Implication

Narrative review demonstrates broad antimicrobial mechanisms of isatin-based scaffolds against drug-resistant pathogens, highlighting their therapeutic potential in combating multidrug resistance.

Key Points

Summarize the therapeutic potential, structure–activity relationships, and mechanistic targets of isatin and its synthetic derivatives in combating antimicrobial resistance.
Reviewed medicinal chemistry strategies modifying the 1H-indole-2,3-dione core into Schiff bases, Mannich bases, thiosemicarbazones, and heterocyclic hybrid conjugates.
Evaluated structure–activity relationships alongside biological data against bacterial, fungal, viral, and mycobacterial targets.
Isatin conjugates disrupt multiple biological pathways, including bacterial membrane integrity, cell-wall synthesis, biofilm formation, and essential enzymes such as FtsZ, CrtM, DNA gyrase, and topoisomerase IV.
Translational applicability of the isatin core is supported by regulatory approvals in oncology and clinical-stage anti-infective candidates like TD-1792 and Ro 23-9424.
