to show potent in vitro anticanceractivity comparable to cisplatin and oxaliplatin; especially DN604, which exhibited low acute toxicity similar to carboplatin, and presented acceptable solubility and stability in water. Chemical and biological results indicated that the functionalized moiety, uncoordinated, led to potentanticanceractivity and low apparent toxicity of the platinumcomplexes by affecting

Four water-soluble dia(m)mine platinum complexes with 3-oxo-cyclobutane- 1,1-dicarboxylate as the leaving group have been synthesized. These compounds were evaluated for their in vitro anticancer activity against three human A549, SK-OV-3, and HT-29 cancer cell lines. All the tested compounds showed potent activity in lung carcinoma (A549), ovarian carcinoma (SK-OV-3), and colon cancer cell (HT-29) lines. Complex 2(IC50 value = 1.57 µM for A549 and IC50 value = 0.88 µM for HT-29 cells) and Complex 4 (IC50 value = 15.3 µM for SK-OV-3 cells) displayed the most potent anticancer activity of the series. Also, preliminary acute toxicity of the platinum complexes derivatives has shown the same level as carboplatin and lower toxicity than cisplatin in vivo. All the complexes were characterized by elemental analysis as well as by ESI+-MS, FT-IR, 1H- and 13C-NMR, and have shown a satisfactory water solubility.
We describe herein the synthesis of a series of carboplatin derivatives with different functional groups at position 3 of the cyclobutane ring. This pharmacomodulation approach aims at facilitating the vectorisation of these analogues, via their subsequent conjugation to a drug delivery system. Five different derivatives bearing a hydroxy, keto, iodo, azido or amino function at position 3 were synthesised
