hus, antibacterial activity can presumably be enhanced by introducing appropriate hydrophobic chains and extending the distance between the urea bond and the aryl group
The study shows that introducing urea linkages and modifying the distance between the urea group and the aromatic ring improves antibacterial activity, but it does not fully explain the underlying chemical reason. How does increasing the linker length or flexibility influence the binding interactions between the drug and the bacterial ribosome at a molecular level? Would further increasing chain length continue to improve activity, or is there an optimal balance between flexibility and binding specificity?
