RO8994

RO8994 (Compound 4) is an orally active, highly potent and selective spiroindolinone p53-MDM2 inhibitor with an IC50 value of 5 nM (HTRF binding assays) and 20 nM (MTT proliferation assays). RO8994 induces up-regulation of p53 expression and Apoptosis in wild-type p53 cancer cells. RO8994 also inhibits tumor growth in the tumor xenograft model[1][2][3].
