摘要：

New catecholamine ruthenium(III) complexes with potentially interesting biological activity are described. The complexes were prepared by reacting catecholamine with [RuCl(NH3)(5)]Cl-2. The newly prepared species were formulated as [Ru-III(NH3)(4)(catecholamine-R)](n+) where catecholamine- R = noradrenaline, dopamine and isoproterenol, and were characterized by elemental analysis, e.p.r., electronic absorption and f.t.-i.r. They were moderately stable in water at room temperature for at least 1 week. In vitro tests of antifungal activity showed the ruthenium catecholamine complexes had strong inhibitory action against the pathogenic yeast Candida albicans, Candida glabrata and Candida tropicalis. Free catecholamine does not show any antifungal activity.
