      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.

    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.

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?

    Collective synthesis of natural products by means of organocascade catalysis is the name of the mcmillian paper if you are interested, though i needed to use an institutional access to get hold of it

    Please produce some videos on the instruments used in chemical analysis and how chemical structure is deduced. It would also be interesting to see something on named reactions.

    I ACTUALLY have an old antique medicine bottle, never opened, that contains strychnine! Including arsenic! They're 100 chocolate-coated tablets. Iron (1 grain), arsenous acid (1/50 grain), and strychnine sulphate (1/60 grain). Parke-Davis Drug Company. I wish I had a picture. Too bad you can't put pics in comments. It's crazy that I found a bottle of strychnine (with arsenic) containing "medicine". Awesome video!

    As far as I know, strychnine doesn't prevent muscle contraction, it prevents the relaxing

    Just thought of something, could you guys do a video at some point about how to determine a molecule's structure?
    Especially the "old-fashioned" way that the they had to use back in the day (since that one probably is less complex to understand).

    Speaking about rat poison, it would be cool to see a video about Warfarin. An interesting piece of historical trivia is that the discoverer, Frank Schofield, was both a veterinarian and a major figure in the liberation of Korea from the Japanese Empire (a story most Ontario Veterinary College graduates have heard several times).

    Two new syntheses of strychnine were very recently published which consist of 10 steps with a 14% yield and 8 steps with a 10% overall yield! Exciting stuff. Beemelmanns et al, July 29 2015, in The Chemical Record
