SKF-83566 is a potent, blood-brain permeable and orally active D1-like dopamine receptor (D1DR) antagonist and a weaker competitive antagonist at the vascular 5-HT2 receptor (Ki=11 nM). SKF-83566 is a competitive DAT (dopamine transporter) inhibitor with an IC50 of 5.7 μM. SKF-83566 also shows selective inhibition for adenylyl cyclase 2 (AC2) over AC1 and AC5 in the isolated rabbit thoracic aorta. SKF-83566 can be used for research of parkinson’s disease and nicotine craving alleviation.

Description

SKF-83566 is a potent, blood-brain permeable and orally active D1-like dopamine receptor (D1DR) antagonist and a weaker competitive antagonist at the vascular 5-HT2 receptor (Ki=11 nM)[1][3]. SKF-83566 is a competitive DAT (dopamine transporter) inhibitor with an IC50 of 5.7 μM[2]. SKF-83566 also shows selective inhibition for adenylyl cyclase 2 (AC2) over AC1 and AC5 in the isolated rabbit thoracic aorta[4]. SKF-83566 can be used for research of parkinson’s disease and nicotine craving alleviation[5].

In Vitro

SKF-83566 (0.1 μM-10 μM) causes a concentration-dependent increase in peak evoked extracellular DA concentration ([DA]o)?evoked by single-pulse stimulation, with a maximum 65% increase in peak evoked [DA]o with 5 μM. The EC50 value of this effect of SKF-83566 is 1.3 μM[2].
SKF-83566 inhibited [3H]DA uptake with an IC50?of 5.73 μM. Moreover, SKF-83566 more potently inhibits the binding of [3H]CFT, with an IC50?of 0.51 μM in [3H]DA uptake and [3H]CFT binding studies[2].
Similarly, in LLc-PK-rDAT cell, SKF-83566 also inhibits [3H]CFT binding with an IC50?of 0.77 μM in LLc-PK-rDAT cell membrane preparations[2].

In Vivo

SKF 83566 (oral administration; 20 μg/mL; 7 days) alone has no effects on altering LTP (115%). However, combinnation of SKF 83566 and nicotine significantly blocks the enhancement of long-term synaptic potentiation (LTP) induced by pretreatment with nicotine (SKF 83566+nicotine+cocaine, 120%; nicotine+cocaine, 143%)[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: ≥ 2.5 mg/mL (7.52 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 (7.52 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.

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.
