磷酸肌醇依赖性蛋白激酶-1(PDK1)激活剂;a phosphoinositide-dependent protein kinase-1 (PDK1) activator;PS 48已显示为PKB激酶(磷酸肌醇依赖性蛋白激酶1,PDK1)激活剂(K | d | = 10.3μM)。研究表明,该化合物选择性结合PKB激酶(PDK1)的PIF结合口袋。这是一个与ATP结合位点分开的独特区域。;PS 48 has been shown to be a PKB Kinase (phosphoinositide-dependent protein kinase-1, PDK1) activator (K|d|= 10.3 μM). Studies have indicated that this compound selectively binds to the PIF-binding pocket of PKB Kinase (PDK1). This is a distinct region separate from the ATP binding site.
