General tips：For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging：1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition：Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Pulsatilloside A and anemoside A3 protect PC12 cells from apoptosis induced by sodium cyanide and glucose deprivation.[Pubmed:12624827]

Planta Med. 2003 Feb;69(2):171-4.

Using sodium cyanide (NaCN) and glucose deprivation induced cell injury in PC12 as an injury model, we investigated the protective effects of pulsatilloside A and anemoside A 3 on neurons. The results showed that PC12 cells under the NaCN-injury and glucose deprivation would undergo apoptosis. Additions of pulsatilloside A and anemoside A 3, at dosages ranging from 0.1, 1 and 10 microg/ml, protected PC12 cells from apoptosis determined by MTT, LDH release analysis, and flow cytometry measurement.

Anemoside A3 Enhances Cognition through the Regulation of Synaptic Function and Neuroprotection.[Pubmed:25649278]

Neuropsychopharmacology. 2015 Jul;40(8):1877-87.

Compounds that have the ability to both strengthen synaptic function and facilitate neuroprotection are valuable cognitive enhancers that may improve health and quality of life, as well as retard age-related cognitive deterioration. Medicinal plants are an abundant source of potential cognitive enhancers. Here we report that Anemoside A3 (AA3) isolated from Pulsatilla chinensis modulates synaptic connectivity in circuits central to memory enhancement. AA3 specifically modulates the function of AMPA-type glutamate receptors (AMPARs) by increasing serine phosphorylation within the GluA1 subunit, which is a modification required for the trafficking of GluA1-containing AMPARs to synapses. Furthermore, AA3 administration activates several synaptic signaling molecules and increases protein expressions of the neurotrophin brain-derived neurotrophic factor and monoamine neurotransmitters in the mouse hippocampus. In addition to acting through AMPARs, AA3 also acts as a non-competitive NMDA receptor (NMDAR) modulator with a neuroprotective capacity against ischemic brain injury and overexcitation in rats. These findings collectively suggest that AA3 possesses a unique ability to modulate the functions of both AMPARs and NMDARs. Concordantly, behavioral studies indicate that AA3 not only facilitates hippocampal long-term potentiation but also enhances spatial reference memory formation in mice. These multifaceted roles suggest that AA3 is an attractive candidate for further development as a cognitive enhancer capable of alleviating memory dysfunctions associated with aging and neurodegenerative diseases.

Anemoside A3-induced relaxation in rat renal arteries: role of endothelium and Ca2+ channel inhibition.[Pubmed:20506075]

Planta Med. 2010 Nov;76(16):1814-9.

Anemoside A(3), a lupane-type triterpenoid saponin, exists in the roots of Pulsatilla chinensis, but its pharmacological properties are largely unknown. The present study aimed to investigate the mechanisms underlying anemoside A(3)-induced relaxation in rat renal arteries. Changes of isometric force were determined on arteries with a myograph. Anemoside A(3) caused concentration-dependent relaxation in precontracted aortas, mesenteric, left coronary, and renal arteries. Removal of endothelium or treatment with charybdotoxin plus apamin slightly but significantly attenuated the relaxation in renal arteries. TEA(+) inhibited the relaxation caused by anemoside A(3) in renal arteries with and without endothelium while glibenclamide, BaCl(2), or capsaicin had no effect on it. Anemoside A(3) produced less relaxation in rings contracted by 60 mM KCl compared with rings contracted by receptor-dependent constrictors. It further inhibited contractions induced by Ca(2+) influx through nifedipine-sensitive voltage-gated Ca(2+) channels, nifedipine-insensitive receptor-operated Ca(2+) channels, and by intracellular Ca(2+) release. Pretreatment with nifedipine attenuated anemoside A(3)-induced relaxation. Taken together, the present results indicate that anemoside A(3) produces relaxation in rat renal arteries through multiple mechanisms. The release of CTX/apamin-sensitive endothelium-derived hyperpolarizing factor, stimulation of TEA(+)-sensitive K(+) channel, and inhibition of Ca(2+) influx jointly contribute to the relaxation.
