Synthesis, characterization, and cytotoxicities of platinum(II) complexes bearing pyridinecarboxaldimines containing bulky aromatic groups
摘要:
Condensation of 2-pyridinecarboxaldehyde with several primary amines containing bulky aryl groups gave the corresponding pyridinecarboxaldimines (N-N'). Addition of these ligands to [PtCl2(coe)](2) (coe = cis-cyclooctene) gave complexes of the type cis-PtCl2(N-N') in moderate yields. The platinum complexes have been examined for their potential cytotoxicities against OV2008 (human ovarian carcinoma) and the analogous cisplatin-resistant cell line C13. (C) 2004 Elsevier B.V.
