Article Abstract

Three new lanostane triterpenoids () along with two new amides fatty compounds () were isolated from the ethyl acetate extract of a culture of the endophytic fungus gx-2. Their structures were identified by 1D and 2D NMR spectral data and HRESIMS. Compounds were evaluated for their anti-inflammatory and tyrosinase inhibition activities. The isolated compounds did not show inhibitory activities at a concentration of 100 μM against tyrosinase, while under the concentration of 10 μM, the release of lactate dehydrogenase (LDH) inhibition rate of compound was 54.45%, indicating that compound had moderate anti-inflammatory activity on the activation of NLRP3 inflammasome.

Five new non-holostane di- and trisulfated triterpene pentaosides, conicospermiumosides A-1 (), A-2 (), A-3 (), A-1 (), and A-2 () were isolated from the Far Eastern sea cucumber Levin et Stepanov (Cucumariidae, Dendrochirotida). Twelve known glycosides found earlier in other species were also obtained and identified. The structures of new compounds were established on the basis of extensive analysis of the 1D and 2D NMR spectra, as well as by the HR-ESI-MS data.

Article Synopsis
  • Researchers identified three important enzymes (AcCYP4, AcSDR6, AcSMT1) that play a role in the biosynthesis of lanostane-type triterpenoids in Antrodia camphorata.
  • The catalytic mechanisms of AcSDR6 were analyzed using crystal structure analysis to understand how it works.
  • These enzymes can potentially be used to synthesize at least 11 major types of Antrodia lanostanoids.

Chemical investigation on the rice fermentation of the fungus Physisporinus vitreus led to the isolation of ten previously undescribed lanostane triterpenoids, physivitrins I-R, and three known analogues. The new structures were elucidated on the basis of extensive spectroscopic methods, including 1D & 2D NMR, HRESIMS, UV and ECD. Physivitrins I and P exhibited significant inhibitory activities against NO production in LPS-activated RAW267.

Three previously undescribed highly modified lanostane triterpenoids, ganopyrone A, ganocolossusin I, and ganodermalactone Y, were isolated from the artificially cultivated fruiting bodies of the basidiomycete Ganoderma colossus TBRC-BCC 17711. Ganopyrone A possesses an unprecedented polycyclic carbon skeleton with an α-pyrone ring and C-18/C-23 bond. It showed antimalarial activity against Plasmodium falciparum K1 (multidrug-resistant strain) with an IC value of 7.

Double-strand RNA(dsRNA), which can induce inflammation, can be generated by necrotic keratinocytes in the skin environment. As an analog of dsRNA, polyinosinic-polycytidylic acid (poly(I:C)) is used to induce inflammation via the Toll-like Receptor 3 (TLR3) signaling pathway. Inotodiol, isolated from Inonotus obliquus, known as Chaga mushroom, is a natural lanostane-type triterpenoid with significant pharmacological activity and notable anti-inflammatory effects.
