Influenza virus-IN-6 (Compound 35) serves as a potent inhibitor targeting the N-terminal domain of the polymerase acidic protein (PA N ) endonuclease subunit of the influenza virus, exhibiting an inhibitory concentration 50 (IC 50 ) value of 0.20 μM [1].

3,4'-Dihydroxyflavone (3,4'-DHF) is an oral active flavonoid. 3,4'-Dihydroxyflavone (3,4'-DHF) shows antiviral activity against Influenza A virus.

Germacrone, a major active component found in Curcuma zedoaria oil product, shows anti-inflammatory, antiandrogenic, and antivirus activities. It also inhibits the proliferation of glioma cells by promoting apoptosis.

8-Hydroxyapigenin (Isoscutellarein) is a brassinaceous compound derived from the plant Scutellaria baicalensis with anti-inflammatory, antioxidant and anti-influenza virus activity.

1, 2, 3, 4, 6-Pentagalloylglucose (Penta-O-galloyl-β-D-glucose) and gallic acid from Pistacia lentiscus have antimutagenic and antioxidant activities. 2. 1, 2, 3, 4, 6-Penta-O-galloyl-beta-D-glucose (PGG) possesses potent anti-proliferative and anti-invasive effects, it also has inhibition of inducible nitric oxide synthase and cyclooxygenase-2 activity. 3. PGG may serve as a model for the development of new types of anti-diabetic and anti-metabolic syndrome therapeutics. 4. 1, 2, 3, 4, 6-Penta- O -galloyl-β- d -glucose has vasodilatory and anti-inflammatory effects, it dilates vascular smooth muscle and suppresses the vascular inflammatory process via endothelium-dependent nitric oxide (NO)/cGMP signaling. 5. 1, 2, 3, 4, 6-Penta-O-galloyl-beta-D-glucose can decrease the level of extracellular hepatitis B virus (HBV) (IC5, 1. microg/ml) in a dose-dependent manner, it also can reduce the HBsAg level by 25% at a concentration of 4 microg/ml; the gallate structure of PGG may play a critical role in the inhibition of anti-HBV activity, suggests that PGG could be a candidate for developing an anti-HBV agent. 6. 1, 2, 3, 4, 6-Penta-O-galloyl-β-D-glucose has anti-parasitic activity, displays an EC5 value of 67 μM, at least 6.6-fold more effective than the standard drug benznidazole against trypomastigote forms of T. cruzi.
