STRUCTURE DETERMINANTS OF PHOSPHOINOSITIDE 3-KINASE INHIBITION BY WORTMANNIN, LY294002, QUERCETIN, MYRICETIN AND STAUROSPORINE
OverviewOverview
The specific phosphoinositide 3-kinase (PI3K) inhibitors wortmannin and, LY294002 have been invaluable tools for elucidating the roles of these, enzymes in signal transduction pathways. The X-ray crystallographic, structures of PI3Kgamma bound to these lipid kinase inhibitors and to the, broad-spectrum protein kinase inhibitors quercetin, myricetin, and, staurosporine reveal how these compounds fit into the ATP binding pocket., With a nanomolar IC50, wortmannin most closely fits and fills the active, site and induces a conformational change in the catalytic domain., Surprisingly, LY294002 and the lead compound on which it was designed, quercetin, as well as the closely related flavonoid myricetin bind PI3K in, remarkably different orientations that are related to each other by 180, ...
