Researchers identify 53 existing drugs that may block Ebola virus from entering human cells

Researchers found 53 existing drugs that may keep the Ebola virus from entering human cells, a key step in the process of infection, according to a study led by researchers at the Icahn School of Medicine at Mount Sinai and the National Institutes of Health (NIH), and published today in the Nature Press journal Emerging Microbes and Infections.

Among the better known drug types shown to hinder infection by an Ebola virus model: several cancer drugs, antihistamines and antibiotics. Among the most effective at keeping the virus out of human cells were microtubule inhibitors used to treat cancer.

"In light of the historic and devastating outbreak of Ebola virus disease, there is an urgent need to rapidly develop useful treatments against Ebola infection, and our study results argue that repurposing existing drugs may be among the fastest ways to achieve this," said lead author Adolfo García-Sastre, PhD, Director of the Global Health and Emerging Pathogens Institute within the Icahn School of Medicine at Mount Sinai. "Many of the compounds identified in this study promise to become lead compounds in near-future drug development efforts studies targeting this virus," said Dr. García-Sastre, also the Fishberg Chair and Professor of Medicine (Infectious Diseases) within the School.

A few are listed below...
