Flavonoids from Praxelis clematidea R.M. King and Robinson modulate bacterial drug resistance.[Pubmed: 21666549]

METHODS AND RESULTS:
Chemical studies of Praxelis clematidea R.M. King & Robinson resulted in the isolation of six flavones: Apigenine, genkwanine, 7,4'-dimethylapigenin, trimethylapigenin, cirsimaritin and tetramethylscutellarein, which were tested for their toxicity against Staphylococcus aureus SA-1199B, a strain possessing the NorA efflux pump. Efflux pumps are integral proteins of the bacterial membrane and are recognized as one of the main causes of bacterial drug resistance, since they expel antibiotics from the cell. The inhibition of this transporter is one form of modulating bacterial resistance to antimicrobial drugs. The flavones tested did not show any significant antibacterial activity against the Staphylococcus aureus strain used, but were able to modulate bacterial drug resistance.
CONCLUSIONS:
This property might be related to the degree of lipophilicity of the flavones conferred by the methoxyl groups, since 4',5,6,7-Tetramethoxyflavone the most methoxylated compound, reduced the minimal inhibitory concentration of the drug 16-fold.

Effect of Eupatorium odoratum on blood coagulation.[Pubmed: 1783877]

METHODS AND RESULTS:
The purified compound, 4',5,6,7-Tetramethoxyflavone, is an active ingredient isolated from Eupatorium odoratum, a Thai indigenous plant that has long been used to stop bleeding. This compound was studied in vitro for the effect on blood clotting factor activities. It was found that the compound enhanced blood coagulation, the observed APTT being shorter than that observed in the control.
CONCLUSIONS:
The result suggested that the compound accelerated clotting time through the intrinsic pathway of the coagulation which may involve the reaction of factor XII, factor XI, factor IX or factor VIII.

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.
