PH-064 (BIM-46187) is an orally active inhibitor of the heterotrimeric G-protein complex. PH-064 inhibits SERT activity and attenuates shear stress-induced Akt phosphorylation. PH-064 has potent anti-hyperalgesia activity. PH-064 inhibits G protein-coupled receptor-dependent tumorigenesis. PH-064 can be used in the study of pain (e.g., inflammatory pain, neuropathic pain), GPCR-dependent tumors, and inflammatory lung injury.

In Vitro

PH-064 (20 μM; 1 h) abrogates the flow-induced dissociation of Gαq/11 from PECAM-1 in HCAECs and attenuates shear stress-induced Akt phosphorylation[2].
PH-064 (10 μM-100 μM; 30 min) concentration-dependently inhibits SERT-mediated 5HT uptake in mouse midbrain and frontal cortex synaptosomes, and also inhibits SERT activity in TRex-SERT cells[3].
PH-064 (for basal IP: even at 10-4 M) has no inhibitory effect on basal IP production in E151A-CCK2R-transfected COS cells, but completely inhibits Gastrin-stimulated IP production (EC50: 34 μM)[5].
PH-064 (10 μM; 1 h) reduces IFNγ generation in RGS2 null BMDMs to the level of WT-BMDMs without affecting BMDM viability[6].

In Vivo

PH-064 (0.1-1 mg/kg; i.v.) elicits dose-dependent anti-hyperalgesic effect in Carrageenan (HY-125474)-induced hyperalgesia model in rats, without affecting paw oedema and motor performance[1].
PH-064 (0.3-3 mg/kg; i.v.) shows dose-dependent anti-hyperalgesic effect in chronic constriction injury (CCI) model in rats[1].
PH-064 (75 mg/kg; p.o.; twice a day; 16 days) exhibits antitumor activity in athymic nude mouse xenografts with E151A-CCK2R-NIH-3T3 cells without apparent toxicity[5].
PH-064 (3 mg/kg; i.v.; 2 h after i.t. LPS) reduces IFNγ expression by 80% in RGS2 null mouse lungs and promotes resolution of lung edema[6].

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 (3.14 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 (3.14 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.
