Abstract Two new [named xylapyrrosides A (1) and B (2)] along with two known [pollenopyrrosides A (3) and B (=acortatarin A, 4)] naturally occurring spirocyclic pyrrole alkaloids were isolated and identified as minor components from the EtOH extract of the dried mycelia of the edible medicinal fungus Xylaria nigripes. Their structures were established by a combination of interpretation of spectroscopic data and single-crystal X-ray diffraction analyses. The isolates possess a unique tricyclic… Expand

Synthesis of the 2-formylpyrrole spiroketal pollenopyrroside A and structural elucidation of xylapyrroside A, shensongine A and capparisine B.
A convergent synthesis of the 2-formyl pyrrole spiroketal pollenopyrroside A is reported. The key step involves a Maillard-type condensation of an amine derived from deoxy-d-ribose with aExpand
Discovery, synthesis, biological evaluation and molecular docking study of (R)-5-methylmellein and its analogs as selective monoamine oxidase A inhibitors.
TLDR
(R)-5-Methylmellein (5-MM), the major ingredient in the fermented mycelia of the medicinal fungus Xylaria nigripes, was found to be a selective inhibitor against monoamine oxidase A (MAO-A) and might play an important role in the clinical usage of this edible fungus as an anti-depressive traditional Chinese medicine (TCM). Expand
Xylarinaps A-E, five pairs of naphthalenone derivatives with neuroprotective activities from Xylaria nigripes.
TLDR
Five pairs of undescribed naphthalenone derivative enantiomers, xylarinaps A-E, were isolated from the ethyl acetate extracts of the solid fermentation of Xylaria nigripes, which has been used as a traditional Chinese medicinal fungus for the treatment of insomnia, trauma, and depression. Expand
Taste-Active Maillard Reaction Products in Roasted Garlic (Allium sativum).
TLDR
The thermal generation of the literature known spiroalkaloids 1-4 is reported for the first time and revealed a bitter taste with thresholds between 0.5 and 785 μmol/kg for 1-5 and 6, thus giving evidence for its potential taste modulation activity in processed garlic preparations. Expand
Pyrrole Alkaloids from the Edible Mushroom Phlebopus portentosus with Their Bioactive Activities
TLDR
Seven pyrrole alkaloids, three of which are novel (phlebopines A–C (1–3)), were isolated from the fruiting bodies of the edible mushroom Phlebopus portentosus and displayed remarkable neuroprotective effects against hydrogen peroxide (H2O2)-induced neuronal-cell damage in human neuroblastoma SH-SY5Y cells. Expand
