Abstract
The search for anti-inflammatory drugs is still challenging, even though recent advances in modern medicine have provided some relief. Coumarins, well known secondary metabolites widely distributed in plant kingdom, have successfully documented their candidature in the development of anti-inflammatory agents. Natural coumarins, including esculetin, umbelliferone, scopoletin and marmin showed potent anti-inflammatory activity through various targets, including COX-2, LOX, iNOS TNF-α, TXB2. Over the past decade, various synthetic modifications have been carried out on the scaffold of these natural products. The current review focuses on various synthetic and semi-synthetic modifications carried out on the coumarin nucleus with a primary focus on the evaluation of anti-inflammatory activity along with structureactivity relationship study.
