  phenylalanine with a cyclohexyl group greatly enhance potency. Several ester bioisosteres that retain potency and enantiomeric selectivity are described. Lead optimization culminated in (S)-N-[2-cyclohexyl-1-(2-pyridinyl)ethyl]-5-methyl-2-benzoxazolamine+ ++ (43b), IC50 0.001 microM. The compounds described are not inhibitors of 5-lipoxygenase but, rather, act at the level of arachidonic acid release.
