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.

Bioactivity Comments
Epetraborole has activity in vitro against multidrug-resistant Gram-negative bacteria spp., including Pseudomonas aeruginosa (MIC90 of 1-4 μg/ml) and Enterobacteriaceae bearing NDM-1 and KPC carbapenemases (MIC90 of 0.5-2μg/ml) [2]. Epetraborole also demonstrates activity against Mycobacterium abscessus both in vitro (MIC of 0.28-0.56 μM) and in a mouse model of M. abscessus infection [1].
