FITM slides into the long, narrow pocket with precision. Most of the ligand-receptor interactions are hydrophobic with the exception of the contacts of the pyrimidine-amine group with the T815 7.38 side chain. The mGlu1 binding pocket for FITM largely corresponds to mutagenic data for the common allosteric site in mGlus and likely extends to other class C GPCRs. FITM, which exhibits superior selectivity and affinity for mGlu1 over mGlu5[1]. During molecular dynamics simulations, FITM has a high hydrogen bond occupancy with Tyr805 and Thr815 in dimers A and B of mGlu1. Dynamic hydrogen bonds are formed by the nitrogen and hydrogen atoms of FITM with the oxygen and hydrogen atoms of Thr815 and Tyr805, respectively. It suggests that FITM and allosteric sites interact strongly through attraction[2].

The input function is unaffected by the pretreatment of rats with unlabeled FITM (1 mg/kg), which occupies more than 99% of the mGluR1 binding site of 18F-FITM. The Kd (nM) and Bmax (pmol/mL) obtained by the Scatchard analyses with the multidose ligand assays are 2.1 and 36.3, respectively, for the thalamus; 2.1 and 27.5, respectively, for the hippocampus; 1.5 and 22.2, respectively, for the striatum; and 1.5 and 20.5, respectively, for the cingulate cortex with a high confidence[3]. 18F-FITM shows excellent pharmacokinetics, namely the dense and specific accumulation in mGlu1-positive melanomas versus mGlu1-negative hepatoma and normal tissues. In addition, levels of mGlu1 protein expression in melanomas and melanoma metastases were correlated with the accumulation levels of radioactivity[4].

| Animal Protocol |
Rats: Different doses of unlabeled FITM (0, 1, 5, or 30 μg/kg or 1 mg/kg) are administered to Sprague-Dawley rats prior to a bolus injection of 18F-FITM (17–18 MBq, 30–40 pmol, 0.1 mL). Acquired were estimates of the equilibrium state and BPND [3].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.73 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 25.0 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: ≥ 2.5 mg/mL (6.73 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
