Researchers discover novel antifungal treatment

Fungal infections are claiming thousands of lives annually in the United States, with some strains having a nearly 80% morbidity rate. The problem is compounded by the limited availability and decreasing effectiveness of existing antifungal treatments, as fungi develop resistance. However, promising news emerges from the University of Oklahoma, where researchers have identified a potential breakthrough in the form of a novel treatment.

At the forefront of this discovery is Dr. Robert Cichewicz, a distinguished figure with extensive experience in fungal research. He and his team at the Natural Products Discovery Group have unveiled a compound named “persephacin,” which displays broad-spectrum antifungal activity while showing relative non-toxicity to human cells – a significant advantage compared to current treatments.

The surge in fungal infections can be attributed in part to the success in treating other medical conditions. As individuals live longer and benefit from treatments like chemotherapy and organ transplants, their immune systems often weaken. Coupled with drugs that suppress the immune system, such as those used for arthritis, a conducive environment for life-threatening fungal infections emerges.

This breakthrough hinges on the notion of endophytes – fungi that reside within plants and often help protect them from infections. The researchers theorized that if these plant-associated fungi could defend against invading pathogens, they might hold similar benefits for humans and animals. Their hypothesis proved correct, revealing the potential of these molecules in combating fungal diseases.

The research team devised an innovative method to extract leaf samples, utilizing a laser-based tool dubbed the Fast Laser-Enabled Endophyte Trapper (FLEET). This technique creates sterile samples at an impressive rate, significantly boosting the quantity of samples available for analysis.

Acknowledging the significance of their findings, Dr. Cichewicz, supported by the University of Oklahoma’s Office of Technology Commercialization, secured a U.S. patent for the use of persephacin in controlling infectious pathogens. With this achievement, the team’s focus turns toward collaborating with industry partners to further develop this promising treatment option.

In the face of evolving antifungal resistance, persephacin’s potential shines as a beacon of hope, offering a fresh alternative to address this pressing health concern.
