GtoPdb Ligand ID: 13348

PDB Ligand
Compound class: Synthetic organic
Comment: AZ1 is a sulfonyl piperazine compound with antibacterial activity, discovered using a high-throughput phenotypic screen [3]. It is a novel inhibitor of bacterial cell wall synthesis that acts by targeting UDP-2,3-diacylglucosamine hydrolase (LpxH), an enzyme in the lipopolysaccharide synthesis pathway [1]. LpxH is an essential enzyme, conserved in the majority of Gram-negative bacteria but absent in human, and an attractive target for antibacterial development.

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.

Bioactivity Comments
An initial study found that although AZ1 lacked activity against most of the Gram-negative and Gram-positive bacteria tested, it did inhibit the growth of an Escherichia coli efflux mutant (W3110 ΔtolC) with a MIC of 0.25μg/ml [3]. AZ1 is also reported to have activity against wild-type Klebsiella pneumoniae [2].
