Effect of platinum(II) complexes of benzoic and 3-methoxybenzoic acid hydrazides on Saccharomyces cerevisiae

, : Effect of platinum(II) complexes of benzoic and 3-methoxybenzoic acid hydrazides on Saccharomyces cerevisiae. Zeitschrift für Naturforschung. C, Journal of Biosciences 50(9-10): 732-734

The inhibitory effect of benzoic acid hydrazide (bah) and 3-methoxybenzoic acid hydrazide (mbah) on Saccharomyces cerevisiae strains has been compared to that of their platinum(II) complexes: cis-[Pt(mbah)2X2], cis-[Pt(NH3)(mbah)Cl2].0.5 H2O, cis-[Pt(mbah)2X2] and cis[Pt(NH3)(mbah)Cl2] (mean = Cl, Br = I), and cis-[Pt(NH3)2Cl2]. The minimal inhibitory concentrations for bah and mbah were 5000-20,000 microM whereas for their Pt(II) complexes they were much less (25-800 microM) and did not exceed these of cisplatin (100-800 microM). The activity of the Pt(II) complexes of bah and mbah varied in wide ranges for the different yeast strains tested. Osmotically unstable mutants were found to be more susceptible. The most active complexes were [Pt(NH3)(bah)Cl2].0.5 H2O and [Pt(NH3)(mbah)Cl2].
