"Researchers have developed", yeah. When I read such things, I always recall https://en.wikipedia.org/wiki/Epimerox - this thing promised wonders - very broad spectrum, very low toxicity - and, most importantly, it was targeting a conservative essential protein - so nearly zero resistance. And there were no updates for more than a decade.
Something developed in a lab is something we, most likely, will never see - and will never know why the thing didn't reach the 2nd stage (or the 1st).
