Pan KRas-IN-1 (example 5) shows high binding capacity to KRas, with IC50s of <2 nM among different KRas isform, including G12D, G12V, G12R, G12A, G12S, G13D, Q61H, and WT[1].
Pan KRas-IN-1 inhibits the phosphorylation of ERK downstream of KRas in different cells; AsPC-1 (G12D, IC50=9 nM), A549 (G12S, IC50=11 nM), HCT116 (G13D, IC50=23 nM), NCI-H358 (G12C, IC50=6 nM), NCI-H460 (Q61H, IC50=12 nM), NCI-H727 (G12V, IC50=29 nM), MKN1 (WT, IC50=32 nM), PSN-1 (G12R, IC50=681 nM)[1].
Pan KRas-IN-1 (0-3000 nM; 5 d) exhibits anti-proliferative activity against mutation of reststance to Adagrasib in mouse 3T3 fibroblasts, with IC50s of 32 nM (G12A), 28.1 nM (G12C), 20.25 nM (G12D), 1742 nM (G12R), 94 nM (G12V), 50 nM (G12W), 610 nM (G13D), 58 nM (Q61H)[1]. |
