Butein, a chalconoid has anti-oxidant effect, which has various pharmacological effects.
Reactive oxygen species (ROS), produced intracellularly through multiple mechanisms and depending on the cell and tissue types, mainly ROS NADPH oxidase (NOX) complexes in cell membranes, mitochondria, peroxisomes, and endoplasmic reticulum, via dental adhesive bleaching agents and pulpal disease, can cause oxidative stress.  ROS are formed as a natural product of the normal metabolism of oxygen and have important roles in cell signaling and homeostasis. However, during times of environmental stress, ROS levels can increase dramatically. H2O2-induced cytotoxicity and production of ROS were blocked in the presence of butein, and these effects were dose dependent.Due to the dual role of ROS, both prooxidant and antioxidant-based anticancer agents have been developed.
Butein can induce the apoptosis in B16 melanoma cells and human promyelocytic leukemia cells, inhibit diabetes complications, and inhibit enzymes such as protein kinases and glutathione reductase. [3,4,5,6] Recently, Butein was isolated from R. verniciflua which suppress cellular damage from oxidation caused by H2O2 in HDP cells, through JNK–Nrf2/ARE-dependent HO-1 expression. In addition, Butein attenuated VEGF and MMP-9 activities via the suppression of NF-kB activity by flow cytometric analysis and RT-PCR in vitro. Furthermore, Butein repressed the expression of VEGF and MMP-9 induced by treatment with tumor necrosis factor-ɑ and phorbol-12-myristate-13-acetate mainly through Electrophoretic mobility shift assay (EMSA) and Enzyme-linked immunosorbent assay (ELISA), resulting in an inhibition of cell growth, invasion and angiogenesis of prostate cancer . Thus, Butein may be a promising therapeutic agent for the treatment of various dental diseases.
