Compounds of formula I: are potent and selective inhibitors of microtubule affinity regulating kinase (MARK), and hence find use in treatment of Alzheimer's disease and other conditions associated with hyperphosphorylation of tau.

The chemical stability and reactivity of hydroxy-1-aminoindans and their N-propargyl derivatives are strongly affected by the position of the OH group and its orientation relative to that of the amino moiety. Thus, the 4- and 6-OH regioisomers were found to be stable, while the 5-OH analogues were found to be inherently unstable as the free bases. The latter, having a para orientation between the OH and the amino moieties, could be isolated only as their hydrochloride salts. 7-Hydroxy-1-aminoindans and 7-hydroxy-1- propargylaminoindans represent an intermediate case; while sufficiently stable even as free bases, they exhibit, under certain experimental conditions, unexpected reactivity. The instability of the 5- and 7-hydroxy-aminoindans is attributed to their facile conversion to the corresponding, reactive quinone methide (QM) intermediates. The o-QM obtained from 7-hydroxy-aminoindans was successfully trapped with ethyl vinyl ether via a Diels-Alder reaction to give tricyclic acetals 32a,b.

To developed a novel cerebroprotective agent with central nervous system (CNS) stimulating activity, a series of 1-amino-7-hydroxyindan derivatives was synthesized, and their effects on the survival time of mice under hypoxic conditions were tested.CNS-stimulating activity was also evaluated by examining the promotional effect on the recovery from cerebral concussion induced coma in mice.Several compounds prolonged the survival time of mice in hypoxic conditions at a dose of 30 mg/kg (sc or ip) and 100 mg/kg (po).They also exhibited the promotional effects on recovery from coma at a dose of 100 mg/kg po.The three most potent compounds in both tests, 1-amino-7-hydroxy-6-(1-methylpropyl)indan (20), 1-amino-7-hydroxy-4,6-dimethyl-2-phenylindan (30), and 1-amino-7-hydroxy,2,2,4,6-tetramethylindan (35) were selected for further investigations.Structure-activity relationships were also discussed.
