  • Experimental Physico-chemical Properties
  • Miscellaneous
    • Chemical Class:

      2,2-Diethylsuccinanilic acid substituted at a <ital>meta</ital>- position by an (<stereo>E</stereo>)-2-(4-cyclobutyl-1,3-thiazol-2-yl)ethenyl group. It selectively antagonizes leukotriene D<smallsub>4 </smallsub> at the cysteinyl leukotriene receptor, in the human airway, preventing airway edema, smooth muscle contraction, and enhanced secretion of thick, viscous mucus. It is used in the treatment of asthma. ChEBI CHEBI:126598
