GtoPdb Ligand ID: 13410

Compound class: Synthetic organic
Comment: Lolamicin is an antibacterial with potential to avoid disruption of the gut microbiota. It has specific activity against Gram-negative pathogenic bacteria, while selectively sparing Gram-negative and Gram-positive commensal strains [2]. Lolamicin is an inhibitor of lipoprotein CDE (LolCDE) [2], a complex found in the membrane of Gram-negative bacteria. It is one of the chemical structures claimed in patent WO2023091873A1 from the University of Illinois [1].

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
Lolamicin has activity in vitro against laboratory strains of Gram-negative pathogens including Escherichia coli (MIC of 0.008-2 μg/ml), Klebsiella pneumoniae (MIC of 1-4 μg/ml) and Enterobacter cloacae (MIC of 1-4 μg/ml), but not Gram-positive pathogens or Gram-negative and Gram-positive gut commensal bacteria (MIC >128 μg/ml) [2].
