Description

Carmustine is an antitumor chemotherapeutic agent, which works by akylating DNA and RNA.

IC50 & Target

DNA Alkylator[1]

In Vitro

Carmustine is an antitumor chemotherapeutic agent. Carmustine (8, 80, and 800 μM) decreases N-acetyltransferase (NAT) activities for 2-aminofluorene (AF) and p-aminobenzoic acid (PABA) in rat glial tumor cytosol and intact cells. In rat glial tumor cells, the DNA-AF adduct increases, and carmustine decreases the formation of DNA-AF adduct[1].

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

In Vivo

Carmustine (BCNU; 25 mg/kg, i.p.) causes higher levels of the rhe ratio of liver weight to body weight and plasma conjugated bilirubin, and lower biliary flow, oxidised glutation levels (GSSG) and reduced glutation (GSH)/GSSG values compared with control rats[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

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

    Solubility: ≥ 2.08 mg/mL (9.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (9.72 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Kinase Assay
[1]

The determination of Acetyl-CoAdependent N-acetylation of 2-aminofluorene (AF) and p-aminobenzoic acid (PABA) are performed. Incubation mixtures in the assay system consists of a total volume of 90 μL: glial tumor cells cytosols, diluted as required, in 50 μL of lysis buffer (20 mM Tris/HCl, pH 7.5, 1 mM DTT and 1 mM EDTA), 20 μL of an Acetyl-CoA recycling mixture of 50 mM Tris-HCl (pH7.5), 0.2 mM EDTA, 2 mM DTT, 15 mM acetylcamitine, 2U/mL carnitine acetyltransferase, and AF or PABA at specific concentrations. The reactions are started by addition of 20 μL of Acetyl-CoA. The control reactions have 20 μL distilled water in place of Acetyl-CoA. For the single point activity measurements, the final concentration of AF or PABA is 0.1 mM and AcCoA is 0.5 mM. The reaction mixtures with or without specific concentrations of Carmustine and lomustine are incubated at 37°C for 10 min and stopped with 50 μL of 20% trichloroacetic acid for the PABA reactions, and 100 μL of acetonitrile for the AF reactions. All of the reactions (experiments and controls) are run in triplicate[1].

Animal Administration
[2]

Rats[2]
Individual rats are weighted prior to enter the study; their weights are recorded, and they are randomLy assigned to four groups. Group I (saline group); This group consists of 12 rats. These rats are injected with 2 mL/kg of saline intraperitoneally (IP) 48 h before the study, being included by the study 48 h later. Group II (corn oil group) consists of 15 rats. These rats are injected with 2 mL/kg of corn oil (vehicle) IP 48 h before the study. Group III (Carmustine group) consists of 16 rats. These rats are injected with 1 mL per day of saline IP, administered at the same hour of the day as a single-dose for 3 days. Twelve hours after the first dose of saline, corn oil 2 mL/kg + Carmustine 25 mg/kg IP are injected, and the rats are included in the study 48 h after the administration of corn oil + Carmustine. Group IV (trimetazidine group) consists of 12 rats. These rats are injected with 2.5 mg/kg per day of trimetazidine (TMZ) IP, administered at the same hour of the day as a single-dose for 3 days. 12 h after the first dose of TMZ, corn oil 2 mL/kg + Carmustine 25 mg/kg IP are injected, and the rats are included in the study 48 h after the administration of corn oil + Carmustine[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.
