Of the classic psychedelics, lysergic acid diethylamide (LSD) is perhaps the best-known, but its complex chemical architecture has limited synthetic investigations aimed at generating analogues with improved safety and efficacy profiles. Here, we systematically deconstruct the tetracyclic ergoline core of LSD to create 9 simplified ergoline analogues (i.e., ergologs) and evaluate them in...

The serotonin 2A receptor (5-HT2AR) modulates various neurotransmitter systems and is implicated in psychiatric disorders, including depression and schizophrenia. Despite progress, the detailed mechanisms of signaling at the 5-HT2AR and its therapeutic implications remain unclear, warranting further exploration. Overcoming the limitations of conventional pharmacology, photopharmacology...

Decreased dendritic spine density in the cortex is a key pathological feature of neuropsychiatric diseases including depression, addiction, and schizophrenia (SCZ). Psychedelics possess a remarkable ability to promote cortical neuron growth and increase spine density; however, these compounds are contraindicated for patients with SCZ or a family history of psychosis. Here, we report the...

Anecdotal reports and preliminary clinical trials suggest that the psychoactive alkaloid ibogaine and its active metabolite noribogaine have powerful anti-addictive properties, producing long-lasting therapeutic effects across a range of substance use disorders and co-occurring neuropsychiatric diseases such as depression and post-traumatic stress disorder. Here we report a gram-scale,...

Decreased dendritic spine density in the cortex is a hallmark of several neuropsychiatric diseases, and the ability to promote cortical neuron growth has been hypothesized to underlie the rapid and sustained therapeutic effects of psychedelics. Activation of 5-hydroxytryptamine (serotonin) 2A receptors (5-HT2ARs) is essential for psychedelic-induced cortical plasticity, but it is currently...
