Caftaric acid (trans-Caftaric acid) is a natural product with antioxidant and anti-inflammatory properties, antimutagenicity, and an inhibitor of protein-protein interactions mediated by Src family kinases.

L-Chicoric Acid (trans-Caffeoyltartaric acid) has been shown to inhibit hyaluronidase and HIV-1 integrase, and to possess phagoeytosis stimulatory activity in vitro and in vivo and antiviral acitivy. L-Chicoric acid may reduce acute alcohol-induced steatosis in mice through interfering with the induction of iNOS and iNOS-dependent signaling cascades in the liver. 3. L-Chicoric acid inhibited cell viability and induced apoptosis in 3T3-L1 preadipocytes which was characterized by chromatin condensation and poly ADP-ribose-polymerase (PARP) cleavage.

4-Ethylresorcinol has inhibitory activity against tyrosinase and acetylcholinesterase and can be used in biochemical experiments and drug synthesis.
