KRpep-2d (TFA) 是一种有效的K-Ras抑制剂，抑制 K-Ras 驱动的癌细胞增殖。KRpep-2d (TFA) 可用于癌症研究。
KRpep-2d (TFA) 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 (TFA) (10-30 μM) has inhibitory activity of A427 cells with the proliferation rates of 68.3% (10 μM) and 48.3% (10 μM)[1].
