Cell experiment: | MTT assays are used to assess proliferation of Abrams, D17, and Moresco canine OSA cells following treatment of PTC-209 alone and in combination with Dox or Carbo. 500 cells are seeded in 96 well plates with DMEM/10%FBS and allowed to adhere overnight (16-18 hrs). For single treatment PTC-209 experiments, cells are incubated with drug for 72hrs at final concentrations of 0, 200, 300, 400, 500, and 600nM. For combination treatment experiments, cells are incubated with drug(s) for 72hrs at the following final concentrations: PTC-209 (0, 100, 200, and 500 nM), Dox (0, 3, and 30 nM), Carbo (0, 3, and 30 μM). Vehicle controls include DMSO (PTC-209), 0.9% saline (Dox), and water (Carbo). Additional controls included untreated (UT) cells (no veh or drug) and wells containing media (DMEM/10%FBS) alone (to assess background absorbance). Briefly, MTT solution is added to each well at a final conc. of 0.5mg/mL and incubated at 37°C for 4hrs. 200uL of DMSO is added to dissolve formazin crystals and absorbance is measured at 570nM and 630nM (reference wavelength) using a spectrophotometer (Spectramax 190). 6 wells per group are used for PTC-209 single treatment experiments, and 4 wells per group are used for combination treatment experiments, and all experiments are repeated twice. Statistical analysis is performed using 2-way ANOVA with Tukey’s multiple comparisons test. |
Animal experiment: | Mice[1] For the experiments where mice are dosed with the drug in vivo, tumor cells are injected subcutaneously into nude mice (male, aged 8-10 weeks), and when the tumors reach an approximate 0.2 cm3 volume, PTC-209 is administered subcutaneously once a day at a dose of 60 mg per kg body weight (control animals received equal volumes of vehicle, 14% DMSO, 36% polyethylene glycol 400 and 50% polypropylene glycol). Tumor volume measurements are recorded every 3-7 d until the endpoint is reached. |

PTC-209 HBr is the hydrobromide salt of PTC-209, a potent and selective BMI-1 inhibitor (IC50 = 0.5μM). It irreversibly impairs the colorectal tumor growth. [1]
BMI-1 is a component of polycomb repressive complex 1 (PRC1) and act as an epigenetic chromatin modifier for a variety of genes. [1]
PTC-209 inhibited both UTR-mediated reporter expression and endogenous BMI-1 expression in HCT116 (human colorectal cell) and HT1080 (human fibrosarcoma tumor cell) in a dose dependent manner. In addition, the inhibitory effect of PTC-209 was not from its cytotoxicity. PTC-209 also specifically reduced PRC1 activity. [1]
Viable colorectal cancer cell samples treated with PTC-209 ex vivo were injected back to the recipient mice in vivo, the mice exhibited reduced or no tumor growth comparing with the control groups. Thus PTC-209 irreversibly impaired colorectal cancer-initiating cells. Furthermore, in contrast with the control groups, tumor volume was significantly reduced in the colorectal tumor cell transplanted mice following PTC-209 administration. [1]
