Description and Uses

1,4-Dimethylnaphthalene is a polycyclic aromatic hydrocarbon (PAH) that has been found in dust particulate matter and is associated with activation of aryl hydrocarbon receptor as a major toxic mode of action in WB-F344 cell line. 1,4-Dimethylnaphthalene has been found to retard the development of epidermoid carcinomas in hamster buccal pouch. 1,4-Dimethylnaphthalene alters the genes associated with the maintenance of a G1/S phase block possibly through the induction of the cell cycle inhibitors KRP1 and KRP2 in potatoes.
