ONC206

ONC206 is an analogue of TRAIL inducer ONC201[1]. ONC206 is a selective antagonist of the D2-like dopamine receptors (DRD2/3/4) at nanomolar concentrations. ONC206 has broad-spectrum anti-tumor activity[2].

ONC206 selectively antagonizes the D2-like (DRD2/3/4), but not the D1-like (DRD 1/5), subfamily of dopamine receptors[2].ONC206 significantly inhibits tumor cell migration and invasion in vitro[1].ONC206 (0.05 μM; Over 48 hours) inhibits migration of ONC201- and TRAIL-resistant HCT116 Bax-/- cells without inducing cell death or inhibiting cell proliferation[1].ONC206 engages the ISR and TRAIL pathway leading to tumor growth arrest and cell death[1].ONC206 does not induce cell cycle arrest in a colorectal cell line with acquired ONC201-resistance[1]. Cell Proliferation Assay[1] Cell Line: HCT116 cells

ONC206 (100 mg/kg;p.o.; every 10 days) causes significant tumor growth inhibition[2].
