kadsurin

Kadsurin has anti-oxidant activity, it induces enzymes capable of scavenging oxygen radical species in the liver. Kadsurin may be valuable antitumor promoters or chemopreventors.

Kadsurin A Analogue-1 (Compound 8), a lignan, can be extracted from Piper argyrophylum [1].

Kadsurin A has anti-platelet activating factor activities.

Acetyl-binankadsurin A (compound 5), a lignan obtained from Kadsura longipedunculata, exhibits weak inhibitory effects on HIV-1 protease, demonstrating an IC50 value exceeding 100 μg mL [1].

Yunnankadsurin B, a dibenzocyclooctene-type lignan, is derived from the stems of Schisandra chinensis (Kadsura) [1].

Angeloylbinankadsurin A (compound 7), an anti-rheumatoid arthritis (RA) agent, can be extracted from the EtOAc and CH2Cl2 extracts of Black Tiger Beard. It displays inhibitory effects on RA-FLS cells with an IC50 of 11.70 μM and exhibits mild toxicity to human cancer cell lines Hela and BGC-823, with IC50 values of 19.9 μM and 21.93 μM, respectively [1].

Futokadsurin C can inhibit nitric oxide production by a murine macrophage-like cell line (RAW 264.7), which is activated by lipopolysaccharide and interferon-gamma.
