Prior to 2015, I had a casual relationship, at best, with targeting RNA. The bulk of my nearly three decades of experience up to that point was with drugging protein targets using a variety of modalities, but principally smallmolecules. Welcome to the RNA world. Familiar tools to solve familiar problems with proteins.
A few years ago, at Arrakis Therapeutics, we set out to conquer a strange new territory, drugging RNA structures with smallmolecules. In fact, it was these early pharmaceutical successes that gave us the confidence that we would ultimately succeed in systematically drugging a wide range of RNA structures.
Metabolism of 2022 FDA approved smallmolecule drugs – Part 1 Does CYP3A4 still rule? By Julia Shanu-Wilson It won’t come as much surprise to learn that of the 17 smallmolecules* approved by the FDA in 2022, CYP3A4 was the major player in drug metabolism. References Iversen et al., Front Pharmacol.,
The majority of smallmolecule drugs induce their therapeutic effects by seeking out and binding to their intended target while avoiding most other molecules in the dense milieu of the cell interior. Our overall mission at Arrakis is to expand the set of “druggable” targets for small-molecule medicines to include RNA.
We are moving rapidly toward escape velocity in our RNA expedition at Arrakis. We want to mark this progress with some updates and perspectives in the Dark Matter blog. Our terra firma is small-molecule medicines. Our premise is that RNA is not fundamentally harder, it’s just different.
Since our company’s founding in 2015, we have taken the long view and been singularly focused on building an extremely flexible and broadly applicable platform that can develop a host of RNA‑targeted smallmolecules (rSMs) to deliver precision medicines for dozens of targets that have been out of reach for conventional approaches.
As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. My last stop at Arrakis Therapeutics is with a company targeting RNA with smallmolecules. Arrakis is the capstone of my career.
However, in June I happened to attend the Gordon Research Conference on Chemical Biology and High-throughput Chemistry where I saw a session on smallmolecules and RNA. Making small-molecule drugs against RNA structures looked like a really cool problem – I want to do THAT! This is a thing?
This approach is facilitated by developing ASOs and RNA interference (RNAi) therapies, which target the various molecular and genetic mechanisms contributing to ALS pathophysiology and disease progression. For a more in-depth discussion on challenges and solutions to ALS research, read our blog.
Or should I say back to retirement, as he was comfortably relaxing at home back in 2016 when Jen Petter lured him back into the fray with the siren call of developing a new class of RNA-targeted small-molecule medicines here at Arrakis. I won’t dwell on Jim’s many accomplishments here.
Most people, and in particular most investors we spoke to in those early days, thought we were nuts – that RNA lacked the structural and molecular complexity that medicinal chemistry exploits with such great effect for proteins. One is that molecular recognition is purely a matter of physics and RNA has to play by the same rules.
Read A new DNA polymerase variant, called RT-KTq I614Y, can directly detect RNA modifications, including pseudouridine (Ψ) and queuosine (Q). By combining this new variant with standard sequencing methods, it’s possible to identify RNA modifications in a really simple way. Nucleic Acids Research. Communications Biology.
The researchers first compared the editing efficiency of different versions of IscB when coupled with 'ωRNA,' which guides the enzyme to the right spot on the DNA. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome. Read more in Nature Methods.

The Druggable Genome The Druggable Genome is the subset of all human genes encoding proteins that could be targeted with a smallmolecule or antibody drug [4]. We then designed our own CRISPR guide RNA library against the druggable genome and transduced the corresponding lentiviruses into millions of our iNeurons.
In this blog article, we review some of these areas of investigation where Altasciences has robust expertise and solution offerings. Oligonucleotide-Based Techniques Most oligonucleotide therapies act through antisense mechanisms and are directed against various RNA species.
Read Ribosomes are able to build proteins because they contain a strand of RNA that imbues them with their catalytic power. Read An automated platform to make riboswitches (RNA strands that bind to smallmolecules and then quickly switch their structure) that can sense specific proteins. Synthetic Biology. Cell Systems.

Students learn the basics through words: DNA is transcribed to RNA, which is translated into proteins. How fast does DNA become RNA, or RNA protein? The other 30 percent is dominated by proteins first, followed by RNA and lipids. Let’s first think about DNA to RNA, or transcription. A typical E. A typical E.
