Abstact

Inhibiting PLA(2) activity should, in theory, be an effective approach to control the inflammation. Several naturally occurring polyphenolic compounds have been reported as inhibitors of PLA(2) . Among the naturally occurring polyphenols, catechol (1,2-dihydroxybenzene) possesses anti-inflammatory activity. Catechol can inhibit cyclooxygenase and lipo-oxygenase. By means of enzyme kinetic study, it was revealed that catechol can inhibit PLA(2) also. Crystal structure showed that catechol binds to PLA(2) at the opening of the active site cleft. This might stop the entry of substrate into the active site. Hence, catechol can be used as a lead compound for the development of novel anti-inflammatory drugs with PLA(2) as the target.
