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 Isoerysenegalensein E

Description1. Isoerysenegalensein E shows significant cytotoxicity against HL-60 cells, it induces apoptosis in HL-60 cells through activation of the caspase-9/caspase-3 pathway, which is triggered by mitochondrial dysfunction. 2. Isoerysenegalensein E shows anti-estrogenic activity comparable to that of 4-hydroxytamoxifen, a typical estrogen receptor antagonist.
TargetsCaspase | Estrogen receptor | Progestogen receptor

Three new isoflavonoids from Erythrina caffra.[Pubmed:25115087]

Nat Prod Commun. 2014 Jun;9(6):817-20.

Three new isoflavonoids, 5,7-dihydroxy-2',4'-dimethoxy-5'-(3-methylbut-2-enyl) isoflavanone (erycaffra A) (1), 5,7-dihydroxy-2',4'-dimethoxy-5'-(2-hydroxy-3-methylbut-3-enyl)isoflavanone (erycaffra B) (2), and 5,7-dihydroxy-6,8-di-(2-hydroxy-3-methylbut-3-enyl)isoflavone (erycaffra C) (3), were isolated from the stem bark of E. caffra Thunb., along with eight known compounds, namely, alpinumisoflavone (4), Isoerysenegalensein E (5), beta-amyrin (6), oleanolic acid (7), octacosyl-E-ferulate (8), triacontyl-4-hydroxycinnamate (9), n-tetracosyl p-coumarate (10) and octacosan-1-ol (11). The structures were determined on the basis of spectroscopic (1D, 2D-NMR) and MS data and by comparison with literature values.

Induction of apoptosis by isoflavonoids from the leaves of Millettia taiwaniana in human leukemia HL-60 cells.[Pubmed:16557456]

Planta Med. 2006 Apr;72(5):424-9.

We have isolated two new isoflavonoids, millewanin-F (1) and furowanin-A (2), together with five known isoflavonoids from the leaves of Millettia taiwaniana Hayata (Leguminosae) and examined their effects on the growth of human leukemia HL-60 cells. Among the isolated isoflavonoids, furowanin-A (2), warangalone (3), isoerysenegalensein-E (4), and euchrenone b10 (6) showed significant cytotoxicity against HL-60 cells. After treatment with three of the cytotoxic isoflavonoids, furowanin-A (2), warangalone (3), and isoerysenegalensein-E (4), fluorescence microscopy with Hoechst 33,342 staining revealed that the percentage of apoptotic cells with fragmented nuclei and condensed chromatin increased in a time-dependent manner. In addition, the activities of caspase-9 and caspase-3 were also enhanced in a time-dependent manner upon treatment with the isoflavonoids 2, 3, and 4. Caspase-9 and caspase-3 inhibitors suppressed apoptosis induced by isoflavonoids 2, 3, and 4. These results suggest that the isoflavonoids induced apoptosis in HL-60 cells through activation of the caspase-9/caspase-3 pathway, which is triggered by mitochondrial dysfunction.
