Twelve drimane and coloratane sesquiterpenes, isolated from the stem bark of Ethiopian Warburgia ugandensis, were evaluated for inhibition of 12( S)-HETE using human platelets and of leukotriene B (4) formation using activated human neutrophile granulocytes. Among the compounds examined for
The dichloromethane extract of the stem bark of Warburgia ugandensis afforded three new coloratane sesquiterpenes, namely: 6alpha,9alpha-dihydroxy-4(13),7-coloratadien-11,12-dial (1), 4(13),7-coloratadien-12,11-olide (2), and 7beta-hydroxy-4(13),8-coloratadien-11,12-olide (3), together with nine
Methyl bromide (CH3Br) is a biocidal fumigant used widely in crop production and commodity preservation worldwide. CH3Br escapes to the stratosphere and releases bromine atom (Br), which contributes to significant destruction of the ozone (O3). It is therefore necessary to explore alternatives to
