PIK-90 is a potent and cell permeable phosphoinositide 3-kinase (PI3K) inhibitor.  Through this action, PIK-90 reduces chemotaxis and induces apoptosis in chronic lymphocytic leukemia B cells. It also blocks proliferation of glioma cells in vitro.2 By inhibiting P110α, PIK-90 blocks insulin-stimulated phosphorylation of Akt in L1 adipocytes and L6 myotubes, preventing activation of the mTORC1 pathway.

In vitro, PIK-90 also inhibits p110β, p110δ, PI3KC2α, PI3KC2β, hsVPS34, PI4KIIIα, PI4KIIIβ, ATR, ATM and mTORC1 with IC50s of 350 nM, 58 nM, 47 nM, 64 nM, 830 nM, 830 nM, 3.1 μM, 15 μM, 610 nM and 1.05 μM, respectively. To determine the effects of PIK-90 on chronic lymphocytic leukemia (CLL) cell viability, CLL cells from different patients are incubated with various concentrations of PIK-90 (1 μM and 10 μM) for 24, 48, and 72 hours. PIK-90 reveals the strong apoptosis-inducing effects at both concentrations and at all different time points. Using a concentration of 10 μM, PIK-90 reduces the viability of CLL cells to 51.1% plus or minus 6.6% at 24 hours, whereas 1 μM PIK-90 reduces the viability to 77.8% plus or minus 6.4%
