Angelicin is a furanocoumarin. Angelicin has anti-cancer, antiviral, and anti-inflammatory activities;it regulates LPS-induced inflammation via inhibiting MAPK/NF-κB pathways. Angelicin is a powerful inducer of erythroid differentiation and -globin mRNA accumulation of human leukemia K562 cells, it is a potential therapeutic approach in hematological disorders, including -beta-thalassemia and sickle cell anemia. ngelicin is a type of furan coumarin NF - κ B and MAPK signaling inhibitor with anti-inflammatory, antiviral, and anti-tumor activities. Angelicin can inhibit the lysis and replication of gamma herpesvirus (such as MHV-68), act in the early stages of viral infection, and may inhibit RTA gene expression (IC50=28.95 μ M). Angelicin also alleviates inflammatory responses by inhibiting NF - κ B phosphorylation and nuclear translocation, as well as inhibiting p38 and JNK phosphorylation. Angelicin downregulates anti apoptotic proteins (such as Bcl-2, Bcl xL, and Mcl-1) and activates caspase-9 and caspase-3 to induce apoptosis in neuroblastoma cells.

Vanillin is a single molecule extracted from vanilla beans and also a popular odor used widely in perfume, food and medicine.Vanillin can reversibly and non-competitively inhibit the cellulase activity at appropriate concentrations and the value of IC50 was estimated to be 30 g/L.Vanillin protects KSC from UVB irradiation and its effects may occur through the suppression of downstream step of MDM2 in UVB irradiation-induced p53 activation. Vanillin also inhibits yeast growth and fermentation. Vanillin is a member of the class of benzaldehydes carrying methoxy and hydroxy substituents at positions 3 and 4 respectively. It has a role as an antioxidant, a flavouring agent, an anticonvulsant, an anti-inflammatory agent and a plant metabolite. It is a member of benzaldehydes, a monomethoxybenzene and a member of phenols.
