Product Description
NGD 94-1 (dimaleate) is a potent and selective dopamine D4 receptor antagonist. NGD 94-1 (dimaleate) has a high affinity for the human D4.2 receptor (Ki = 3.6 nM). In a Phencyclidine (PCP)-induced monkey model, NGD 94-1 (dimaleate) modulates cognitive function of the prefrontal-striatal system and regulates dopaminergic neurotransmission. NGD 94-1 (dimaleate) can be used for research on neurological diseases [1][2].
Biological Activity I Assay Protocols (From Reference)
ln Vitro
NGD 94-1 (dimaleate) showed more than 600-fold higher selectivity for the D4.2 receptor than for many other targets, but its selectivity for the 5-HT1A receptor (about 50-fold lower selectivity) and the 5-HT3 receptor (about 200-fold lower selectivity) was significantly lower[2]. NGD 94-1 (dimaleate) can induce the inhibition of cAMP accumulation in HEK293/D4 cells, but does not affect Forskolin-stimulated cAMP production in untransfected HEK293 cells, indicating that its inhibitory effect is specifically mediated by the transfected dopamine D4 receptor[3].
ln Vivo
NGD 94-1 (1-5 mg/kg, surgical injection, 45 minutes before testing) (dimaleic acid) reversed PCP to repair cognitive deficits in monkeys and increased HVA accumulation in cerebrospinal fluid in the cisterns [1].
Animal Protocol
Animal/Disease Models: Young-adult vervet (Cercopithecus aethiops sabaeus) monkeys[1]
Doses: 1 and 5 mg/kg
Route of Administration: i.m., 45 min prior to testing
Experimental Results: Significantly reversed the impaired successful performance of PCP-treated subjects (from 58% to 79% accuracy) at 1 mg/kg. Ameliorated the PCP-induced impairments (from 73% to 86% accuracy) at 5 mg/kg. Reduced barrier reaching and perseverative responding at both doses in PCP-treated monkeys. Unaffected response initiation latencies and motor problems in PCP-treated monkeys. Unaffected accurate performance at 1 mg/kg in saline pretreated monkeys. Slightly impaired successful performance at 5 mg/kg in saline pretreated monkeys. Failed to affect response initiation latencies or motor problems at both doses in saline pretreated monkeys. Failed to affect HVA levels relative to saline in control subjects. Significantly increased HVA concentrations in the CSF in PCP-treated subjects.

Solubility (In Vivo)
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 1.8098 mL 9.0491 mL 18.0982 mL
5 mM 0.3620 mL 1.8098 mL 3.6196 mL
10 mM 0.1810 mL 0.9049 mL 1.8098 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
