Biological Activity
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].
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].
