Innovating on the intersection of chemistry, biology, and engineering, Professor Brad Pentelute and the Pentelute Lab at MIT invent new chemistry, platforms, and strategies that may revolutionize therapeutics. Their components in short: nature-inspired analysis that begins on the molecular stage, infused with state-of-the-art machine studying and automation, aimed toward fixing real-world issues.
Take, for instance, biotechnology’s longstanding protein supply downside. Efficient intracellular protein supply has huge potential for enhancing human well being and curing illness. The important thing problem is delivering massive molecules (e.g., peptides, proteins, and oligonucleotides) into cells.
Pentelute and his group of researchers determined to see what they may be taught from nature’s supply programs for big molecules. Extra particularly, they investigated anthrax. The lethal toxin occurs to be superb at inserting proteins into cells, explains Pentelute, whose postdoctoral work at Harvard Medical Faculty checked out how infectious brokers infiltrate cells on the molecular stage.

Pentelute and his group modified the lethal toxin right into a car for delivering antibody and peptide variants that can be utilized to deal with most cancers. As Pentelute explains, “We basically hijack the anthrax supply system to get proteins into the cell. Our discovery will considerably support within the growth of sturdy cell-based protein therapeutics.”
In the meantime, he has spent 12 years constructing an automatic protein printing machine, which began in collaboration with MIT Professor Klaus Jensen. Their innovation borrows its design from nature’s ribosome, which stitches collectively amino acids to create proteins in simply minutes. And whereas their human-made model shouldn’t be as quick as its inspiration — not but, anyway, in response to Pentelute — it does assist to speed up the scientific experiment and drug discovery course of.
“We’ve constructed the world’s quickest and most effective machine of its sort; it’s able to producing hundreds of amide bonds an order of magnitude sooner than commercially out there devices,” says Pentelute. Which means it would simply speed up the manufacturing of on-demand customized therapies like most cancers vaccines. Thus far, the platform is utilized by labs throughout MIT’s campus. Additionally it is the premise for Amide Applied sciences, a startup Pentelute helped launch to scale his creation.
He and his group at MIT have constructed different platforms, too, together with one which discovers new biologically energetic peptides and proteins able to disrupting the unfold of most cancers. Based mostly on affinity choice mass spectrometry, Pentelute says their invention proved notably helpful on the peak of the Covid-19 pandemic. It allowed them to be among the many first to find quite a few peptidomimetics that may bind to the ACE2 receptor, which is critical for SARS-CoV-2 to enter cells. Additionally they found a number of the first peptides that bind to the coronavirus spike protein.
These discoveries led Pentelute and his group to the conclusion that they had been constructing a speedy response platform that, as Pentelute places it, “can take a look at a protein or some biology of curiosity and quickly establish new ligands, new binders that would finally be used both for assays or potential beginning factors for medication.”

Based mostly on the know-how, Pentelute helped launch a pharmaceutical startup referred to as Decoy Therapeutics. Pentelute says, “Right this moment, Decoy is working to construct a nasal formulation primarily based on a peptide that we have designed that may inhibit viral development and transmission. We’re testing that proper now, and it seems fairly thrilling.”
As well-versed as he’s in translating concepts from the lab to the actual world, it’s no shock that Pentelute credit trade needs and wishes as an essential driver of innovation in his analysis program. Additionally it is why he believes the MIT Industrial Liaison Program (MIT ILP), nicely established as trade’s most complete portal to the Institute, is an important facet of the MIT innovation ecosystem. “MIT ILP has been an outstanding associate to my lab,” he says. “We’ve put collectively a minimum of 10 sponsored analysis agreements that began with the ILP introductions. It is a good way to community, join, and check out new approaches to problem-solving.”
Ask Pentelute about the way forward for his analysis, and he’ll let you know he and his group are exhausting at work producing molecular knowledge to ascertain programs able to coaching algorithms to design molecules with new features. In reference to the work, he says, “We had been the primary folks on the planet to make use of machine studying to design miniature abiotic (not designed by nature) cell-penetrating proteins.”
One among their collaborators on the brand new mission is Professor Manolis Kellis of the MIT Pc Science and Synthetic Intelligence Laboratory. Kellis is well-known for his groundbreaking work exploring genome-level adjustments as causal drivers of illness. “We’re constructing information timber to know what’s driving, as an example, weight problems,” Pentelute explains, “after which we will come over to my laboratory and determine learn how to quickly make and take a look at these molecules.”
Becoming a member of the MIT professors of their endeavor is Harvard Medical Faculty’s Marinka Zitnik. She is on the forefront of constructing the Therapeutic Knowledge Commons, which gathers knowledge to construct machine studying fashions to speed up drug growth. “With Marinka’s assist, earlier than we do experiments, we are able to ask questions on how a molecule, given its specific design, would possibly work inside a human,” says Pentelute.
“This can be a important second by way of the way in which we do science,” says Pentelute. “We’re converging to construct a brand new paradigm of pondering by means of the AI-driven design of molecules to work together with people. Sooner or later, we’ll be capable of design molecules as wanted to influence not simply human well being, however all the pieces that we expertise right here on earth. We’re leapfrogging into a brand new house of innovation — that’s what drives me, and that is what we’re attempting to construct right here on the Pentelute Lab.”
