YN14-H

YN14-H is a potent mutant KRAS^G12C PROTAC degrader. The DC₅₀ values of YN14-H in NCI-H358 and MIA PaCa-2 cells are 28.9 nM and 18.1 nM, respectively, with corresponding IC₅₀ values of 42 nM and 21 nM. YN14-H degrades KRAS^G12C in a ubiquitin-proteasome system-dependent manner, thereby significantly inducing apoptosis and inhibiting cell migration. YN14-H can be used for targeting tumors with KRAS^G12C mutations (such as non-small cell lung cancer, pancreatic cancer, etc.).

In Vitro

YN14-H (500 ns) promotes the formation of more stable interactions in the KRAS^G12C-VHL ternary complex, which is evidenced by a binding free energy of -158.12 kJ/mol and the presence of 10 stable hydrogen-bond interactions between the two proteins^[1].
YN14-H (0.01 nM-1 μM) induces the formation of the KRAS^G12C-VHL ternary complex with high affinity, with a dissociation constant K_d of 18.8 nM^[1].
YN14-H (0-5 μM) potently induces the KRAS^G12C-VHL protein-protein interaction, which is validated by a strong relative AlphaScreen luminescent signal^[1].
YN14-H (1 μM; 8 h) most effectively promotes the interaction between endogenous KRAS^G12C and VHL in NCI-H358 cells^[1].
YN14-H (1 nM-10 μM; 72 h) potently degrades KRAS^G12C protein in NCI-H358 and MIA PaCa-2 cells, with a DC₅₀ of 28.9 nmol/L in the former and 18.1 nmol/L in the latter, and achieves a maximal degradation rate of over 95% in both cell types^[1].
YN14-H (0-10 μM; 72 h) potently inhibits the proliferation of NCI-H358 (IC₅₀ = 0.042 μmol/L) and MIA PaCa-2 (IC₅₀ = 0.021 μmol/L) cells, whereas it exhibits no cytotoxicity in non-KRAS^G12C cells even at concentrations up to 10 μmol/L^[1].
YN14-H (0.01-1 μM; 48 h) potently inhibits the levels of phosphorylated AKT and ERK in a concentration-dependent manner in NCI-H358 and MIA PaCa-2 cells^[1].
YN14-H (100 nM; 12 h) potently inhibits the migratory capacity of NCI-H358 and MIA PaCa-2 cells^[1].
YN14-H (100 nM; 48 h) induces apoptosis in 35.19% of NCI-H358 cells and 55.19% of MIA PaCa-2 cells, and its efficacy is superior to that of other tested degraders^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
