Bioactivity-directed fractionation of the combined culture medium and mycelium extract of the endophytic fungus Xylaria feejeensis strain SM3e-1b, isolated from Sapium macrocarpum, led to the isolation of three known natural products: (4S,5S,6S)-4-hydroxy-3-methoxy-5-methyl-5,6-epoxycyclohex-2-enone or coriloxine, 1; 2-hydroxy-5-methoxy-3-methylcyclohexa-2,5-diene-1,4-dione, 2; and 2,6-dihydroxy-5-methoxy-3-methylcyclohexa-2,5-diene-1,4-dione or fumiquinone B, 3. This is the first report of compound 3 being isolated from this species. Additionally, four new derivatives of coriloxine were prepared: (4R,5S,6R)-6-chloro-4,5-dihydroxy-3-methoxy-5-methylcyclohex-2-enone, 4; 6-hydroxy-5-methyl-3-(methylamino)cyclohexa-2,5- diene-1,4-dione, 5; (4R,5R,6R)-4,5-dihydroxy-3-methoxy-5-methyl-6-(phenylamino)cyclohex-2-enone, 6; and 2-((4-butylphenyl)amino)-5-methoxy-3-methylcyclohexa-2,5-diene-1,4-dione, 7. X-ray analysis allowed us to unambiguously determine the structures and absolute configuration of semisynthetic derivatives 4, 5, and 6. The phytotoxic activity of the three isolated natural products and the coriloxine derivatives is reported. Germination of the seed, root growth, and oxygen uptake of the seedlings of Trifolium pratense, Medicago sativa, Panicum miliaceum, and Amaranthus hypochondriacus were significantly inhibited by all of the tested compounds. In general, they were more effective inhibiting root elongation than suppressing the germination and seedling oxygen uptake processes as shown by their IC50 values.

“…This especially concerns the strains used in the study on the molecular phylogeny of Xylaria by Lee et al (2000). The genotype most frequently referred to in the literature corresponds to a culture which was deposited by Chacko & Rogers (1981) and only tentatively referred to as X. hypoxylon by the authors. DNA sequences derived from this material were published by Spatafora & Blackwell (1993) and since then used as references (and representative of Xylariaceae and Xylariales) in numerous molecular phylogenetic studies.…”

“…Spatafora & Blackwell (1993) generated ribosomal DNA sequences of two representatives of Xylariaceae, Daldinia concentrica and Xylaria hypoxylon, in their early study on the molecular phylogeny of pyrenomycetes based on nrDNA sequence data. The sequence data derived from a "X. hypoxylon" strain, described first by Chacko & Rogers (1981) and deposited with ATCC were used in numerous phylogenetic studies as representative of Xylariales and Xylariaceae. We have only recently clarified that this fungus does not represent X. hypoxylon (see Peršoh et al 2008).…”

This paper constitutes a synopsis of our polythetic studies of the Xylariaceae, which was originally compiled in the course of a Habilitation thesis. Based on several thousands of specimens and several hundreds of cultures, morphological studies of the teleomorphs and anamorphs of these fungi were combined with chemotaxonomic studies based on HPLC-DAD/MS profiling, as well as PCR fingerprinting and molecular phylogenetic analyses. Numerous novel pigments and other natural products, many of which were shown to have biological activities were also isolated and identified, and their production in the course of the life cycle of their producer organisms was followed by HPLC profiling and biological assays. Numerous new species and even new genera were recognised in the course of this work. Finally, secondary metabolite production in cultures of Xylariaceae was correlated with molecular data and the production of certain chemotaxonomic marker compounds was found to be strongly correlated with a phylogeny based on ITS nrDNA, demonstrating that secondary metabolite profiles are not only important species-specific characters but even have phylogenetic significance. The work on Xylariaceae is proposed as a model how interdisciplinary, international collaborations can help to increase our understanding of the phylogenetic and evolutionary relationships, as well as the biology of fungal organisms. Similar work on other groups of the Ascomycota and Basidiomycota would certainly be rewarding.
