✦ Synopsis


Mouse calvaria were maintained in organ culture without serum additives. The effects of three gold complexes--aurothioglucose, aurothiomalate, and auranofin--on active bone resorption (45Ca release) and hydroxyproline synthesis were determined. The influence of these compounds on DNA and protein synthesis and lysosomal enzyme release from calvaria was also assessed. All gold complexes reduced bone resorption to some extent, with auranofin being the most potent within a narrow concentration range (10(-6) M). This concentration of auranofin also significantly inhibited collagen synthesis, although DNA and protein synthesis were unaffected. None of the compounds tested appeared to mediate their action via significant inhibition of lysosomal enzyme release.
