PF-CBP1 hydrochloride is a highly selective inhibitor of the CREB binding protein bromodomain (CBP BRD). PF-CBP1 inhibits CREBBP and EP300 bromodomains with IC₅₀ of 125 nM and 363 nM respectively. PF-CBP1 hydrochloride reduces LPS-induced inflammatory cytokines expression (IL-1β, IL-6 and IFN-β) in primary macrophages. PF-CBP1 hydrochloride also downregulates RGS4 expression cortical neurons and can be used for the research of neurological disorders, including epilepsy and parkinson's disease, et al.

In Vitro

ITC is the label-free technique for determining K_D values, PF-CBP1 is against CBP (K_d=0.19 μM) and >105-fold selective over BRD4 (K_d>20 μM) by ITC^[1].
PF-CBP1 displays greater than 100-fold selectivity for the bromodomain of CBP over those of BRD4 and a panel of other proteins, it against BRD2-1,BRD3-1, BRD3-2,BRD4-1, BRD4-2, BRDT-1, TAF1-2, and TAF1L-2 with IC₅₀ values of 1.24 μM, 1.38 μM, 4.22 μM, 1.54 μM, 9.75 μM, 2.44 μM, 3.39 μM and 7.29 μM, respectively^[1].
PF-CBP1 (3-10 μM; pretreatment 30 mins; 4 hours) moderately reduces LPS-induced IL-6 and IFN-b expression in the J774 cell at 10 μM. And it decreases IL-1b expression evidently at 3 μM^[1].
PF-CBP1 (100 nM-1000 nM;24 hours) significantly reduced RGS4 mRNA levels(49% reduction) relative to vehicle in cortical neuron cells^[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 (4.76 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 (4.76 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (4.76 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
