1-Methyl-2-nonylquinolin-4(1H)-one has anti-inflammatory activity, it exhibits inhibitory activity on leukotriene biosynthesis in a bioassay using human polymorphonuclear granulocytes, with IC50 values of 12.1 microM.
Stilbostemin A, stilbostemin B , stilbostemin D , stilbostemin F , and stilbostemin G show structure-dependent inhibition of leukotriene biosynthesis with IC(50) values ranging from 3.7 to >50 microM.
(Z)-1-Methyl-2-(undec-6-enyl)quinolin-4(1H)-one shows strong inhibitory activity on leukotriene biosynthesis in human polymorphonuclear granulocytes, and it is very effective against mycobacteria.
9,11-Dehydro-β-boswellic acid is a compound with urease inhibitory activity and acts as an inhibitor of 5-lipoxygenase (5-LO), a critical enzyme in leukotriene biosynthesis.
