Hexa-D-arginine TFA (Furin Inhibitor II TFA) is a stable furin inhibitor with K_i values 106 nM, 580 nM and 13.2 μM for furin, PACE4 and prohormone convertase-1 (PC1), respectively. Hexa-D-arginine TFA blocks Pseudomonas exotoxin A and anthrax toxins toxicity in vitro and in vivo^[1][2][3].

Ki: 106 nM (Furin), 580 nM (PACE4) and 13.2 μM (PC1)^[3]

Hexa-D-arginine effectively blocks Pseudomonas aeruginosa exotoxin A (PEA)-induced cell lysis and is itself noncytotoxic^[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Administration of Hexa-D-arginine (0.1, 1, or 10 nM) to Pseudomonas aeruginosa exotoxin A (PEA)-treated mice (6-week-old FVB and 129/Sv mice) significantly improves their survival rate and also decreases circulating levels of TNF-α^[1].
