 Title    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.

 Title    New Botrydial Sesquiterpenoids from Hymenoscyphus epiphyllus  
 Abstract    Four new botrydial derivatives, hymendial (1), 7a-hydroxydihydrobotrydial (2), 701-hy­ droxy-10-0-methyldihydrobotrydial (4), and 7a-acetoxy-15a-methoxy-10-0-methyl-dihydro-botrydial (5) were isolated together with dihydrobotrydial (3) from the culture fluid of the ascomycete Hymenoscyphus epiphyllus. In addition, cytochalasin H (6a), 18-deoxycytocha-lasin H (6b) and (+)-mellein (7) were produced by this fungus. Hymendial (1), possessing an a, ß-unsaturated dialdehyde functionality, exhibits antimicrobial and cytotoxic activities and is mutagenic in the Ames Salmonella assay.
