GtoPdb Ligand ID: 13602

Synonyms: FP-802
Compound class: Synthetic organic
Comment: FP802 is a small molecule that acts to disrupt the protein-protein interaction between NMDA glutamate receptors (NMDARs) and transient receptor potential cation channel subfamily M member 4 (TRPM4) [3]. It is an analogue of brophenexin, with a chlorine atom replacing brophenexin's bromine atom [2]. In extrasynaptic neurons the NMDAR subunits GluN2A and GluN2B interact with the TwinF domain of TRPM4, to form a NMDAR/TRPM4 death signaling complex that mediates NMDA-triggered toxicity and neurodegeneration. This new class of agents have been named collectively as TwinF interface (TI) inhibitors and they are being explored for anti-neurodegenerative/neuroprotective effects [1]. Experimental evidence indicates that TIs act only as protein-protein interaction inhibitors, and do not alter the channel activity or expression of NMDARs or TRPM4.

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.
