Neohesperidin Dihydrochalcone (Neohesperidin DC) is an artificial sweetener derived from citrus.

Administration of neohesperidin dihydrochalcone significantly reduces the activities of AST and ALT, both key markers of liver damage. It also inhibits the expression of NF-κB, IL-6, IL-1β, and TNF-α proteins, which are elevated in the liver of PQ-treated mice, indicating its potential protective effects on liver inflammation and damage[3]. Furthermore, studies on Wistar Crl:(WI)WU BR rats to assess the embryotoxicity and teratogenicity of neohesperidin dihydrochalcone reveal no adverse effects at dietary levels up to 5%, the highest dose investigated. At this level, rats consumed approximately 3.3 g/kg body weight/day[4], demonstrating the compound's safety at significant dosage levels.

WST-8 dye is used in the cell viability assay. HIT-T15 and HUVEC cells are grown and maintained in Dulbecco's modified Eagle's medium, supplemented with 10% fetal bovine calf serum. 1000 cells in each well are incubated with various concentrations of neohesperidin dihydrochalcone (50, 100, 500 μM, 1 mM) and other compounds. After treating HIT-T15 and HUVEC cells with 500 μM HOCl, WST-8 dye is added to each well, and the absorbance is detected at 420 nm with microplate reader[1].
