Biochem/physiol Actions

Orally active, small molecule activator of PP2A (SMAP) with anti-cancer efficacy in cultures and in animals in vivo.

DT-061 is an orally active, small molecule activator of PP2A (NZ-8-061; SMAP1) that drives protein phosphatase 2 (PP2, PP2A) conformational changes by targeting the scaffold subunit Aα. DT-061 induces apoptotic death in cancer cultures (A549, H441, H358 IC50 ≤10 uM by MTT assay) and in mice in vivo (15 mg/kg with KRASLA2 transgenic model or 5 mg/kg with PDX tumor fragments or H358 xenograft model; via b.i.d. oral gavage) with little adverse effects to the animals.
