GtoPdb Ligand ID: 10037

Synonyms: KPT-8602 | KPT8602
Compound class: Synthetic organic
Comment: Eltanexor (KPT-8602) is a second-generation, orally bioavailable, selective inhibitor of the nuclear export protein XPO1, that works in the same way as its first-in-class relation selinexor. In comparison to selinexor, eltanexor exhibits much lower brain penetration, and this appears to reduce the central nervous system-mediated side effects of anorexia and weight loss detected with selinexor therapy [1]. Eltanexor is being investigated for therapeutic antineoplastic potential [1-3].

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 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.
