The plant derivative steganacin, an antitumor compound, blocks the replication of HeLa cells in mitosis. Steganacin inhibits microtubule assembly in vitro (ID50 = 1.5 μM) and is a competitive inhibitor of colchicine binding to purified tubulin (Ki = 3.1 μM). The structure-activity relationships of steganacin and a series of analogues are reported.
