THIQ is a novel and potent agonist of the melanocortin-4 receptor (MC4R) with high activity for hMC4R (IC50=1.2 nM, EC50=2.1 nM) and rMC4R (IC50=0.6 nM, EC50=2.9 nM).
| ln Vitro |
THIQ has poor potency against the human MC1R, MC3R, and MC5R, with IC50s of 2067, 761, and 326 nM and EC50s of 2850, 2487, and 737 nM, respectively. THIQ has poor potency in rat MC3R and MC5R, with IC50s of 1883 and 1575 nM, and EC50s of 1325 and >3000 nM [1]. THIQ (10 μM; 24 hours) reduces the signal intensity of WT MC4R by about 50%, while boosting the signal intensity of three mutants (N62S, C84R, and C271Y) in HEK293 cells [2].

| ln Vivo |
In sexually mature male Sprague Dawley rats, THIQ (0.3-10 mg/kg; iv) dose-dependently induces erections (ED50=0.87 mg/kg). At 5 mg/kg, there was the greatest rise in erections (60%) but there was no discernible difference between that and 1 mg/kg. With an average rise of 31±4%, THIQ (20 mg/kg; oral) also considerably improves erectile response [1]. When given at 1 mg/kg IV and 10 mg/kg PO, THIQ therapy in Sprague-Dawley rats resulted in a t1/2 of 0.6 hours [1].

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.53 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 20.8 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: ≥ 2.08 mg/mL (3.53 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 20.8 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.
