TMC353121 shown effectiveness against a panel of clinical isolates with comparable potency as well as group A and group B RSV [1]. A strong in vitro RSV fusion inhibitor is TMC353121. In HeLaM cells, TMC353121 exhibits 50% effective concentration (EC50) of 0.07 ng/mL against wild-type RSV (LO strain) [2].

| ln Vivo |
After giving Sprague-Dawley rats a single intravenous bolus dosage of 10 mg/kg, TMC353121's plasma concentration-time profile showed multicompartmental pharmacokinetics. The final part of the curve, which shows the mean plasma drug concentrations between 8 and 24 hours after dose, shows that the drug concentrations decrease quickly in the first few hours after dosing and then more slowly, with a half-life of about 12 hours. With a clearance rate of 8.6 L/h/kg and a distribution width of 55 L/kg, TMC353121 is rapidly removed from plasma [2]. Two injections of TMC353121, at a dose of 2.5 mg/kg or 0.25 mg/kg, are given intravenously once. Serum, bronchoalveolar lavage fluid, and lung tissue drug concentrations were assessed at various times. When administered intravenously, TMC353121 exhibits multicompartmental pharmacokinetics, meaning that its serum concentration rapidly decreases within the first hour and then slowly declines over the next hour. After a day, the drug's blood levels are extremely low due to its rapid excretion from the body. The drug was marginally above the detection limit in BAL fluid eight hours after injection, and pulmonary concentrations were significantly greater than serum concentrations.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.47 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 (4.47 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. 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 (4.47 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.
