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.

Summary of Clinical Use Click here for help
Arbekacin is a potent aminoglycoside antibacterial already approved in some countries to treat multidrug-resistant bacteria. An inhalation solution of arbekacin (ME1100) is being developed for the treatment of hospital-acquired and ventilator-associated bacterial pneumonia.

Several aminoglycoside antibacterials, including arbekacin, have been reported to have the ability to promote mRNA translation even in the presence of premature termination codons (PTCs) in mutated genes. In the absence of pharmaceutical intervention, the ribosomal translation process produces truncated, often non-functional protein products. However, in the presence of such compounds the ribosomes 'readthrough' the PTCs, producing increased amounts of full-length, functional protein. This developing pharmaceutical intervention has been termed 'readthrough strategy' and has led to a repurposing effort, with the compound now being evaluated in clinical trial as a treatment for Duchenne muscular dystrophy (DMD), in patients where the inherited genetic mutation causes production of truncated, non-functional dystrophin. Dystrophin is a protein critical for muscle function. For more information regarding current clinical trials testing arbekacin, visit www.clinicaltrials.gov.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Arbekacin promotes ribosomal readthrough of PTCs, thereby increasing transcription of full-length, functional proteins.
