Product Description
Tulobuterol HCl (C-78) is a long-acting β2-adrenoceptor agonist that reduces the frequency of chronic obstructive pulmonary disease and bronchial asthma. Tulobuterol HCl is also a sympathomimetic agent used as a transdermal patch to increase normal diaphragm muscle strength. Tulobuterol HCl inhibits rhinovirus replication and modulates airway inflammation.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
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. Both the quantity and intensity of green fluorescence shown by acidic endosomes in cells were diminished during 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].
ln Vivo
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. Consequently, during the 4-hour endotoxin delivery interval using the tuloterol patch, diaphragm contractility was maintained for longer than 24 hours [3].
Cell Assay
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.

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.

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.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
