存储与注意事项

1. 在您收到产品后请检查产品。如无问题，请将产品存入冰霜并且样品瓶保持密封，产品可以存放长达24个月（2-8摄氏度）。

2. 只要有可能，产品溶解后，您应该在同一天应用于您的实验。但是，如果您需要提前做预实验，或者需要全部溶解，我们建议您将溶液以等分试样的形式存放在-20℃的密封小瓶中。通常，这些可用于长达两周。使用前，打开样品瓶前，我们建议您将产品平衡至室温至少1小时。

3. 需要更多关于溶解度，使用和处理的建议？请发送电子邮件至：service@chemfaces.com

Description:

Isoginkgetin is a MMP-9 inhibitor, also a pre-mRNA splicing inhibitor with IC 50 of 30 uM. Isoginkgetin can up-regulate adiponectin secretion with potency comparable to that of rosiglitazone, a known modulator of adiponectin production. Isoginkgetin has anti-tumor activity, it can inhibit tumor cell invasion by regulating phosphatidylinositol 3-kinase/Akt-dependent matrix metalloproteinase-9 expression.

Targets:

MMP(e.g.TIMP) | PI3K | Akt | NF-kB | AMPK | SOD

In vitro:

J Biol Chem. 2008 Nov 28;283(48):33147-54.

The biflavonoid isoginkgetin is a general inhibitor of Pre-mRNA splicing.[Pubmed: 18826947]

Membrane-permeable compounds that reversibly inhibit a particular step in gene expression are highly useful tools for cell biological and biochemical/structural studies. In comparison with other gene expression steps where multiple small molecule effectors are available, very few compounds have been described that act as general inhibitors of pre-mRNA splicing.
METHODS AND RESULTS:
Here we report construction and validation of a set of mammalian cell lines suitable for the identification of small molecule inhibitors of pre-mRNA splicing. Using these cell lines, we identified the natural product isoginkgetin as a general inhibitor of both the major and minor spliceosomes. Isoginkgetin inhibits splicing both in vivo and in vitro at similar micromolar concentrations. It appears to do so by preventing stable recruitment of the U4/U5/U6 tri-small nuclear ribonucleoprotein, resulting in accumulation of the prespliceosomal A complex. Like two other recently reported general pre-mRNA splicing inhibitors, isoginkgetin has been previously described as an anti-tumor agent.
CONCLUSIONS:
Our results suggest that splicing inhibition is the mechanistic basis of the anti-tumor activity of isoginkgetin. Thus, pre-mRNA splicing inhibitors may represent a novel avenue for development of new anti-cancer agents.

Effect of Isoginkgetin on Scavenge of Oxygen Free Radical in Anoxic Rats.[Reference: WebLink]

METHODS AND RESULTS:
Chemiluminescence method and modified nitrous acid method were applied to determine the concentration of superoxide anion radical in plasma and erythrocyte of rats and the activity of superoxide dismutase(SOD) respectively. The results showed that Isoginkgetin (0.3mg/kg ip for 3d) could reduce the level of O2·- in plasma and erythroeyte (p<0.01) and sometimes increase the activity of SOD in anoxic rats, the action being stronger than aspirin.
