S-Trityl-L-cysteine Chemical Properties,Usage,Production

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.

Definition

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

Store at +4°C
