Abstract

The relevant adsorption of cis-[Pt(NH3)2(P2O7)](2-) (phosphaplatin) on hydroxyapatite nanocrystals (nHAP) was observed and studied in water suspension. Phosphaplatin cytotoxicity, which is very low for HeLa, MCF-7 and HS-5 cell lines could be enhanced, reaching that of cisplatin, by interaction with solid nHAP. This effect stems from nHAP ability to catalyze the phosphaplatin hydrolysis, producing the same hydrolytic species responsible for cisplatin antitumor activity.
