Gliotoxin is an immunosuppressive mycotoxin produced by pathogenic strains of Aspergillus and other fungi with diverse biological activities. It inhibits 20S proteasomal chymotrypsin activity (IC50 = 10 µM), blocking the degradation of IkappaBalpha and preventing the activation of NF-kappaB. Gliotoxin induces...

Post-translational protein prenylation, a process catalyzed by three different enzymes, occurs at the C-terminal of a number of proteins involved in cell growth control and oncogenesis. One of these enzymes, geranylgeranyltransferase I (GGTase I) modifies cysteines of proteins with CAAX terminal sequences,...

Tipifarnib is a nonpeptidomimetic, CAAX-competitive inhibitor of farnesyltransferase (IC50 = 0.86 nM). It prevents farnesylation of Ras GTPases and has shown potent efficacy in various in vitro and in vivo tumor models.Formal Name:...

Gliotoxin-13C13 is intended for use as an internal standard for the quantification of gliotoxin (Cay-11433) by GC- or LC-MS. Gliotoxin is an immunosuppressive mycotoxin produced by pathogenic strains of Aspergillus and other fungi with diverse biological activities. It inhibits 20S proteasomal chymotrypsin activity...

L-778,123 is a dual inhibitor of farnesyl transferase (FTase, IC50 = 2 nM) and geranylgeranyl transferase type I (GGTase I, IC50 = 98 nM). It inhibits prenylation of the FTase and GGTase I substrates HDJ2 and RAP1A in PSN-1 pancreatic tumor cells (EC50s = 92 and 6,760 nM, respectively). L-778,123 (1-300 µM) also...

FGTI-2734 is a C-terminal mimetic of Ras and a dual inhibitor of farnesyltransferase (FTase) and geranylgeranyl transferase type I (GGTase I, IC50s = 250 and 520 nM, respectively). It inhibits prenylation of H-Ras and Rap1A in oncogenic H-Ras-transformed NIH3T3 cells (IC50s = 88.7 and 2,700 nM, respectively)....

Description: GGTI298 Trifluoroacetate (GGTI 298 TFA salt) is a geranylgeranyltransferase I inhibitor with ability to arrest human tumor cells in the G1 phase of the cell cycle and induce apoptosis. Target: Apoptosis, Transferase, Ras. Smiles:...

Protein function: Essential subunit of both the farnesyltransferase and the geranylgeranyltransferase complex. Contributes to the transfer of a farnesyl or geranylgeranyl moiety from farnesyl or geranylgeranyl diphosphate to a cysteine at the fourth position from the C-terminus of several proteins having the...

Farnesylation involves the utilization of farnesyl pyrophosphate (FPP), an intermediate in the mevalonate pathway, by farnesyltransferase (FTase) to add a lipid, farnesyl, to certain proteins. This post-translational modification is crucial in allowing target proteins, including Ras, to associate with, and function...

FTase inhibitor I is a potent inhibitor of farnesyltransferase (FTase, IC50 = 21 nM) that is greater than 30-fold selective for FTase over geranylgeranyl transferase (GGTase, IC50 = 790 nM). It prevents farnesylation of Ras and inhibits proliferation of cells transformed by Ras farnesylation. In a dog model of...
