简介内容：GGTI-286 TFA is a potent, cell-permeable inhibitor of GGTase I, exhibiting 25 times greater effectiveness (IC 50 = 2 μM) compared to the corresponding methyl ester of FTI-276. It specifically targets the geranylgeranylation of Rap1A, demonstrating significant selectivity over the farnesylation of H-Ras in NIH3T3 cells (IC 50s = 2 and >30 μM, respectively). Additionally, GGTI-286 TFA effectively inhibits the stimulation of oncogenic K-Ras4B with an IC 50 of 1 μM.
