IBMX (3-isobutyl-1-methylxanthine), like other methylxanthine derivatives, is both a:

  1. competitive non-selective phosphodiesterase inhibitor [1] which raises intracellular cAMP, activates PKA, inhibits TNFα [2] [3] and leukotriene [4] synthesis, and reduces inflammation and innate immunity, [4] and
  2. nonselective adenosine receptor antagonist. [5]

As a phosphodiesterase inhibitor, IBMX has IC50 = 2–50 μM [6] and does not inhibit PDE8 or PDE9. [7]
