Biological Activity
Dalazatide (ShK-186) (0-1000 pM) blocks the Kv1.3 current in the Ova-specific GFP+ effector memory T (Tem) cells in a dose-dependent manner with a Kd of 65 ± 5 pM[3].
Dalazatide (0-100 nM; 3 days) inhibits CCR7− T cell proliferation in a dose-dependent manner[3].
Dalazatide (100 nM; 30 min) immobilizes effector memory T (Tem) cells at inflammatory sites by suppressing calcium signaling and thereby preventing β1 integrin activation[3].
