The present invention provides an amino-imidazolone compound of formula I
Also provided are compositions and methods for the use thereof to inhibit β-secretase (BACE) and treat β-amyloid deposits and neurofibrillary tangles.
The invention relates to pyrimido 1,2-b!isoquinolines of the formula ##STR1## and their pharmaceutically acceptable acid addition salts. In the formula, R.sup.1 and R.sup.2 each represent hydrogen, hydroxyl, lower alkyl, lower alkoxy, trifluoromethyl, halogen, amino or mono- or di-(lower)alkylamino and R.sup.3 and R.sup.4 each represent hydrogen or lower alkyl. The compounds have utility as anti-gastric ulcer agents.

of small molecule aminoimidazoles as potent and selective humanβ-secretaseinhibitors is reported. These analogues demonstrate low nannomolar potency for BACE1 in a FRET assay, exhibit comparable activity in a cell-based (ELISA) assay, and show >100× selectivity for the other structurally related aspartyl proteases BACE2, cathepsin D, renin, and pepsin.
