Abstract
A series of novel arylantimony ferrocenylcarboxylate derivatives with the formulae [C5H5FeC5H4C(CH 3)=CHCOO]2SbAr3 and [4-(C5H 5FeC5H4)C6H4COO] 2SbAr3 (Ar = C6H5, 4-CH 3C6H4, 4-ClC6H4, 4-FC6H4) were synthesized and characterized by elemental analysis, IR and 1H NMR. The crystal structures of [C 5H5FeC5H4C(CH3)=CHCOO] 2Sb(C6H4F-4)3 and [4-(C 5H5FeC5H4)C6H 4COO]2Sb(C6H4F-4)3 were determined by X-ray diffraction. The two sets of crystal X-ray data show that the antimony atom of the former has a special six-coordinate geometry while that of the latter has a general five-coordinate geometry. Three human neoplastic cell lines (HCT-8, Bel-7402 and KB) were used to screen these compounds. The results indicate that [C5H5FeC 5H4C(CH3)=CHCO2]2 Sb(C6H4Cl-4)3 and [C5H 5FeC5H4C(CH3)=CHCO2] 2Sb(C6H4F-4)3 at 5 μM show relatively good in vitro antitumor activities.
