THIQ is the first selective agonist of the melanocortin-4 receptor (MC4R), with high affinity and potency for hMC4R (IC₅₀=1.2 nM, EC₅₀=2.1 nM) and rMC4R (IC₅₀=0.6 nM, EC₅₀=2.9 nM). THIQ maintains low potency at MC1R, MC3R and MC5R. THIQ plays a role in eliciting erectile activity in rodents. THIQ acts as a pharmacoperone of the MC4R rescuing the cell surface expression and signaling of some intracellularly retained MC4R mutants.

In Vitro

THIQ maintains low potency at human MC1R, MC3R and MC5R with IC₅₀s of 2067, 761, 326 nM and EC₅₀s of 2850, 2487, 737 nM, resepectively. THIQ maintains low potency at rat MC3R and MC5R with IC₅₀s 1883 and 1575 nM, and EC₅₀s of 1325 and >3000 nM, respectively^[1].
? THIQ (10 μM; 24 hours) decreases the signal intensity of WT MC4R by approximately 50% whereas increases that of three mutants (N62S, C84R, and C271Y) in HEK293 cells^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

THIQ (0.3-10 mg/kg; i.v.) dose-dependently increases erections (ED₅₀=0.87 mg/kg) in sexually mature male Sprague Dawley rats. The maximal increase in the number of erections (60%) is detected at 5 mg/kg but was not significantly different from that produced by 1 mg/kg. THIQ (20 mg/kg; p.o.) also produces statistically significant increases in erectile responses with a mean increase of 31±4%^[1].
? THIQ treatment shows the t_1/2 is 0.6 hours in Sprague-Dawley rats (1 mg/kg, i.v. and 10 mg/kg, p.o.)^[1].

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (4.24 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.08 mg/mL (3.53 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
