KY-02327, a metabolically stabilized KY-02061 analog, is a potent Dishevelled (Dvl)-CXXC5 interaction inhibitor. KY-02327 shows an activating effect on the Wnt/β-catenin pathway, resulting in promotion of osteoblast differentiation[1].

KY-02327 (1-10 μM; 2 days; MC3T3E1 cells, a murine pre-osteoblast cell line) increases β-catenin protein level together with Runx2 and accumulated nuclear β-catenin in a dose-dependent manner[1].KY-02327 (1-10 μM) increases the mRNA levels of osteoblast differentiation markers collagen 1a (Col1a) and osteocalcin (OCN)[1].

KY-02327 (20 mg/kg; p.o.; 5 sequential days per week for 4 weeks) successfully rescues bone loss in the ovariectomized (OVX) mouse model[1].
