Eighteen nitrogen-containing compounds (-) were isolated from cultures of the lichen-associated collected from the Qinghai-Tibet Plateau, including seven phenazine derivatives with three new ones, named subphenazines A-C (-), two new furan pyrrolidones (-), and nine known alkaloids. The structures were elucidated by spectroscopic data analysis, and absolute configurations were determined by single-crystal X-ray diffraction and ECD calculations. The phenazine-type derivatives, in particular compound , exhibited significantly better antineuroinflammatory activity than other isolated compounds (-).

Article Synopsis
  • Chinese medicinal fungi known as "Sanghuang" have a long history of recognized medicinal properties, but similar-looking fungi have often been mistakenly used in traditional medicine.
  • A study highlights the limitations of previous taxonomic methods for differentiating true Sanghuang fungi from Sanghuang-like fungi in the genera Porodaedalea, Phellinus, and Inonotus.
  • Utilizing mitogenomes, the research demonstrates distinct genetic characteristics that help classify these fungi more accurately, supporting the reclassification of Phellinus gilvus S12 as Sanghuangporus vaninii and providing tools for further research on these species.
