GtoPdb Ligand ID: 12898

Synonyms: compound 195 [WO2021113557A1] | NX-5948 | NX5948
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: NX-5948 (Nurix Therapeutics) is an oral BTK protein degrader. It was designed as an alternative to BTK inhibitors for potential to treat B cell malignancies, including those that carry BTK mutations which confer resistance to existing BTK inhibitors [1-2]. In contrast to NX-2127 which degrades both BTK and IKZF3, NX-5948 selectively degrades BTK. We believe NX-5948 is compound 195 in patent WO2021113557A1 [3]. It is a structure match for the INN bexobrutideg (WHO INN proposed list 133, July 2025).

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.
