    Abstract Prenyltransferases (PTs) are involved in the biosynthesis of a multitude of pharmaceutically and agriculturally important plant, bacterial, and fungal compounds. Although numerous prenylated compounds have been isolated from Basidiomycota (mushroom-forming fungi), knowledge of the PTs catalyzing the transfer reactions in this group of fungi is scarce. Here, we report the biochemical characterization of an

    Abstract Discopodium penninervium is a medicinal plant endemic to Ethiopia. Its twigs extract led to the isolation of three new withanolides, discopodinolides A - C, and four known analogues. The structures of the compounds were elucidated using NMR, HRMS data analyses, and literature data. The relative configurations were defined by single-crystal X-ray crystallography and NOESY correlations. The antibacterial efficacy of the isolated compounds was evaluated against four commonly dispersed environmental strains of Escherichia coli, Bacillus subtilis, Bacillus pumilus, and Bacillus megaterium. Discopodinolides B and C exhibited moderate antibacterial activities against the pathogenic strains of E. coli, B. subtilis, and B. megaterium.

    Abstract Fungi are widespread in nature and have conquered nearly every ecological niche. Fungi occur not only in terrestrial but also in freshwater and marine environments. Moreover, fungi are known as a rich source of secondary metabolites. Despite these facts, the ecological role of many of these metabolites is still unknown and the chemical ecology of fungi has not been investigated systematically so far. This review intends to present examples of the various chemical interactions of fungi with other fungi, plants, bacteria and animals and to give an overview of the current knowledge of fungal chemical ecology.

    Abstract Fruiting bodies of Laccaria proxima were screened for the presence of new secondary metabolites by means of HPLC-UV and LC-HR-(+)-ESIMS. Thus, two isomeric alkaloids with a highly unusual core structure, E-proxamidine and its Z-isomer, were isolated from Laccaria proxima. The proxamidines consist of an eight-membered heterocyclic ring system with a formamidine unit. The structures were established by 2D NMR spectroscopic methods, HR-(+)-ESIMS, and HR-(+)-ESIMS/MS. The proxamidines are probably biosynthetically derived from tryptophan, dimethylallyl pyrophosphate, and S-adenosylmethionine and the eight-membered ring of the proxamidines is likely to be generated by a rearrangement of the tryptophan sceleton. Metabolic profiling of fruiting bodies of some other Laccaria species revealed that the proxamidines appear in significant amounts only in L. proxima making the compounds suitable as chemotaxonomic markers. E-Proxamidine exhibits herbicidal activity against Lepidium sativum.
