New Solutions in Neuropsychiatry

• Context: PTSD, MDD, anxiety driven by deficits in brain circuitry underlying emotional learning and processing^1,2
• TSND-201 rapidly induces neuroplasticity gene expression (e.g., BDNF) in brain areas underlying pathophysiology of PTSD, depression, and anxiety^3,4,5
• Collaborative grant ($1M from US DoD) with leading Yale scientists awarded to support further work on neuroplasticity MoA

• Triple reuptake inhibitor and releaser (serotonin, norepinephrine, dopamine)
• Rapid, robust serotonin and norepinephrine release in frontal cortex of the brain⁸
• No off-target toxicity expected, as no agonism or antagonism at 168 GCPRs⁷
