A new antifungal molecule, devised by tweaking the structure of prominent antifungal drug Amphotericin B, has the potential to harness the drug’s power against fungal infections while doing away with its toxicity, report researchers at the University of Illinois Urbana-Champaign and collaborators at the University of Wisconsin-Madison. They reported their findings in the journal Nature.

Advanced molecular imaging technology has now mapped the structure of a drug widely used to treat fungal infections but whose workings have mystified researchers and physicians for nearly 70 years.

In a new study, researchers at the University of Illinois Urbana-Champaign, the University of Wisconsin, Madison and the National Institutes of Health described in atomistic detail the structure of the drug amphotericin B, a powerful but toxic antifungal agent.

A drug widely used to treat fungal infections improved key biomarkers in lung tissue cultures as well as in the noses of patients with cystic fibrosis, a clinical study by researchers at the University of Illinois Urbana-Champaign and the University of Iowa found.

Cystic fibrosis is caused by a missing or defective ion channel in the lining of the lungs, called CFTR. This leaves patients vulnerable to lung infections. Treatments called modulators can help some but not all patients, based on which type of genetic mutation causes the symptoms.
