NGD94-1
Based on 1 Customer Validation
NGD94-1 is a potent and selective dopamine D4 receptor antagonist. NGD94-1 shows high affinity for the cloned human D4.2 receptor (Ki = 3.6 nM). NGD94-1 modulates the cognitive functions of the frontostriatal system and regulates dopaminergic transmission in Phencyclidine (PCP)-induced monkeys. NGD94-1 can be used for neurological disease research[1][2].

hD4.2 Receptor 3.6 nM (Ki) |
NGD 94-1 shows >600-fold selectivity for the D4.2 receptor over many other targets; however, its selectivity is significantly lower over the 5-HT1A (~50-fold) and 5-HT3 (~200-fold) receptors[2].
NGD 94-1 induces inhibition of cAMP accumulation in HEK293/D4 cells, but does not affect Forskolin (HY-15371)-stimulated cAMP formation in non-transfected HEK293 cells, demonstrating that its inhibitory action is specifically mediated through the transfected dopamine D4 receptors[3].

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 (7.80 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.80 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.
