Synthesis, Characterization, Molecular Docking and Cytotoxicity Studies of Bagasse Xylem Ferulate-Acrylamide/Methyl Methacrylate Composite

BXFL (bagasse xylem ferulate)-g-AM (acrylamide)/MAA (methyl methacrylate) was synthesized based on bagasse xylan(BX)-g-AM/MAA in 1-Butyl-3-methylimidazolium chloride ([Bmim] Cl) ion solution with Ferulic Acid (FL) as esterification agent. The various factors that were investigated influenced carboxylic acid ester substitution degree (DSC</sub>) of BXFL-g-AM/MAA. The structures of BXFL-g-AM/MAA were confirmed by IR, SEM and 1</sup>H NMR analysis. The cytotoxicity of BXFL-g-AM/MAA was investigated against twelve kinds of protein through Surflex-Dock Mode of Sybyl-X 2.0 software, and on three kinds of human cancer cells line and the human normal cells line were detected by MTT assay. It was shown that the maximum DSC</sub> was 1.09 in ion solution, which was superior to DSC </sub>of conventional method in organic solvent. The results of MTT assay were consistent with docking results. BXFL-g-AM/MAA exhibited relative high cytotoxicity against human gastric cancer cells (MGC-803) line.
