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.

Summary of Clinical Use Click here for help
Used in the treatment of hypertension and congestive heart failure. Marketing authorisation by the US FDA has been discontinued. There is no information regarding approval for clinical use of this drug on the European Medicines Agency website. Other national approval agencies may continue to grant marketing authorisation.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Metabolised to the active form spiraprilat, which inhibits angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. This in turn reduces the vasoconstrictive effects of angiotensin II leading to a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms leading to decreased vasopressor activity and decreased aldosterone secretion.
