Inhibition of acetylcholinesterase has successfully been used as a drug target to treat Alzheimer s disease but drug resistance shown by butyrylcholinesterase remains a matter of concern in treating Alzheimer s disease. Apart from the many other reasons for Alzheimer s disease its association with the genesis of fibrils by p-amyloid plaques is closely related to the increased activity of butyrylcholinesterase. Although few data are available on the inhibition of butyrylcholinesterase studies have shown that that butyrylcholinesterase is a genetically validated drug target and its selective inhibition reduces the formation of p-amyloid plaques. Rationale We previously reported the inhibition of cholinesterases by 2 3-dihydro-1 5-benzothiazepines and considered this class of compounds as promising inhibitors for the cure of Alzheimer s disease. One compound from the same series when substituted with a hydroxy group at C-3 in ring A and 2-thienyl moiety as ring B showed greater activity against butyrylcholinesterase than to acetylcholinesterase. To provide insight into the binding mode of this compound Compound A molecular .
