生物活性
AS-604850 is a selective, ATP-competitive PI3Kγ inhibitor with IC50 of 0.25, >20, >20, and 4.5 μM for the human recombinant γ, δ, β, and α isoforms, respectively. AS-604850 shows no notable activity against a wide array of protein kinases at 1 μM. AS-604850 inhibited MCP-1-mediated monocyte chemotaxis with an IC50 value of 21 μM and reduced RANTES-induced peritoneal neutrophil recruitment in a murine model of leukocyte chemotaxis with an ED50 value of 42.4 mg/kg.

| 方法 |
Treating hepatocyte cultures with diluent (DMSO), 25 μM TLC, 250 μM TCDC, 50 μM GCDC, or 50 ng/ml Fas for 2-4 hours HepG2-Ntcp and treating Huh7-Ntcp cells with DMSO, 20 μM TLC, 75 μM TCDC or GCDC, 200 μM etoposide or 200 ng/ml TNFa plus 28 ng/ml actinomycin D for 2-4 hours. Using fluorescent staining to determine morphologically the number of apoptotic cells expressing as % of cells . Apoptosis is confirmed in human cell lines by determination of caspase-3/-7 activity and in rat hepatocytes by detection of the 17 kDa proteolytic cleavage fragment of caspase-3 by immunoblotting; equal protein loading is monitored by immunoblotting for actin. |

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。
