Compounds having the formula (I)
pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid β protein production and neurological disorders such as Alzheimer's disease.. These compounds inhibit γ secretase and thereby inhibit the production of amyloid P protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.
The invention relates to a prodrug that is capable of being converted into a drug by the catalytic action of human fibroblast activation protein (FAP&agr;), said prodrug is chemically stable under physiological conditions and can be used for the manufacture of physically stable aqueous formulations. It has a cleavage site which is recognised by FAP&agr;, and the drug released by the enzymatic activity of FAP&agr; is cytotoxic or cytostatic under physiological conditions.
