Capobenic acid is an antiarrythmetic agent, vasodilator, antianginal used for the treatment of cardiac infarction.

Hopantenic acid (homopantothenic acid) is a central nervous system depressant. Formulated as the calcium salt, it is used as a pharmaceutical drug in the Russian Federation under the brand name Pantogam. In Russia it is widely used to treat a variety of neurological, psychological and psychiatric conditions. The drug has been on the pharmaceutical market since 1979 and has been proven to be safe even for children from 3 years old upwards. Hopantenic acid is a natural forming substance, has some of the lowest side effects and considered to be very safe. Use Pantogam to treat a wide variety of cognitive and nervous system disorders with combined sedative and mild stimulant effect. Hopantenic acid is not approved for use in Europe or the United States. GABA receptor agonist.

Iocarmic acid is a molecule used in seventies as a contrast media for myelography. Iocarmate meglumine (Dimer-X), a water-soluble salt of iocarmic acid was reported to be safe and best tolerated by central nervous system compared to metrizamide in a double-blind test in patients with symptoms of lumbar and sacral root involvement. In the experimental and clinical studies of Dimer-X used for ventriculography the apparent superiority of Dimer-X over Conray 60 and Angiografin as far as side effects were concerned was demonstrated, but there were no particular differences in the intensities of the ventriculograms obtained. Morphological studies of the ventricles and histological examinations of the ventricular walls 1 month after injections of Dimer-X into the ventricles of dogs showed no abnormalities. In the clinical studies, ventriculography Dimer-X, performed on patients with diseases of the central nervous system, produced ventriculograms of good diagnostic value with no side effects, such as convulsions, apart from mild headache or vomiting in 4 instances. Ventriculography with Dimer-X was carried in 15 infants with myelomeningocele and progressive hydrocephalus. However, as was shown in a number of studies iocarmate produced moderate to severe arachnoiditis from myelography in primates. Early meningitis side effects following lumbar radiculography with iocarmate meglumine were demonstrated.

Iophendylate (Pantopaque (in USA) or Myodil, formerly manufactures by Glaxo Laboratories (London,UK) was commonly used from the 1940s until the late 1980s for myelography, cisternography, and ventriculography; the use of oil-based contrast agents such as Myodil has been discontinued, and images of intradural oil-based contrast are rarely encountered at present. In 1942 Van Wagenen (a neurosurgical colleague of Warrens, at the University of Rochester) identified Iophendylate as causing chemical meningitis in 30 patients where "space-displacing masses within the spinal canal were suspected". Iophendylate has been shown to be both a radiographic and magnetic resonance (MR) contrast agent in patients with suspected cord abnormalities who underwent MR examination following myelography. The iophendylate appears as a linear band of high signal intensity along the dependent portion of the spinal canal on MR images obtained with a repetition time of 500 msec and an echo time of 30 msec. Recently was published report, where depicted a unique case of posteriorly located subdural trapped Myodil, about three decades after myelography. The clinical picture of that case highlighted that such a complication didn’t carry the risk of arachnoiditis and could remain silent for several decades. Although Iophendylate is not used for evaluation of spinal disease anymore in the modern diagnostic era, its former use and its intrathecal persistence makes its recognition in MR imaging important. That case emphasized the necessity of awareness about these rare features which continue to present even decades after abandonment of oil-based myelography.

Unithiol was developed in the Soviet Union in the late 1950s. It only became more widely used in America and Western Europe since the mid-1970s, and particularly since the late 1970s when the Heyl Company in Germany began production. It remained the mainstay of chelation treatment of arsenic and mercury intoxication for more than half a century. Unithiol has been used in the management of acute and chronic poisoning with a number of different metals and metalloids, and is particularly useful for arsenic, bismuth and mercury. Unithiol can be given parenterally or orally depending on the clinical situation and severity of poisoning. Its action mechanism is close that of complexones. Active sulfhydryl groups enter into reactions with thiol poisons present in blood and tissues, form not toxic complex with them eliminated with urine. The poisons fixation results in the body enzyme systems changed under the poisons effect functions restoration. It is efficient as an antidote in case of intoxications by arsenic and heavy metals salts.

Pangamic acid (6-O-(dimethylaminoacetyl)-D-gluconic acid) has been detected 1938 and described as a natural, universally occurring substance with multiple biological and medical functions. In this respect pangamic acid has been worldwide on the market since decades as a drug stimulating cellular respiration. In addition to the natural pangamic acid, diisopropylammonium dichloroacetate (DIPA), a synthetic product not found in biological material, is on the market requesting similar biological functions. Pangamic acid is the name given to a product originally claimed to contain D-gluconodimethyl aminoacetic acid, which was obtained from apricot kernels and later from rice bran. It is also referred to as vitamin B15, but pangamic acid is not generally recognized as a vitamin. Despite serious safety concerns, pangamic acid is used for improving exercise endurance; treating asthma and related diseases, skin conditions including eczema, lung problems, painful nerve and joint conditions, cancer, and arthritis; improving the oxygenation of the heart, brain, and other vital organs; and “detoxifying” the body. It is also used for treating alcoholism, hangovers, and fatigue; protecting against urban air pollutants; extending cell life; strengthening the immune system; lowering bloodcholesterol levels; and assisting in hormone regulation. Since there is no standard identity for the chemicals in pangamic acid, how it might work is unknown. Although pangamic acid is also called vitamin B15, there is no research that shows it is required by the body, as the term “vitamin” would suggest. The United States Food and Drug Administration has recommended seizing any chemicals advertised as pangamic acid and restraining the importation and interstate shipment of pangamic acid on the grounds that pangamic acid and pangamic acid products are unsafe for use and have no known nutritional properties

Sodium lactate is primarily indicated as a source of bicarbonate for prevention or control of mild to moderate metabolic acidosis in patients with restricted oral intake whose oxidative processes are not seriously impaired. Sodium Lactate is most commonly associated with an E number of “E325” Sodium Lactate blends are commonly used in meat and poultry products to extend shelf life and increase food safety. They have a broad antimicrobial action and are effective at inhibiting most spoilage and pathogenic bacteria. In addition sodium lactate is used in cosmetics as a humectant, providing moisture.

Menthyl lactate is derived from menthol, a compound that comes from peppermint oil, or is made synthetically. Menthol has a natural cooling effect, which makes it useful as a topical analgesic to treat skin irritation, pain, itching or sunburn. Despite its cooling benefits, menthol can be a skin irritant. Like menthol, menthyl lactate is cooling, but it causes less skin irritation than menthol. Menthyl lactate also has a refreshing, minty taste. For this reason, some manufacturers use it as a flavoring ingredient. The compound is recommended for use as a flavor in concentrations of 0.005% to 0.2% and in cosmetic and other external products in concentrations ranging from 0.2% to 2.0%. Menthyl lactate is a known compound available e.g. from Haarmann & Reimer GmbH (Germany) under the name FRESCOLAT, Type ML.
