Washington: Closantel, an old drug used to treat sheep and cattle infected with liver fluke, may prove effective in fighting river blindness in humans, a major cause of infection-related blindness, according to a new study.River blindness is caused by thread-like filarial nematode worms, Onchocerca volvulus, which are transmitted among humans through the bite of a black fly.
This creates a critical need to identify new drug targets and agents that can effectively treat the disease.The new research by scientists at The Scripps Research Institute has shown that clostanel has the potential to inhibit the molting process of the parasite that causes the disease."We think this finding holds terrific potential for the treatment of river blindness, one of 13 recognized neglected tropical diseases," said Scripps Research postdoctoral fellow Christian Gloeckner, the first author of the study.The study is scheduled for publication in an advance, online Early Edition of the journal Proceedings of the National Academy of Sciences (PNAS) during the week of February 8, 2010.
