Prostate cancer platinum complexes

Pt(TV) Prodrugs. Platinum(IV) complexes have been widely studied as potential prodrugs that avoid the limitations of the cisplatin class of anticancer drugs. Indeed, the Pt(IV) compound satraplatin [Pt(cha)Cl2(OAc)2(NH3)] (cha, cyclohexylamine) is currently in clinical trials for treatment of hormone-refractory prostate cancer (Fig. 1) (22). Satraplatin is the first orally bioavailable platinum derivative under active clinical investigation and is particularly attractive because of the convenience of administration, milder toxicity profile, and lack of cross-resistance with cisplatin. These results are promising and support the idea that platinum(IV) complexes offer the opportunity to overcome some of the problems associated with cisplatin and its analogs.
