Biochemical analysis of cellular target of S-trityl-L-cysteine derivatives using affinity matrix.
Biochemical analysis of the cellular target of S-trityl-l-cysteine (STLC) derivatives was performed by using the newly synthesized STLC derivative-immobilized affinity beads (3d). The affinity beads efficiently captured KSP in HCT116 cytoplasmic cell lysate. The results obtained from pull-down and competition experiments using 3d with STLC derivatives provided the first evidence for direct interaction of these derivatives with KSP in cancer cells. Design, synthesis and application of 3d were reported.
