Ray of Hope: Researchers Find 53 Drugs to Block Ebola

Researchers have found that 53 existing drugs may help keep the virus from entering human cells, a key step in the process of infection, paving the way of hope against the deadly virus.

In order to hinder infection by the ebola virus model, several cancer drugs, antihistamines and antibiotics are shown as the better known drug types. Whereas, the findings showed microtubule inhibitors that used to treat cancer as the most effective drug at keeping the virus out of human cells.

The team’s screen yielded 53 drugs that block Ebola virus-like particles from entering human cells. Whereas, other categories that blocked viral entry included estrogen receptor modulators used against cancer and serotonin reuptake inhibitors used to treat depression.

“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 from 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,” García-Sastre said.

There is no approved treatment for Ebola virus infection, and the estimated mortality rate of the current Ebola outbreak is nearly 70 percent in many areas. Antibody-based therapy (e.g. ZMapp) has proven effective in animal studies, and has been used for the treatment of a few patients, but has not been confirmed in clinical trials.

Meanwhile, it is also expensive to make and in short supply. Ebola vaccine trials are getting underway as well, but vaccines will not be available for some time.

For the study, the researchers screened through sample libraries of 2,816 compounds already approved by the US Food and Drug Administration for other uses.

The test was designed to identify compounds that blocked the ability of the Ebola virus to enter and infect human cells by at least 50 percent.

The study appeared in the journal Emerging Microbes and Infections. (IANS)
