| Antibiotika aus Basidiomyceten, XV [1]. l-Hydroxy-2-nonin-4  | | | | Abstract
| on, ein antifungischer und cytotoxischer Metabolit aus Ischnoderma benzoinum (Wahl.) Karst. Antibiotics from Basidiomycetes. XV [1]. l-Hydroxy-2-nonyn-4-one, an Antifungal and Cytotoxic M etabolite from Ischnoderma benzoinum (W ahl.) Karst. A new antibiotic, 1-hydroxy-2-nonyn-4-one (1), has been isolated from submerged cultures of several strains of Ischnoderma benzoinum. The compound exhibits high inhibitory activity against yeasts and filamentous fungi at concentrations o f 1 -5 ng/ml. D N A , RNA, and protein syntheses in cells of the ascitic form o f Ehrlich carcinoma are strongly inhibited by the same concentrations. | | | |

| The Effect of Clotrimazole and Triadimefon on 3-Hydroxy-3-Methyl-Glutary 1-Co A-Reductase-[EC 1.1.1.341- Activity in Saccharomyces cerevisiae | | | | Abstract
| Clotrimazole and triadimefon are known as potent inhibitors of ergosterol synthesis in pathogenic yeasts and fungi, respectively. As their mode of action generally the inhibition of sterol desmethylation reactions is accepted. We report about a second effect, a "feed-back" inhibition of 3-hydroxy-3-methyl-glutaryl (HMG)-CoA-reductase by accumulation of ergosterol precursors. Addition of lanosterol to intact cells leads to an inhibition of HMG-CoA-reductase as well, but not to fungistatic effects. From the reported data the influences of clotrimazole and triadimefon have to be considered as an inhibition of desmethylation reactions involved in ergosterol synthesis of yeasts and fungi with a concomitant decreased production of mevalonate. | | | |
