Gentisic acid is an active metabolite of salicylic acid degradation, which possesses a broad spectrum of biological activity, such as anti-inflammatory, antirheumatic and antioxidant properties. The antioxidant activity and radioprotective properties of gentisic acid are exerted by its phenoxyl group. It is also used in cosmetics as a skin-whitening agent for the treatment of skin pigmentary disorders by influencing the synthesis of melanin through inhibition of melanosomal tyrosinase activity Gentisic acid is also a biomarker of Renal Cell Carcinoma.

Doconexent (Docosahexaenoic acid, DHA) is an omega-3 fatty acid that is a primary structural component of the human brain, cerebral cortex, skin, and retina. DHA is widely used as a food supplement, and is beleived to support healthy brain development in young childred, prevent cardiovascular disease and cognitive decline during Alzheimer's disease. Most of these claims, however, were not supported by clinical trials. DHA spray is used as a tanner.

Erythorbic acid, an epimer of L-ascorbic acid, is used in the United States as a food additive. It was studied, that erythorbic acid enhanced of iron absorption and could play a major role in enhancing iron bioavailability from mixed diets that include foods preserved with erythorbic acid. In addition, was investigated if the erythorbic acid could influence on the metabolism of vitamin C in young women, and obtained results showed, that prolonged ingestion of erythorbic acid had no effect on vitamin C uptake or clearance from the body.

2-Methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid (AMPS) is an fda approved for use in polymer components of food-contact paper and board adhesive. Poly(2-acrylamido-2-methyl-1-propanesulfonic acid)(PAMPS)] has been found to inhibit the cytopathicity of HIV-1 and HIV-2 in MT-4 cells at concentrations that are not toxic to the host cells. It also inhibited syncytium formation in co-cultures of MOLT-4 cells with HIV-1- or HIV-2-infected HUT-78 cells. It inhibited binding of anti-gp120 mAb to HIV-1 gp120 and blocked adsorption of HIV-1 virions to MT-4 cells.
