- Abstract
- Bioassay guided fractionation of extracts derived from submerged cultures of a Sanghuangporus sp. (i.e., the genus that was until recently referred to as the “Inonotus linteus complex” of medicinal mushrooms) originating from Kenya led to the isolation of a new spiro [furan-2,1’-indine]-3-one derivative, for which we propose the trivial name phelligridin L (1) together with the known compounds 3,14′-bihispidinyl (2), hispidin (3), ionylideneacetic acid (4), 1S-(2E)-5-[(1R)-2,2-dimethyl-6-methylidenecyclohexyl]-3-methylpent-2-enoic acid (5), phellidine E (6) and phellidine D (7). Compounds 1–3, showed moderate nematicidal activity against Caenorhabditis elegans with LD50 of 12.5 μg/m. The nematicidal activity of 3, 14′-bihispidinyl and hispidin (1, 2) has not been reported before. Furthermore, compounds 1–5 demonstrated moderate antimicrobial activity against various test organisms.
