Lignans

Benzylbenzofuran derivative-1 (Compound 8), a benzylbenzofuran derivative, can be isolated from Silene conoidea.

Piperulin A is a potent inhibitor of PAFR. Piperulin A inhibits the specific binding of PAFR on isolated rabbit platelet plasma membranes with an IC₅₀ of 7.3 μM.

Aschantin, a bisepoxylignan, can be isolated from Magnolia biondii. Aschantin has antiplasmodial, Ca²⁺-antagonistic, platelet activating factor-antagonistic, and chemopreventive activities. Aschantin is a mTOR kinase inhibitor. Aschantin is also an inhibitor of Cytochrome P450 and UGT enzyme.

6′-Hydroxyjusticidin C is a lignan, that can be isolated from Justicia procumbens.

Dihydrodehydrodiconiferyl alcohol 9-O-β-D-xylopyranoside is an anti-hepatitis B virus (anti-HBV) agent. Dihydrodehydrodiconiferyl alcohol 9-O-β-D-xylopyranoside inhibits HBV surface antigen (HBsAg) and HBV e antigen (HBeAg) secretion on Hep G2.2.15 cell line, with IC₅₀ values of 1.67 and >2.15 mM, respectively.

Acuminatin is a new bis-phenylpropide can be isolated from Magnolia acuminata L.

Picropodophyllol is a triol.

Matairesinol monoglucoside is a STING activator. Matairesinol monoglucoside modulates the STING-TBK1-IRF3 signaling axis, promotes STING transcriptional expression, increases TBK1 and IRF3 phosphorylation. Matairesinol monoglucoside induces IFN-α and IFN-β production, reduces HBV DNA, HBsAg, and HBeAg expression. Matairesinol monoglucoside can be used for the research of hepatitis b virus (hbv) infection.

(+)-Medioresinol Di-O-β-D-glucopyranoside is a lignan glucoside with strong inhibitory activity of 3', 5'-cyclic monophosphate (cyclic AMP) phosphodiesterase.

(-)-Lyoniresinol is a lignan isolated from the Tarenna attenuata with antioxidant activities. (-)-Lyoniresinol has radical scavenging activities against DPPH with an IC₅₀ of 82.4 μM.
