Pteryxin - A promising butyrylcholinesterase-inhibiting coumarin derivative from Mutellina purpurea[Pubmed: 28286309]
Abstract Pteryxin is a dihydropyranocoumarin derivative found in Apiaceae family. In this study, pteryxin, which was previously isolated from the fruits of Mutellina purpurea, was investigated for its inhibitory potential against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), which are the key enzymes in the pathology of Alzheimer's disease (AD). The compound was tested in vitro using ELISA microplate reader at 100 μg/ml and found to cause 9.30 ± 1.86% and 91.62 ± 1.53% inhibition against AChE and BChE, respectively. According to our results, pteryxin (IC50 = 12.96 ± 0.70 μg/ml) was found to be a more active inhibitor of BChE than galanthamine (IC50 = 22.16 ± 0.91 μg/ml; 81.93± 2.52% of inhibition at 100 μg/ml). Further study on pteryxin using molecular docking experiments revealed different possible binding modes with both polar and hydrophobic interactions inside the binding pocket of BChE. Top docking solution points out to the formation of two hydrogen bonds with the catalytic residues S198 and H438 of BChE as well as a strong π - π stacking with W231. Therefore, pteryxin as a natural coumarin seems to be a strong BChE inhibitor, which could be considered as a lead compound to develop novel BChE inhibitors for AD treatment. Keywords: Alzheimer's disease; Cholinesterase inhibition; Molecular docking; Pteryxin; Pyranocoumarin.

Pteryxin: a coumarin in Peucedanum japonicum Thunb leaves exerts antiobesity activity through modulation of adipogenic gene network[Pubmed: 24993752]
Abstract Objectives: Partially purified hexane phase (HP) of Peucedanum japonicum Thunb (PJT) was identified as an antiobesity candidate. However, the compound responsible for the antiobesity activity remained unknown. Thus, in this study we isolated the active compound, to determine the mechanisms related to antiobesity activity in vitro. Methods: The HP was fractionated, and the effect on the triacylglycerol (TG) content was evaluated in 3T3-L1 preadipocytes and HepG2 hepatocytes. On the basis of comprehensive spectroscopic analyses, the structure of the active compound was identified as pteryxin, a known compound in PJT. However, to our knowledge, its biological activities against obesity have not been reported previously. The dose-dependent effect on the TG content, and the gene expressions related to adipogenesis, fatty acid catabolism, energy expenditure, lipolysis, and lipogenesis due to pteryxin (10, 15, and 20 μg/mL) were examined in vitro. Results: Pteryxin dose dependently suppressed TG content in both 3T3-L1 adipocytes (by 52.7%, 53.8%, and 57.4%, respectively; P < 0.05) and HepG2 hepatocytes (by 25.2%, 34.1%, and 27.4%, respectively; P < 0.05). Sterol regulatory element-binding protein-1 (SREBP-1c), fatty acid synthase (FASN), and acetyl-coenzyme A carboxylase-1 (ACC1) were down-regulated in pteryxin-treated 3T3-L1 adipocytes (by 18%, 36.1%, and 38.2%, P < 0.05) and HepG2 hepatocytes (by 72.3%, 62.9%, and 38.8%, respectively; P < 0.05). The adipocyte size marker gene, paternally expressed gene1/mesoderm specific transcript (MEST) was down-regulated (by 42.8%; P < 0.05), and hormone-sensitive lipase, a lipid catabolizing gene was up-regulated (by 15.1%; P < 0.05) in pteryxin-treated adipocytes. The uncoupling protein 2 (by 77.5%; P < 0.05) and adiponectin (by 76.3%; P > 0.05) were up-regulated due to pteryxin. Conclusion: Our study demonstrated that pteryxin in PJT plays the key role in regulating the lipid metabolism-related gene network and improving energy production in vitro. Thus, the results suggest pteryxin as a new natural compound to be used as an antiobesity drug in the pharmaceutical industry. Keywords: 3T3-L1 adipocytes; HepG2 hepatocytes; Lipid metabolism; Obesity; Peucedanum japonicum Thunb; Pteryxin.

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.
