A new drug is developed that targets and binds to the lipid A portion of LPS from Gram-negative bacterial cells. This drug shows a high degree of activity and binding in a test tube setting against purified lipid A. Based on this information,
A. we should fast track this drug and get it out to physicians immediately to help prevent toxic/septic shock in humans. B. we should do some animal testing with whole Gram-negative cells and the drug before we jump to any conclusions. C. we should next proceed by moving to testing in a test tube using whole Gram-negative cells to see if it binds with the same strength. D. we should abandon the drug entirely. Binding to lipid A won't kill the bacteria, so the drug is useless to develop further. It wouldn't help humans who have septic shock at all.
