生物活性
Miransertib（ARQ 092）是一种有效的选择性和变构型 Akt 抑制剂，对 Akt1，Akt2，Akt3 的 IC50 分别为 2.7 nM，14 nM 和 8.1 nM。
In vitro: ARQ-092 demonstrates high enzymatic potency against Akt1, Akt2 and Akt3, as well as potent cellular inhibition of Akt activation and the phosphorylation of the downstream target PRAS40. ARQ-092 shows strong affinity for un-phosphorylated fulllength Akt1 and potently inhibited the phosphorylated form of full-length Akt isoforms. In a large panel of cell lines derived from various tumor types, ARQ-092 shows potent anti-proliferative activity in cell lines containing PIK3CA/PIK3R1 mutations compared to those with wild-type (wt) PIK3CA/PIK3R1 or PTEN loss. ARQ-092 shows excellent inhibition of p-Akt (S473) and p-Akt (T308) in both AN3CA and A2780 cells.
In vivo: ARQ-092 (po at 100 mg/kg, iv at 5 mg/kg) in a mouse pharmacokinetic study shows an oral bioavailability of 23%. ARQ-092 results in 99%, 95% and 58% reductions in p-Akt (S473), p-Akt (T306) and p-PRAS40 (T246), respectively, after tumor-bearing mice are treated with 100 mg/kg po. The inhibition of phosphorylation is sustained at eight hours. The plasma concentration of ARQ-092 at one hour is 2.1 μM and decreased to 0.26 μM at 8 hours, while in the tumor, the concentration is 21.0 μM at one hour and 9.6 μM at 8 hours. Treatment of the SHP2Y279C/+mice with ARQ-092 normalizes the hypertrophic cardiomyopathy (HCM) phenotype as early as 2 weeks following treatment, with levels comparable to those in SHP2+/+at this time point.

| 细胞系 | AN3CA and A2780 cells |
| 方法 | AN3CA and A2780 cells are obtained from the ATCC. AN3CA cells are cultured in DMEM, and A2780 cells are cultured in RPMI supplemented with 10% FBS, 100 units/mL Penicillin, 100 μg/mL Streptomycin, and 2 mM Glutamine at 37 °C under 5% CO2. Cells are plated in 96-well plates at 2,000-10,000 cells/well, cultured for 24 h, and treated with the test compound for 72 h at a final DMSO concentration no greater than 0.5% v/v. PMS stock reagent (0.92 mg/mL in DPBS) is diluted 20-fold in MTS stock reagent (2 mg/mL in DPBS), and this MTS/PMS mixture is diluted 5-fold into each well of the 96-well plate. The plates are incubated for 3-4 h, and the absorbance of formazan is measured at 490 nm. The data are normalized to the untreated controls, the dose-response curves are fit to a four-parameter logistic equation, and the IC50 values are determined. All IC50 values reported are the geometric mean of at least two independent determinations. |

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。
