Abstract
A series of ionic phosphorus ylide complexes of gold(I) halides has been prepared and characterized through analytical and spectroscopic data. The compounds are of the type [R3PAu-CH2PR3]⊕Cl⊖, R = C2H5, and [(R3PCH2)2Au]⊕X⊖ where R = CH3, C2H5, n-C4H9, C6H5, and X = Cl, Br (1-6). Along with a cyclic complex [(C2H5)2P(CH2)2Au]2 (7) these materials have been tested in a pharmacological study for a possible use in an oral arthritis therapy. Compounds 1 and 5-7 showed no or only neglegible effects on Adjuvans-arthritis induced in rats, while 3 and 4 were very toxic. Complex 2 was comparable to standard chrysotherapeutic agent3 in a preliminary study, but a more detailed investigation including LD50 tests for mice showed too narrow a gap between its toxical and therapeutically useful doses.Keywords
