Biological Activity
Description: Palbinone can induce HO-1 expression in the hepatic cells. It shows a strong inhibitory activity on the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH)-linked 3 alpha-hydroxysteroid dehydrogenase (3 alpha-HSD) of rat liver cytosol.
Targets: HO-1 | Nrf2 | PI3K | Akt | ERK | NADPH-oxidase
Palbinone Description
Source: The roots of Paeonia lactiflora Pall.
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.

Palbinone from Paeonia suffruticosa protects hepatic cells via up-regulation of heme oxygenase-1.[Pubmed: 23595773]
Paeonia suffruticosa has been traditionally employed for vitalizing blood circulation and alleviating liver and inflammatory diseases.
METHODS AND RESULTS:
The pathways by which Palbinone (PB) isolated from P. suffruticosa mediates heme oxygenase-1 (HO-1) induction were investigated using the specific inhibitors for PI3K and mitogen activated protein kinases pathways. The effect of Palbinone -treatment on Nrf2 translocalization and HO-1-antioxidant response element (ARE) regulation was examined employing Western blot and luciferase assays. Palbinone induced HO-1 expression via the activation of Nrf2 in the hepatic cells, and ARE-dependent genes were stimulated via the Palbinone -mediated Nrf2 activation. Palbinone -mediated HO-1 expression could be involved with PI3K/Akt and ERK1/2 pathways.
CONCLUSIONS:
Our study suggests the mechanism by which Palbinone induces HO-1 expression in the hepatic cells. This might substantiate the traditional applications of P. suffruticosa for the treatment of oxidative stress-related diseases including oxidant and inflammatory-mediated vascular and liver diseases.

Palbinone, a novel terpenoid from Paeonia albiflora; potent inhibitory activity on 3 alpha-hydroxysteroid dehydrogenase.[Pubmed: 8477499]

METHODS AND RESULTS:
Palbinone, a novel terpenoid isolated from the roots of Paeonia albiflora, showed a strong inhibitory activity on the reduced form of nicotinamide adenine dinucleotide phosphate (NADPH)-linked 3 alpha-hydroxysteroid dehydrogenase (3 alpha-HSD) of rat liver cytosol.
CONCLUSIONS:
The structures of Palbinone and a known compound, paeonilactone-B isolated from the active fraction of this plant were determined by the use of 2D NMR techniques (1H-1H COSY, 1H-13C COSY, 1H-13C long-range COSY, and HMBC).
