isolated from the bacteria Streptomyces hawaiiensis in 1985 ... ADEP4 is one of those, and was reported in a paper published in 2005 ... [potential trials in coming years]

Gives an idea of the sort of development timescale we're talking about. It's almost 30 years from isolation to this point. Clinical trials would take another 10-15 years. So, if all goes well, that's 40 years from the initial discovery until a doctor starts making up prescriptions.
