| 20110021483 | Platinum (IV) Complexes - Provided are nitroplatinum(IV) complexes containing a bidentate dicarboxylate ligand (e.g., oxalate) which maybe useful treating various forms of proliferative diseases, such as cancer. In some instances the platinum(IV) complexes are relatively stable and may be suitable for oral administration. Also provided are methods of treatment, as well as kits and unit dosages. | 01-27-2011 |
| 20100184854 | PLATINUM (IV) COMPLEXES AND METHODS OF USE THEREOF - Provided are nitroplatinum(IV) complexes which may be useful treating various forms of proliferative diseases, such as cancer. In some instances the platinum(IV) complexes are relatively stable and may be suitable for oral administration. Also provided are methods of treatment, as well as kits and unit dosages. | 07-22-2010 |
| 20090312417 | PLATINUM(II) COMPLEXES, PREPARATION AND USE - The invention relates to a method for the preparation of platinum (II) complexes, in particular dicarboxylatoplatinum (II) complexes containing a neutral bidentate ligand, such as oxaliplatin. The method includes the step of reacting a bis-dicarboxylatoplatinate (II) species with a suitable neutral bidentate ligand to form a neutral dicarboxylatoplatinum (II) complex and, if necessary, recrystallising the product to form a pure dicarboxylatoplatinum (II) complex containing a neutral bidentate ligand. The invention also relates to a method for producing a bis-dicarboxylatoplatinate (II) species, and to new platinum (II) complexes that can be made by the method of the invention. | 12-17-2009 |
| 20090299085 | PREPARATION OF PLATINUM(II) COMPLEXES - This invention relates to a method for the preparation of a platinum(II) complex containing a neutral bidentate ligand, such as oxaliplatin. The method includes the step of reacting a halogenoplatinum complex containing a neutral bidentate ligand with an oxalate salt in a solvent, wherein more then 1 g/L of the oxalate salt is soluble in the solvent. The invention also relates to new platinum(II) complexes. | 12-03-2009 |
| 20090281319 | PREPARATION OF PLATINUM (II) COMPLEXES - This invention relates a method for the preparation of platinum(II)oxalato complexes from their dihalogenoplatinum(II) precursors having either neutral monodentate or bidentate non-leaving co-ligands. Of particular interest is oxaliplatin. The method includes the step of reacting a halogenoplatinum(II) complex containing a neutral monodentate or bidentate ligand with an oxalate in a non-aqueous solvent or a mixed solvent system. The mixed solvent system is solvent mixture containing a non-aqueous solvent and water. According to the present invention, the non-aqueous solvent is an alcohol. | 11-12-2009 |
