Synonyms: L-454,560 [1] | L-454560 | MK0359
Compound class: Synthetic organic
Comment: MK-0359 is a potent and selective, oral PDE4 inhibitor that has a competitive and reversible mode of interaction. MK-0359 is identified as L-454,560 [1] by citation in [2]. MK-0359 inhibits both the apo- (Mg2+ free) and holoenzyme ((Mg2+-bound) states of PDE4 [1].

Bioactivity Comments
MK-0359 is active in vitro and in vivo [1]. It blocks LPS-induced TNF-α formation in whole blood assays with a potency similar to that exhibited by roflumilast. Evidence suggest that majority of the anti-inflammatory effect of PDE4 inhibition is through PDE4B and PDE4D isozymes, and that PDE4D, as the major isoform in the brain responsible for emesis [3], is associated with the adverse gastrointestinal (GI) events associated with PDE4 inhibition. MK-0359 inhibits the hydrolysis of cAMP by PDE4A, 4B and 4D with similar potencies, which accounts for the adverse GI effects observed in clinical trial [2].
