The Scully Ebola poster mentioned the compounds have "some toxicity associated with higher concentrations..." but this is pretty vague, and you can't really see any numbers on their graphs.
I'll answer this right now and come back to the earlier discussion tomorrow
The toxicity in higher concentrations were in cell culture studies. However, in the same paragraph Scully states that in th in vivo mouse studies the nanoviricide was well tolerated. Other studies indicated the nanoviricide was safe as high as 10 times the therapeutic level. Moreover, the later improved drug showed high efficacy at half or less the doses that were originally given. Keep in mind that 1) these are only observations from efficacy and proof of concept protocols and not toxicity protocols, and 2) even potable chlorinated drinking water shows in vitro toxicity in concentrations considered safe for consumption.
