Popis: A series of trisubstituted benzenes which demonstrate leukotriene B 4 (LTB 4 , 1 ) receptor affinity was prepared. Previous trisubstituted benzenes from our laboratory showed high affinity to the LTB 4 receptor but demonstrated agonist activity in functional assays. Compound 3a , the initial lead compound of this new series, showed only modest affinity (IC 50 = 0.20 μM). However, 3a was a receptor antagonist with no demonstrable agonist activity up to 30 μM. Further modification of the lipid tail and aryl head groups region led to the discovery of 3b (ONO-4057). This compound, free of agonist activity, possesses high affinity to the LTB 4 receptor ( K i = 3.7±0.9 nM).
