The invention provides an organotin-oxygen cluster containing ferrocene pyrazole. The cluster is characterized in that the complexes with the following chemical formulas are prepared from a ligand 3-trifluoromethyl-5-ferrocene pyrazole acetic acid (LCOOH) and monobutyltin oxide, dibutyltin oxide and triphenyltin hydroxide respectively: [BuSnO(OOCL)]6, [Ph4Sn2O(OCH3)(OOCL)]2 and [Bu4Sn2O(OOCL)2]2. The cluster has inhibiting effects on human lung cancer cells (A549), hepatoma cells (HepG2) and mouse melanoma (B16-F10) and the inhibiting effects are obviously superior to the inhibiting effects of the control drugs 5-fluorouracil and cisplatin, so the cluster can be applied to preparing the anti-tumor drugs. |
