ACBI3

ACBI3 (compound 7), a chemical probe, is a PROTAC targeting KRAS. ACBI3 is composed of PROTAC target protein ligand pan-KRAS degrader 1 (HY-162960) (red part), E3 ligase ligand E3 ligase Ligand 43 (HY-401613) (blue part) and PROTAC Linker 1-Bromo-4-(ethynyloxy)butane (HY-169992) (black part), among which the conjugate of E3 ubiquitin ligase ligand + Linker is E3 Ligase Ligand-linker Conjugate 143 (HY-169995). ACBI3 achieves in vivo degradation of oncogenic KRAS, resulting in durable pathway modulation and tumor regressions in KRAS mutant xenograft mouse models[3].
