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.

Biological Activity of Pterolactam

In vitro

Heterocyclic compounds from Chrysanthemum coronarium L. and their inhibitory activity on hACAT-1, hACAT-2, and LDL-oxidation.[Pubmed: 18481011]

Arch Pharm Res. 2008 May;31(5):573-8.


METHODS AND RESULTS:
The aerial parts of Chrysanthemum coronarium L. were extracted with MeOH, and the concentrated extract was partitioned using EtOAc, n-BuOH, and H(2)O, successively. Repeated column chromatography of the EtOAc and n-BuOH fractions gave a new heterocycle, 5,5'-dibuthoxy-2,2'-bifuran (1) along with five known compounds: methyl trans-ferulate (2), prunasin (3), sambunigrin (4), Pterolactam (5), and adenosine (6), which were identified by several spectroscopic methods including NMR and MS.
CONCLUSIONS:
This paper is the first report on the isolation of these compounds from C. coronarium L. The IC(50) values of compound 1 for human Acyl-CoA:cholesterol acyltransferase (hACAT)-1 and hACAT-2 were 0.16 mM and 0.19 mM, respectively. Compound 2 inhibited low-density lipoprotein (LDL) oxidation with an IC(50) value of 7.7 microM.
