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.

Unknown MOA PfNF54

Plasmodium falciparum NF54

P. falciparum strain NF54 (PfNF54) was derived from a patient who had never left the Netherlands.
PfNF54 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.

Plasmodium falciparum Dd2

P. falciparum strain Dd2 (PfDd2) is a clone derived from PfW2, following continuous culture in mefloquine. PfW2 was cloned from the Indochina III/CDC isolate, originally derived from a Laotian patient who failed chloroquine therapy.
PfDd2 can be obtained from the Malaria Research and Reference Reagent Resource Center (MR4) and is reported to be resistant to chloroquine, pyrimethamine and mefloquine.

Plasmodium falciparum K1

P. falciparum strain K1 (PfK1) was isolated in Kanchanaburi, Thailand in 1979.
PfK1 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4) and is reported to be a multidrug-resistant strain.

Plasmodium falciparum FCR3

P. falciparum strain FCR3 (PfFCR3) was originally isolated from a patient in The Gambia, West Africa in 1976.
PfFCR3 can be obtained from the European Malaria Reagent Repository or the Malaria Research and Reference Reagent Resource Center (MR4). Differences in sensitivity of PfFCR3 clones to chloroquine have been reported, with the original isolate that was chloroquine sensitive rapidly acquiring resistance in culture (PMID: 7031656, PMID: 51801).
