Structural analogues of leukotriene B4 (LTB4) were designed based on the plausible conformation of LTB4 (1). Joining C-7–C-9 of the conformer A or B into an aromatic ring system led to the discovery of benzene analogues 2, 4 and 6a. Joining C-4–C-9 of the conformer C or D into an aromatic ring system led to the discovery of analogues 3, 5 and 7. The compounds examined in this study were evaluated as to their inhibition of [3H] LTB4 ...
