Rick Pierce, Co-Founder and CEO of Decoy Therapeutics. is using AI and machine learning to accelerate drug discovery and is developing broad-acting antivirals using peptide conjugates that target a shared invasion mechanism of hundreds of viruses.  The company is using small language models and a high-speed peptide synthesizer to dramatically reduce drug creation time. Rick predicts that the future of drug discovery will combine AI-driven design with advanced biological models, such as organoids, to better predict drug toxicity and efficacy.

Rick explains, "Decoy Therapeutics was founded years ago, during the COVID era. And what we've learned during that was that in order to develop drugs rapidly and scale up their manufacturing, we needed to use machine learning and AI. And the drugs that we're looking at developing today as a result of that are broad-acting antivirals that can be used against multiple viruses. So one drug can be used against multiple viruses like Flu, COVID, and RSV."

"So we chose antivirals as a space because viruses have what is called polypharmacology, and in plain layman's terms, what that means is that about 250 of these viruses share the same invasion machinery, meaning the way the virus enters the healthy cells is shared across all those viruses. It's slightly different in each of those viruses, but effectively for drug development, very similar."  

"That allows us to use peptides, which are also alpha helices, to be able to design drugs with AI and machine learning that physically block the invasion machinery and thus basically the virus from binding to a healthy cell. Peptides are uniquely positioned as drugs for this set of viral targets. Again, it's a rich set of targets among 250 viruses across multiple viral families."
