) is a tight-binding inhibitor of Eg5 that prevents mitotic progression. It has proven antitumor activity as shown in the NCI 60 tumor cell line screen. | [Uses]

ChEBI: (2R)-2-amino-3-[(triphenylmethyl)thio]propanoic acid is a benzenoid aromatic compound. | [Biological Activity]
Potent, cell-permeable, selective inhibitor of mitotic kinesin Eg5, a protein required for establishing and maintaining a bipolar spindle. Inhibits basal ATPase activity (IC 50 = 1 mM) and microtubule-activated ATPase activity of Eg5 (IC 50 = 140 nM). Induces mitotic arrest in HeLa cells with an IC 50 of 700 nM. Displays antitumor activity. | [storage]
