PRN2246 inhibits both Fc receptor activation (IC50=166 and 9.6 nM for FcεR and FcγR) and BCR-mediated immune cell activation (IC50=10 nM) [2]. With an IC50 of 157 nM, PRN2246 targets small molecule FcγR activation via persistent port BTK [2].

| Additional Infomation |
Tolebrutinib is an orally bioavailable, brain-penetrant, selective, small molecule inhibitor of Bruton's tyrosine kinase (BTK), with potential immunomodulatory and anti-inflammatory activities. Upon oral administration, tolebrutinib is able to cross the blood-brain barrier and inhibits the activity of BTK both peripherally and in the central nervous system (CNS). This prevents the activation of the B-cell antigen receptor (BCR) signaling pathway, and the resulting immune activation and inflammation. The inhibition of BTK activity also prevents microglial inflammatory signaling in the CNS, and the resulting immune activation, neuroinflammation and neurodegeneration. BTK, a cytoplasmic tyrosine kinase and member of the Tec family of kinases, plays an important role in B lymphocyte development, activation, signaling, proliferation and survival. In addition to B cells, BTK is also expressed in innate immune cells, including macrophages and microglia, and plays an important role in the regulation of microglial inflammatory signaling.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.49 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 (5.49 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 25.0 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: ≥ 2.5 mg/mL (5.49 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.
