KVA-D-88
Based on 1 Customer Validation
KVA-D-88 is a blood-brain barrier-permeable PDE4 inhibitor with IC50 values of 140 and 880 nM for PDE4B and PDE4D, respectively. KVA-D-88 induces cAMP accumulation and inhibits neuroactive substance-mediated hyperlocomotion, locomotor sensitization. KVA-D-88 can be used for the research of drug addiction.

Biological Activity
|
PDE4B 140 nM (IC50) |
PDE4D 880 nM (IC50) |
KVA-D-88 preferentially inhibits the PDE4B isoform over PDE4D in vitro, with an IC50 of 140 nM for PDE4B and 880 nM for PDE4D[1].
KVA-D-88 (1-100000 nM; overnight) induces cAMP accumulation in PDE4B1-transfected HEK293 cells with an EC50 of 0.5 μM in vitro[1].

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.

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.
