Xanomeline (LY-246,708) is an orthosteric muscarinic acetylcholine receptor (mAChR) agonist, often referred to as M1/M4-preferring. It is also known to act as a M5 receptor antagonist. Xanomeline was studied in clinical trials phase I in schizophrenia. In Phase II clinical trials in Alzheimer’s patients, xanomeline significantly improved several measures of cognitive function, yet produced unwanted side effects that limited patient compliance. The side effects seem to be associated with rapid metabolism of the alkyloxy side chain following oral administration, resulting in a nonselective, yet active compound with limited therapeutic utility. Despite a second Phase II clinical trial with a patch formulation, the liabilities of xanomeline still outweigh its benefits.

Xanomeline tartrate 75 mg TID, for 225 mg total daily dose Placebo, TID
Route of Administration:
Oral
CHO cells, stably expressing the human M5 muscarinic acetylcholine receptor were incubated for 1 h at 37°C in the absence or presence of xanomeline (1, 10, or 30 μM). Further experiments were designed to assess whether xanomeline, a partial agonist, can act as an antagonist to a full agonist at the M5 receptor. Cells were incubated for 1 h with 3 μM carbachol in the absence or in the presence of increasing concentrations of xanomeline. Xanomeline was able to antagonize the ability of carbachol to stimulate PI production in a concentration-dependent manner down to the level of maximal receptor activation by xanomeline alone.
