Approved drug
lusutrombopag is an approved drug (Japan (2015), FDA (2018), EMA (2019))
Compound class: Synthetic organic
Comment: Lusutrombopag is an orally bioavailable, nonpeptidyl, small molecule thrombopoietin (TPO) receptor agonist [3] that was developed by Shionogi in Japan. It was the second TPO receptor agonist to receive FDA approval in 2018 (avatrombopag was the first).

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.

Summary of Clinical Use Click here for help
Lusutrombopag was first approved in Japan in 2015, to increase platelet count (and thus reduce bleeding risk) in patients with chronic liver disease-induced thrombocytopenia and who are scheduled for invasive surgery [2]. FDA approval for the same use was granted in July 2018 [1]. Lusutrombopag has completed Phase 2 clinical evaluation in patients with autoimmune thrombocytopenia (NCT01129024).
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Lusutrombopag selectively activates the human TPO receptor which promotes the proliferation and differentiation of bone marrow cells into megakaryocytes, and increases platelet levels.
