toxicological effect in the form of peroxisomal proliferation was performed in order to achieve the target compound OT4003. OT4003 ((S)-(+)-E-2-(3-(2-(7- chloroquinolin-2-yl)ethenyl)phenylaminomethyl)-phenoxyl++ +-hexanoic acid) was found to be a potent and selective inhibitor of [3H]LTD4 specific binding to guinea pig lung membranes (IC50 2.4 +/- 1.0 nM), and also a potent, orally active, antagonist of LTD4 induced
