Coumarin hybrids have shown potential in drug targeting due to their diverse biological activities, including antibacterial, anti-inflammatory, antiradical, oncolytic, and monoamine oxidase B inhibition effects. These compounds are used by researchers to develop new pharmaceuticals, some of which are hybrid chemicals with different pharmacological effects created through molecular hybridization. The combinations of these compounds exhibit multifunctional characteristics, making them promising for treating complex diseases such as cancer, Alzheimer's disease, dysmetabolic syndrome, AIDS, plasmodium infection, and cardiovascular disorders. This study summarizes findings on the development of various coumarin hybrids, groups them based on prospective therapeutic uses, and provides recommendations on possible structure–activity relationships. A total of 45 relevant papers published between 2004 and the beginning of 2024 were analyzed. The authors aimed to create and produce highly efficient, tailored coumarin hybrid molecules to help medicinal chemists cure a range of human ailments. Coumarins, which are naturally occurring chemicals, have remarkable medicinal potential and are secondary plant metabolites belonging to the flavonoid class. Plant-derived coumarin analogs such as scopoletin, esculetin, and cloricromen have antineoplastic, anti-inflammatory, and oxidative stress protection properties. Medicinal chemists are interested in creating novel, physiologically active compounds using the coumarin nucleus as a chemical framework. The main challenge in synthesizing appropriately functionalized synthetic coumarins is applying current knowledge to produce promising novel lead compounds. There are numerous types of coumarin derivatives, some of which occur naturally and others are synthesized.Coumarin hybrids have shown potential in drug targeting due to their diverse biological activities, including antibacterial, anti-inflammatory, antiradical, oncolytic, and monoamine oxidase B inhibition effects.
