I want to know the answer to the following question:
Besides semisytetic modifications, what advances in medicinal chemistry regarding antibacterials?
All the background I'm provided with is that "Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterials—for example, the sulfonamides, the quinolones, and the oxazolidinones—are produced solely by chemical synthesis.". Is that enough to answer the question?
Answer: no
