Ebola virus can cause severe hemorrhagic disease with high fatality rates. Currently, no specific therapeutic agent or vaccine has been approved for treatment and prevention of Ebola virus infection of humans. Although the number of Ebola cases has fallen in the last few weeks, multiple outbreaks of Ebola virus infection and the likelihood of future exposure highlight the need for development and rapid evaluation of pre- and postexposure treatments. Here, we briefly review the existing and future options for anti-Ebola therapy, based on the data coming from rare clinical reports, studies on animals, and results from in vitro models. We also project the mechanistic hypotheses of several potential drugs against Ebola virus, including small-molecule-based drugs, which are under development and being tested in animal models or in vitro using various cell types. Our paper discusses strategies toward identifying and testing anti-Ebola virus properties of known and medically approved drugs, especially those that can limit the pathological inflammatory response in Ebola patients and thereby provide protection from mortality. We underline the importance of developing combinational therapy for better treatment outcomes for Ebola patients.

The current Ebola virus outbreak is unprecedented in its scope and international impact. Given that there are currently no approved antivirals to treat Ebola virus, there is urgency to conduct more rapid development and evaluation of Ebola antivirals. Recently, the World Health Organization identified a number of antivirals as high priority to include AVI-6002 (AVI-7537 and AVI-7539), BCX4430, brincidofovir, favipiravir, and TKM-100802. This review describes these chemically synthesized inhibitors of Ebola virus, relevant patent development and gives an update on their current status.
