- Abstract
- 31P nuclear magnetic resonance and electrospray ionization-mass spectrometry studies on the melanoma
cytotoxic chlorotriphenylphosphine-1,3-bis(diphenylphosphino)propanegold(I), [Au(DPPP)(PPh3)Cl], show
partial decomposition that includes the novel dinuclear cation [Au2(DPPP)2Cl]+; its structure was calculated
by using the density functional theory (DFT). Unexpectedly, by using the diphosphine ligand 1,2-
bis(diphenylphosphino)ethane (DIPHOS), [{AuCl(PPh3)}2(?2-DIPHOS)] was obtained. Its X-ray crystal
structure shows a unique triangular coordination sphere in contrast to the T-shaped geometry of related
Au(I)-DIPHOS compounds. Its cytotoxic activity in JR8, SK-Mel-5, and 2/60 melanoma cell lines is dose-dependent
and lower than that of [Au(DPPP)(PPh3)Cl] because of its nonchelating nature. An in vitro study
of the effect of both Au compounds on the B16V melanoma cell line gives credence to this structure-activity
relationship. IC50 indicates that both Au species are 10 times more active in B16V than in JR8, SK-Mel-5,
and 2/60. Oxidation of [Au(DPPP)(PPh3)Cl] toward Au(III) compounds and phosphine-oxides is observed
upon reaction with hypochlorite in water/dimethyl sulfoxide solution, mimicking endogenous hypochlorite.
A related reaction involving the formation of [AuCl4]- is thermodynamically feasible according to DFT
