Chlomultiols A-L, sesquiterpenoids from Chloranthus multistachys and their anti-inflammatory activities.

Twelve undescribed sesquiterpenoids, named chlomultiols A-L, involving three lindenane sesquiterpenoid dimers, three eudesmane sesquiterpenoids, three guaiane sesquiterpenoids, and three cadinane sesquiterpenoids, along with four known compounds, were obtained from the whole plant of Chloranthus multistachys. Their structures were determined through spectroscopic techniques (HRESIMS, 1D and 2D NMR). In addition, the absolute and relative configurations of the undescribed compounds were established by using single crystal X-ray crystallography, NOESY and CD spectroscopy.

Three pairs of sesquiterpene enantiomers from pei.

Phytochemical investigation on the whole plant of pei (Chloranthaceae) afforded three pairs of new sesquiterpene enantiomers (+)/(-)-chlorantene M [(+)/(-)-], (+)/(-)-chlorantene M1 [(+)/(-)-] and (+)/(-)-chlorantene N [(+)/(-)-]. The structures of new compounds were determined through spectroscopic techniques (HR-ESI-MS, 1 D and 2 D NMR), besides, their absolute and relative configurations were established by using Single-crystal X-ray diffraction analysis and CD spectrum. The anti-inflammatory potential of all compounds was evaluated by applying LPS induced RAW 264.

An electrochemical Hg sensor based on signal amplification strategy of target recycling.

In this work, an unmodified homogeneous electrochemical sensor based on electrochemical bonding and catalytic hairpin assembly (CHA) was first constructed for the high sensitivity detection of Hg. Herein, tetraferrocene, a synthesized compound, was used as a signal marker that modified both ends of the hairpin probe to amplify the electrochemical signal. The interaction of T-Hg-T could induce the catalytic self-assembly of hairpins by means of auxiliary DNA.
