A recent breakthrough in pharmaceutical chemistry led by a Slovakian teenager may dramatically reshape how critical antiviral medications are produced—cutting costs, shortening timelines, and turning agricultural waste into life-saving therapies.
Adam Kovalčík, a 19-year-old from the rural village of Dulovce, Slovakia, earned international acclaim after developing a faster, significantly cheaper method of synthesizing galidesivir, a broad-spectrum antiviral drug used to treat RNA viruses such as Ebola, Zika, and SARS-CoV-2. His innovation, which centers on using corn husks as a raw material, won him the $100,000 George D. Yancopoulos Innovator Award at the 2025 Regeneron International Science and Engineering Fair (ISEF)—the world’s largest competition for pre-college scientific research.
A faster, lower-cost route to antiviral synthesis
Galidesivir, though potent and effective in targeting RNA-based viruses, is notoriously costly and slow to produce using conventional pathways—requiring 15 synthetic steps over the course of 9 days and costing approximately $75 per gram. Kovalčík’s method reduces the steps to 10, shortens production time to just 5 days, and brings down the cost per gram to only $12.
At the heart of this innovation is furfuryl alcohol, a compound derived from corn husks, which serves as a starting point for synthesizing aza-saccharide—a key intermediate in galidesivir production. By reengineering the synthetic pathway, Kovalčík significantly streamlined the conversion process.
“He was able to shortcut this entire process,” explained Chris RoDee, a retired patent examiner and chemistry expert who served as a judge at ISEF. “He basically halved the number of steps because he just went in through a different door.”
This revised pathway not only improves efficiency, but also aligns with sustainable chemistry practices by utilizing agricultural waste—an abundant, low-cost feedstock often discarded in commercial corn production. According to U.S. Department of Agriculture data, corn residues like husks and stalks represent a significant, untapped resource for bio-based applications.
A “bulletproof” presentation from a young innovator
Competing against thousands of students from around the globe at the Regeneron ISEF in Ohio, Kovalčík’s presentation stood out not only for its scientific merit but also for its clarity and rigor. Judges praised the work as “bulletproof”—a rare level of validation in such a competitive forum.
“I cannot describe this feeling,” Kovalčík told Business Insider. “I did not expect such a huge international competition to be won by someone from a small village in a small European country, so it was just pure shock.”
The promising young chemist has already filed a preliminary patent for his novel process and intends to collaborate with a research group at the Slovak University of Technology in Bratislava to refine and scale the method further.
In an impressive display of both scientific and entrepreneurial foresight, Kovalčík also revealed plans to launch a start-up focused on creating eco-friendly perfumes made from corn derivatives—another application of his interest in sustainable bio-chemistry.
Implications for global health access and green chemistry
While Kovalčík’s innovation is still in the early stages of commercialization, it highlights an important shift in pharmaceutical manufacturing—toward greener, decentralized, and cost-effective production. The use of renewable raw materials such as corn husks supports global goals for sustainable chemistry as outlined by organizations like the American Chemical Society (ACS) and the United Nations Environment Programme.
If further validated and adopted at scale, Kovalčík’s approach could help democratize access to vital antivirals, especially in low- and middle-income regions where pharmaceutical infrastructure and procurement costs remain significant barriers.
Moreover, the use of bio-waste in drug synthesis introduces important environmental benefits by reducing reliance on petroleum-derived feedstocks and minimizing chemical waste—aligning with the principles of atom economy and cradle-to-cradle resource utilization.
A model for young researchers and bio-based innovation
Kovalčík’s success serves as an inspirational case study of youth-led scientific advancement intersecting with real-world application. His ability to reimagine a complex chemical process using locally available, sustainable materials is emblematic of a new generation of researchers who are both academically rigorous and socially conscious.
As this innovation progresses from science fair triumph to industrial potential, it may very well mark a pivotal step toward more resilient and sustainable pharmaceutical manufacturing.
