Water-Soluble Cp Ruthenium Complex Containing 1,3,5-Triaza-7-phosphaadamantane and 8-Thiotheophylline Derivatives: Synthesis, Characterization, and Antiproliferative Activity
摘要:
The new water-soluble ruthenium(II) mononuclear complexes [RuCp(X)(PTA)(L)] (X = 8-thio-theophyllinate (TTH-), L = PTA (1), L = PPh3 (7)); (X = 8-methylthio-theophyllinate (8-MTT-), L = PTA (2), L = PPh3 (8)), (X = 8-benzylthiotheophyllinate (8-BzTT(-)), L = PTA (3), L = PPh3. (9)) and binuclear complexes [{RuCp(PTA)(L)}(2)-mu-(Y-kappa N7,N'7)] (Y = bis(S-8-thiotheophyllinate)methane (MBTT2-), L = PTA (4), L = PPh3 (10)), (Y = 1,2-bis(S-8-thiotheophyllinate)ethane (EBTT2-), L= PTA (5), L=PPh3 (11)), (Y=1,3-bis(S-8-thiotheophyllinate)propane (PBTT2-); L = PTA (6), L=PPh3 (12)) have been synthesized and characterized by NMR, IR spectroscopy and elemental analysis. The single crystal X-ray structure of [RuCp(8-MTT-kappa S)(PTA)(2)] (2) was also obtained. The antiproliferative activity of the complexes on cisplatin-sensitive T2 and cisplatin-resistant SKOV3 cell lines has been evaluated.
