Design and synthesis of ferrocenyl 1,4-dihydropyridines and their evaluation as kinesin-5 inhibitors

Abstract

Kinesin-5 inhibitors offer cancer cell-targeted approach, thus securing reduced systemic toxicity compared to other antimitotic agents. By modifying the 1,4-dihydropyridine-based kinesin-5 inhibitor CPUYL064 with a ferrocenyl moiety (Fc), we designed and prepared a series of organometallic hybrids that show high antiproliferative activity, with the best compounds exhibiting up to 19-fold increased activity. This enhanced activity can be attributed to the presence of the ferrocenyl moiety.
