Biological Activity

PIK-90 is a novel and potent PI3K inhibitor with IC50 values of 11 nM, 350 nM, 18 nM and 58 nM for p110α, p110β, p110γ and p110δ respectively. Phosphoinositide 3-kinases (PI3Ks) are among the most frequently activated signaling pathways in cancer. Inhibition with p110alpha inhibitor PIK-90 resulted in a significant reduction of chemotaxis and actin polymerization to CXCL12 and reduced migration beneath MSC (pseudoemperipolesis). In suspension and MSC cocultures, PIK-90 was potent inducers of CLL cell apoptosis.

Cell Experiment
Cell lines LN229:EGFR (PTENwt) and U87:EGFR (PTENmt) cells
Preparation method Cell proliferation assay and flow cytometry. For viability, 105 cells were seeded in 12-well plates in the presence of erlotinib, PI-103, PIK-90, rapamycin, erlotinib plus PIK-90, erlotinib plus rapamycin, erlotinib plus PIK-90, and rapamycin or erlotinib plus PI-103 for 72 h. Cell viability was determined using a WST-1 assay (Roche Molecular Biochemicals).

Animal models Human primary GBM43 cells female BALB/c nu/nu mice bearing xenografts model
Formulation DMSO:H20
Dosages 40 mg/kg
Administration daily i.p.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog

Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
