Miransertib (ARQ-092) is a potent, orally active, selective and allosteric Akt inhibitor with IC50s of 2.7 nM, 14 nM and 8.1 nM for Akt1, Akt2, Akt3, respectively. Miransertib is also a potent the AKT1-E17K mutant protein inhibitor and has the potential for PI3K/AKT-driven tumors and Proteus syndrome research. Miransertib is effective against Leishmania.
In a large panel of cell lines derived from various tumor types, Miransertib (ARQ-092
Compound 21a) shows potent anti-proliferative activity in cell lines containing PIK3CA/PIK3R1 mutations compared to those with wild-type (wt) PIK3CA/PIK3R1 or PTEN loss. Miransertib shows excellent inhibition of p-Akt (S473) and p-Akt (T308) in both AN3CA and A2780 cells. The inhibition of the downstream protein p-PRAS40 (T246) is observed with Miransertib (IC50=0.31 μM)[1]. Miransertib is markedly effective against intracellular amastigotes of L. donovani or L. amazonensis-infected macrophages. Miransertib also enhances mTOR dependent autophagy in Leishmania-infected macrophages[2].
Miransertib (ARQ-092
Compound 21a) shows good absolute oral bioavailability in rats (5 mg/kg) and monkeys (10 mg/kg) with F values of 62% and 49%, respectively. The half-life is longer in rats compared to monkeys with t1/2 values of 17 h in rats versus 7 h in monkeys. The Cmax is 198 ng/mL and 258 ng/mL and the AUCinf was 5496 h ng/mL and 2960 h ng/mL in rats and monkeys, respectively[1]. Miransertib (ARQ-092
Compound 21a) inhibits tumor growth in a human xenograft mouse model of endometrial adenocarcinoma[1].
Mice[2] SHP2Y279C/+ mice are used. Only male progeny are used for the experiments herein and all mice are maintained on outbred C57BL6/J backgrounds, backcrossed for more than 10 generations. Either vehicle or Miransertib (100 mg/kg body weight) is then daily administered by oral gavage for 4 weeks. Administration began at 12 weeks of age (after established hypertrophy is indicated), and continued for 4 weeks, until the mice reach 16 weeks of age. As controls, SHP2+/+ and SHP2Y279C/+ mice are treated with vehicle alone.
Anti-proliferative cellular assays are conducted using the CellTiter Non-Radioactive Cell Proliferation Assay, which utilizes the production of formazan from a tetrazolium compound by live cells. AN3CA and A2780 cells are obtained from the ATCC. AN3CA cells are cultured in DMEM, and A2780 cells are cultured in RPMI. 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[1].
