GtoPdb Ligand ID: 12886

Synonyms: ABBV-CLS-7262 | compound 131 [US20220251123A1]
Compound class: Synthetic organic
Comment: The structure for fosigotifator was obtained from proposed INN list 129 (August 2023) where it is described as a eukaryotic translation initiation factor 2B (eIF2B) activator. Fosigotifator is one of the prodrug compounds claimed in patent US20220251123A1 [2]. It is likely that this is the Abbvie/Calico CNS-penetrant clinical lead ABBV-CLS-7262, that is designed to activate eIF2B and thereby modulate the integrated stress response (ISR) [4] as a mechanism to treat a range of conditions, including neurodegenerative and metabolic diseases [1,3,5].

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the CDK toolkit. 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.
