Description
Decanoyl-RVKR-CMK is a subtilisin/Kex2p-like proprotein convertase inhibitor which blocks the activity of all seven convertases, PC1, PC2, PC4, PACE4, PC5, PC7 and furin. Proprotein convertases are involved in generating bioactive peptides and activating several enzymes and growth factors in many physiological events so have important roles in some pathologies including viral infections and cancer. Decanoyl-RVKR-CMK abolishes proET-1 processing in endothelial cells and inhibits regulated secretion of the neuronal polypeptide VGF. Decanoyl-RVKR-CMK can also inhibit cleavage of the SARS-CoV-2 spike protein by furin and blocks viral cell entry with an IC50 of 57 nM in a plaque reduction assay.

About TFA salt
Trifluoroacetic acid (TFA) has a significant impact on peptides due to its role in the peptide synthesis process.
TFA is essential for the protonation of peptides that lack basic amino acids such as Arginine (Arg), Histidine (His), and Lysine (Lys), or ones that have blocked N-termini. As a result, peptides often contain TFA salts in the final product.
TFA residues, when present in custom peptides, can cause unpredictable fluctuations in experimental data. At a nanomolar (nM) level, TFA can influence cell experiments, hindering cell growth at low concentrations (as low as 10 nM) and promoting it at higher doses (0.5–7.0 mM). It can also serve as an allosteric regulator on the GlyR of glycine receptors, thereby increasing receptor activity at lower glycine concentrations.
In an in vivo setting, TFA can trifluoroacetylate amino groups in proteins and phospholipids, inducing potentially unwanted antibody responses. Moreover, TFA can impact structure studies as it affects spectrum absorption.
