SM-324405 (SM324405; SM 324405) is a novel and potent TLR7 (toll-like receptor 7) agonist designed by introducing the antedrug concept with reduced systemic activity. Toll-like receptor 7 (TLR7) agonists have potential in the treatment of allergic diseases. However, the therapeutic utility of current low molecular weight TLR7 agonists is limited by their systemic activity, resulting in unwanted side effects.
| ln Vitro |
SM-324405 is a novel therapeutic candidate intended for use in allergy immunotherapy [1].

|---|---|
| ln Vivo |
SM-324405 (9e, intratracheal administration) efficiently prevents systemic cytokines from being released while suppressing allergen-induced airway inflammation [1]. With a half-life of 2.6 minutes, SM-324405 is converted to the corresponding acid in human plasma [1][2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.49 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution.
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.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.5946 mL | 12.9729 mL | 25.9457 mL | |
| 5 mM | 0.5189 mL | 2.5946 mL | 5.1891 mL | |
| 10 mM | 0.2595 mL | 1.2973 mL | 2.5946 mL |
*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.
