    Targets: Antifection
    Baicalin methyl ester Description
    Source: The roots of Scutellaria baicalensis Georgi
    Solvent: DMSO, Pyridine, Methanol, Ethanol, etc.
    Storage: 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

    After receiving: 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.

    Effects of Flavonoids and Alkaloids on Reverse Transcriptase[Reference: WebLink]
    One hundred-ninety flavonoids and 75 alkaloids were studied for their inhibitory effects on the Avian Myeloblastosis Virus reverse transcriptase (AMV-RT) by using (rA)_n-p(dT)_<12-18> or (rC)_n-p(dG)_<12-18> as a template-primer. Of the flavonoids tested, 6-hydroxyluteolin (50), pedalitin (52), 6-hydroxykaempferol (109) and quercetagetin (129), were the most potent inhibitors with IC_<50>≦10 μM. Five other flavonoids, baicalein (19), Baicalin methyl ester (23), scutellarein (33), myricetin (126) and gossypetin (130), gave IC_<50> between 35 and 200 μM. The kinetic studies on 50, 126 and 130 gave the inhibitory constants (K_i) of 10, 94 and 90 μM, respectively, with respect to the substrate and 5, 200 and 100 μM, respectively, with respect to the template-primer. Structurally different alkaloids such as isoquinoline, indol, steroidal, quinolizidine, pyrrolizidine, pyridine and imidazole alkaloids were also investigated for the activity and berberine type alkaloids were shown to have a strong inhibitory activity. Flavonoids or alkaloids that inhibited AMV-RT did not show any significant effect on DNA-polymerase I.

    Two flavone 2'-glucosides from Scutellaria baicalensis.[Pubmed: 7546551]
    Two new flavone glucosides, 5,2',6'-trihydroxy-6,7,8-trimethoxyflavone 2'-O-glucoside and 5,2',6'-trihydroxy-6,7-dimethoxyflavone 2'-O-glucoside were isolated from the aqueous methanol extract of the roots of Scutellaria baicalensis. From the extract, seven phenolics, 5,7,2',6'-terahydroxyflavone, 5,7,2',5'-tetrahydroxy-8,6'-dimethoxyflavone, skullcapflavone II, baicalin, Baicalin methyl ester, wogonin 7-glucuronide and 3,5,7,2',6'-pentahydroxyflavanone were also isolated.
