2,4-Dinitrobenzenesulfonic acid (DNBS; DNBSO) sodium salt (Sodium 2,4-dinitrobenzenesulfonate) is a classic colitis inducer that relies on activation of the NF-κB p65/COX-2/p38 pathway. As a hapten, 2,4-Dinitrobenzenesulfonic acid sodium salt stimulates the production of immune responses in colonic tissues, triggers oxidative stress and inflammatory reactions, and thereby leads to colonic injury. 2,4-Dinitrobenzenesulfonic acid sodium salt successfully induces models of colitis and ulcerative colitis in rats, causing pathological changes such as ulcers, edema, stenosis, shortening and organ adhesion in the distal colon, along with significant increases in the levels of inflammatory indicators and endoplasmic reticulum stress marker proteins. 2,4-Dinitrobenzenesulfonic acid sodium salt is widely used in studies on the mechanisms related to colitis and ulcerative colitis.

Benzanthrone is an immunotoxic, pro-inflammatory Photosensitizer. Benzanthrone upregulates iNOS, COX-2 and inflammatory cytokines; activates ERK1/2, p38, JNK, AP-1 and NF-κB; inhibits Nrf2; and induces oxidative stress and DNA damage. Upon radiation exposure, Benzanthrone generates singlet oxygen and superoxide anion radicals, induces photohemolysis and lipid peroxidation, and alters the levels of skin xenobiotic enzymes. Benzanthrone exhibits differential genotoxicity in different cell lines. Benzanthrone possesses skin tumor-initiating and promoting activities.
