GtoPdb Ligand ID: 14444

Compound class: Synthetic organic
Comment: BDM91288 is a pyridylpiperazine-based bacterial efflux pump inhibitor (EPI) with improved drug-like properties compared to earlier inhibitors from the series such as BDM88855 [1]. It has potent activity against the resistance-nodulation-division (RND) family of efflux pumps of Enterobacteriaceae, binding to AcrB, the inner membrane component of the AcrAB-TolC efflux pump [1]. EPIs have potential clinical utility as adjunctive therapeutic agents for the treatment of infections caused by Gram-negative pathogens.

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
BDM91288 has been shown to decrease the MIC of a panel of antibacterial agents (including levofloxacin, tetracycline, cefepime, ceftazidime, aztreonam, and meropenem) against Klebsiella pneumoniae in vitro [1]. The same study found that BDM91288 improved the in vivo efficacy of levofloxacin treatment in a mouse model of K. pneumoniae lung infection.
