is a highly selective PI3K inhibitor with a submicromolar inhibition. It is well that the pyridopyrazine core of D-106669 is substituted by an aniline residue, base scaffold of a more advanced derivative AEZS-126 which is also identified as a inhibitor with an IC50 of < 10nM for PI3K alpha. When was given at oral dose of D-106669 presented certain inhibitory activity in A549 xenografts mouse model. optimized compound of NVP-BEZ235 is NVP-BEZ235 that is also a PI3K alpha
