2-Hydroxy-3-(3-oxo-3-phenylpropyl)-4H-chromen-4-one, also known as flavokavain B, is a naturally occurring chemical compound belonging to the flavonoid class. It is found in the roots of the kava plant (Piper methysticum), which is native to the South Pacific and is traditionally used for its calming and mood-enhancing effects. 2-hydroxy-3-(3-oxo-3-phenylpropyl)-4H-chromen-4-one exhibits a unique structure, featuring a chromene ring with a hydroxyl group at position 2 and a 3-oxo-3-phenylpropyl side chain at position 3. Flavokavain B has been studied for its potential anti-inflammatory, antioxidant, and neuroprotective properties, making it a subject of interest in the field of natural product chemistry and pharmacology.

6431-16-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6431-16-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,3 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6431-16:
(6*6)+(5*4)+(4*3)+(3*1)+(2*1)+(1*6)=79
79 % 10 = 9
So 6431-16-9 is a valid CAS Registry Number.

Coumarin derivatives as protease inhibitors and antiviral agents

-

, (2008/06/13)

The present invention relates to novel coumarin derivatives and related compounds which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The coumarin derivatives are useful in the development of therapies for the treatment of viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized coumarins and of related structures.
