KRAS4b-PDEδ stabilizer C19 is a stabilizer of the KRAS4b-PDEδ complex which decreases the proliferation of colorectal cancer cells, and increases apoptosis via decreased activation of oncogenic KRAS4b signaling.
KRAS4b-IN-D14 is a specific inhibitor of oncogenic KRAS4b signaling which stabilizes the KRAS4b-PDEδ complex and remarkably decreases tumor size and triggered apoptosis of tumor cells.
