7-Isopentenyloxy-gamma-fagarine
7-Isopentenyloxy-gamma-fagarine has highly cytotoxicity against the MCF-7and Jurkat cell line. It has been used as a precursor for the chemical asymmetric synthesis of the enantiopure alkaloids: evoxine, anhydroevoxine and evodine.

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
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.

Cytotoxic activity and cell cycle analysis of quinoline alkaloids isolated from Haplophyllum canaliculatum Boiss.[Pubmed:
19551611 ]
METHODS AND RESULTS:
Bioassay-guided fractionation of Haplophyllum canaliculatum Boiss. (Rutaceae) extract resulted in isolation of five quinoline alkaloids: 7-Isopentenyloxy-gamma-fagarine, atanine, skimmianine, flindersine and perfamine. This is the first isolation of these compounds from this endemic species. The antitumor activity of these five isolates was evaluated against RAJI, Jurkat, KG-1a, HEP-2, MCF-7, HL-60 and HL-60/MX1 tumor cell lines. The highest cytotoxic effect was observed on acute lymphoblastic leukemia cell lines.
CONCLUSIONS:
7-Isopentenyloxy-gamma-fagarine, atanine, skimmianine and flindersine exhibited very high cytotoxicity against the RAJI cell line with IC(50) values of 1.5, 14.5, 15.6 and 14.9 microg/mL, respectively and 7-Isopentenyloxy-gamma-fagarine, atanine and skimmianine exhibited very high cytotoxicity against the Jurkat cell line with IC(50) values of 3.6, 9.3 and 11.5 microg/mL, respectively. 7-Isopentenyloxy-gamma-fagarine was also highly cytotoxic against the MCF-7 cell line (IC(50) = 15.5 microg/mL.

Synthesis, structure and stereochemistry of quinoline alkaloids from Choisya ternata.[Pubmed:
17728865]
METHODS AND RESULTS:
A range of seventeen quinoline alkaloids, involving several types of oxidations during their biosynthetic pathways, have been isolated from leaves of Choisya ternata. In addition to the nine known quinoline alkaloids, eight new members of the furoquinoline family, derived mainly from prenylation at C-5 (including two novel hydroperoxides), have been identified. The absolute configurations and enantiopurity values of all chiral quinoline alkaloids have been determined.
CONCLUSIONS:
One of the isolated alkaloids, 7-Isopentenyloxy-gamma-fagarine, has been used as a precursor for the chemical asymmetric synthesis of the enantiopure alkaloids: evoxine, anhydroevoxine and evodine. The possible roles of oxygenase and other oxygen-atom-transfer enzymes, in the biosynthetic pathways of the C. ternata alkaloids, have been discussed.
