Approved drug
palovarotene is an approved drug (Canada (2022), FDA (2023))
Compound class: Synthetic organic
Comment: Palovarotene is an orally bioavailable, retinoic acid receptor gamma (RAR-γ) agonist. This compound was originally investegated for its potential to repair alveolar damage in emphysema and COPD [1,8], but it failed to demonstrate significant clinical efficacy. Ipsen acquired palovarotene when it purchased Clementia Pharmaceuticals in 2019, and they repurposed palovarotene for potential to reduce heterotopic ossification in patients with fibrodysplasia ossificans progressiva (FOP) [6,9].

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.

Bioactivity Comments
Palovarotene dose-dependently suppresses heterotopic ossification in mice [7]. We have been unable to find a publicly available affinity value for this agonist at its proposed primary target, retinoic acid receptor gamma (RARG), so have tagged the primary target based on biological evidence.
