Some 23 analogues of the potent acetylcholinesterase (AChE) inhibitor territrem B (1) were designed, synthesized, and tested for their biological activities.
The two N-atoms of the piperazine moieties in 5o, 5p, and 5r might further enhance the inhibitory effects.

The effect of chronic (14 days) administration of the serotonin 5-HT (1A) receptors agonist 8-OH-DPAT (0.05 mg/kg, s.c.) and the 5-HT (1A) receptors antagonist NAN-190 (0.1 mg/kg, i.p.) alone or in combination with the acetylcholinesterase inhibitor galantamine (1.0 mg/kg, i.p.) on depression and anxiety was studied in old (24 months) male rats with dementia of Alzheimer's type.

J Pharmacol Exp Ther. 2004 Oct;311(1):190-203. Epub 2004 May 14.

In the absence of acetylcholinesterase inhibitors, S15535 dose-dependently (0.04-5.0 mg/kg s.c.) elevated dialysis levels of acetylcholine in the frontal cortex and dorsal hippocampus of freely moving rats.
