Background:

Ripretinib (DCC-2618) is an orally bioavailable, selective KIT and PDGFRA switch-control inhibitor. Ripretinib (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. Ripretinib (DCC-2618) also inhibits multiple other kinase targets, such as FLT3 and KDR (or VEGFR-2)[1][2]. DCC-2618 exerts antineoplastic effect and induces apoptosis[3].

Ripretinib (DCC-2618) suppresses phosphorylation of KIT and decreases the expression of phosphosphorylated (p)STAT5, pAKT and pERK1/2 in neoplastic mast cells. Ripretinib inhibits the growth of ROSAKIT K509I cells with an IC50 of 34 ± 10 nM, and also induces apoptosis in these cells. Ripretinib (0.1-1.0 μM) inhibits IgE-dependent histamine release from basophils and spontaneous tryptase release from neoplastic mast cells, and also counteracts growth and survival of leukemic monocytes and blast cells at 0.01-5 μM[2].Ripretinib (DCC-2618) is a pan-KIT and PDGFRA inhibitor, shows cytotoxic activity against gastrointestinal stromal tumors[4].
