Description

PF-05180999 (PF-999) is a phosphodiesterase 2A (PDE2A) inhibitor, with an IC50 of 1.6 nM.

In Vitro

PF-05180999 is a phosphodiesterase 2A (PDE2A) inhibitor, with an IC50 of 1.6 nM. PF-05180999 binds to the rat, dog and monkey PDE2A, with Kis of 4.2, 8.4, and 5.5 nM and IC50s of 2.6, 5.2, and 3.4 nM, respectively. PF-05180999 shows weak activity against PDE, with IC50s of 2.03 μM (PDE10A1), 26.969 μM (PDE7B), 50.09 μM (PDE11A4), and >56.25 μM (PDE1B1, PDE3A1, PDE4D3, PDE5A1, PDE6 (bovine), PDE8B, PDE9A1), respectively. PF-05180999 is also a weak inducer of CYP3A4, and with no direct inhibition of human recombinant cytochrome P450 (CYP) enzymes (1A2, 2B6, 2C8, 2C9, 2C19, 2D6, and 3A) and no induction of CYP1A2[1].

In Vivo

PF-05180999 (Compound 30; 0.032-0.32 mg/kg mg/kg, s.c.) dramatically reduces the working memory errors produced by ketamine in a working memory radial arm maze (RAM) model in rats. PF-05180999 causes acute and exposure-dependent elevation in the accumulation of cGMP bulk levels in the cortex, striatum, and hippocampus, but with no changes in cAMP and the associated downstream phospho-cAMP response element-binding protein (p-CREB) in mice[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 (6.03 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 (6.03 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]

Rats[1]
Male Sprague-Dawley rats (weighing 250-320 g) under urethane anesthesia at 1.5 g/kg intraperitoneal (ip) are placed in a stereotaxic frame, where craniotomies are performed above the region of the medial prefrontal cortex (mPFC) and ipsilateral (CA)1/subiculum. Body temperature of the rat is maintained at 37°C with an electrical heating pad. The femoral vein is cannulated for administration of test drugs (PF-05180999, etc.). After the conclusion of the experiments animals are euthanized with an iv bolus of urethane[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.
