体外実験

Treatment with CBL-0137 leads to complete absence of living cells at concentrations above 2.5 μM. CBL-0137 causes a greater reduction in the number of colonies formed of not only MiaPaCa-2 cells when combined with Gemcitabine (HY-17026), but also Gemcitabine-resistant PANC-1 cells. Treatment of human pancreatic cancer cells with CBL-0137 results in a dose dependent reduction of protein and mRNA levels of RRM1 and RRM2. CBL-0137 is able to prevent Gemcitabine induced expression of RRM1 and RRM2 on mRNA and protein levels^[1].

体内実験

The CBL-0137 monotherapy group and the CBL-0137-Gemcitabine combination group samples show large necrotic fields, numerous apoptotic bodies and loss of tumor cells. Sub-optimal doses of 50 to 60 mg/kg CBL-0137 causes similar enhancement of Gemcitabine antitumor activity as that produced by the maximum tolerated dose (MTD) of 90 mg/kg as indicated by the lack of statistically significant differences among the combination groups. CBL0137 inhibits FACT function through depletion of the pool of active FACT involved in transcription elongation^[1].
CBL-0137, given by oral gavage at a nontoxic dose of 30 mg/kg per day on a 5 days on/2 days off schedule, suppresses tumor growth in xenografts of colon (DLD-1), renal cell carcinoma (Caki-1), and melanoma (Mel-7) tumor cell lines and transplanted surgical samples from patients with pancreatic ductal adenocarcinoma^[2].

Kinase Assay^[1]

MiaPaca2 and BxPC-3 cells are treated with CBL-0137for 4 or 24h. Cells are harvested in 1× Cell Culture Lysis Reagent containing protease and phosphatase inhibitors. Lysates 5 to 20 μg are separated on SDS-PAGE gels and transferred to PVDF membranes. Blots are probed with antibodies specific for SSRP1, SPT16, RRM1, and RRM2. GAPDH is used as a loading control. Proteins are visualized using ECL kit^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Assay^[1]

Cells are resuspended in serum free Dulbecco's Modified Eagle Medium (DMEM) and treated with different concentrations of CBL-0137 for 1h. After that 10⁵ from each treatment condition are plated in 3 wells of 6-well plate in 2mL of serum-free DMEM/F12 medium supplemented with 0.4% BSA, 0.2×B27, 10 ng/mL recombinant EGF and containing 0.25% agarose. 10³ cells from each treatment condition are plated in 3 wells of 6-well plate in regular FBS containing medium. Colonies are counted using inverted microscope 7 to 15 days after plating^[1].

Animal Administration^[1]

10-week old female athymic nude mice (n=8 per treatment group) are deeply anesthetized with ketamine/xylazine. Using laparotomy, 2× 10⁶ PANC-1 cells are inoculated into the tail of the pancreas of each mouse. Two weeks following inoculation (tumor presence confirmed by ultrasound), treatment commenced. The following regimens are used: 1) vehicles, 100mg/kg captisol i.v. and sterile water via gavage, 2) 50 to 90 mg/kg CBL-0137 in 100 mg/mL captisol i.v. delivered via tail vein once per week, 3) 10 to 20 mg/kg CBL-0137 p.o. via oral gavage, 5 days on/2 days off, 4). Tumor measurement is done with digital calipers. Tumor volume is calculated using the equation L×W²/2 where L is the longest dimension and W is the dimension perpendicular to W. Mice are followed until at least one tumor per mouse reached 1000 mm³ or 90 days from start of treatment, whichever comes first^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
