GtoPdb Ligand ID: 5215

PDB Ligand Antimalarial Ligand
Compound class: Natural product or derivative
Comment: Luteolin is a flavone, a type of flavonoid, naturally occuring in a variety of plants. It has antimalarial activity, inhibiting the growth of P. falciparum during the intraerythrocytic stages of the parasite's lifecycle [1].

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

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 CDK toolkit. 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.

Unknown MOA Pf3D7

Plasmodium falciparum 3D7

P. falciparum strain 3D7 (Pf3D7) was derived from isolate NF54 by limiting dilution. The complete genome of Pf3D7 has been sequenced (GenBank: LN999946.1).
Pf3D7 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4) and is sensitive to a panel of antimalarial compounds including chloroquine and pyrimethamine.

Unknown MOA Pf7G8

Plasmodium falciparum 7G8

P. falciparum strain 7G8 (Pf7G8) was subcloned from the IMTM22 strain by limiting dilution. The original IMTM22 strain was isolated from a 12 year old male near Manaus, Brazil in 1980.
Pf7G8 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4). This strain is a gametocyte producer and is reported to be chloroquine-sensitive and pyrimethamine-resistant.
