Researchers achieve total synthesis of ibogaine to enable efficient access to ibogaine analogs for studying therapeutic properties

Ibogaine total synthesis enables researchers to access ibogaine and related alkaloids without relying on harvesting limited plant sources. A UC Davis team reported an efficient modular route to synthesize ibogaine, multiple ibogaine analogues, and related compounds starting from pyridine. The strategy produced several naturally occurring alkaloids and non-natural analogues with overall yields reported as 6% to 29% after about six to seven steps. The work aims to support safer drug discovery by making larger-scale study of ibogaine and improved “ibogaine 2.0” possible, addressing known concerns like irregular heartbeats. Experiments highlighted specific analogues: a mirror-image form suggested receptor-specific biology for neuronal growth, and (-)-10-fluoroibogamine showed strong effects on neuronal structure and serotonin transporters, motivating further investigation for substance use disorders and depression.
