物化性质 | 生物活性 LC-2 是首创的内源性 KRAS G12C 的 PROTAC 降解剂,DC50 在 0.25 和 0.76 μM 之间。LC-2 是一种 PROTAC,与 MRTX849 共价结合 KRAS G12C 并招募 E3 连接酶 VHL,诱导 KRAS G12C 快速持续降解,导致纯合和杂合子 KRAS G12C 细胞系 MAPK 信号的抑制。 |
体外研究 | LC-2 induces degradation of endogenous KRASG12C in multiple KRAS mutant cancer cell (NCI-H2030, MIA PaCa-2, SW1573, NCI-H23 and NCI-H358 cells) with DC 50 s between 0.25 and 0.76 μM. LC-2-induced KRASG12C degradation occurs via a bona fide PROTAC mechanism. MIA PaCa-2, NCI-H23, and SW1573 cells are treated with 2.5 μM of LC-2 for 6, 24, 48, and 72 h. In all three cell lines, maximal KRAS degradation occurred within 24 h and was sustained up to 72 h. LC-2-induced (2.5 μM; 6-24 hours) KRAS G12C degradation modulates Erk signaling in homozygous and heterozygous KRAS mutant cell lines. Western Blot Analysis Cell Line: MIA PaCa-2 cells and NCI-H23 cells Concentration: 2.5 μM Incubation Time: 6-24 hours Result: Inhibition and degradation of KRAS G12C decreases pErk signaling at 6 and 24 h in homozygous MIA PaCa-2 cells |
