NCIt definition : An orally bioavailable, small molecule inhibitor of the delta isoform of the 110 kDa
catalytic subunit of class I phosphoinositide-3 kinase (PI3K) with potential immunomodulating
and antineoplastic activities. Idelalisib inhibits the production of the second messenger
phosphatidylinositol-3,4,5-trisphosphate (PIP3), preventing the activation of the
PI3K signaling pathway and inhibiting tumor cell proliferation, motility, and survival.
Unlike other isoforms of PI3K, PI3K-delta is expressed primarily in hematopoietic
lineages. The targeted inhibition of PI3K-delta is designed to preserve PI3K signaling
in normal, non-neoplastic cells.;
