The hydroxylated benzene metabolite hydroquinone (HQ) is mainly generated from benzene, an important industrial chemical, and is also a common dietary component. Although numerous papers have addressed the potential role of HQ in tumorigenic responses, the immunosuppressive and anti-inflammatory effects

There are numerous common skin disorders involving hyperpigmentation, including solar lentigines, postinflammatory hyperpigmentation, melasma, freckles, and dyschromia from photoaging. While these conditions are of an aesthetic nature, there is great interest in newer, safer, and more effective treatment modalities. Topical

Tumor cells present a known metabolic reprogramming, which makes them more susceptible for a selective cellular death by modifying its mitochondrial bioenergetics. Anticancer action of the antioxidant 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one (HQ) on mouse mammary adenocarcinoma TA3, and its multiresistant variant TA3-MTXR, were
