Bioorganic & medicinal chemistry letters, 2005•ElsevierTwo-arm branched mPEG (monomethoxy-polyethylene glycol) with different molecular
weights (Mn= 4000, 6000, 9400) was synthesized and used as carrier for immobilization of
cisplatin [cis-diammine (dichloro) platinum (II), CDDP]. As a contrast, CDDP modified with
linear mPEGs was also synthesized. All these polymeric drugs modified with branched
mPEG are water soluble and show higher cytotoxic activity against C6 human breast cancer
cells than cisplatin modified with linear mPEG with the same molecular weight. All the …

All the polymeric CDDP showed a much lower toxicity than the CDDP.
