Description

Succimer is a widely used chelating agent for the treatment of Pb poisoning.

In Vivo

Succimer is a widely used chelating agent for the treatment of Pb poisoning. Red blood cells (RBCs) from lead exposed animals treated with NAC or Succimer are shown to have significantly higher glutathione (GSH) levels and diminished malondialdehyde (MDA) levels when compare to the lead group. Succimer administration also results in decreased glucose 6-phosphate dehydrogenase (G6PD) activity in RBCs from lead exposed animals[1]. Succimer treatment produces a significant reduction in blood lead levels for both lead exposure conditions: the High Pb-succ group has blood lead levels that are 27% of the blood lead levels of the High Pb group at the end of treatment. Succimer is effective in substantially reducing brain lead, as brain lead levels in the High Pb-succ group are 37% of levels in the High Pb group[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: ≥ 2.5 mg/mL (13.72 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.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (13.72 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 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.

Animal Administration
[1]

All experiments are performed with Fisher 344 male rats weighing 75 to 100 g. The animals are randomized into four groups. Group I (n=11) serves as the control and is given only standard rat chow and water for 6 weeks. Group II (n=11) receives 2000 ppm lead acetate in its drinking water for 5 weeks and, during the 6th week, this group receives water. Group III (n=6) receives 2000 ppm lead acetate in its drinking water for 5 weeks and, during the 6th week, these animals receive 800 mg/kg/day NAC dissolved in water. Group IV (n=6) is treated like group III, except that it receives 90 mg/kg/day Succimer during the last week. At the end of the 6th week, after overnight fasting, the animals are anesthetized with metofane and blood samples are collected via intracardiac puncture using heparin as an anticoagulant. Plasma and the buffy coat are removed by centrifugation for 10 min at 3000 rpm. The RBCs are washed three times with an equal volume of cold saline[1].

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.
