While existing work focuses on modifying known antibiotic scaffolds (β-lactams, fluoroquinolones, imidazoles), there is no systematic approach to discovering entirely novel chemical structures from natural products with antibiotic properties. Prior work emphasizes that most recently developed antibacterials belong to existing structural classes, yet natural product isolation and structure elucidation efforts remain disconnected from bioactivity evaluation and molecular target identification.

Structure–activity relationship (SAR) data for novel natural product-derived scaffolds against multidrug-resistant pathogens are lacking. While SAR analyses exist for synthetic modifications of known classes, there is no systematic SAR framework for natural products with novel chemical structures, particularly regarding which structural features in natural scaffolds confer resistance to common bacterial resistance mechanisms.

Natural product-derived antibiotic candidates lack comprehensive ADMET (absorption, distribution, metabolism, excretion, toxicity) profiling before synthesis and biological evaluation. Existing synthetic antibiotic development includes ADMET prediction to guide compound design, but natural product discovery programs do not systematically apply these pharmacokinetic criteria to prioritize which novel structures warrant further development.
