MCB-36
Based on 1 Customer Validation
MCB-36 is a VHL-recruiting pan-KRAS PROTAC degrader without affecting KRAS transcription. MCB-36 exhibits minimal effects on HRAS and NRAS protein levels. MCB-36 binds to the GDP-loaded state of G12D, G12C, G12V, and wild-type KRAS with high affinities Kd ≈ 1 pM). MCB-36 decreases p-ERK levels, leading to cell apoptosis. MCB-36 effectively suppress KRASG12C inhibitor-resistant cancer cells and remodel the tumor immune microenvironment. MCB-36 can be used for the study of colorectal cancer and lung cancer (Pink: Target protein ligand; Blue: E3 ligand (HY-112078); Black: Linker (HY-W091879)).

MCB-36 (1 nM-100 μM, 5 days) shows significant anti-proliferative effects on KRAS-dependent cancer cells that rely on KRAS (as PC-1 (G12D), H358 (G12C), LS180 (G12V), HCT116 (G13D), etc.) for growth and survival (24 of 30 cell lines tested with a mean IC50 of around 1 μM) while sparing normal cells (hTERT-HPNE, NCM460) and KRAS-independent cells (IC50 > 10 μM)[1].
MCB-36 (0-10 μM, 0-72 h) effectively degraded KRAS protein, decreased p-ERK levels and induced cell death in all cell lines tested including MIA PaCa-2 cells expressing KRASG12C, KRASG12C/Y96C, and KRASG12C/H95D[1].
MCB-36 (0-2.5 μM, 6 days) suppresses the growth of KRAS-mutant colorectal cancer organoids, accompanied by reduced abundance of MAPK signaling components and reciprocal induction of apoptotic markers.
MCB-36 significantly upregulates the interferon-alpha response pathway in CD45+ immune cells isolated from CT26 tumors and increases the abundance of effector CD8+ T cells[1].
