Abstract:
A new platinum derivative of the form H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] (Hdigly==glycylglycine) damaged the Candida albicans cell membrane and inhibited the growth of the cells. The cytotoxic activity of H[Pt(IV)(Hdigly)Cl(2)(OH)(2)] on mammalian cells was 10-fold lower than that of cis-diammine-dichloroplatinum (cisplatin). Substitution of platinum for peptides is effective for enhancement of antifungal activity and reduction of the toxicity to mammalian cells.
