M4 mAChR Modulator-1 (compound 23i) acts as a positive allosteric modulator (PAM) of the M4 mAChR. It demonstrates a stronger synergistic effect in β-arrestin recruitment compared to G protein activation when interacting with ACh. Additionally, while its PAM effects are weaker in G protein-mediated responses, they are more potent in β-arrestin recruitment.

Clozapine (HF 1854) is a tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity.

Tropicamide (Ro 1-7683) is a synthetic muscarinic antagonist with anticholinergic properties similar to atropine. Upon ocular administration, it binds to and blocks muscarinic receptors in the sphincter and ciliary muscles, inhibiting cholinergic responses and causing pupil dilation and ciliary muscle paralysis. Tropicamide is used as a diagnostic agent to induce short-duration mydriasis and cycloplegia.

Clozapine (HF 1854) dihydrochloride is utilized for researching psychiatric disorders. This compound exhibits high affinity for numerous neuroreceptors and acts as an effective antagonist of dopamine receptors, with a Ki value of 75 nM. Clozapine inhibits the muscarinic M1 receptor and serotonin 5HT2A receptor, with Ki values of 9.5 nM and 4 nM, respectively. Additionally, Clozapine is a selective agonist of the muscarinic M4 receptor (EC50 = 11 nM).

AF-DX 384 free base is a selective and efficient M2 muscarinic acetylcholine receptor (M2 mAChR) and M4 muscarinic acetylcholine receptor (M4 mAChR) antagonist. It can be used for research on neurodegenerative diseases like Parkinson's.
