چکیده

Thirteen undescribed 24-methylene lanostane triterpenoids, named polyporenic acids E-M and fomitosides L-O, as well seventeen known analogues, were isolated from the fruiting bodies of mushroom Fomitopsis betulina. Their structures determined using 1D, 2D NMR, IR, HRESIMS. Fomitoside L fomitoside N exhibited cytotoxicity against HL60 leukemia cells (IC50 = 15.8 23.7 ?M, respectively). Among compounds, notable cytotoxicities selectivity with respect to MRC-5 healthy noticed for dehydropachymic acid 10.9 SI 8.6), pachymic 11.0 9.8), 3-epi-dehydrotumulosic 19.9 5.8) 12?-hydroxy-3?-(3?-hydroxy-4?-methoxycarbonyl-3?-methylbutyryloxy)-24-methyllanosta-8,24 (31)-dien-26-oic 19.2 2.2).

Lanostane triterpenoids from the mushroom Naematoloma fasciculare.

In our continuing search for structurally interesting and bioactive metabolites from Korean wild mushrooms, bioassay-guided fractionation and a chemical investigation of the MeOH extracts of the fruiting bodies of the mushroom Naematoloma fasciculare resulted in the isolation of four new lanostane triterpenoids (1-4), together with 11 known compounds (5-15). The structures of 1-5 were determine...

Triterpene glycosides and glucosyl esters, and a triterpene from the leaves of Schefflera actinophylla.

From the EtOAc and 1-BuOH fractions, three new ursane-type and four new lupane-type triterpenes, along with nine known glycosides and glycosyl esters of lupane-type were isolated from the leaves of Schefflera actinophylla. All the isolated compounds were obtained for the first time from this plant. The structures of the new triterpenes were determined through a combination of spectroscopic and ...

Fomitopsis betulina (formerly Piptoporus betulinus): the Iceman’s polypore fungus with modern biotechnological potential

Higher Basidiomycota have been used in natural medicine throughout the world for centuries. One of such fungi is Fomitopsis betulina (formerly Piptoporus betulinus), which causes brown rot of birch wood. Annual white to brownish fruiting bodies of the species can be found on trees in the northern hemisphere but F. betulina can also be cultured as a mycelium and fruiting body. The fungus has a l...
