JNJ16259685 (JNJ-16259685) is a novel, potent, selective and non-competitive antagonist of mGlu1 receptor with IC50 of 19 nM. JNJ16259685 did not alter immobility, but it did result in a notable decrease in offensive behaviors (attack and threat). In a concentration-dependent way, it prevents mGlu1 from being synaptically activated. Up to a dose of 30 mg/kg, JNJ16259685 had very little effect on hip flexion and posture. In rats, motor skill remained intact for well-learned tasks (up to 30 mg/kg), but in mice, it was impaired. The learning of a novel motor skill (rotarod) was severely hindered in both rats and mice rats (0.3 mg/kg).

| Animal Protocol |
Mice: There are nine mouse groups in use. The animals are randomized into seven experimental groups (N=14–16 each) that receive injections of JNJ16259685 and two control groups (n=15 each) that receive only saline or saline (90%) plus DMSO (10%). In order to provide suitable injection doses, JNJ16259685 is diluted in saline (90%) plus DMSO (10%) and given in seven doses: 0.125, 0.25, 0.5, 1, 2, 4, and 8 mg/kg. The dosages are selected based on the results of recent behavioral research with this substance. Ten milliliters per kilogram of drug or vehicle are injected intraperitoneally.
Rats: The overt behavioral, neurological, and autonomic reactions to the drug challenge are measured using this procedure. In summary, rats are randomly assigned to four groups (n = 6), each of which is given a different dose of JNJ16259685 (0, 3, 10, or 30 mg/kg). The animals are evaluated and scored at 30, 60, 120, and 240 minutes after injection by a skilled observer who is blind to the drugs the animals are receiving. The animals are evaluated for gait, pupil size, body elevation, limb position, limb tone, and passivity. For every behavior, animals that seemed "normal" were given a score of 0, while animals that showed mild, moderate, or severe increases (+) or decreases (−) from normalcy were given scores of ±1, ±2, or ±3. Individual animals are deemed to be significantly affected on the measure if they score ±2 or higher. If three or more of the animals receive a score greater than ±2, the dose is deemed significant. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.75 mg/mL (8.45 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.75 mg/mL (8.45 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 27.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.75 mg/mL (8.45 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
