    Description

    Daun02 is a proagent of the topoisomerase inhibitor Daunorubicin.

    IC50 & Target[2]

    Topoisomerase

     

    Daunorubicins/Doxorubicins

     

    In Vitro

    Daun02 is a prodrug, which is converted by β-galactosidase to Daunorubicin, which has been shown to reduce calcium ion (Ca2+)-dependent action potentials in neuroblastoma cells[1]. Daunorubicin is a topoisomerase inhibitor[2]. Daun02 is a good substrate for β-galactosidase (β-gal). The concentration of Daun02 producing 50% (EC50) decrease in cell viability is 0.5 μM, 1.5 μM, and 3.5 μM for T47-D, Panc02, and MCF-7, respectively[3].

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

    In Vivo

    Daun02 is a good substrate for β-gal with Km and Vmax values of 0.37 mM and 8.6 μmol/min/mg protein. At a concentration of 10-5 M, Daun02 is 79% bound to plasma protein compares to 94% for Daunomycin[3].

    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: ≥ 2.5 mg/mL (2.83 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

      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.

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

    Cell Assay
    [3]

    Murine Panc02 cells are maintained as exponentiallygrowing monolayer cultures in DMEM/F12 or RPMI-1640 medium supplemented with 10% FBS, 1% glutamine, penicillin, and streptomycin at 37°C. For cytotoxicity assay, the cells are seeded into 96-well microplates and incubated overnight. Initial experiments indicate that FBS contains low levels of intrinsic β-gal activity as evidenced by the slow conversion of Daun02 to Daunomycin; however, this is not evident for human serum. Therefore, prior to addition of Daun02, the FBS concentration is reduced from 10% to 1% for Panc02 cells. Human serum (10%) is used for the transduced human cell lines. The cells are incubated for 24 h and then MTT is added. Lysis buffer (20% SDS dissolved in 50% DMF) is added 4 h after the addition of MTT and the cells are incubated overnight. The optical density at 570 nm is determined using a BIO-RAD microplate reader. Cytotoxicity is expressed as the concentration of drug or prodrug that produced a 50% (EC50) reduction in cell viability[3].

    Animal Administration
    [3]

    Mice[3]
    Male athymic BALB/c mice (nu/nu genotype, 18-20 g) are used. Daunomycin is administered at a dose of 20 mg/kg in 100 μL normal saline solution into the tail vein. Daun02 is administered intraperitoneallyat a dose of 200 mg/kg in 200 μL vehicle. (This route is selected because the volume of drug solution, 200 μL, is too great for tail vein administration.) Tumor volume is determined bycaliper measurement in two dimensions and converted to tumor mass. Tumor growth is monitored over a period of 30 days or until the tumors has reached a mass of 5% of bodyweight (about 1 g). The animals are then killed bycarbon dioxide asphyxiation.

    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.
