Rhodium(III) complexes with polypyridyls and pyrazole and their antitumor activity
摘要:
Synthesis and properties of rhodium complexes with nitrogen ligands [RhCl2(Hpz)(4)][RhCl4(Hpz)(2)] (1), [RhCl3(tpy)] (2), [RhCl3(tpta)] . H2O (3) and [Rh(tpy)(2)(Him)]Cl-3 . 3H(2)O (4), have been described. X-ray structures of complexes 1-3 have been determined. IR, UV-Vis and H-1 NMR spectra of the complexes have been discussed. Cytostatic activity of the complexes against HCV29T tumor cells increases in the series: 1 < 3 < 2 < 4. The cytostatic activity of complex 4 is greater than that of cisplatin. Interaction of the complexes with DNA has been investigated. (C) 2002 Elsevier Science B.V. All rights reserved.
