Description

KRpep-2d is a potent K-Ras inhibitor and inhibits proliferation of K-Ras-driven cancer cells. KRpep-2d can be used for cancer research[1].

IC50 & Target[1]

K-RAS

 

In Vitro

KRpep-2d has cyclic structure with importance for K-Ras inhibitory activity. Leu77 , Ile9 and Asp12 are critical amino acid residues for the K-Ras inhibitory activity of KRpep-2d[1].
KRpep-2d (10-30 μM) has inhibitory activity of A427 cells with the proliferation rates of 68.3% (10 μM) and 48.3% (10 μM)[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.
