3-(3-Phenoxybenzyl)amino-β-carboline: A novel antitumor drug targeting α-tubulin
摘要:
3-(3-Phenoxybenzyl)amino-beta-carboline 2h showed extremely-high activity; the IC(50) value was 0.074 mu M. To verify 2h-induced cell death types, we observed the chromatin condensation, the DNA fragmentation and activated caspase-3 using Hoechst 33342, agarose electrophoresis and western blot, and suggesting 2h-induced cell death type was apoptosis. Flow cytometry showed that 2h-treated cell was induced SubG1 cell population after G2/M cell cycle arrest. In addition, using affinity chromatography and peptide mass fingerprinting, we found that interacting protein with this compound was a-tubulin protein. (C) 2011 Elsevier Ltd. All rights reserved.
