Natural COX-2 inhibition

 Curcuma zedoaria, Eugenia caryophyllata, Pterocarpus santalius, Rehmania glutinosa and Tribulus terrestris showed potent inhibition of COX-2 activity (>80% inhibition at the test concentration of 10 micro g/ml).

Abstract

The inhibitors of prostaglandin biosynthesis and nitric oxide production have been considered as potential anti-inflammatory and cancer chemopreventive agents. In this study, we evaluated approximately 170 methanol extracts of natural products including Korean herbal medicines for the inhibition of prostaglandin E(2) production (for COX-2 inhibitors) and nitric oxide formation (for iNOS inhibitors) in lipopolysaccharide (LPS)-induced mouse macrophages RAW264.7 cells. As a result, several extracts such as Aristolochia debilis, Cinnamomum cassia, Cinnamomum loureirii, Curcuma zedoaria, Eugenia caryophyllata, Pterocarpus santalius, Rehmania glutinosa and Tribulus terrestris showed potent inhibition of COX-2 activity (>80% inhibition at the test concentration of 10 micro g/ml). In addition, the extracts of A. debilis, Caesalpinia sappan, Curcuma longa, C. zedoaria, Daphne genkwa and Morus alba were also considered as potential inhibitors of iNOS activity (>70% inhibition at the test concentration of 10 micro g/ml). These active extracts mediating COX-2 and iNOS inhibitory activities are warranted for further elucidation of active principles for development of new cancer chemopreventive and/or anti-inflammatory agents.

Caesalpinia sappan is a species of flowering tree in the legume family, Fabaceae, that is native to Southeast Asia and the Malay archipelago. Common names include Sappanwood, Sapanwood, Patanga-Chekke Sappanga (Kannada), Pathimukham (Malayalam), and Suō (Japanese). Sappanwood belongs to the same genus as Brazilwood (C. echinata), and was originally called "brezel wood" in Europe.

This plant has many uses. It possesses medicinal abilities as an antibacterial and for its anticoagulant properties. It also produces a valued type of reddish dye called brazilin, used for dyeing fabric as well as making red paints and inks. Slivers of heartwood are used for making herbal drinking water in Kerala. Heartwood also contains juglone (5-hydroxy-1,4-naphthoquinone), also an active antimicrobial principle.[3] Homoisoflavonoids (sappanol, episappanol, 3'-deoxysappanol, 3'-O-methylsappanol, 3'-O-methylepisappanol[4] and sappanone A[5]) can also be found in C. sappan.
The wood is somewhat lighter in color than Brazilwood and its other allies, but the same tinctorial principle appears to be common to all. Sappanwood was a major trade good during the 17th century, when it was exported from Southeast Asian nations (especially Siam) aboard red seal ships to Japan.


 
As a footnote it is interesting to note that some references to this "plant" listed it as poisonous so one must consult a trained naturalist/botanist to ingest this and it will show up on toxicology screens.
