Biological Activity
Description: Heliangin shows anti-inflammatory effects, it can inhibit lipopolysaccharide-induced inflammation through signaling NF-κB pathway on LPS-induced RAW 264.7 cells. Heliangin has anti-cancer activity, it exhibits cytotoxicity against human oral epidermoid (KB), cervical epitheloid (Hela), and liver (hepa59T/VGH) carcinoma cells.
Targets: MAPK | NF-kB | TNF-α | IL Receptor | PGE
In vivo:
Biomed Pharmacother. 2017 Apr;88:102-8.
Heliangin inhibited lipopolysaccharide-induced inflammation through signaling NF-κB pathway on LPS-induced RAW 264.7 cells.[Pubmed: 28095354 ]
The Heliangin is a natural agent mainly isolated from Helianthus tuberosus L. (Asteraceae). In order to investigate the anti-inflammatory effect of Heliangin, several typical models in vivo and in vitro were performed.
METHODS AND RESULTS:
The RAW264.7 mouse macrophages cells were employed in vitro and dexamethasone were conducted as positive. The cytotoxicity results of Heliangin on RAW 264.7 cells provided the safety in vitro for further study.Moreover, we founded that MAPK and NF-κB signaling pathway play important roles in Heliangin's activity on RAW264.7 cells. Secondly, the acute toxic study results of Heliangin manifested the safety in vivo. Heliangin exerted anti-inflammation effect in a xylene-induced ear swelling in BALB/C mice and carrageenan-induced paw edema model in SD rats. The cytokines levels (TNF-α, IL-6 and PGE2) were decreased.
CONCLUSIONS:
The paw tissue immunochemistry assay demonstrated the IL-6 protein level changes in carrageenan-induced paw edema model under Heliangin administration.
Heliangin Description
Source: The herbs of Helianthus tuberosus L.
Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
Storage: 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.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Cytotoxic sesquiterpene lactones from Eupatorium kiirunense, a coastal plant of Taiwan.[Pubmed: 15921421 ]

METHODS AND RESULTS:
Phytochemical investigation of Eupatorium kiirunense has resulted in the isolation of eight new sesquiterpene lactones, constituted by five germacranolides, eupakirunsins A-E (1-5), and three heliangolides, eupaheliangolide A (6), 15-acetoxyHeliangin (7), and 3-epi-Heliangin (8), in addition to the known Heliangin (9) and 8,10-epoxy-9-acetoxythymol angelate (10). The structures of the new compounds were established through detailed analysis of their spectroscopic data.
CONCLUSIONS:
Compounds 6, 8, and 9 exhibited cytotoxicity against human oral epidermoid (KB), cervical epitheloid (Hela), and liver (hepa59T/VGH) carcinoma cells.
