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 Latifoline

In vitro

Structural influences on pyrrolizidine alkaloid-induced cytopathology.[Pubmed: 8378933]

Toxicol Appl Pharmacol. 1993 Sep;122(1):61-9.

Pyrrolizidine alkaloids (PAs), which are common constituents of hundreds of plant species around the world, have been reported to have cytotoxic, carcinogenic, antineoplastic, and genotoxic activity in vivo and in vitro. The exact mechanism of these biological toxicities is not yet clear.
METHODS AND RESULTS:
The ability of eight PA congeners to inhibit mitosis and induce megalocyte formation in cultured bovine kidney epithelial cells was studied to examine possible structural influences on these endpoints. Representatives of the three PA structural groups, the macrocycles (seneciphylline, senecionine, riddelliine, retrorsine, monocrotaline), open diesters (heliosupine, Latifoline), and a necine base (retronecine), were cocultured for 2 hr with a NADPH-generating system and rat liver S9. Macrocyclic PAs with alpha,beta-unsaturation (seneciphylline, senecionine, riddelliine, retrorsine) showed a dose-dependent inhibition of colony formation at 50, 100, and 300 microM and induction of megalocytosis at 500 microM. Colony growth resumed 3 weeks after removal of PAs at 50 and 100 microM, and normal cellular morphology returned 5 or 6 weeks after removal of PAs at 500 microM. The saturated macrocyclic (monocrotaline) and open diesters (heliosupine, Latifoline), elicited only a slight inhibition of colony formation and had no effect on cellular morphology at 500 microM. The necine base (retronecine) had no effect on either colony formation or cell morphology. Pyrrolic PAs (dehydrosenecionine, dehydromonocrotaline, dehydroretronecine) were more active in inhibition of colony formation than their parent compounds and were potent inducers of abnormal cellular morphology at 500 microM. An N-oxide metabolite, indicine N-oxide, was completely inactive.
CONCLUSIONS:
The results support previous studies showing that there are structural influences on PA-induced cytopathological effects.

Reactive enols in synthesis 2. Synthesis of (+)-latifolic acid and (+)-latifoline.[Pubmed: 11597224]


METHODS AND RESULTS:
We describe a short, enantioselective synthesis of the naturally occurring pyrrolizidine alkaloid (+)-Latifoline (1) employing a tandem [3,3] sigmatropic rearrangement/[1,2] allyl shift as a key step in constructing (+)-latifolic acid (4).
