    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 206497

CAS#: 1442472-39-0 (free base)

Description: Ripretinib, also known as DCC-2618, is a potent, orally active and selective KIT/PDGFR inhibitor with potential antineoplastic activity. DCC-2618 targets and binds to both wild-type and mutant forms of KIT and PDGFRa specifically at their switch pocket binding sites, thereby preventing the switch from inactive to active conformations of these kinases and inactivating their wild-type and mutant forms. In May 2020, FDA Approves Qinlock (ripretinib) for the Treatment of Fourth-Line Gastrointestinal Stromal Tumor
