GSK1059615 is a potent, ATP-competitive inhibitor of PI 3-kinase alpha (PI3Kα) with IC50 of 2 nM. Phosphatidylinositol-3 kinases (PI3K) are critical for malignant cellular processes including growth, proliferation, and survival. GSK1059615 is also a novel inhibitor of PI3Kβ, PI3Kδ, PI3Kγ and mTOR with IC50 of 0.6 nM, 2 nM, 5 nM and 12 nM, respectively. GSK1059615 (25 mg/kg) effectively inhibits tumor growth in xenograft mice models of BT474 or HCC1954 breast cancer cells and attenuates MAPK signaling.

| 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 Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 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 Compound A of 10 mg/kg.
