At one and three days postinfection, tulobuterol (0.1 μM; 24 h or 72 h; human tracheal epithelial cells) therapy decreased RV14 RNA levels. Prior to RV14 infection, the supernatants of cells treated with tulobutero had a considerably lower concentration of sICAM-1 than did the cells treated with vehicle. The quantity and intensity of green-fluorescent acidic endosomes in cells were both decreased by tulobuterol treatment. also decreased the release of IL-1β, IL-6, and IL-8 brought on by RV14 infection. RV14-induced NF-κB p50, p65, and c-Rel levels were significantly but modestly reduced upon tulobuterol administration [1].

The study investigated the impact of tuloterol on the contractility of diaphragms extracted from endotoxin-treated mice (BALBs/c animals; 21.7 ± 0.2 g). With the use of force-frequency curves of untreated or treated diaphragms at 0 (E0) and 4 (E4) hours following the administration of an E. Coli endotoxin (20 mg/kg), contractile characteristics and twitch kinetics were determined. After transdermal tuloterol treatment, E0 and E4 diaphragms were examined 0, 12, and 24 hours later. The tuloterol patch restored muscular contractility, as evidenced by the force-frequency curves of the E0 and E4 diaphragms at the three time periods that did not significantly differ from one another. Thus, during the 4-hour endotoxin treatment interval, diaphragm contractility was sustained for over 24 hours with the use of the tuloterol patch [2].

RT-PCR[1]
Cell Types: Human tracheal epithelial cells infected with RV14 Tested Concentrations: 0.1 μM Incubation Duration: 24 hrs (hours) or 72 hrs (hours) Experimental Results: RV14 RNA levels diminished 1 and 3 days after infection. The concentration of sICAM-1 in the cell supernatant was Dramatically diminished. Reduce the number of intracellular green fluorescent acidic endosomes and the fluorescence intensity of intracellular acidic endosomes. The secretion of IL-1β, IL-6, and IL-8 induced by RV14 infection was also diminished. RV14 infection induced a small but significant reduction in the amounts of p50, p65, and c-Rel of NF-κB. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.98 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 (10.98 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

*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.
