Imatinib mesylate, 1a, inhibits production of β-amyloid (Aβ) peptides both in cells and in animalmodels. It reduces both the β-secretase and γ-secretase cleavages of the amyloid precursor protein (APP) and mediates a synergistic effect, when combined with a β-secretaseinhibitor, BACE IV. Toward developing more potent brain-permeable leads, we have synthesized and evaluated over 75 1a-analogues. Several
