RAS inhibitor Abd-7 is a powerful compound (Kd=51 nM) that binds to RAS and inhibits the protein-protein interaction (PPI) between RAS and its effectors. By interacting with RAS within cells, RAS inhibitor Abd-7 hinders RAS-effector interactions and suppresses endogenous RAS-dependent signaling. Additionally, RAS inhibitor Abd-7 disrupts the PPI of different mutant KRAS proteins with PI3K, CRAF, RALGDS, as well as NRAS Q61H and HRAS G12V[1].
β-Catenin-IN-37 is a selective inhibitor of the protein-protein interaction between β-Catenin and T-cell factor (Tcf), known as β-catenin/Tcf PPI. It effectively inhibits canonical Wnt signaling and impedes the growth of colorectal cancer cells SW480 and HCT116, with IC50 values of 20 μM and 31 μM, respectively.
PCSK9-IN-2 is a newly developed small molecule that effectively inhibits the protein-protein interaction (PPI) between PCSK9 and LDLR. It has been found to have a potent inhibitory activity with an IC50 value of 7.57 μM.
ZW4864 is an orally active and selective β catenin/B-Cell lymphoma 9 protein protein interaction ( β catenin/BCL9 PPI ) inhibitor. ZW4864 inhibits β catenin/BCL9 PPI with a K i value of 0.76 μM and an IC 50 value of 0.87 μM.
