Enpatoran (M-5049) is a novel and selective inhibitor of Toll-Like Receptor 7/8 with IC50 of 11.1 and 24 nM, respectively. No activity against TLR3, TLR4, and TLR9. It has the potential to be used for the treatment of autoimmune diseases.
| ln Vitro |
Enpatoran (0.01 nM–10 μM) has IC50 values between 35 and 45 nM and suppresses the production of IL-6 induced by all ligands (miR–122, Let7c RNA, Alu RNA, and R848)[1].

| ln Vivo |
In a ligation-dependent manner, epatoran (M5049; gavage; 1 mg/kg) delivered prior to R848 (25 μg intraperitoneally) kills mice via inhibiting the generation of IL-6 and IFN-α [1]. showed excellent bioavailability following one draft (1.0 mg/kg for TB, TB, and dogs; 100% for TB, 87% for TB, and 84% for dogs) [1]. Higher braid clearance rates (1.4, 1.2, and 0.59 L/h/kg, respectively) and larger animals (2.7, 8.7, and 5.7 L/kg, respectively) were seen in structural and canine 1.0 mg/kg; iv) cases.

| Animal Protocol |
Animal/Disease Models: Female C57BL/6 mice[1]
Doses: 0.1 mg/kg and 1 mg/kg Route of Administration: po (oral gavage); moderate half-life (mouse 1.4, stability 5.0 and dog 13 hrs (hrs (hours)))[1 ]. Results of R848 administration 1 hour before challenge: TLR7/8 agonist R848 stimulated the production of IFN-α and IL-6 in mice. Enpatoran reduces R848-stimulated IFN-α and IL-6 production. Animal/Disease Models: female CD1 mice, female Wistar rats, female beagle dogs [1] Doses: 1 mg/kg (pharmacokinetic/PK/PK analysis) Route of Administration: intravenous (iv) (iv)(iv) or po (oral gavage) Experimental Results:Mouse T1 /2 are 1.4, 5.0 and 13 h for mice and dogs respectively. |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.44 mg/mL (7.62 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 24.4 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: ≥ 2.44 mg/mL (7.62 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 24.4 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. (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.
