Description
LC-2 is the first PROTAC capable of degrading endogenous KRAS(G12C). It covalently binds KRASG12C with a MRTX849 warhead and recruits the E3 ligase VHL, inducing rapid and sustained KRASG12C degradation leading to suppression of MAPK signaling in both homozygous and heterozygous KRASG12C cell lines.

How to use
In Vitro:
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 DC50s 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.
