Biochem/physiol Actions

7,8-Dihydroxycoumarinan is an inhibitor of protein kinases. It is an active lactone present in plants such as Daphne Korean Nakai,[1] and Thymelaeaceae Daphne.[2] It serves as as analgesic, antiviral and antibacterial agent. 7,8-Dihydroxycoumarinan is found to induce tumor apoptosis via a number of signalling pathways. Thus, it is believed to exhibit antitumor effects. 7,8-Dihydroxycoumarinan might also be useful in treating lung carcinoma.[1] It is also known to be used in treating coagulation disorders and rheumatoid arthritis. 7,8-Dihydroxycoumarinan is known to induce neurite growth and lengthen neuronal survival.[3] It helps in clearing substances inducing necrosis, maintains water-electrolytes balance and energy metabolism. 7,8-Dihydroxycoumarinan is involved in the generation of neurotrophic factor and helps in restoring neuron function.[2]
