Chicanine
Chicanine has anti-inflammatory activity in macrophages by down-regulating LPS-induced inflammatory cytokines in IκBα/MAPK/ERK signaling pathways. Chicanine also has good anti-proliferation (IC₅₀=44.2uM) on prostate cells and antioxidant activities (IC₅₀=26.0 uM,) with no significant toxic effects on normal cells.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Anti-inflammatory effects of chicanine on murine macrophage by down-regulating LPS-induced inflammatory cytokines in IκBα/MAPK/ERK signaling pathways[Pubmed:
24361309 ]
Schisandra chinensis Baill is a Chinese traditional medicine with multiple pharmacological activities.
METHODS AND RESULTS:
In this study, Chicanine, one of the major lignan compounds of S. chinesis, was investigated for suppressive effects on lipopolysaccharide (LPS)-induced inflammatory responses in murine macrophages (RAW 264.7 cells). Chicanine was found to have anti-inflammatory properties with the inhibition of nitric oxide (NO) and Prostaglandin E (2) (PGE2) production and nuclear factor-κB (NF-κB) signaling in LPS-stimulated RAW 264.7 cells with no cytotoxic effects. Treatment of RAW 264.7 cells with Chicanine down-regulated LPS-induced expression of pro-inflammatory cytokines including TNFα, IL-1β, MCP-1, G-CSF, cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS). These inhibitory effects were found with the blockage of p38 mitogen-activated protein kinase (MAPK), extracellular signal-regulated kinases 1 and 2 (ERK 1/2), and also IκB-α phosphorylation.
CONCLUSIONS:
These results indicated that anti-inflammatory actions of Chicanine in macrophages involved inhibition of LPS-induced TLR4-IκBα/MAPK/ERK signaling pathways.

Antioxidant and anti-proliferative activities of five compounds from Schisandra chinensis fruit.[Reference:
WebLink]
Schisandra chinensis fruit has been used as functional foods and traditional Chinese medicine for thousands years.
In order to illustrate the main active components, one triterpenoid and four lignan compounds were isolated from Schisandra chinensis.
METHODS AND RESULTS:
The antioxidant and anti-proliferative activities of the five compounds and extract were evaluated by DPPH radical-scavenging assay and MTT assay on prostate cancer cells PC3. The structures of the compounds were fully characterized, which were d-epigalbacin, machilin G, Chicanine, anwulignan, and epi-anwuweizic acid, respectively. Activity results showed that epi-anwuweizic acid had the highest cytotoxic activity on prostate cells (IC₅₀=36.5μM) but lower antioxidant activities. Chicanine had good anti-proliferation (IC₅₀=44.2μM) and antioxidant activities (IC₅₀=26.0μM,) with no significant toxic effects on normal cells.
CONCLUSIONS:
The results suggested that there were lignan and triterpenoid compounds in Schisandra chinensis to have biological activities on diseases associated with aging and cancer.

Chemical constituents of Osmanthus fragrans fruits.[Pubmed:
24791540]
By Silica gel, Sephadex LH-20 and other materials for isolation and purification and by physicochemical methods and spectral analysis for structural identification, 23 compounds were isolated and identified from ethyl acetate portion of alcohol extract solution of Osmanthus fragrans fruits.
METHODS AND RESULTS:
Their structures were identified as nicotinamide (1), D-allitol (2), 5-hydroxymethyl-2-furancarboxaldehyde (3), acetyloleanolic acid (4), benzoic acid (5), ergosta-7,22-dien-3-one (6), beta-sitosterol (7), borreriagenin (8), cerevistero (9), c-veratroylglycol (10), methyl-2-O-beta-glucopyranosylbenzoate (11), 3', 7-dihydroxy-4'-methoxyisoflavon (12), umbelliferone (13), caffeic acid methyl ester (14), oleanolic acid (15), (-) -Chicanine (16), dillapiol (17), 3beta,5alpha, 9alpha-trihydroxyergosta-7-22-dien-6-one (18), 2alpha-hydroxy-oleanolic acid (19), betulinic acid (20), betulin (21), 3, 3'-bisdemethylpinoresinol (22), and lupeol (23).
CONCLUSIONS:
All compounds were isolated from the osmanthus fruit for the first time. Except for compounds 4, 7, 15, 19, 23, the rest ones were isolated from the this plant for the first time.
