B581 Chemical Properties,Usage,Production

Description

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 subarachnoid hemorrhage, it reduces GTP-Ras in spastic basilar arteries, decreases angiographic vasospasm, and improves clinical scores.

Uses

FTase Inhibitor I is a potent, selective, peptidomimetic FTase inhibitor.

Definition

ChEBI: A dipeptide obtained from the tetrapeptide Cys-Val-Phe-Met by reduction of the amide carbonyl groups of the Cys and Val residues.

Enzyme inhibitor

This cell-permeable CAAX peptidomimetic (FW = 470.70 g/mol; FWtrifluoracetate-salt = 583.71 g/mol; CAS 149759-96-6), named as N-[2(S)- (2(R)-2-amino-3-mercaptopropylamino)-3-methylbutyl]-L-phenylalanyl-L methionine), binds to and prevents protein farnesyltransferase (IC50 = 21 nM) from interacting with C-terminal L-Cys-L-Val-L-Phe-L-Met substrate recognition sequences that are present in its natural substrates. Otherwise hydrophilic proteins associate with membranes by means of enzymatic attachment of hydrophobic moieties to their C-termini. Whereas prenylation occurs in the cytosol, post-prenylation processing is accomplished on the cytoplasmic surface of the endoplasmic reticulum and Golgi apparatus. B581 inhibits prenylation and processing of H-ras and lamin A. B581 specifically blocks farnesylated, but not geranylgeranylated or myristylated, oncogenic ras signaling and transformation.
