MATERIALS AND METHODS
The effect of GTG in the production of leukotriene was determined by enzyme inhibition studies on 12- lipoxygenase. The assay was carried out by ferrous oxidation of xylenol orange (FOX assay) and was compared to a positive control nordihydroguaiaretic acid. The effect of GTG on the production of proinflammatory cytokines TNF-α and IL-1β in monocytes were studied. For this, the monocytes were pretreated with various concentrations of GTG and subsequently stimulated with lipopolysaccharide. The cytokines TNF-α and IL-1β produced were quantified by ELISA and the results were compared to positive controls Rolipram and Dexamethasone respectively. The gene expression studies were carried out using qRT-PCR. The IC50 values were calculated and evaluated statistically.
