He. Howardlock et al., CONCERNING THE NATURE OF THE GOLD-CONTAINING ANTIARTHRITIC DRUG, MYOCHRYSINE, Chemical communications, (11), 1996, pp. 1391-1392
An ammonium analogue of the main component of the anti-arthritic drug
myochrysine, disodium thiomalato-S-aurate(I) polymer, is examined by b
oth positive- and negative-ion electrospray ionization (ESI) mass spec
trometry; the principal peaks are those of a tetrameric species; subse
quent examination of a drug sample by the same technique showed that t
he principal peaks were also those of a tetrameric species.
