Comprehensive Chemistry and Biology of Coumarins Scaffold covers detailed methods and protocols to synthetize Coumarin derivatives and different applications and future perspectives for these compounds. Coumarin-Based Scaffolds plays an important role in organic, bioorganic, and medicinal chemistry as they act as a bridge between chemistry, life sciences, and biochemical investigations. Coumarin is an important scaffold for designing, generating a wide variety of chemical libraries and drug-like candidates to obtain desired therapeutic and pharmacological properties. Specific functional groups are covered as well as the synthesis of bioactive compounds against specific pathological conditions. The discovery of new coumarin-based drug candidates during the last decades has been covered to assist the pharmaceutical, bioorganic and medicinal chemists for their further research on coumarin-based molecules.
