Description

Bergamottin is a potent and competitive CYP1A1 inhibitor with a Ki of 10.703 nM.

IC50 & Target

Ki: 10.703 nM (CYP1A1)[1]
IC50: 0.192±0.029 μM (CYP1A1), 5.077±0.31 μM (CYP1A2), 4.535±0.092 μM(CYP2B2), 9.495±0.979μM (CYP2B1)[1].
In Vitro

Bergamottin is a competitive inhibitor of CYP1A1. Bergamottin inhibits CYP1A1, CYP1A2, CYP2B1, and CYP2B2 with IC50s of 0.192±0.029 μM, 5.077±0.31 μM, 9.495±0.979 μM, 4.535±0.092 μM, respectively[1]. Bergamottin has potent antiproliferative effects on the A549 cells. Bergamottin shows both concentration-dependent as well as time‑dependent growth inhibitory effects against these cells. Bergamottin also inhibits the clonogenic activity of the A549 cancer cells by reducing the number of cancer colony forming cells. A reduction in clonogenicity also follows the concentration dependence on Bergamottin[2].

In Vivo

The anticancer efficacy of Bergamottin under in vivo conditions using female BALB/c nude mice (a total of 20 mice are used) is determined. Tumors are induced in the mice by injecting non-small cell lung cancer A549 cells (1×106 cells/mouse). After tumor formation, the mice are sacrificed and tumors are removed and their weights and volumes are calculated. The results show that 25, 50 and 100 mg/kg Bergamottin injection reduce the tumor weight from 1.61 g in the PBS-treated group (control) to 1.21, 0.42 and 0.15 g, respectively. Tumor weight in the nude mice is reduced much more significantly in the highest-concentration Bergamottin group (100 mg/kg body weight) compared with the vehicle group (P<0.05). Likewise, 25, 50 and 100 mg/kg Bergamottin injection reduces the tumor volume from 2.2 cm3 in the PBS-treated group (control) to 1.71, 1.1 and 0.51 cm3, respectively. The periodic measurement of the tumor xenograft volume indicates that the tumor volume in the nude mice is reduced considerably in the highest-concentration Bergamottin group (100 mg/kg body weight) compared with the vehicle group (P<0.05)[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

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

    Solubility: 2.5 mg/mL (7.39 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (7.39 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.

Kinase Assay
[1]

CYP1A1 Supersomes and different concentrations of 7-ethoxyresorufin (ER) are used to determine CYP1A1 enzymatic kinetics. A typical Michaelis-Menten curve is found. The final reaction mixture contains: 1 pmol CYP1A1, 0.5 mM NADPH, different ER concentrations and 0, 4, 8 and 16 nM of Bergamottin (BG). The reaction is started with the addition of NADPH. Kinetic constants are obtained by a nonlinear regression analysis of experimental data fitted to Michaelis-Menten equation with competitive-type inhibition. Kinetic analysis is also shown by using the Lineweaver-Burk, Dixon and replot of the slopes of the Dixon plot[1].

Cell Assay
[2]

Inhibition of cell proliferation by Bergamottin is measured by the MTT assay. Briefly, the human lung adenocarcinoma cancer A549 cells are plated in 96-well culture plates (1×105 cells/well). After 24 h of incubation, the cells are treated with Bergamottin (0, 5, 10, 25, 50, 75 and 100 μM) for 24 and 48 h, MTT solution (10 mg/mL) is then added to each well. After a 4-h incubation, the formazan precipitate is dissolved in 100 μL DMSO, and then the absorbance is measured in an automated microplated reader at 570 nm. The cell viability ratio is calculated. Cytotoxicity is expressed as the concentration of Bergamottin needed to inhibit cell growth by 50% (IC50 value)[2].

Animal Administration
[2]

Mice[2]
Female BALB/c nude mice (six weeks old) (a total of 20 are obtained) are maintained with water and food ad libitum in a pathogen-free environment with a 12 h light and 12 h dark cycle in an animal care facility. Human non‑small cell lung carcinoma A549 cells (2×106 cells/mouse) are injected into the right axilla of the nude mice (5 mice/group) to create tumors in the mice. Subsequent to tumor development, the mice are divided into 4 groups and treated with Bergamottin injected intraperitoneally. The control group in the study is treated with an equal amount of PBS while the other three groups are treated with 25, 50 and 100 mg/kg of Bergamottin. Afterwards, the mice are sacrificed after 18 days, and the tumor weight and volume of each mouse are evaluated. Tumor length and width are measured using a Vernier caliper and the tumor volume (TV) is calculated[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
