NCB-0846

NCB-0846 is an orally active, selective inhibitor for Wnt, that inhibits Traf2- and Nck-interacting kinase (TNIK) with an IC₅₀ of 21 nM. NCB-0846 blocks TGF-β signaling pathway by inhibiting SMAD2/3 phosphorylation and nuclear translocation^[1][2]. IC50 & Target:IC50: 21 nM (TNIK)^[1] In Vitro:NCB-0846 has anti-Wnt activity. NCB-0846 binds to TNIK in an inactive conformation, and this binding mode seems to be essential for Wnt inhibition. NCB-0846 shows inhibitory activity against TNIK with an IC₅₀ of 21 nM. NCB-0846 also inhibits FLT3, JAK3, PDGFRα, TRKA, CDK2/CycA2, and HGK. NCB-0846 induces faster migration of TCF4 phosphorylated by TNIK within a concentration range of 0.1-0.3 μM and completely inhibits the phosphorylation of TCF4 at a concentration of 3 μM. NCB-0846 inhibits HCT116 cell growth and shows much higher (-20-fold) inhibitory activity against colony formation by the same cells in soft agar^[1]. In Vivo:NCB-0846 suppresses the growth of tumors established by inoculating HCT116 cells into immunodeficient mice. The expression of Wnt-target genes (AXIN2, MYC and CCND1) in xenografts is reduced following the administration of NCB-0846. NCB-0846 induces an increase in the sub-G1 cell population. Cleavage of poly (ADP-ribose) polymerase 1 indicates the induction of apoptosis^[1].
