ADWX 1 TFA
Based on 1 publication(s) in Google Scholar
ADWX 1 TFA is a new peptide inhibitor that is potent and selective for Kv1.3 with an IC50 value of 1.89 pM. ADWX 1 inhibits Kv1.3 channel activity specifically to inhibit both the initial calcium signaling and NF-κB activation. ADWX 1 TFA ameliorates the disease in rats of experimental autoimmune encephalomyelitis (EAE) models. ADWX 1 TFA can be used to study T cell-mediated autoimmune diseases.

Kv1.3 1.89 pM (IC50) |
Kv1.1 0.65 nM (IC50) |
ADWX 1 (1,10 nM, 1 h) TFA inhibits IL-2 and IFN-γ productions, and inhibits humans CD4+ CCR7- TEM cells activation selectively[2].
ADWX 1 (1,10 nM, 50 min) TFA reduces [Ca2+] in activated CD4+ CCR7- TCM cells from EAE rats[2].
ADWX 1 (1,10 nM, 1 h) TFA reduces NF-κB activation and suppresses Kv1.3 expression at both mRNA and protein levels preferentially in myelin basic protein (MBP) (HY-P77995)-stimulated CD4+ CCR7- T cells from EAE rats[2].
ADWX 1 (1,10 nM, 3 days) TFA suppresses Th17 activation but not differentiation in CD4+ CCR7- T cells[2].
