Tat-CBD3A6K (trifluoroacetate salt)

Tat-CBD3A6K is a peptide and derivative of the N-type voltage-gated calcium channel Cav2.2 and collapsin response mediator protein 2 (CRMP2) protein-protein interaction inhibitor Tat-CBD3 (Cay-37448). Tat-CBD3A6K (10 mg/kg) prevents decreases in the paw withdrawal threshold in a rat model of antiretroviral neuropathic pain induced by d4T (stavudine, Cay-14975) and decreases the number of action potentials from dorsal root ganglia (DRG) neurons isolated from the same rats. Dural administration of Tat-CBD3A6K (30 µM/animal) decreases meningeal blood flow induced by the terpene alkaloid capsaicin (Cay-92350, Cay-10010743) in rats.Formal Name: L-tyrosylglycyl-L-arginyl-L-lysyl-L-lysyl-L-arginyl-L-arginyl-L-glutaminyl-L-arginyl-L-arginyl-L-arginyl-L-alanyl-L-arginyl-L-seryl-L-arginyl-L-leucyl-L-lysyl-L-alpha-glutamyl-L-leucyl-L-arginylglycyl-L-valyl-L-prolyl-L-arginylglycyl-L-leucine, trifluoroacetate salt.
