An estimated 25,000 Americans develop severe fungal infections霉菌感染,真菌感染 each year, leading to 10,000 deaths despite the use of anti-fungal drugs. The associated cost to the U.S. health care system has been estimated at $1 billion a year. Now two Syracuse University scientists have developed new brominated溴化的 furanones呋喃酮 that exhibit powerful anti-fungal properties.
The most virulent1剧毒的,恶性的 fungus2 is Candida albicans白色念珠菌, which is carried by about 75 percent of the public. Typically the fungus is harmless but, in individuals with HIV or otherwise compromised immune systems, it can cause candidiasis, which has a high mortality rate. The fungi3 can also form biofilms生物膜 that attach to surfaces and are up to 1,000 times more resistant4 to anti-fungals.
"These new furanones have the potential to control such infections and save lives," says assistant professor Dacheng Ren of the Department of Biomedical and Chemical Engineering in SU's L.C. Smith College of Engineering and Computer Science. "In our tests, they reduced fungal growth by more than 80 percent, and we hope to improve on that going forward."
Ren and his collaborator合作者, chemistry professor Yan-Yeung Luk of SU's College of Arts and Sciences, have filed a non-provisional patent application. They have also published related results in the Journal of Applied6 Microbiology and Biotechnology.
Over the past 20 years, pathogenic致病的,病原的 fungi have developed growing resistance to anti-fungal drugs. This stimulated7 a strong demand for more effective drugs and led to the successful research at Syracuse. The researchers' genomic study suggests that furanones have different genetic8 targets than current anti-fungal agents and thus may avoid drug resistance acquired in the past. The research team has also shown previously9 that these furanones inhibit10 bacterial11 biofilm formation; thus they may help control chronic12 infections where biofilms often appear, on surgical13, dental and other implants14.
Ongoing15 furanones research at Syracuse University will investigate a broad spectrum16 of other potential capabilities17, ranging from diverse medical uses, such as controlling bacterial and fungal biofilms, to anti-fungal wood preservatives18 for the building materials market.
