Darbufelone mesylate (CI-1004 mesylate) is a dual inhibitor of cellular PGF2α and LTB4 production. Darbufelone potently inhibits PGHS-2 (IC50 = 0.19 μM) but is much less potent with PGHS-1 (IC50= 20 μM).
R112 is a Syk inhibitor. R112 inhibited degranulation induced by anti-IgE cross-linking in mast cells and also blocked leukotriene C4 production and all proinflammatory cytokines tested.
Atreleuton (ABT-761) is a selective, reversible, and orally bioavailable 5-Lipoxygenase (5-LO) inhibitor. Atreleuton (ABT-761) exhibits potent and selective inhibition of leukotriene formation.
AZD9898 is an orally active leukotriene-C4 synthetase (LTC4S, glutathione S-transferase II) inhibitor, with an IC50 of 0.28 nM. AZD9898 mitigates the GABA binding and hepatic toxicity signal. AZD9898 has the potential to treat asthma.
