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.

Cytotoxic alkaloids from stems, leaves and twigs of Dasymaschalon blumei.[Pubmed: 21641972]


METHODS AND RESULTS:
Bioassay-guided fractionation of the cytotoxic ethyl acetate extract from the stems of Dasymaschalon blumei (Annonaceae) led to the isolation of four aristololactam alkaloids, including the hitherto unknown 3,5-dihydroxy-2,4-dimethoxyaristolactam (1), as well as the three known compounds, aristolactam BI, goniopedaline, and Griffithinam. Additionally, the cytotoxic extract from the combined leaves and twigs of the same plant yielded three known oxoaporphine alkaloids, oxodiscoguattine, dicentrinone, and duguevalline. The structures of aristolactams and oxoaporphine alkaloids were elucidated on the basis of spectroscopic methods. All isolates were evaluated for cytotoxicity against a panel of mammalian cancer cell lines and a noncancerous human embryonic kidney cell Hek 293.

Alkaloids from the roots of goniothalamus griffithii.[Pubmed: 10425141]


METHODS AND RESULTS:
Three new alkaloids-griffithazanone A (1), griffithdione (2), and Griffithinam (3)-were isolated from the roots of Goniothalamus griffithii, along with six known compounds, 4-methyl-2,9, 10-(2H)-1-azaanthracenetrione (4), velutinam, aristololactam BI, aristololactam BII, aristololactam AII, and norcepharanone B. Their structures were elucidated on the basis of spectral and chemical methods.
CONCLUSIONS:
The absolute configuration of griffithazanone A (1) was determined by the preparation of Mosher's esters.
