Article

Based on a reaction of ninhydrin with phenols, a new embelin-ninhydrin adduct has been synthesized and characterized. The adduct exhibits high antioxidant activity in the DPPH test. The analgesic and anti-inflammatory activity was also found to be better than that of the parent compound (embelin). In the acetic-acid-induced writhing test, almost complete abolition of writhing was observed at 10 and 20 mg/(kg body weight) doses of embelin-ninhydrin adduct and the results were better than those achieved with the standard drug pentazocine.

Keywords
