ANA-12
Chemical compound
From Wikipedia, the free encyclopedia
ANA-12 is a selective, small-molecule non-competitive antagonist of TrkB, the main receptor of brain-derived neurotrophic factor (BDNF).[1] ANA-12 was originally discovered and developed by Cazorla M. and colleagues at Université Paris and Inserm in 2011.[1] The compound crosses the blood-brain-barrier and exerts central TrkB blockade, producing effects as early as 30 minutes (~400 nM) and as long as 6 hours (~10 nM) following intraperitoneal injection in mice.[1] It blocks the neurotrophic actions of BDNF without compromising neuron survival.[1]

Research
ANA-12 has two binding sites on TrkB, a high- and low-affinity site (Kd = 10 nM and 12 μM, respectively).
ANA-12 produces rapid antidepressant- and anxiolytic-like effects in animal models,[1] the former of which have been elucidated to be mediated by blockade of BDNF signaling in the nucleus accumbens.[2][3] It has also been found to alleviate methamphetamine-induced depression-like behavior (including anhedonia), behavioral sensitization, and nucleus accumbens neuroplasticity changes with subchronic (14-day) administration in mice, whereas the TrkB agonist 7,8-dihydroxyflavone was ineffective in doing so.[4]
ANA-12 blocks the cognitive-enhancing effects of environmental enrichment and calorie restriction in rodents, which are mediated by BDNF signaling through TrkB in the hippocampus.[5][6] It also blocks hippocampal neurogenesis induced by physical exercise in rodents, and may block the cognitive-enhancing effects of exercise as well.[7]
