PDB Ligand
Compound class: Synthetic organic
Comment: MK-8719 is an inhibitor of O-GlcNAcase (OGA) that is being investigated as a disease modifying strategy for neurodegenerative tauopathies (including Alzheimer's disease, Pick's disease and progressive supranuclear palsy) [3]. Development of MK-8719 is the result of a partnership between Merck and Alectos Therapeutics. MK-8719 was designed using on the scaffold of the carbohydrate-based lead molecule thiamet-G and used medicinal chemistry and SAR to improve on thiamet-G's less than favourable drug-like properties (e.g. potency, selectivity, CNS exposure and metabolic stability). The current status of OGA inhibitor development as a novel preventative mechanism in neurodegeneration and age-related memory impairment is reveiwed by Rudrawar and Ryan (2019) [2].

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.

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.
