Glycerin (glycerol) is 3-carbon alcohol naturally occurring in the human body. It is the structural backbone triacylglycerol molecules, and can also be converted to a glycolytic substrate for subsequent metabolism. Glycerin is a colorless, odorless, viscous, sweet-tasting liquid. The FDA classifies glycerol as "generally recognized as safe". Glycerin is used in the pharmaceutical industry as a sweetener in syrups, lozenges, and as an excipient in eyewash solutions. As an individual prescription product, glycerin has uses as a hyperosmotic, osmotic diuretic, and ophthalmic agent. It may be used as an eye drop in the treatment of glaucoma to reduce intraocular pressure, as a solution or suppository for short-term treatment of constipation, to evacuate the bowel prior to a colonoscopy, and in some ocular surgeries. It may be given intravenously to reduce pressure inside the brain and used externally on the skin as a moisturizer. Glycerin has many other uses in the agricultural, food and pharmaceutical industry.

Aspirin is a nonsteroidal anti-inflammatory drug. Aspirin is unique in this class of drugs because it irreversibly inhibits both COX-1 and COX-2 activity by acetylating a serine residue (Ser529 and Ser516, respectively) positioned in the arachidonic acid-binding channel, thus inhibiting the synthesis of prostaglandins and reducing the inflammatory response. The drug is used either alone or in combination with other compounds for the treatment of pain, headache, as well as for reducing the risk of stroke and heart attacks in patients with brain ischemia and cardiovascular diseases.

Methyl salicylate (or methyl 2-hydroxybenzoate), also known as wintergreen oil, is a natural product and is present in white wine, tea, porcini mushroom Boletus edulis, Bourbon vanilla, clary sage, red sage and fruits including cherry, apple, raspberry, papaya and plum. Methyl salicylate is topically used in combination with methanol and under brand name SALONPAS to temporarily relieves mild to moderate aches and pains of muscles and joints associated with: strains, sprains, simple backache, arthritis, bruises. The precise mechanism of action of methyl salicylate is not known, but there is suggested, that it cause dilation of the capillaries thereby increasing blood flow to the area.

Trimethylcolchicinic acid (also known as deacetyl colchicine) was used for patients with advanced malignancies. However, these studies were discontinued. Expeiments on rat were shown, that trimethylcolchicinic acid was able to improve normal liver histology, ultrastructure, collagen content and biochemical markers of liver damage in spite of that trimethylcolchicinic acid, didn't bind tubulin.

Enoxacin is an oral broad-spectrum fluoroquinolone antibacterial agent used in the treatment of urinary tract infections and gonorrhea. Enoxacin is bactericidal drugs, eradicating bacteria by interfering with DNA replication. Like other fluoroquinolones, enoxacin functions by inhibiting bacterial DNA gyrase and topoisomerase IV. The inhibition of these enzymes prevents bacterial DNA replication, transcription, repair and recombination. Enoxacin is active against many Gram-positive bacteria. After oral administration enoxacin is rapidly and well absorbed from the gastrointestinal tract. The antibiotic is widely distributed throughout the body and in the different biological tissues. Tissue concentrations often exceed serum concentrations. The binding of enoxacin to serum proteins is 35 to 40%. The serum elimination half-life, in subjects with normal renal function, is approximately 6 hours. Approximately 60% of an orally administered dose is excreted in the urine as unchanged drug within 24 hours. Enoxacin, like other fluoroquinolones, is known to trigger seizures or lower the seizure threshold. The compound should not be administered to patients with epilepsy or a personal history of previous convulsive attacks as may promote the onset of these disorders.

Dihydro-alpha-ergocryptine is an ergot alkaloid that has an agonist activity on D2 dopaminergic receptors and a partial agonist activity on D1 receptors. It also demonstrated antagonistic activity towards alpha-adrenergic receptors. The drug was approved by FDA in combination with other alkaloids (dihydroergocornine, dihydroergocristine and dihydro-beta-ergocryptine mesylate salts) under the name Hydergine for the treatment of dimentia and cerebrovascular insufficiency.

Urethane (Ethyl carbamate) is is an ethyl ester of carbamic acid, that has been found in many fermented food products and alcoholic beverages such as cheese, bread, yogurt, wine, whiskey, soya sauce etc. An in vitro study indicated that Urethane has a potential to inhibit the growth of bacteria, plant tissue, and rat carcinoma. Urethane has been used for many years as an antineoplastic agent for medical purposes but this application ended after it was discovered to be carcinogenic in 1943. Urethane can produce long-lasting anesthesia without affecting blood gases or blood pressure, it has been used in acute studies. In earlier studies, Urethane was also used as a co-solvent for water-insoluble analgesic and sedative drugs in Japan. By US FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use. However, small quantities of ethyl carbamate are also used in laboratories as an anesthetic for animals.

Acetone (or propanone) is the smallest and simplest ketone, which is used in cosmetic as a nail polish remover. Acetone is produced within the body because of the breakdown of stored fats and lipids as a source of energy. Such conditions as physical exercise and prolonged dieting, which lead to cleavage of fat within the body, may result in higher than average amounts of acetone in the bloodstream. The concentration of acetone in the environment doesn’t cause a neurotoxic, carcinogenic, or reproductive health hazard effect. In addition, experiments on rodents have shown that acetone possesses anticonvulsant properties.

Diethyl ether (ether) had been widely used for anesthesia until the 1960s despite its explosive properties and toxicity to both humans and animals. Diethyl ether still serves a role today as an effective inhalation agent. Newer inhalation agents have replaced ether completely and open drop delivery systems have been exchanged for complicated vaporizers and monitoring systems. Anesthesia in the developing world, however, still closely resembles primitive anesthetics.

Cyproterone acetate is a steroid drug which was developed by Schering A.G (now Bayer). Cyproterone acetate was approved in Canada, Asia, Latin America and Europe for the treatment of sever acne under the name Diane-35 (ethinyl estradiol) and its mechanism of action in this condition is explained by competitive inhibition of androgen receptor AR. In Canada cyproterone acetate is widely used as a contraceptive, however its usage is associated with liver toxicity and clots formation. In the UK the drug is marketed for the treatment of prostate cancer (Cyproterone acetate brand name).
