Description

Cilostamide is a selective and potent PDE3 inhibitor, with IC50s of 27 nM and 50 nM for PDE3A and PDE3B, respectively, and has antithrombotic and anti-intimal hyperplastic activity.

IC50 & Target

IC50: 27 nM (PDE3A), 50 nM (PDE3B)[1]

In Vitro

Cilostamide is a selective and potent PDE3 inhibitor, with IC50s of 27 nM and 50 nM for PDE3A and PDE3B, respectively, and has antithrombotic and anti-intimal hyperplastic activity. Cilostamide weakly inhibits PDE2, PDE4, PDE5, PDE7, and PDE1, with IC50s of 12.5, 88.8, 15.2, 22.0 and > 300 μM, respectively. Cilostamide potently inhibits thrombin-induced platelet aggregation (IC50, 1.1 μM)[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: ≥ 1.67 mg/mL (4.88 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: ≥ 1.67 mg/mL (4.88 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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]

Platelet aggregation is investigated in the assay. Washed platelets (200 μL of a suspension containing 3 × 108 cells/mL in Tyrode HEPES buffer, pH 7.4) are incubated for 3 min at 37°C in the presence or absence of different concentrations of OPC-33540, OPC-33536, and Cilostamide alone, or in combination with 3 nM PGE1, followed by incubation with 5 μL of 2 units/mL of thrombin for 5 min at 37°C. The intensity of light transmitted over 5 min is measured using a PAM-8C aggregometer. The inhibition rate is calculated by comparison of maximum aggregation rates with the control value[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.
