General description

A synthetic cell-permeable actinobacteria pyrimidotriazine-dione that selectively disrupts β-catenin-Tcf4 interaction (IC50 = 0.8 µM in cell-free binding assays) and inhibits β-catenin-regulated cellular transcription activity (IC50 = 0.3 µM in HCT116-based reporter assays). PKF118-310 is demonstrated to reverse β-catenin, but not siamois, mRNA-induced ventral body axis formation in Xenopus embryos, while direct tumor site injection (1 mg/kg/0.5 wk) in HepG2 xenograph mice is shown to increase the number of apoptotic cells and decrease the expression of β-catenin target genes (cyclin D1, c-Myc, survivin) in the tumor mass, resulting in an effective tumor growth retardation (by ~60% after a 4-wk treatment period) in vivo.

The Dlx5 homeobox gene was first implicated as an oncogene in a T-ALL mouse model expressing myristoylated (Myr) Akt2. Furthermore, overexpression of Dlx5 was sufficient to drive T-ALL in mice by directly activating Akt and Notch signaling. These findings implied
