First PROTAC wins FDA approval.

To do this, they wanted to make a chemical with two faces one that bound the quality control system and one that bound the protein they wanted to destroy. Both are difficult chemistries to build.
But the work on thalidomide revealed a ready made chemical that bound the quality control system, this spurred a whole ton of academic and biotech research that is just now bearing its first fruits.

What is so exciting about PROTACs is they can be designed to destroy almost protein, so their usefulness isn’t limited to cancer therapies, there are PROTACs in the works for neurodegenerative diseases and autoimmunity.
It’s really an amazing time to be in bioscience (there’s bad stuff happening to the scientific enterprise esp in the US but I’ll leave this thread mainly positive)

First PROTAC wins FDA approval. This one targets certain metastatic breast cancers.
This is the first of a totally new type of drug that is set to revolutionize drug development.
The story of PROTACs is fascinating and a testament to fundamental research.
It starts with two lines of research including research one why thalidomide causes birth defects the other on how to harness cellular machinery for therapeutics.

@MCDuncanLab thanks for this thread!
I’m hoping i didn’t get some small details wrong, I’m partly working from memory partly from references some of which I’m only accessing the free content since I’m not at work.
Will update if I find mistakes.

Funny related story. When I was a postdoc, I wanted a quicker way to inhibit the protein I was studying. We had been using something called temperature sensitive mutations, which were slow or we could have used a regulated promoter, which was also slow.

I came up with this amazing idea of using the cell quality control system to rapidly destroy my protein. I was super excited and I talked to somebody who worked on the quality control system, and shared my idea.
She asked so like the system that Ray Deshaise is working on? And I realized that I had seen a talk a year or two earlier where Ray had described the system and I had forgotten it and taken it as my own idea.

No harm done I hadn’t put his idea as my own at least in writing. And I came up with my own approach and I identified a small molecule inhibitor of my process. This let me getting my faculty job, but I don’t work on small molecules anymore. It was a fun time.

@MCDuncanLab Oh my god, if we could send them after prions!!!

That’s one target of interest.

just me
all the greats take in ideas and then a few months later think it is their ideaso you are in great company !!
this is based on two years as a postdoc at MIT biology; YMMV

Well I am reaching the stage in my career where I expect that 10 years ago me will be scooping today me.
