Abstract

Background: In this study, benzothiazole-piperazine compounds were synthesized by condensing the functional groups of donepezil (DNP), FK-960, and sabeluzole, which are known to have therapeutic potential against Alzheimer's disease, with the aim of obtaining new and potent anti-Alzheimer agents.

Methods: Initially, acetylcholinesterase/butyrylcholinesterase enzyme inhibition activities of the synthesized test compounds were investigated by Ellman's method. Effects of the compounds on a streptozotocin (STZ) model of Alzheimer's disease (SMAD) were investigated in rats. SMAD was established by intracerebroventricular (icv) injection of STZ (3 mg/kg), bilaterally. The elevated plus maze, Morris water maze, and active avoidance tests were used to examine the effects of test compounds (1, 5, and 10 mg/kg) on learning and memory parameters of icv STZ-injected rats. Effects of the test compounds on spontaneous locomotor activities of rats were examined with the activity cage test.

Results: The compounds B2-B5 and DNP exhibited significant selective inhibitory potencies against acetylcholinesterase. Compounds B2 and B3 at 10 mg/kg doses and compounds B4 and B5 at 5 and 10 mg/kg doses, as well as the reference drug DNP (1 and 3 mg/kg), significantly improved the learning and memory parameters of animals in all cognition tests. None of the test compounds changed spontaneous locomotor activities.

Conclusion: Results of the present study revealed that compounds B2-B5 repaired the parameters related to the learning and memory deficits of icv STZ-injected rats. Potencies of these test compounds were comparable to the activity of DNP.
