Researchers at the University of Georgia (UGA), David Chu and Uma Singh, have made a groundbreaking discovery that could transform how we treat certain viral infections.
They have developed a new molecule, POM-L-BHDU, which shows great promise in treating the varicella zoster virus, the cause of chickenpox and shingles.
It could also help combat herpes simplex viruses, which cause oral and genital herpes. This discovery brings hope to millions of people affected by these conditions worldwide.
The varicella zoster virus is a tricky pathogen. After causing chickenpox, it remains dormant in the body for years. For some, it reactivates later in life as shingles, a condition that causes severe pain and discomfort, especially in older adults.
Meanwhile, herpes simplex viruses 1 and 2 cause oral and genital herpes. These conditions are not only painful but also carry a social stigma and can have a significant emotional impact on those affected.
The new molecule, POM-L-BHDU, is unique because of its safety and versatility. Unlike many existing treatments, it can be used in various ways—taken orally, given as an injection, or applied directly to the skin as a cream.
Its potential as a topical treatment is particularly exciting. When applied to the skin, it targets the virus at the source, reducing the chance of it spreading while minimizing the drug’s presence in the bloodstream.
This localized treatment approach means fewer side effects, making it safer for more patients, including those with weakened immune systems, such as cancer patients.
One of the most significant challenges in treating these viruses has been drug resistance. Over time, the viruses have adapted, making many current medications less effective. Existing treatments can also have severe side effects or provide only limited relief.
POM-L-BHDU stands out because it is much more potent against the varicella zoster and herpes simplex viruses, offering a new solution where other drugs are falling short.
Early tests of POM-L-BHDU have been encouraging. In studies on mouse models and human skin, the molecule demonstrated strong antiviral effects, particularly when used as a cream.
This success suggests that it could eventually be made available as an over-the-counter topical treatment, allowing people to manage outbreaks conveniently at home. Immediate application during the early stages of an outbreak could help reduce symptoms quickly and effectively.
The University of Georgia Research Foundation has partnered with Anterogen Co. to move this breakthrough toward clinical trials.
Phase 1 trials will be a critical step in determining whether POM-L-BHDU can safely and effectively help human patients. If successful, this new treatment could significantly improve the lives of people dealing with shingles and herpes.
This discovery is more than just a medical breakthrough—it represents a step forward in addressing long-standing challenges in treating viral infections.
By offering a safer, more effective, and versatile treatment option, POM-L-BHDU has the potential to improve the quality of life for millions of people worldwide.
Published in the Journal of Medicinal Chemistry, this study highlights the power of innovative research in tackling some of medicine’s most persistent problems.
