Hodoodo CAT#: H522531
CAS#: 634616-95-8
Description: TBPB is a highly selective Muscarinic M1 receptor allosteric agonist. TBPB activates M1 through an allosteric site rather than the orthosteric acetylcholine binding site, which is likely critical for its selectivity. TBPB displays unprecedented functional selectivity at the M₁ mAChR. TBPB is a bitopic ligand, interacting with both the orthosteric site and an allosteric site, at the M₁ mAChR.
