Benzofurans have been found to be one of the major sources of drug development for a variety of diseases, and have received increasing attention in the field of synthetic medicinal chemistry. Dorsmerunin A, a natural cytotoxic product of 2-benzylbenzofurans, was isolated from the roots of Dorstenia kameruniana. In this work, Dorsmerunin A was firstly synthesized in 49% total yield from 4-methoxysalicylaldehyde and 2-bromo-4'-methoxyacetophenone through intramolecular condensation, reduction and deprotection. The in vitro anti-inflammatory activity of Dorsomerinein A was initially tested using the murine macrophage RAW264.7 model, and the results showed that it showed good inhibitory effect on NO production at a concentration of 25 μmol/L, as well as proinflammatory factors (IL-6, IL-1β and TNF-α).
