Macromolecular Design of Platinum Drug Conjugates

Abstract

Cisplatin and its analogues display common drawbacks such as unfavorable toxicological profile, short blood circulation time and non-specific bio-distribution. Besides that, in biological fluids cisplatin is inactivated by nitrogenand sulphur-containing biomolecules. Drug conjugation to a water soluble polymer is a feasible approach to enhance therapeutic efficiency. Examples of carboxylate-containing polymer carriers of cisplatin and the effect of macromolecular architecture on the behavior of conjugates are discussed.
