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
Approved to lower total cholesterol in patients with homozygous familial hypercholesterolemia (HoFH). Clinical formulations contain lomitapide mesylate (PubChem CID 11274333).
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Mechanistically lomatipide inhibits microsomal triglyceride transfer protein (MTTP, P55157). MTTP is required for the transport of triglyceride, cholesteryl ester, and phospholipid between phospholipid surfaces in the endoplasmic reticulum and this activity is required for the synthesis of apolipoprotein B (apo B). Lomatipide-induced reduction of apoB reduces VLDL and chylomicron formation and thus reduces LDL-cholesterol levels. Note that the microsomal triglyceride transfer protein is a heterodimer, composed of MTTP and protein disulfide isomerase (PDI, of which there are many isoforms).
