FTI 277 (CAS 1217447-06-7): R&D Systems
Catalog Number: 2407
Chemical Name: N-[4-[2(R)-Amino-3-mercaptopropyl]amino-2-phenylbenzoyl]methionine methyl ester trifluoroacetate salt
Biological Activity
Prodrug form of FTI 276 (Cat. No. 2406) that inhibits farnesyltransferase (FTase) (IC50 = 0.5 nM). Inhibits H-Ras and K-Ras processing in whole cells (IC50 values are 0.1 and 10 μM 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.
