Oxaliplatin Analogues with Carboxy Derivatives of Boldine with Enhanced Antioxidant Activity
Bioinorganic Chemistry and Applications, Volume 2015, Issue 1, 2015., 2015 A new oxaliplatin analog [Pt(dach)(L5)] (1) was synthesized and characterized as a continuation of a study of the previously reported [Pt(dach)(L6)] (2), where dach = (1R,2R)‐diaminocyclohexane, L5 = 3‐carboxyboldine, and L6 = 3‐carboxypredicentrine. Compounds 1 and 2 exhibited a substantially enhanced antioxidant activity compared to oxaliplatin (130 ...
