Biochem/physiol Actions

Cyclotraxin-B is a potent and selective Trk B (BDNF/NT-3) receptor inhibitor. Cyclotraxin-B prevents receptor activation by BDNF without interfering with BDNF binding. Cyclotraxin-B has an IC50 value < 1 nM. In rodent studies Cyclotraxin-B, sometimes fused with tat-protein for increased brain permeability, has been shown to have anxiolytic properties, prevent cold hypersensitivity induced by BDNF, and to reduce cocaine self-administration.
