With new funding, Atomic AI envisions RNA as the following frontier in drug discovery • TechCrunch

The biotech business is experiencing a rush of AI-powered instruments for a lot of points of the advanced drug discovery course of. However one which has flown beneath the radar, more and more regarded as key to sure illnesses however woefully understudied, is RNA. With $35 million in new funding, Atomic AI goals to do for RNA what AlphaFold did for proteins, and discover solely new remedies within the course of.

If you happen to can nonetheless recall your highschool biology, you in all probability bear in mind RNA as kind of a center man between DNA (long run info storage) and proteins (the equipment of mobile life on the molecular degree). However like most issues in nature, it doesn’t appear to be fairly that easy, defined Atomic AI’s CEO and founder, Raphael Townshend.

“There’s this central dogma that DNA goes to RNA, which fits to proteins. Nevertheless it’s emerged in recent times that it does rather more than simply encode info,” he mentioned in an interview with TechCrunch. “If you happen to take a look at the human genome, about 2% turns into protein sooner or later. However 80 p.c turns into RNA. And it’s doing… who is aware of what? It’s vastly underexplored.”

In comparison with DNA and proteins, little work has been completed on this space. Academia has targeted on different items of the puzzle and prescription drugs have, partly as a consequence of that, pursued proteins because the mechanisms for medication. The result’s a extreme lack of expertise and information on RNA buildings.

However what Atomic AI posits is that RNA is useful and value pursuing as a way of therapy. The key is within the “non-coding” areas of RNA, that are just like the header and footer on a doc. They do protein-like work however aren’t proteins — they usually’re not the one instance.

You possibly can take into consideration RNA strands as beaded necklaces, rather more string than bead. The string is “floppy” and kind of what its detractors assume it’s: an middleman. However each from time to time you get a extremely fascinating knot that appears unlikely to have fashioned by chance. As with proteins, in the event you can work out their construction, that goes a great distance in the direction of understanding what they do and the way they are often affected.

“The secret is to search out these beads, these structured bits. It’s excessive info content material, it’s targetable, and it’s probably useful as nicely,” mentioned Townshend. “It’s seen in drug discovery as a key new frontier.”

An fascinating concept for a graduate thesis, maybe (and it was for Townshend), however how are you going to construct a enterprise round it?

First, if the sphere is about to turn into extra necessary, constructing out the strategies for finding out has quite a lot of worth. Then, in the event you do construct these strategies, you could be first in line to make use of them. Atomic AI is doing each concurrently.

The core of Atomic’s IP is, although that is one thing of a simplification, an AlphaFold for RNA. The biology is totally different, and the way in which the fashions work is totally different, however the concept is similar: a machine studying mannequin skilled on a restricted set of a sort of molecule that may make correct predictions in regards to the construction of different molecules of that kind.

What’s wild is that Townshend’s group made simply such a mannequin, which outperforms others by a big margin, by feeding it the traits of simply 18 RNA molecule buildings “revealed between 1994 and 2006.” This positively bare-bones mannequin wiped the ground with others, as disclosed in a front-page article revealed in Science in 2021.

Since then, Townshend was fast so as to add, the corporate has vastly augmented its fashions and strategies with extra uncooked materials, a lot of which it has created itself in its personal moist labs. They name the up to date set of instruments PARSE: Platform for AI-driven RNA Construction Exploration.

“The Science paper represented an preliminary breakthrough, however we’ve really generated an enormous quantity of… structure-adjoining information,” he defined. “Not the total construction itself, however information associated to the construction, tens of hundreds of thousands information factors; the identical scale of information you’d want to coach massive language fashions. And mixed with different machine studying work, we’ve been in a position to dramatically enhance each the velocity and accuracy from the paper.”

Meaning Atomic AI is the one one who, publicly no less than, has a system that may take a RNA molecule’s uncooked information in and spit out a fairly assured estimate of its construction. That’s helpful to anybody doing RNA analysis in or out of drugs, and with gene therapies and mRNA vaccines, the sphere is certainly on the rise.

With such a software you could possibly go one in all two methods: license it as a “construction as a service” platform, as Townshend put it, or use it your self. Atomic has opted for the latter, and is pursuing its personal drug discovery program.

This strategy has a notable distinction from quite a lot of the AI discovery processes on the market. The final concept is you’ve got a protein, say one you wish to inhibit expression of within the human physique, however what you don’t have is a chemical that binds reliably and completely to that protein, precisely the place and if you need it to (and cheaply, if doable).

AI drug discovery efforts have a tendency to provide 1000’s, hundreds of thousands, even billions of candidate molecules that would possibly work, rank them, and let the moist labs begin working by the listing as quick as they will. If you’ll find one which meets these above traits, you’ll be able to produce a novel drug or exchange a dearer one available on the market. However the important thing factor is you’re competing to search out new binders to a identified protein.

“We’re not simply discovering binders, we’re discovering what’s targetable within the first place. The rationale that’s fascinating is as a result of on the finish of the day, these massive prescription drugs care extra about novel biology than novel molecules. You’re enabling one thing that wasn’t doable earlier than by discovering this new goal, versus augmenting the variety of molecules accessible to focus on it,” mentioned Townshend.

Not solely that, however some proteins have been discovered to be nigh undruggable for no matter purpose, producing sicknesses proof against treatment. RNA may enable therapy of those identical sicknesses by making an finish run round the issue protein.

For the current, Atomic AI has narrowed down the listing to sure cancers that lead to pathological overproduction of proteins (and therefore good choices for preempting the mechanism), and neurodegenerative illnesses which will additionally profit from upstream intervention.

In fact all this work is immensely expensive, necessitating because it does a considerable amount of each lab work and intense information science. Thankfully the corporate has raised a $35 million A spherical, led by Playground International, with participation from 8VC, Manufacturing facility HQ, Greylock, NotBoring, AME Cloud Ventures, in addition to angels Nat Friedman, Doug Mohr, Neal Khosla, and Patrick Hsu. (The corporate beforehand raised a $7 million seed spherical.)

“Folks have picked all of the low-hanging fruit in protein land,” mentioned Townshend. “Now there’s new biology to go after.”
