University of Oklahoma Researchers Develop Novel Antibiotics with Light and Iron for Cancer Patients
A team of researchers at the University of Oklahoma (OU) has discovered a new method that could significantly improve treatments for antibiotic-resistant infections, cancer, and other diseases caused by gram-negative bacteria, without relying on costly and environmentally harmful precious metals.
Traditionally, the production of synthetic carbohydrates, key building blocks in many antibiotics, relies on expensive metals such as platinum and rhodium. These metals are not only costly but also require harsh conditions and pose environmental concerns during extraction. These carbohydrates are essential for helping antibiotics penetrate the outer membrane of gram-negative bacteria, such as Pseudomonas aeruginosa, a common and dangerous hospital-acquired infection affecting vulnerable patients.
The OU research team, led by Professor Indrajeet Sharma, developed a new technique that replaces precious metals with either iron or blue light. These alternatives are far more affordable, widely available, and less toxic. The method allows for more efficient and sustainable carbohydrate synthesis, offering a promising new route for antibiotic development.
This breakthrough opens new possibilities for modifying drugs in their later development stages, especially antibiotics based on synthetic carbohydrates. These carbohydrates not only improve how drugs enter bacteria but also enhance their water solubility, allowing for easier oral administration as pro-drugs. A pro-drug is a compound that becomes active only after being processed by the body, often helping the drug stay active longer and work more effectively.
