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 II activity. We found that the replacement of the etoposide carbohydrate moiety with a metallocenyl group led to organometallic conjugates exhibiting differentiated antiproliferative activity. Biological studies demonstrated that two ferrocenylalkylamino conjugates were notably more active than etoposide, with submicromolar or low-micromolar IC50 values towards SW620, etoposide-resistant SW620E, and methotrexate-resistant SW620M cancer cell lines. Moreover, the simplest ferrocenylmethylamino conjugate exerted dual inhibitory action against tubulin polymerization and topoisomerase II activity while other studied compounds affected only topoisomerase II activity.

A series of novel 4β-[(5-substituted)-1,2,3,4-tetrazolyl] podophyllotoxin derivatives were synthesized by employing azide-nitrile click chemistry approach. All the derivatives were evaluated for their cytotoxicity against a panel of four human cancer cell lines and their IC50 values were found to be in the range of 2.4-29.06 μM. The cytotoxicity exhibited by the majority of test compounds were found to comparable and often more effective than doxorubicin and all compounds exhibited higher cytotoxicity on A-549 cell lines. Cell cycle analysis showed that the novel 4β-[(5-substituted)-1,2,3,4-tetrazolyl] podophyllotoxins resulted in cell cycle arrest at G2/M phase and were also found to be the potent inhibitors of tubulin polymerization in vitro.
