    Description

    SG3199 is a cytotoxic DNA minor groove interstrand crosslinking pyrrolobenzodiazepine (PBD) dimer. SG3199 is the released warhead component of the ADC payload Tesirine (SG3249)[1][2].

    IC50 & Target[1]

    Pyrrolobenzodiazepines

     

    In Vitro

    SG3199 is potently cytotoxic against a panel of human solid tumour and haematological cancer cell lines with a mean GI50 of 151.5 pM. Cells defective in DNA repair protein ERCC1 or homologous recombination repair show increased sensitivity to SG3199 and the drug is only moderately susceptible to multidrug resistance mechanisms[1].
    SG3199 is highly efficient at producing DNA interstrand cross-links in naked linear plasmid DNA and dose-dependent cross-linking is observed in cells[1].

    In Vivo

    The in vitro binding of [3H]-SG3199 to the plasma proteins of rat (Sprague Dawley), cynomolgus monkey and human at concentrations of 0.8, 5 and 50 ng/mL is determined. Plasma protein binding is high in all species; rat ~97%, cynomolgus monkey ~90% and human ~95%[1].
    Following i.v. administration at 0.1 μg/kg, 0.5 μg/kg and 1 μg/kg, SG3199 shows a very rapid clearance in rats. In the 0.5 μg/kg and 1 μg/kg dose groups, the rapid clearance was between 1000 and 1500 mL/h/kg, with a T1/2 between 8 and 42 minutes[1].

    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: ≥ 3.25 mg/mL (5.56 mM); Clear solution

      This protocol yields a clear solution of ≥ 3.25 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (32.5 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% Corn Oil

      Solubility: ≥ 3.25 mg/mL (5.56 mM); Clear solution

      This protocol yields a clear solution of ≥ 3.25 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 (32.5 mg/mL) to 900 μL Corn oil, and mix evenly.

    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.
