GtoPdb Ligand ID: 9228

Synonyms: PF06767832
Compound class: Synthetic organic
Comment: PF-06767832 (compound 38) is an orally bioavailable, positive allosteric modulator (PAM) selective for the M1 muscarinic acetylcholine receptor (CHRM1) [2]. It is one of the compounds claimed in patent WO2016009297 [1]. M1 receptor PAMs are being designed for their potential to provide novel therapies for the treatment of M1-mediated diseases and disorders such as Alzheimer's disease.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Mechanism Of Action and Pharmacodynamic Effects Click here for help
In relation to Alzheimer's disease, stimulation of the M1 receptor has been shown to increase formation of the neuroprotective soluble amyloid precursor protein alpha (sAPPa; a proteolyte of APP cleavage by α-secretase), and in so doing, prevents the formation of the Αβ peptide [3]. However, despite not activating the M2 or M3 receptors, in vivo testing in dogs reveals that positive allosteric modulation of M1 causes the gastrointestinal and cardiovascular side-effects (cholinergic liabilities) , that were originally attributed to M2 and M3 receptor activation [2].
