IC50 value 0.9 microgramm per ml, Ki value 0.21 microgramm per ml 12736 1.1.1.100 1,2,3,4,6-penta-O-galloyl-beta-D-glucose minimal inhibitory concentration 0.125 mg/ml 12736 1.1.1.100 1,2,3,4,6-penta-O-galloyl-beta-D-glucose minimal inhibitory concentration 0.25 mg/ml 12736 1.1.1.100 1,2,3,4,6-penta-O-galloyl-beta-D-glucose compound is transported across cancer cell membrane to further down-regulate FAS and activate caspase-3 in MDA-MB-231 cells. Compared with other FAS inhibitors, including catechin gallate and morin, 1,2,3,4,6-penta-O-galloyl-beta-D-glucose involves a higher reversible fast-binding inhibition with an irreversible slow-binding inhibition, i.e. saturation kinetics with a dissociation constant of 0.59 microM and a limiting rate constant of 0.16 per min. The major reacting site of PGG is on the beta-ketoacyl reduction domain of FAS. Compound exhibits different types of inhibitions against the three substrates in the FAS overall reaction 12736
