KC-11404
KC-11404 is an orally active antihistamine and 5-lipoxygenase inhibitor, with an IC50 of 0.9 μM against guinea pig 5-lipoxygenase. KC-11404 inhibits histamine-induced contraction of isolated guinea pig ileum with an IC50 of 0.26 μM. KC-11404 inhibits PAF-induced rabbit platelet aggregation with an IC50 of 2.0 μM. It inhibits the histamine phase of antigen-induced bronchoconstriction and PAF-induced bronchoconstriction in guinea pigs. KC-11404 can be used for the research of asthma.

5-LOX 0.9 μM (IC50) |
KC-11404 potently inhibits histamine-induced contractions of isolated guinea pig ileum with an IC50 of 0.26 μM[1].
KC-11404 inhibits PAF-induced aggregation of rabbit platelets with an IC50 of 2.0 μM[1].
KC-11404 (10 μM) completely inhibits semipurified guinea pig PMN 5-lipoxygenase with an IC50 of 0.9 μM[1].

KC-11404 (oral administration; single dose) potently inhibits passive cutaneous anaphylaxis in rats, with an ED50 of 0.9 μmol/kg[1].
KC-11404 (oral administration; single dose) inhibits the histamine phase of antigen-induced bronchoconstriction in guinea pigs, with an ED50 of 1.9 μmol/kg[1].
KC-11404 (oral administration; single dose) inhibits PAF-induced bronchoconstriction in guinea pigs, with an ED50 of 2.1 μmol/kg[1].
KC-11404 (50 μmol/kg; p.o.; single administration) exhibits efficacy comparable to that of Zileuton (HY-14164) in inhibiting the leukotriene-dependent phase of antigen-induced bronchoconstriction in guinea pigs at a dose of 50 μmol/kg[1].
