IBMX

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]
