fti-276

FTI-276 is an inhibitor of protein farnesyltransferase (PFT) (IC50s: 0.9 and 0.5 nM for Plasmodium falciparum and human).

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.

BIM-46050 is a potent and specific inhibitor of human farnesyltransferase. BIM-46050 is free acidic form of BIM-46068. The IC50 values for in vitro inhibition of human brain FTase indicate that BIM-46050 and the ester form BIM-46068 are potent inhibitors of farnesyltransferase. Their potencies are in the nanomolar range and compare favorably with the compounds B581, FTI-277 and L745,631. B581 is an analog of the tetrapeptide Cys-Val-Phe-Met obtained by replacement of the amino-terminal amide bonds inhibiting processing of farnesylated proteins specifically. FTI-277 is a methyl ester of FTI-276, reported as a preferential inhibitor of FTase over GGTase I (100-fold). L745,631 is a 2-substituted piperazine reported to be a highly selective inhibitor of FTase over GGTase (2,000-fold). The selectivity of BIM-46050 and BIM-46068 for FTase over GGTase is very similar for both compounds (3,000-fold).

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。
