CAY10505 is a potent PI3Kγ inhibitor with an IC50 of 30 nM. Phosphoinositide 3-kinase γ (PI3Kγ) is expressed primarily in hematopoietic cells and plays several important roles in immunity. CAY10505 also prevents other α, β, and δ isoforms with IC50 of 0.94, 20, and 20 μM, respectively. CAY10505 significantly inhibits only the unrelated casein kinase 2 (CK2, IC50 = 20 nM). CAY10505 also suppress the phosphorylation of the PI3K substrate PKB/Akt in murine macrophages (IC50 = 228 nM). Oral administration of CAY10505 decreases neutrophil recruitment in mice to an extent that is comparable to that observed in PI3Kγ-deficient mice.

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.
