Alzheimer’s disease (AD) is basically associated with disturbances of cholinesterase metabolism which result in acetylcholine deficiency. Target of acetylcholinesterase (AChE) inhibitors used in symptomatic therapy of disease is to increase of ACh levels. Consequently, cholinesterase inhibitors were developed to increase acetylcholine is to inhibit AChE and butrylcholinesterase (BuChE). Studies demonstrate the clinical importance of dual inhibitors that inhibit not only the acetylcholinesterase enzyme but also the butyrylcholinesterase enzyme.

With excess oxidant, oxidation also occurs in the benzene ring at C5. Benzoxazole is much more reactive and gives a variety of products formed by oxidation of both rings. Benzothiazole is the least reactive system and suffers only minimal oxidation at C2 of the thiazole ring.
