製品説明 | KRpep-2d is a K-Ras(G12D) selective inhibitory cyclic peptide with selectivity against wild-type (WT) K-Ras and the K-Ras(G12C) mutant. The IC50 value is 1.6 nM. |
---|---|
in vitro | KRpep-2d binds to K-Ras(G12D)with a Kd of 8.9 nM and approximately 6-fold selectivity over WT K-Ras, leading to an extended dissociation half-life[1]. KRpep-2d significantly suppresses ERK-phosphorylation, downstream of K-Ras(G12D), along with A427 cancer cell proliferation at 30 μM peptide concentration[2]. |

実験の流れ | For the growth inhibition assay, A427 and A549 cells are seeded at 4000 and 2000 cells/well in 96-well plates, respectively. Cells are treated with the peptides on the following day. For the 3-day treatments, medium containing the peptides is replaced every day. Relative cell numbers are estimated using CellTiter-Glo according to the manufacturer's instructions. Luminescence is measured using an EnVision plate reader. Percent inhibition is calculated based on cell numbers at Day 0 as low control and at Day 3 without peptide as high control. |
