Virtual docking screening and QSAR studies to explore AKT and mTOR inhibitors acting on PI3K in cancers

open access: yesContemporary Oncology, 2020
The phosphoinositide 3-kinase (PI3K) pathway is an important regulator of cell proliferation and metabolism. PI3K activation initiates a signal transduction cascade, of which the major effectors are the kinases AKT and mTOR.
