Figure 5From: Inhibition of hematopoietic prostaglandin D2 Synthase (H-PGDS) by an alkaloid extract from Combretum molle Secondary plot to determine K i for the alkaloids. Based on the type of inhibition, a re-plot of 1/Vmax versus [I] was used to determine Ki GSH values of alkaloids, since an uncompetitive type inhibition for GST Sigma with respect to GSH was obtained.Back to article page
