Two series of ferrocenyl chalcones were synthesized and evaluated for in vitro antiamoebic activity against HM1:IMSS strain of Entamoeba histolytica. The results showed that compounds of series B having ferrocene ring adjacent to carbonyl linkage were generally more active than compounds of series A. Compounds having unsubstituted phenyl ring, methoxy substitution, thiomethyl group, chloro group and nitro group, exhibited better antiamoebic activity than the reference drug metronidazole. The toxicological studies of these compounds on human kidney epithelial cell line showed that all compounds were non-toxic. The compound 1-ferrocenyl-3-(4-nitrophenyl)-2-propen-1-one (18) was found most active and least toxic among all compounds.
