#116 Meet The World’s Greatest Psychedelic Receptor Scientist

Bryan L. Roth is a drug receptor scientist who solved the crystal structure of LSD inside a serotonin receptor and took $26.9 million from DARPA to build a non-hallucinogenic psychedelic — a compound that hits the same receptor as psilocybin, produces antidepressant effects in mice, and doesn't cause a trip.Expect to learn how his mother's schizophrenia launched a 40-year career in pharmacology, why Salvia divinorum has zero serotonin activity and works entirely through the kappa opioid receptor, why serotonin and opioid receptors converge in the claustrum, why DARPA funded non-hallucinogenic alternatives for soldiers, how his lab screens a trillion compounds that don't physically exist, why only 100 of 26,000 protein targets have ever been drugged, and much more…Timestamps: 00:00 Bryan L.
