Cisplatin and some of its derivatives are among the most active cytostatics for cancer treatment. Unfortunately, application of platinum complexes always indicates side effects, and frequently primary or developed resistance of tumour cells appear. Therefore, development of novel analogues especially with natural ligands is expedited. Glyco-functionalized ligands were obtained via ether synthesis with ?-halo ethers, Finkelstein reaction, with further treatment with malonate and final deprotection followed by preparation of the disodium salts. Subsequent complexation led to novel platinum derivatives, the stabilities of which in aqueous solution media were studied.
