Ibudilast is a relatively nonselective phosphodiesterase inhibitor which has been marketed for almost 20 years in Japan for treating asthma. More recently it has been found to have anti-inflammatory activity in both the peripheral immune system and in the CNS

Neuroinflammation induced by activated microglia and astrocytes can be elicited by drugs of abuse. Methamphetamine administration activates glial cells and increases proinflammatory cytokine production, and there is recent evidence of a linkage between glial cell activation and drug abuse-related behavior.

Questions

  1. Hello! I need to know whether I can prepare the working solution of the Ibudilast powder by diluting it in DMSO and freezing for storage at -20C. Will the compound be not degraded or damaged after freezing?

    1 answer
    1. This product is soluble in DMSO at 28 mg/mL. The recommended storage temperature is 2-8°C
      Please see the product data sheet for more information:
      https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/268/374/i0157dat.pdf

      However, solutions in DMSO or ethanol may be stored at -20°C for up to 3 months. The end-user will need to be cautious about keeping the product at -20°C for long-term storage and determine the stability at such temperatures empirically as this is not tested internally.
