Title: Antiproliferative effect of a food coloring on colon cancer cell line
Author: M. Norizadeh Tazehkand

Abstract: 4-MEI (4-Methylimidazole) is used as a chemical intermediate, crude material or component in the manufacture of pharmaceuticals, photographic and photothermographic chemicals, dyes and pigments and agricultural chemicals. 4-MEI is unintentionally found in our food. Caramel colour (which is the most used beverage colouring and food), dark beers and common brands of cola drinks may comprise more than 100 μg of this compound per 12-ounce serving. 4-MEI is widely used by people and colon cancer is common in our countries. So, it was decided to do in vitro analysis of anti-cancer effect of 4-MEI by MTT test using htc-116 cell line.
In this study, mouse Htc-116 cell line was treated with 4-MEI concentrations of 300, 450, 600 and 750 µg/mL for 24 hours and 48 hours periods, after that antiproliferative effect of the 4-MEI was studied by MTT assay.
In this study 4-MEI at highest concentration of 24h and at all concentration for 48 h treatment time significantly inhibited cell proliferation when it was compared to control. Also, exposing to the 4-MEI for 48 hours led to a decrease in cells proliferation by concentration dependent manner. This result showed that 4-MEI had anticancer effect in htc-116 cells. However, it has to be evaluated with different new studies (Tab. 1, Fig. 4, Ref. 19).
