title: Design, synthesis and biological evaluation of (E)-3-(3,4-dihydroxyphenyl)acrylylpiperazine derivatives as a new class of tubulin polymerization inhibitors.
abstract: A series of novel (E)-3-(3,4-dihydroxyphenyl)acrylylpiperazine derivatives had been synthesized and evaluated their biological activities as potential tubulin polymerization inhibitors. Among these compounds, compound 3q exhibited potent antiproliferative activities against three cancer cell lines in vitro, and antitubulin polymerization activity with IC₅₀ of 0.92 μM, which was superior to that of colchicine (IC₅₀=1.34 μM). Docking simulation was performed to insert compound 3q into the crystal structure of tubulin at colchicine binding site to determine the probable binding model. These results suggested that compound 3q may be a promising antitubulin agent for the potential treatment of cancer.
