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.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
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。
