Biochem/physiol Actions

TBPB is a highly selective Muscarinic M1 receptor allosteric agonist. It activates M1 through an allosteric site rather than the orthosteric acetylcholine binding site, which is likely critical for its selectivity. Muscarinic 1 (M1) receptors are expressed in brain regions responsible for attention and memory, including hippocampus, cortex, and striatum. M1 activation is a proposed mechanism for increasing information processing in disease states, such as Alzheimer′s. M1 agonists are being studied as potential therapeutic agents to treat Alzheimer′s disease and the cognitive and negative symptoms of schizophrenia.
