In Vitro | Danusertib (0.01 to 50 μM) significantly decreases viability of C13 and A2780cp cells. The IC50s are 10.40 and 1.83 μM for C13 cells, and 19.89 and 3.88 μM for A2780cp cells after 24- and 48-h treatment. Danusertib induces cell cycle arrest in G2/M phase in C13 and A2780cp cells. Danusertib treatment results in a marked increase in the percentage of cells arrested in G2/M phase and an accumulation of polyploidy in C13 and A2780cp cells. Danusertib demotes the expression of CDK1/CDC2 and cyclin B1 but promotes the expression of p21 Waf1/Cip1, p27 Kip1, and p53. Danusertib induces autophagy in C13 and A2780cp cells with the involvement of PI3K/Akt/mTOR signaling pathway[1]. PHA-739358 strongly inhibits proliferation of all leukemic cell lines tested, with IC50 values ranging from 0.05 μM to 3.06 μM. PHA-739358 induces antiproliferative effects in BaF3-p210 cells, including IM-resistant M351T, E255K, and T315I mutants. PHA-739358 (5 μM) reduces phosphorylation of CrkL in BaF3-p210 wt cells and IM-resistant mutants[2]. Danusertibsertib leads to cell-cycle arrest and completely inhibits cell proliferation of the GEP-NET cells in vitro[3]. |
In Vivo | PHA-739358 (15 mg/kg twice a day, i.p.) and IM are well tolerated, and significantly inhibit proliferation of K562 cells andvirtually suppressed tumor growth during the 10-day treatment period[2]. In a subcutaneous murine xenograft model, danusertibsertib (2×15 mg/kg/d, i.p.) significantly reduces tumor growth in vivo compared with controls or mice treated with streptozotocine/5-fluorouracil[3]. |
Cell Assay | The MTT assay is performed to examine the effect of danusertib on the viability of C13 and A2780cp cells. Briefly, cells are seeded in 96-well culture plates at a density of 8×l03 cells/well. After cells are attached, the cells are treated with danusertib at different concentrations (0.01-50 μM). The control cells receive the vehicle only. After 24-h incubation, 10 μL MTT (5 g/L) is added to each well and cultured for another 4 h. Then, the media is carefully aspirated and 100 μL DMSO is added. The absorbance at the 450 nm wavelength is measured with a Synergy H4 Hybrid microplate reader. The IC50 values are determined using the relative viability over danusertib concentration curve using GraphPad Prism 6.0. |
Animal Admin | To evaluate the efficacy and toxicity of PHA-739358 in vivo, a subcutaneous animal model for CML is used; 5×107 K562 cells are injected into the flanks of female SCID mice and tumor growth is monitored daily by palpation. On day 7, when tumors reach an estimated weight of 100 to 150 mg, animals are assigned to 3 experimental groups by random selection and receive the following treatment for a period of 10 days: group 1, control, vehicle solution (7 mice); group 2, PHA-739358 twice a day intraperitoneally at a dose of 15 mg/kg (7 mice); and group 3, IM twice a day per os at 100 mg/kg. Tumor growth is assessed by caliper, and tumor weight is calculated according to the following formula: Tumor weight=[length (mm) × width2 (mm)]/2. Toxicity is monitored by changes in body weight and vitality of the animals. |
