Pretreatment with 20 μM Azumolene for 1-2 min inhibits SOCE activated by subsequent addition of caffeine and ryanodine to promote RyR-dependent sarcoplasmic reticulum Ca ²⁺ store depletion in mouse myotubes and adult muscle fibers.

The effect of Azumolene (EU4093) on the twitch of the intact rat soleus preparation is nearly maximal at a dose of 20 mg/kg. This dose of Azumolene reduces the amplitude of the twitch to 31.9% of the control value. The contraction of intrafusal muscle as measured by the response of spindle afferent discharge is also reduced by Azumolene.
