BI-2852 is RAS inhibitor that binds RAS switch I and II (SI/II) pocket in both the active and inactive forms (GCP-/GDP-bound KD in μM = 0.74/2.0 (KRAS-G12D), 7.5/1.1 (KRAS), 0.57/2.5 (HRAS), 1.3/8.3 (NRAS)). BI-2852 inhibits RAS-mediated signaling and proliferation of KRAS-G12C-bearing NCI-H358 lung cancer cells (EGF-induced pERK IC50 = 5.8 μM; GI50 = 6.7 μM in soft agar with low serum) by blocking KRAS interactions with GEF SOS1 (GDP-bound G12C/G12D IC50 = 450/260 nM, GTP-bound Wt/G12C/G12D IC50 = 490/360/490 nM) and effectors CRAF (GTP-bound Wt/G12C/G12D IC50 = 1740/80/770 nM) and PI3Kα (GTP-bound Wt/G12C/G12D IC50 = 250/100/500 nM).
