Biological Activity for BIBN 4096

BIBN 4096 is a potent and selective CGRP receptor antagonist (IC50 values are 0.03 and 6.4 nM for human and rat CGRP receptors respectively). Displays high affinity for human CGRP receptors (Ki = 14.4 pM); exhibits no significant affinity for 75 other receptors. BIBN 4096 improves pain symptoms in a mouse migraine model.
