Synthetic iboga alkaloid congener

The ibogaine research team at Albany Medical College has developed a synthetic iboga alkaloid congener, 18-methoxycoronaridine (18-MC). Animal research shows that 18-MC shares ibogaine's anti-addictive properties, possibly without ibogaine's hallucinogenic effects, possibly not. View the molecular structure at bottom of page.

The most recent research indicates that 18-MC may have anti-HIV activity thus providing a very interesting perspective as a medication capable of treating two vector related disorders: Chemical dependence and HIV. We now await the testing of ibogaine and other iboga alkaloids and congeners to determine if they may also have such broad spectrum activity and to what degree.
