Santonin, a natural compound, is a sesquiterpene lactone. It is known as an anthelmintic drug which was used in the past (19th - early 20th centuries) mainly to treat different kinds of intestinal worms such as roundworm or ascaris lumbricoides except the tapeworm. It was also indicated for use in retention of urine and nocturnal enuresis from atony, urethral irritation with pain at uterine disorders, retention of urine in fevers, deficient spinal innervation, as evidenced by impaired respiration and tympanitis, vesical tenesmus and strangury, retention of urine from the use of opiates. Santonin was formerly listed in U.S. and British pharmacopoeia but due to the severe side effects and the development of many safer deworming drugsa it is no longer registered as a drug in most countries. Originally isolated from the poisons plant Artemisia maritima, santonin is itself a toxic compound. It is the anhydride of santonic acid, which is a derivative of dimethyl-naphtalene. It dissolves in alkalies with formation of salts of this acid. In acetic acid solution, when exposed to sunlight for about a month, santonin is converted into photosantonic acid. Santonin was found to have significant anti-inflammatory activity on acute inflammatory processes and as shown in vitro can activate pregnane X receptors and constitutive androstane receptors and subsequently increases the expression of drug-metabolizing enzymes.

Lead carbonate doesn’t have any biological or pharmacological application, but is known, that it can penetrate by inhalation or by ingestion. Lead carbonate may have effects on the blood, bone marrow, central nervous system, peripheral nervous system and kidneys, resulting in anemia, hemolysis, kidney impairment, and also it causes toxicity to human reproduction or development.

Gold trichloride is used as a catalyst in synthesis of new compounds. It was shown that gold trichloride was not the marker of contact allergy and could not be recommended in patch testing.

CALCIUM CHLORIDE HYDROXIDE HYPOCHLORITE, DIHYDRATE is an inert ingredient in pesticide products.

Stibophen (Fuadin), an organic trivalent antimony compound, has been used for many years in the treatment of schistosomiasis. Stibophen is used as treatment of schistosomiasis by intramuscular injection. Stibophen is known to act by selectively inhibiting worm PFK.

Phenyl salicylate belongs to the family of hydroxybenzoic acid derivatives. Phenyl salicylate is used as a food additive. Antimycobacterial activity of phenyl salicylates (salols) was studied in connection with antituberculotic activity of salicylic derivatives. Phenyl salicylates are esters. Phenyl salicylates (salols) represent a new group of antimycobacterial compounds. Phenyl salicylate is included in the number of medications, indicated for the treatment of symptoms of irritative voiding, used to relieve the discomfort, pain, frequent urge to urinate, and cramps/spasms of the urinary tract caused by an infection or a medical procedure. Phenyl salicylate works as a pain reliever in these combinations.

Picric acid is used as a high explosive, an oxidant in rocket fuels, in matches and leather processing, as a laboratory reagent for serum creatinine analysis in humans and experimental animals. There is not much information related to pharmacological and biological application of picric acid. But is known, that during the 1920s-30s, it was used either alone or in combination with butyl aminobenzoate as an antiseptic dressing for burn wounds. About 4% of patients treated with picric acid developed sensitization local dermatitis and at least one case of serious central nervous system dysfunction occurred following topical picric acid application. Picric acid does not sensitize directly, but only after conversion to a more reactive compound. Picric acid was positive in the Ames salmonella assay for mutagenicity when metabolic activation was present. It has also been reported to be non-mutagenic in the Ames test. Those contradictory results did not allow to draw a conclusion on picric acid mutagenicity. A review by a committee of the Health Council of the Netherlands in 2002, did not find published data on long-term toxicity, carcinogenicity, or reproductive toxicity.

Paraldehyde is the cyclic trimer of acetaldehyde molecules. It was introduced into clinical practice in the UK by the Italian physician Vincenzo Cervello in 1882. It is a central nervous system depressant and was soon found to be an effective anticonvulsant, hypnotic and sedative. It was included in some cough medicines as an expectorant (though there is no known mechanism for this function beyond the placebo effect). Paraldehyde also has been used in the treatment of alcoholism and in the treatment of nervous and mental conditions to calm or relax patients who are nervous or tense and to produce sleep. However, this medicine has generally been replaced by safer and more effective medicines for the treatment of alcoholism and in the treatment of nervous and mental conditions.

The most well known component of willow bark extract is salicin, it is a prodrug, which is gradually transported to the lower part of the intestine, hydrolyzed to saligenin by intestinal bacteria, and converted to salicylic acid after absorption. Salicin possesses an analgesic, anti-inflammatory, and antipyretic properties. Salicin suppressed the activation of MAPKs and NF-κB signaling pathways and thus maybe might be a potential therapeutic agent against inflammatory diseases.
