This is really fascinating to me. I'd be really curious to know how many steps (& what yield) that the actual plant needs to do this & how each one evolved. I'd also like to know if any insects, or larger organisms, have managed to adapt to process the toxic stuff, enabling their consumption of the plant.

Strychnine was an important and effective heart medicine even in the 20th century. When we cleaned out my late grandparents' old house, a box of my grandfather's strychnine pills from 1930s was found. If my memory is correct, each pill contained 1/30th of a grain of strychnine.

Best story i ever heard about it was that Woodward, at some frustrating point in his attempt to synthesise it, was reputed to have said "we'll either make it or I'll take it".

Absolutely amazing, the 1000 fold improvement on total synthesis in 55 years.. The attention to detail here on the chemical of the day has my vote as number one science channel on the web. Brilliance. Anyone feel like guessing the starting material? And no cheating! My first guess would be Tryptamine.

That is a fantastic video. I am a neuroscientist, and I've never heard or read a more clear elucidation of chemistry than this one. - "In truth, it is just atoms and the void."

very cool story about the synthesis, I'm so lucky to know about this youtube channel!

Very interesting thanks for the information

A slight correction: because of its effects on the receptors strychnine IS a PNS stimulant, so it is a marginally effective as an athletic enhancer, muscles contract more forcefully. The problem is that the theraputic index is razor sharp. A report from a student that suffered a mild intoxication while using it as a stimulant attest to its effects at slightly supra-theraputic doses, even after he sedated himself with bromide.

What a nice coinkydink.. I listened to the Sonics song Strychnine just about an hour ago!. "Some folks like water, some folks like wine, but I like the taste of straight strychnine"

Fantastic video. One thing I feel sometimes is missing though is any discussion about actual use cases in the modern world of the chemicals being discussed. For instance, the synthesis of the chemical was carried on in the '90s and into the modern day, but what was the incentive for doing that? Simply to refine a process that could be applied to other chemicals of a similar kind or is there a industrial application to be had from being able to make Strychnine on a 'mass' scale?

If they haven't already got a video about mercuric sulphide (cinnabar) and alchemy, I'd like to see that. If they've already done that & I just didn't know, my second idea is about either benzene or sodium polyacrylate.

One of my favourite songs is Strychnine by The Sonics.
