Inside Patricia Musacchio's chemistry lab at the University at Buffalo, small blue lights glow on shelves lined with clear boxes the team calls "Buffalo boxes." These aren't special lab equipment — they're the same LEDs used to grow herbs in kitchens and light up home aquariums. And they might just be the future of faster, cheaper drug development.
Musacchio and her team have discovered a simpler way to build complex drug molecules using these everyday blue lights. Their method, published in the journal Science, allows chemists to make two changes to a molecule's structure in a single reaction — something that previously required two separate steps. For drug developers racing to create new medicines, that difference could shave months off the timeline.
"The advantage is getting two modifications from a single reaction, whereas you normally only get one modification," said Jennifer Hirschi, an associate professor of chemistry at Binghamton University who co-led the study. "More changes in fewer steps is crucial when creating small-molecule drugs."
The secret lies in a light-activated catalyst mixed with familiar chemical building blocks that chemistry students learn about in their second year of college. When the blue LEDs shine on the solution, the catalyst temporarily transforms the molecules into a more reactive form, allowing chemists to modify two neighboring carbon atoms instead of one. Carbon atoms form the backbone of most small-molecule drugs, so being able to reshape them more efficiently is a big deal.
Traditional methods often use high-energy ultraviolet light, which can break down the very molecules researchers are trying to create. The blue LEDs offer a gentler approach that preserves the molecules while still getting the job done.
The research was a collaboration between the University at Buffalo, where Musacchio is an assistant professor of chemistry, and Binghamton University, where Hirschi works. It was supported by the National Institutes of Health and the National Science Foundation.
Looking ahead, the team plans to partner with pharmaceutical companies to explore how this method could be adapted for real-world drug development. Musacchio hopes the technique will eventually be expanded to other types of molecular transformations.
"The hope is to not only make drugs faster, but also make more complex drugs that can target more challenging medicinal goals," she said.
