Wang S, Wang Q, Wang Y, Liu L, Weng X, Li G, Zhang X, Zhou X: Novel anthraquinone derivatives: synthesis via click chemistry approach and their induction of apoptosis in BGC gastric cancer cells via reactive oxygen species (ROS)-dependent mitochondrial pathway. Bioorg Med Chem Lett. 2008 Dec 15;18(24):6505-8. Epub 2008 Oct 14.
Three water soluble anthraquinone derivatives were designed and synthesized employing click chemistry to prepare novel and potent antitumor drugs. An MTT assay indicated that all compounds had significant inhibitory activity against BGC gastric cancer cells in vitro. Apoptosis induced by these compounds was observed by flow cytometry and laser confocal microscopy. Mechanistic analysis showed that these compounds induced the generation of several reactive oxygen species, the loss of mitochondrial membrane potential (Delta psi m), the transition of mitochondrial permeability, and the release of cytochrome C from the mitochondrion to cytoplasm. These results suggest that the anthraquinones might be potential lead compounds for the cancer chemotherapy. |
