一种一种选择性 TrkB 拮抗剂,对高亲和位点和低亲和位点的Kd 分别为10 nM 和 12 μM。ANA-12 is a TrkB ligand that prevents activation of the receptor by BDNF with a high potency. It binds selectively to TrkB and inhibits processes downstream of TrkB without altering TrkA and TrkC functions. In adult mice model ANA-12 decreases TrkB activity in the brain without affecting neuronal survival. Mice dosed with ANA-12 show reduced anxiety- and depression related behaviors on a variety of tests predictive of anxiolytic and antidepressant properties in humans. ANA-12 may be a valuable tool for studying BDNF/TrkB signaling and may constitute a lead compound for developing the next generation of therapeutic agents for the treatment of mood disorders. There is also N-T19, which is less potent.
