LC-2 is a potent and first-in-class von Hippel-Lindau-based PROTAC capable of degrading endogenous KRAS G12C, with DC50s between 0.25 and 0.76 μM. LC-2 covalently binds KRAS G12C with a MRTX849 warhead and recruits the E3 ligase VHL, inducing rapid and sustained KRAS G12C degradation leading to suppression of MAPK signaling in both homozygous and heterozygous KRAS G12C cell lines.

Description

LC-2 is a potent and first-in-class von Hippel-Lindau-based PROTAC capable of degrading endogenous KRAS G12C, with DC50s between 0.25 and 0.76 μM[1]. LC-2 covalently binds KRAS G12C with a MRTX849 warhead and recruits the E3 ligase VHL, inducing rapid and sustained KRAS G12C degradation leading to suppression of MAPK signaling in both homozygous and heterozygous KRAS G12C cell lines[2].

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[1].
LC-2-induced (2.5 μM; 6-24 hours) KRAS G12C degradation modulates Erk signaling in homozygous and heterozygous KRAS mutant cell lines[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (1.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.08 mg/mL (1.84 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
