FTI 276 TFA	Farnesyl Transferase Ras p38 MAPK	Cancer
FTI 276 TFA is a farnesyltransferase (FTase) inhibitor with an IC₅₀ of 0.5 nM, and it exhibits selectivity for FTase over geranylgeranyltransferase I (GGTase I). FTI 276 TFA blocks the farnesylation of H-Ras and K-Ras4B, causes inactive Ras-Raf complexes to accumulate in the cytoplasm, and inhibits constitutive MAPK activation. FTI 276 TFA reduces the number, incidence and volume of tumors, and restricts the growth of tumors expressing activated K-ras. FTI 276 TFA can be used in research related to pulmonary adenoma .

HY-15873

*FTI 276*	Farnesyl Transferase	Cancer
FTI-276 is a protein farnesyl transferase (PFT) inhibitor with IC₅₀s of 0.9 and 0.5 nM for Plasmodium falciparum and human.

HY-115489

GGTI-286	Ras	Cancer
GGTI-286, a potent and cell-permeable GGTase I inhibitor, is 25-fold more potent (IC₅₀=2 μM) than the corresponding methyl ester of FTI-276 (HY-15873A). GGTI-286 selectively inhibits geranylgeranylation of Rap1A over farnesylation of H-Ras in NIH3T3 cells (IC₅₀s=2 and >30 μM, respectively). GGTI-286 also potently inhibits oncogenic K-Ras4B stimulation with an IC₅₀ of 1 μM .

GGTI-286 TFA also potently inhibits oncogenic K-Ras4B stimulation with an IC₅₀ of 1 μM .

HY-117935

GGTI-286 hydrochloride	Ras	Cancer
GGTI-286 hydrochloride, a potent GGTase I inhibitor, is 25-fold more potent (IC₅₀=2 μM) than the corresponding methyl ester of FTI-276 (HY-15873A).

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
