KRASG12D-IN-8

KRASG12D-IN-8 is an orally active KRAS^G12D inhibitor, with a K_d value of 0.003 nM for KRAS^G12D and 0.024 nM for KRAS^G12V. KRASG12D-IN-8 inhibits the activity of phosphorylated ERK in KRAS-mutated cells. KRASG12D-IN-8 induces tumor regression in ovarian cancer xenograft mouse models. KRASG12D-IN-8 can be used for the research of KRAS-mutated cancers.

In Vitro

KRASG12D-IN-8 (Compound 12) binds to KRAS^G12D with a K_d of 0.003 nM and to KRAS^G12V with a K_d of 0.024 nM, exhibiting exceptional high-affinity interactions with both mutant KRAS proteins^[1].
KRASG12D-IN-8 has a low efflux permeability of 15.4 ×10⁻⁶ cm/s in MDCK cells, with intrinsic clearance values of 338 μL/min/mg in human liver microsomes and 542 μL/min/mg in mouse liver microsomes^[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.
