fti 276 tfa

FTI 276 TFA is effective against plasmodium falciparum and humans.It is a protein-based nikyltransferase (PFT) inhibitor with an IC50s of 0.9 nM and 0.5 nM, respectively.

FTI 277 TFA is a prodrug form of FTI 276 that inhibits farnesyltransferase (FTase) (IC50 = 0.5 nM). Inhibits H-Ras and K-Ras processing in whole cells (IC50 values are 0.1 and 10μM respectively) and disrupts constitutive H-Ras-specific activation of MAPK. Causes significant antiproliferative effects in human malignant glioma cells and many other tumor cell lines.

GGTI-286 TFA 是一种高效的细胞通透性 GGTase I 抑制剂，(IC50为 2 μM。在 NIH3T3 细胞中，GGTI-286 TFA 对 Rap1A 香叶香叶基化的抑制作用高于 H-Ras 的法尼化作用 (IC50s=2 和 >30 μM)。GGTI-286 TFA 还能有效抑制 K-Ras4B 刺激，IC50为 1 μM。
