Cucurbitacin E is a CDK1 inhibitor that significantly inhibits the activity of the cyclin B1/CDC2 complex. Cucurbitacin E also induces PANoptosis in adrenocortical carcinoma cells in a ZBP1-dependent manner. Cucurbitacin E exhibits synergistic effects with Mitotane (HY-13690); when used in combination, they effectively eliminate tumors.

In Vitro

Cucurbitacin E (2.5-7.5 μM; 6-24 h) induces morphological changes in primary colon cancer cells and inhibits tumor growth by arresting the cell cycle at the G₂/M phase through the induction of GADD45γ gene expression and the blockade of the Cyclin B1/CDC2 complex in primary CRC cells^[1].

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

In Vivo

Cucurbitacin E (0.5 mg/kg) induces a significant reduction in body weight and a decrease in fat pad weight in HFD-MetS mice; specifically, total body fat mass is decreased by 55%, and the degree of central obesity is reduced to 50% of that of the control group^[2].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: 2.5 mg/mL (4.49 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (4.49 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol

Cell Assay^[1]

The colorectal cancer (CRC) cells are seeded into 96-well culture plates at 5000 cells/well. The cells are treated with 0, 2.5, 5, and 7.5 μM Cucurbitacin E for 1-3 days. MTT dye (1 mg/mL) is added to each well for at least 4 h of treatment. The reaction is stopped by the addition of DMSO, and optical density is measured at 540 nm on a multi-well plate reader. Background absorbance of the medium in the absence of cells is subtracted. All samples are assayed in triplicate, and the mean for each experiment is calculated. Results are expressed as a percentage of control, which is considered as 100%. Each assay is carried out in triplicate, and the results are expressed as the mean^[1].

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

Animal Administration^[2]

Mice^[2]
C57BL/6 male mice are used. The mice are designated as metabolic syndrome mice (HFD-MetS-mice). Briefly, the mice are randomly assigned into two groups according to their diet for 8 weeks (n = 10-12): high fat diet group (HFD) (60% fat, 20% carbohydrate, 20% protein) or the matched low fat, standard diet group (SD) (10% fat, 70% carbohydrate, 20% protein). After eight weeks on high fat diet, the mice with significant obese phenotype and fasting blood glucose levels ≥126 mg/dL are considered MetS mice. The MetS mice are continued on the HFD throughout the study. The MetS mice are then randomly divided into three additional groups, according to the treatment administered by oral gavage for 10 weeks (n=10-12): a low dose 0.25 mg/kg/day of Cucurbitacin E designated as HFD+Cucurbitacin E (L) or high dose 0.5 mg/kg/day of Cucurbitacin E, designated as HFD+Cucurbitacin E (H) or 50 mg/kg/day Orlistat (HFD+Orlistat). Animals on SD are administered 0.5% CMC by oral gavage^[2].

Help & FAQs

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.
