Hcyb1
Based on 1 Customer Validation
Hcyb1 is a highly selective, orally active PDE2 inhibitor. Hcyb1 has a highly selective inhibition of PDE2A (IC50=0.57 μM) and over 250-fold selectivity against other recombinant PDE family members. Hcyb1 produces neuroprotective and antidepressant‐like effects most likely mediated by cAMP/cGMP-CREB-BDNF signaling.

Biological Activity

PDE2 |
Hcyb1 (1~100 nM; 10 minutes) increases cGMP levels by 1.7~2.3 folds[1].
Hcyb1 (1 nM; 24 hours) increases both cGMP and cAMP levels[1].
Hcyb1 (24 hours) treatment also increases the levels of phosphorylation of CREB and BDNF in HT-22 cells[1].
Hcyb1 promotes HT-22 cell viability and increase the cGMP and cAMP accumulation in HT-22 cells[1].
Hcyb1 exhibits the concentration- and time-dependent effects on cell viability in HT-22 cells[2].

Cell Line:HT-22 cells
-
Concentration:1 pM, 0.01 nM, 0.1 nM, 1 nM, 0.01 μM, 0.1 μM, 1 μM, 10 μM
-
Incubation Time:24 hours
-
Result:The cell viability was significantly increased when treatment HT-22 cells with Hcyb1 at concentrations of 0.1 nM and 1 nM for 24 hours. The time-dependent effects showed that the cell viability was significantly increased from 12 to 24 hours when treatment at concentration of 1 nM. The maximal effects peaked at 24 hours after treatment.

Solvent & Solubility
DMSO : 62.5 mg/mL (164.28 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: ≥ 2.08 mg/mL (5.47 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
