Description
ONC206 is an analogue of TRAIL inducer ONC201 and is a selective antagonist of the D2-like dopamine receptors (DRD2/3/4) at nanomolar concentrations. ONC206 also has broad-spectrum anti-tumor activity. ONC206 (Oncoceutics) is an imipiridone with nanomolar potency and analogue of ONC201, a selective dopamine receptor D2 (DRD2) antagonist currently being investigated in phase II clinical trials for serous endometrial cancer (SEC) . ONC206 inhibited cellular proliferation in a dose-dependent manner and was more potent than ONC201 in the ARK1 (IC50 = 0.33 M vs. IC50 = 1.59uM) and SPEC-2 (IC50 = 0.24uM vs. IC50 = 0.81uM) cell lines. Treatment with ONC206 resulted in induction of ROS production and reduction of mitochondrial membrane potential, accompanied by an increase in cleaved caspase-3 and caspase-9 activity (p < 0.01) . ONC206 also significantly inhibited cellular adhesion and migration in both cell lines (p < 0.01) . Pretreatment with the stress inhibitor N-acetylcysteine (NAC) significantly attenuated the efficacy of ONC206 on cell proliferation, ROS production and cellular invasion. ONC206 demonstrates nanomolar potency for the inhibition of proliferation in SEC cells. ONC206 (100 mg/kg; p.o.; every 10 days) reduces obviously tumor growth inhibition.

Chemical Information

Onc-206

DRD2 Antagonist/ClpP Agonist ONC206 is an orally bioavailable, selective bitopic dopamine receptor D2 (DRD2) antagonist and mitochondrial caseinolytic protease P (ClpP) agonist, with potential antineoplastic activity. Upon administration, DRD2 antagonist/ClpP agonist ONC206 targets, binds to and inhibits the activity of DRD2. This may inactivate Akt (protein kinase B) and extracellular signal-regulated kinase (ERK), which may result in inhibition of the phosphatidylinositol 3-kinase (PI3K)/Akt signal transduction pathway as well as the mitogen-activated protein kinase (MAPK)/ERK-mediated pathway. This may lead to the induction of tumor cell apoptosis mediated by tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)/death receptor type 5 (DR5; TRAIL receptor 2) signaling in tumor cells. In addition, ONC206 targets and binds to ClpP and induces proteolysis. This may disrupt mitochondrial structure and function in tumor cells and lead to tumor cell death. DRD2, a G protein-coupled receptor (GPCR), is overexpressed in various malignancies. It is activated by dopamine produced by the tumor cells or present in the tumor microenvironment (TME) and plays an important role in the pro-survival and stress signaling pathways. ONC206 is able to cross the blood-brain barrier (BBB).
