Azumolene

SKU: orb1219243

Description

Azumolene1.EU4093 (azumolene sodium) is a direct acting, skeletal muscle relaxant with structural similarities to dantrolene sodium in that the para-nitro phenyl group of dantrolene sodium is replaced by a para-bromo phenyl group. 2. The effect of EU4093 on the twitch of the intact rat soleus preparation is nearly maximal at a dose of 20 mg kg-1. This dose of EU4093 reduces the amplitude of the twitch to 31.9% of the control value. By comparison, dantrolene sodium reduced the twitch amplitude to 31.3% of the control value at a dose of 5 mg kg-1. 3. The contraction of intrafusal muscle as measured by the response of spindle afferent discharge was also reduced by EU4093. 4. The most significant difference between the effect of EU4093 and dantrolene sodium on the contraction of intrafusal muscle was that EU4093 had an appreciable depressant action at high stimulation frequencies at which dantrolene sodium had only a minimal relaxant effect on the intrafusal muscle contraction.

Bioactivity

• In Vivo:
  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.
