A new series of 6-ferrocenyl-4-aryl-2-substituted pyrimidines were synthesized and evaluated for in vitro antiamoebic activity against HM1:IMSS strain of Entamoeba histolytica. Out of 16 compounds 10 compounds have shown IC50 values in the range of 0.41-1.73 mu M and 1.80 mu M. Pyrimidine derivatives having thiomethyl group, chloro group and mono-, di-, and trimethoxy substitution, exhibited higher antiamoebic activity than the reference drug metronidazole (IC50 = 1.80 mu M). The toxicological studies of these compounds on human kidney epithelial cell line showed that all compounds were non-toxic. 4-(4-Chlorophenyl)-6-ferrocenyl-2-piperidin-1-yl-pyrimidine (4f) was found most active (IC50 = 0.41 mu M) and least toxic among all the compounds.
