Comment: Ripretinib (DCC-2618) is an orally bioavailable, potent pan-KIT and PDGFRα kinase inhibitor that was developed by Dicephera Pharmaceuticals. It was designed for the treatment of malignancies that are driven by KIT and/or PDGFRα, for example gastrointestinal stromal tumors, glioblastoma multiforme and systemic mastocytosis. Ripretinib has activity across a broad range of resistance mutations in its target kinases, that emerge in response to imatinib treatment. Ripretinib binds to the 'switch pocket' of KIT, a domain that regulates the enzyme's catalytic conformation. Compounds that act in this way are often referred to as switch control inhibitors [1]. Another example of a switch control inhibitor is avapritinib.
The chemical structure shown here matches that supplied to the WHO for the INN, and this is claimed in patent WO2010051373 [2] as Example 39. Note that some PubChem SIDs are linked to an incorrect structure (as represented in PubChem CID 46208890).

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.
