Metabromsalan (or 3,5-dibromosalicylanilide) is a pesticide.

Cinoxate, a cinnamate, is a potent ultraviolet absorber at 289 nm. It is approved by FDA as the active ingredient in sunscreen compositions for over-the-counter (OTC) use at concentrations up to 3% and a minimum SPF value of not less than 2 in the finished product but is rarely used It can cause photoallergic contact dermatitis.

Pelargonic acid (also called as nonanoic acid), a naturally found in a variety of plants and food products is a cosmetic ingredient, that function as skin-conditioning agent. The Food and Drug Administration (FDA) has approved pelargonic acid as a food additive, and as an ingredient in solutions used commercially to peel fruits and vegetables. FDA considers it safe for humans to eat food containing small amounts of pelargonic acid.

Chloranil is an oxidant, practically useful for dehydrogenation to aromatic and alpha,beta-desaturated carbonyl compounds. Chloranil was found to inhibit human carboxylesterases: carboxylesterase 1 and 2, acetylcholinesterase and butyrylcholinesterase. In 1950s chloranil ointment was used for the treatment of psoriasis and onychomycosis.

Chlorindanol is an antiseptic agent which is rapidly leathal to vegetative bacteria (Trichophyton sp., C. albicans, E. histolytica cysts and trophozoites, T. vaginalis) and seprmatozoa in vitro. It is one of two active ingredients in a spermicidal contraceptive aerosol cream (Lanettes); with the other being laureth-9.

Mestranol is a biologically inactive prodrug of estrogen agonist ethinylestradiol. Enovid, a combination of mestranol and noretynodrel, was first oral contraceptive approved by FDA in 1960.

Diphenadione is a vitamin K antagonist that exhibits anticoagulant effects and is used as a rodenticide against rats, mice, voles, ground squirrels and others. When orally ingested it is toxic to mammals causing irregular heartbeat and major maladies associated with its impact on blood clotting. It is also used in South America to control vampire bat populations.

Reserpine is an alkaloid, isolated from the Rauwolfia serpentina plant and developed by Ciba pharma. Reserpine was approved by FDA for the treatment of hypertension and psychotic disorders. The drug exerts its effect by blocking two vesicular monoamine transporters, VMAT1 and VMAT2. The blockade results in vesicles that lose their ability to store neurotransmitter molecules. Neurotransmitters, thus retained in cytosol, are then neutralized by MAO.

The quinoline derivative diiodohydroxyquinoline (INN) or iodoquinol (USAN), one of the halogenated 8-quinolinols widely used as an intestinal antiseptic, especially as an antiamebic agent. Iodoquinol is also used topically in other infections and may cause CNS and eye damage. It was discovered by Adco Co. and introduced as diiodohydroxyquinoline. The mechanism of action is unknown. Iodoquinol acts against the trophozoites of Entamoeba histolytica. Iodoquinol produces its amebicidal effect at the site of infection, since it is poorly absorbed from the gastrointestinal tract and can reach high concentrations in the intestinal lumen.
