BBO-11818
Based on 1 Customer Validation
BBO-11818 is an orally active, highly selective (relative to NRAS and HRAS), non-covalent pan-KRAS inhibitor (IC50=28-120 nM). BBO-11818 specifically binds to the Switch-II/Helix 3 pocket, disrupts the KRAS:RAF1 interaction by inducing conformational changes, and blocks the MAPK signaling pathway. BBO-11818 exhibits significant anti-tumor activity, which not only inhibits cell proliferation and induces apoptosis, but also drives tumor regression in xenograft models. BBO-11818 produces synergistic effects when combined with Cetuximab (HY-P9905), anti-PD-1 antibody or PI3Kα inhibitor. BBO-11818 is used in the research of KRAS mutation-related malignancies such as pancreatic cancer, non-small cell lung cancer and colorectal cancer.
