A characteristic feature of aggressive malignancy is the overexpression of lactic acid dehydrogenase- (LDH-) A, concomitant to pericellular accumulation of lactate. In a recent high-throughput screening, we identified Rhus chinensis (Mill.) gallnut (RCG) (also known as Galla Chinensis) extract as a
Enzyme preparations from leaves of Rhus typhina L. (sumach) catalyzed the galloylation of 1,2,3,4,6-penta-O-galloyl-beta-D-glucopyranose in the presence of the acyl donor beta-glucogallin (1-O-galloyl-beta-D-glucopyranose), yielding a variety of oligomeric gallotannins (hexa- to nonagalloylglucoses)
The inhibitory effects of pure galloylglucose (1,2,3,4,6-penta-O-galloyl-beta-D-glucose) on the respiratory chain of rat liver mitochondria were investigated. The respiratory control ratio (RCR) decreased by 50% on addition of 20 microM pentagalloylglucose to highly coupled mitochondria, but the
