Biological Activity

Tulobuterol is a long-acting and selective agonist of the β2-adrenoceptor. Activation of β2-adrenoceptor signaling stimulates downstream cyclic AMP pathways, leading to the relaxation of airway smooth muscle tissue and an increase in normal diaphragm muscle strength. Consequently, tulobuterol aids in the treatment of bronchial asthma and provides cellular protection against endotoxins present in inhaled house dust.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
