生物活性
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.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
