IBMX, 3-isobutyl-1-methylxanthine, like other methylated xanthine derivatives, is both a

1. competitive nonselective phosphodiesterase inhibitor ^[1] which raises intracellular cAMP, activates PKA, inhibits TNF-alpha ^[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]
