Generation of hydrogen peroxide primarily contributes to the induction of Fe(II)-dependent apoptosis in Jurkat cells by (-)-epigallocatechin gallate.
Although (-)-epigallocatechin gallate (EGCG) has been reported to induce apoptosis in a variety of tumor cells, detailed mechanisms remain to be explored. In the present study, we investigated theExpand

Inhibition of the acidification of endosomes and lysosomes by the antibiotic concanamycin B in macrophage J774.
The antibiotic concanamycin B was found to inhibit oxidized-low-density-lipoprotein(LDL)-induced accumulation of lipid droplets in the macrophage J774 at a concentration of 5-10 nM. Concanamycin BExpand

Effects of Mulberry Leaf Extract Rich in 1-Deoxynojirimycin on Blood Lipid Profiles in Humans
Mulberry leaves are rich in 1-deoxynojirimycin (DNJ), an inhibitor of α-glucosidase. We previously showed that DNJ-rich mulberry leaf extract suppressed elevation of postprandial blood glucose inExpand

Isolation, characterization and biological activities of concanamycins as inhibitors of lysosomal acidification.
Four new analogues of concanamycin family, designated concanamycins D, E, F G, were isolated from the mycelium of Streptomyces sp. A1509 by solvent extraction, silica gel column chromatography andExpand

Specific inhibition of glyceraldehyde-3-phosphate dehydrogenase by koningic acid (heptelidic acid).
A sesquiterpene named koningic acid has been isolated from a strain of Trichoderma koningii as a potent inhibitor of ATP generation in the glycolytic pathway. From experiments with both culturedExpand

Extracellular histone induces plasma hyaluronan-binding protein (factor VII activating protease) activation in vivo.
Plasma hyaluronan-binding protein (PHBP), an activator of factor VII and prourokinase, is a serine protease circulating as a single-chain proenzyme (pro-PHBP). Pro-PHBP converts to the activeExpand

Identification of koningic acid (heptelidic acid)-modified site in rabbit muscle glyceraldehyde-3-phosphate dehydrogenase.
The sesquiterpene antibiotic koningic acid (heptelidic acid) has been previously demonstrated to modify glyceraldehyde-3-phosphate dehydrogenase in specific manner, probably by binding to theExpand

Inhibition of the uptake of oxidized low-density lipoprotein in macrophage J774 by the antibiotic ikarugamycin.
The antiprotozoal antibiotic ikarugamycin was found to significantly inhibit oxidized low-density lipoprotein(LDL)-induced accumulation of cholesteryl ester in macrophage J774 at a concentration overExpand
