A series of coumarin derivatives were synthesized in two steps from phloroglucinol. The anti-inflammatory activities of these derivatives were evaluated by means of inhibiting NO production in LPS-induced RAW 264.7 cells. Derivatives 3, 8, 10, 11, and 13 exhibited low micromolar levels of anti-inflammatory activities, and these derivatives also protected DNA against hydroxyl radical attack. Coumarin derivative 8 was the most potent derivative among those tested herein against NO production in LPS-induced RAW 264.7 cells with an IC50 value of 7.6 μM, and it effectively reduced the hydroxyl radical production by 50% at 100 μM in the electron spin resonance study.

A chemotaxonomic survey for biologically active compounds from Malaysian Calophyllum species led to the finding of the four new benzoylcoumarins 1a, 2, 3, and 4a (including the unusual prenylated 6-benzoylcoumarin 1a, two uncommon coumarins 5 and 6a with
