PF-07208254
Based on 1 Customer Validation
PF-07208254 is a selective, orally active allosteric inhibitor of branched-chain ketoacid dehydrogenase kinase (BDK) (IC50=110 nM, Ki=54 nM, KD=84 nM). PF-07208254 inhibits BDK-mediated BCKDH phosphorylation and enhances the catabolism of branched-chain amino acids (BCAAs) and branched-chain keto acids (BCKAs) by binding to the allosteric pocket of BDK, reducing BDK binding to BCKDH-E2 and promoting BDK degradation. PF-07208254 inhibits BDK activity in human skeletal muscle cells (IC50=540 nM) and has activity to improve cardiac function and metabolism. PF-07208254 can be used in the study of cardiometabolic diseases (e.g., heart failure, type 2 diabetes).

Animal Model:16-week-old male C57BL6/J mice, high-fat diet (HFD)-induced obese model[1]
-
Dosage:30 mg/kg, 90 mg/kg
-
Administration:Oral gavage, once daily, 8 weeks
-
Result:Reduced glucose excursion in oral glucose tolerance test (oGTT) at day 2 and week 2, with significant reduction in AUC; decreased triglyceride content in liver (with a strong trend, p=0.06) and reduced steatosis score; lowered expression of inflammatory genes (Ccl2, Ccr2, Cd68) and fibrotic genes (Col1a1, Col1a2) in liver; decreased fasting insulin levels; caused significant, dose- and time-dependent reductions in BCAA and BCKA levels in plasma and muscle.

Solvent & Solubility
DMSO : 100 mg/mL (422.53 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (10.56 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 2.5 mg/mL.
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.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
