Application

(+)-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.

The mitotic kinesin Eg5 is critical for the assembly of the mitotic spindle and is a promising chemotherapy target. Previously, we identified S-trityl-L-cysteine as a selective inhibitor of Eg5 and developed triphenylbutanamine analogues with improved potency, favorable drug-like properties, but

Mitotic kinesins represent potential drug targets for anticancer chemotherapy. Inhibitors of different chemical classes have been identified that target human Eg5, a kinesin responsible for the establishment of the bipolar spindle. One potent Eg5 inhibitor is S-trityl-L-cysteine (STLC), which arrests

The mitotic kinesin Eg5 plays an essential role in establishing the bipolar spindle. Recently, several antimitotic inhibitors have been shown to share a common binding region on Eg5. Considering the importance of Eg5 as a potential drug target for cancer
