A triptycene-based bis(benzoxazole) diacid ligand H2L2 Ph4 bearing sterically encumbering groups was synthesized. Treatment of H2L2Ph4 with Fe(OTf)3 afforded a C 2-symmetric trinuclear iron

Novel 4,5-, 4,6-disubstituted and 4,5,6-trisubstituted 3- hydroxyanthranilic acid derivatives were synthesized and their ability to reduce the production of the excitotoxin quinolinic acid (QUIN) by inhibition of brain 3-hydroxyanthranilic acid dioxygenase (3-HAO) was subsequently investigated. The potency of the compounds to inhibit 3-HAO was assayed in rat brain homogenate, while chemical stability of certain compounds was studied by HPLC. The data were used to generate quantitative structure- activity relationship (QSAR) models for potency of 3-HAO inhibition and compound stability. Compounds with longer half-lives were obtained when the difference between the HOMO and LUMO was increased, while electron withdrawing groups in the 4- and 5-positions increased the potency of 3-HAO inhibition. Selected compounds that showed high potency in vitro were also found to be efficacious inhibitors in vivo after cerebral administration in rats.
