6(R)-(4-CARBOXYPHENYLTHIO)-5(S)-HYDROXY-7(E),9(E),11(Z),14(Z)-EICOSATETRAENOIC ACID Usage And Synthesis

Uses

BAYu9773 is a dual non-selective, CysLT1 and CysLT2 receptor antagonist, having about the same IC50 (20-80 nM) for the inhibition of LT responses in a variety of tissue preparations containing either/or both receptors.

Definition

ChEBI: BAYu9773 is a dicarboxylic acid that is that is (7E,9E,11Z,14Z)-icosa-7,9,11,14-tetraenoic acid substituted by a hydroxy group at position 4S and a (4-carboxyphenyl)sulfanediyl group at 5R. It is a dual cysteinyl leukotriene receptor antagonist that acts at the CysLT1 and CysLT2 receptors (IC50 = 0.44 and 0.30 muM, respectively). It has a role as a leukotriene antagonist. It is a dicarboxylic acid, a secondary alcohol, an organic sulfide, a member of benzoic acids and a polyunsaturated fatty acid. It is functionally related to an icosa-7,9,11,14-tetraenoic acid.

Biological Activity

Cysteinyl leukotriene receptor antagonist with equal affinity at both CysLT 1 and CysLT 2 receptors (pK B values are 6.8 and 6.5 respectively). Competitive antagonist of LTC 4 - and LTE 4 -induced contractions of the guinea pig trachea.
