Cumarinas

(+)-6-(2-Hydroxy-3-methoxy-3-methylbutyl is a structural isomer of Ent-toddalolactone, which belongs to the coumarin group.

3-Aminocoumarin (3-aminochromen-2-one) is the key intermediate for the metal complexes.

7-BFC (7-Benzyloxy-4-(trifluoromethyl)coumarin) is a coumarin-like fluorescent substrate that is a cytochrome marker for the study of CYP subtypes.

Umbelliferone (UMB), a natural antioxidant, is benzopyrone in nature, and it is present in the fruits of golden apple and bitter orange, UMB has a protective effect on membrane fatty acid composition of liver and kidney as supported by antioxidant and antihyperlipidemic effects of UMB reported earlier as evidenced by improved histopathological changes, hepatic and nephritic markers, indicating recovery from the risk of diabetic complications; UMB has antihyperglycemic effect, UMB at 30 mg/kg of body weight possesses a promising antihyperglycemic effect that is comparable with glibenclamide.[1,2]

Sphondin, a furanocoumarin derivative isolated from Heracleum laciniatum, possesses an inhibitory effect on IL-1beta-induced increase in the level of COX-2 protein and PGE(2) release in A549 cells, the inhibitory mechanism, at least in part, through suppression of NF-kappaB activity, suggests that sphondin may have the therapeutic potential as an anti-inflammatory drug on airway inflammation.
