  A DEAE-dextran-MMA copolymer (DDMC)–paclitaxel complex was generated using paclitaxel as the guest and DDMC as the host. The resulting nanoparticles were 200-300 nm in diameter and are thought to be useful as an anti-cancer drug delivery system because of forming a stable polymeric micelle in water. The resistance of B16F10 melanoma cells to paclitaxel was confirmed using survival curve analysis. On the other hand, there is no resistance of melanoma cells to DDMC–paclitaxel complex. The DDMC–paclitaxel complex showed superior anti-cancer activity to paclitaxel alone. The cell death rate was determined using Michaelis–Menten Equations, as the complex promoted allosteric supramolecular reaction to tubulin. From our results, the DDMC–paclitaxel complex was not extensively degraded in cells, and achieved good efficacy as an intact supramolecular anti-cancer a.. View More»
