Paeoniflorigenone
Paeoniflorigenone is a depolarizing neuromuscular blocking agent, being similar to succinylcholine.Paeoniflorigenone is cytotoxic and induces apoptosis selectively in the cancer cell lines. Paeoniflorigenone shows anti-inflammatory effects, it may take part in improving blood circulation by inhibiting ether platelet aggregation and/or blood coagulation.

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.

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.

Platelet anti-aggregatory and blood anti-coagulant effects of compounds isolated from Paeonia lactiflora and Paeonia suffruticosa.[Pubmed:
20824965]
The roots of two Paeoniaceae family members have long been used as traditional medicines in Korea, China, and Japan. Dry roots of Paeonia lactiflora and dry root bark of P. suffruticosa are used under the traditional names of Paeoniae Radix and Moutan Cortex, respectively.
METHODS AND RESULTS:
Both Paeoniae Radix and Moutan Cortex have been used as remedies for cardiovascular diseases, for improving blood circulation, or for other uses. It was postulated that both plants may contain common active constituents that contribute to inhibiting blood coagulation and/or platelet aggregation. Eighteen compounds, which have been reported to be present in both plant medicines, were evaluated for their effects on platelet aggregation and blood coagulation.
CONCLUSIONS:
Paeonol (5), paeoniflorin (9), benzoylpaeoniflorin (11), and benzoyloxypaeoniflorin (12) were found to be the major common active constituents and they would collectively contribute to improving blood circulation through their inhibitory effects on both platelet aggregation and blood coagulation. In addition, methylgallate (4), (+)-catechin (7), Paeoniflorigenone (8), galloylpaeoniflorin (13), and daucosterol (16) may also take part in improving blood circulation by inhibiting ether platelet aggregation and/or blood coagulation.

Apoptosis-inducing activity and antiproliferative effect of Paeoniflorigenone from moutan cortex[Reference:
WebLink]
METHODS AND RESULTS:
Ninety samples from the extracts of plants from traditional Chinese medicines were screened for antitumor activity. Paeoniflorigenone (PFG) was isolated as an active ingredient from the root of moutan cortex, which showed the strongest activity. In addition, our data indicated that PFG was cytotoxic and induced apoptosis selectively in the cancer cell lines.
CONCLUSIONS:
These effects were cancelled by the addition of caspase inhibitor Z-VAD-FMK, suggesting that it was mediated by caspase-3 activation.

Anti-inflammatory effect of paeoniflorigenone isolated from Paeoniae Radix.[Reference:
WebLink]
In Northeast Asia, Paeoniae Radix has been used in treatments of inflammation-causing diseases such as arthritis for many centuries. Paeoniflorin, one of the principle bioactive monoterpene glucosides from the paeony root, is reported to be mostly responsible for the effectiveness of the treatments. However, the anti-inflammatory effect of a monoterpene, Paeoniflorigenone (PFG) which partially has the moiety of paeoniflorin minus a glucose structure is unknown.
Thus, the aim of this work was to investigate anti-inflammatory activity of PFG.
METHODS AND RESULTS:
For the investigation, PFG activity on the NO (nitric oxide) prodn. from LPS-stimulated macrophages, and the anti-inflammatory effect was tested in the animal model of septic arthritis caused by Candida albicans, a major etiol. agent for septic arthritis. For induction of the arthritis, mice were administered with an emulsion of C. albicans cell wall (CACW) mixed with Complete Freund's Adjuvant (CFA) via footpad-injection (Day 0); PFG at a dose of 0.5 or 1 mg/mouse (25 or 50 mg/kg of body-wt.) was given to the animals on Day 3, 6, and 9; footpads were scored for arthritis. Moreover, the PFG effect on proliferation of T-lymphocyte that causes aggravation of arthritis was addnl. tested.

Blocking effects of a new component, paeoniflorigenone, in paeony root on neuromuscular junctions of frogs and mice.[Pubmed:
6471620]
METHODS AND RESULTS:
A new monoterpene, Paeoniflorigenone (PFG) (100-900 micrograms/ml), which was isolated from paeony roots and identified chemically, suppressed both indirectly and directly stimulated muscle twitchings of frog sciatic nerve-sartorius muscle preparation, and it indirectly stimulated muscle twitchings of phrenic nerve-diaphragm muscle preparations. The suppression effect by PFG (300 micrograms/ml) on twitching was not reversed by neostigmine (60 micrograms/ml) and was restored by washing out of PFG. PFG (150 micrograms/ml) depolarized the diaphragm muscle membranes by 10 mV and did not change the electrotonic potentials. PFG (100 micrograms/ml) inhibited weakly acetylcholine (5 micrograms/ml)-induced slow contractions.
CONCLUSIONS:
These results demonstrated that PFG is a depolarizing neuromuscular blocking agent, being similar to succinylcholine, except that PFG did not produce any contraction, but succinylcholine did.
