I saw a post on Twitter this week by some researchers who knew some of the original Montreal, Canada team that discovered rapamycin (and still have some of the original samples that were retrieved from easter island).
I thought that all of this is quite interesting given how famous rapamycin has now become, so I searched around to see if I could find the original 1975 paper that announced the discovery of rapamycin - and found it. So, I’ve included that below in case you too are interested.
There is a great podcast on the history and discovery of rapamycin that I highly recommend you listen to if you haven’t already:
Such an origin story for this drug.
I read there was a scientist who was wondering why the people of Rapa Nui didn’t get tentanus. That the horse population would lead to tentanus a lot more than occured. And they sampled the whole island in sections. I wonder where on the island the sample with rapamycin came from My bet is near an old shrine or temple or something
Wow! I just listened to the podcast.
So rapamycin is put ON the stents that they insert if you have a heart attack I’ll have to ask my uncle about that. I guess that means that these stents have a limited lifespan Well, hopefully after the embedded rapamycin wears off, you can just take the drug.
I mean isn’t that your clinical trial right there??
Hmm. I’ll have to quiz my uncle.
And that’s fascinating that Rapa Nui has the 2nd “small statue”.
But then, I’ve read they’ve carved “backs” onto the large ones too. I think the large and small statues sounds poetic and things. But I don’t think I’ll read too much into it.
I sure do wish I knew -where- on Rapa Nui that rapamycin came from. And how prevalent that microbe is in all soils. Scientists just don’t seem to be as smart as we think they are They’re just grasping for straws just like everyone else, seems to me.
Yes - disappointing in many ways regarding David Sabatini. I hope he learns from the experience and goes on to apply his knowledge in an mTOR focused startup company developing new drugs.
You learn something new everyday… Yesterday I learned a lot more about the original Canadian expedition to Easter Island that discovered the bacteria that produces the compound that has become famous as rapamycin.
For those interested - there is a book on the initial Canadian expedition (Initiated by researchers at McGill University in Montreal) to Easter Island. I found out about it from Laura Minquini’s article I link to on the home page.
I’ve gotten the book to read - and you can too, here:
The origin story of rapamycin: systemic bias in biomedical research and cold war politics
METEI (Medical Expedition to Easter Island) was a Canadian-led expedition to Easter Island in 1964 that led to the discovery of rapamycin, launching a billion-dollar drug industry and major field of biomedical research. Stanley’s Dream , by medical historian Jacalyn Duffin, provides remarkable details about METEI and raises important and timely questions about systemic bias in biomedical studies, the relationship between science and geopolitics, as well as obligations of pharmaceutical companies to indigenous communities. As such, this book is a must-read for those interested in the intersection of science and society as well as anyone who has used rapamycin, or one of many derivatives, in their laboratory or clinic.
My bet is near an old shrine or temple or something 
I’ll have to ask my uncle about that. I guess that means that these stents have a limited lifespan 
Well, hopefully after the embedded rapamycin wears off, you can just take the drug.
