HRX-0233 (HRX0233) is a potent and selective inhibitor of MAP2K4 (MKK4), a kinase involved in the stress-activated protein kinase (SAPK) signaling pathway. MAP2K4 plays a role in regulating cellular responses to stress, apoptosis, and tumorigenesis. HRX-0233 has shown particular promise in KRAS-mutant cancers, where it exhibits synergistic effects with RAS inhibitors, making it a potential candidate for combination therapy in these difficult-to-treat cancers.
