To be sure nothing is missed, the Army lab will eventually try every category of medicine sold around the world, no matter what it is intended for. It will screen all 880 drugs in a collection of chemically unique medicines maintained by Prestwick Chemical Inc.
Much of the testing, though, will not involve the exhaustive screening given to the top prospects. Instead, the labs will load five drugs into each of the compartments on its trays, then go back and figure out which one was responsible if they get a hit.
Already, the labs have screened 3,000 compounds with this quick run-through. And one of them, submitted by a small pharmaceutical company, stopped the virus. The next step will be to test the five separately to see which one did it.
