A series of ferrocenyl and ruthenocenyl conjugates with colchicine bearing a 1,2,3-triazole moiety were synthesized and their anticancer properties were evaluated. We found that the most potent metallocenyl derivatives Rc4 and Rc5 are 6–7 times more cytotoxic toward HepG2 cells, while Fc4 and Fc5 are two times more cytotoxic toward HCT116 cells as colchicine. We also found that compounds Fc4, Fc5,
Synthesis and Biological Activity of Ferrocenyl and Ruthenocenyl Analogues of Etoposide: Discovery of a Novel Dual Inhibitor of Topoisomerase II Activity and Tubulin Polymerization
Two series of the ferrocenyl and ruthenocenyl analogues of etoposide bearing 1,2,3‐triazolyl or aminoalkyl linker were synthesized and evaluated for their cytotoxic properties, influence on the cell cycle, ability to induce tubulin polymerization, and inhibition of topoisomerase IIactivity. We found that the replacement of the etoposide carbohydrate moiety with a metallocenyl group led to organometallic
