A deficit of cholinergic neurotransmission is considered to be one of the major causes of disturbance in learning and memory. Among the various therapeutic approaches investigated to enhance cholinergic transmission, acetylcholinesterase (AChE) inhibition is presently the most successful method to ameliorate cholinergic deficit. Keeping in view the activity of numerous quinoline derivatives reported as potential cognitive enhancers attempts were made to design and synthesize some 6-aminoquinoline derivatives. The title compounds were synthesized via an intermediate 6-nitroquinoline which was...
