9,13β-Epidioxy-8(14)-abieten-18-oic acid has anti-inflammatory activities, it exhibits moderate activities on NO levels in LPS-stimulated murine microglia BV2 cells, with IC50 values of 57.3 ± 0.2 uM. It is also a potential antitumor-promoting diterpenoid, it shows potent inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol 13-acetate. 9 α ,13 β -Epidioxyabeit-8(14)en-18-oic acid may contribute to the growth inhibitory effect of the pine needles and may play an important role in the allelopathy of red pine.
1,7-Dihydroxy-2,3-dimethoxyxanthone may have medicinal applications in managing inflammation, asthma, and allergy; it non-competitively but reversibly antagonizes contractions induced by chemical inflammatory mediators in the guinea pig trachea.
Capillarisin is a novel blocker of STAT3 activation and thus may have a potential in negative regulation of growth, metastasis, and chemoresistance of tumor cells, it inhibits cancer cell growth of osteosarcoma cells by inducing apoptosis accompanied with
(+)-Hannokinol and MESO-hannokinol can significantly inhibit lipopolysaccharide-induced nitric oxide production in BV2 microglial cells at concentrations ranging from 1 microM to 100 microM.
Luvangetin may have anti-inflammatory activity, it can inhibit NO and PGE2 production in LPS-stimulated BV2 cells. Luvangetin shows significant protection against pylorus-ligated and aspirin-induced gastric ulcers in rats and cold restraint stress-induced
Preskimmianine is the biogenetic precursor of skimmianine.It can significantly inhibit nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated BV2 cells.
1β,6α-Dihydroxyeudesm-4(15)-ene (Voleneol,DE) can attenuate the lipopolysaccharide (LPS)-induced inflammation in BV2 microglial cells, it also can dose-dependently suppress the protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenas
Cudratricusxanthone A has potent anti-proliferative, antioxidative, and monoamine oxidase inhibitory effects, it also possesses anti-cancer activities and provide a basis for developing effective therapeutic agents to inhibit growth and metastasis of brea
