AMINOBENZOATE SODIUM is a salt of Aminobenzoic acid. Aminobenzoic acid is an intermediate in the synthesis of folate by bacteria, plants, and fungi. Many bacteria, including those found in the human intestinal tract such as E. coli, generate Aminobenzoic acid from chorismate by the combined action of the enzymes 4-amino-4-deoxychorismate synthase and 4-amino-4-deoxychorismate lyase. Plants produce Aminobenzoic acid in their chloroplasts, and store it as a glucose ester (pABA-Glc) in their tissues. Humans lack the enzymes to convert Aminobenzoic acid to folate, so require folate from dietary sources such as green leafy vegetables. In humans, Aminobenzoic acid is considered nonessential and, although it has been referred to historically as "vitamin Bx", is no longer recognized as a vitamin, because most people have colon bacteria that generate Aminobenzoic acid. The potassium salt is used as a drug against fibrotic skin disorders, such as Peyronie's disease, under the trade name Potaba.

OCTANOIC ACID (Caprylic acid) eight-carbon saturated fatty acid belongs to the class of mediumchain saturated fatty acids. OCTANOIC ACID found naturally in the milk of various mammals, and as a minor constituent of coconut oil and palm kernel oil. Caprylic acid is used commercially in the production of esters used in perfumery and also in the manufacture of dyes. Caprylic acid is an antimicrobial pesticide used as a food contact surface sanitizer in commercial food handling establishments on dairy equipment, food processing equipment, breweries, wineries, and beverage processing plants. It is also used as disinfectant in health care facilities, schools/colleges, animal care/veterinary facilities, industrial facilities, office buildings, recreational facilities, retail and wholesale establishments, livestock premises, restaurants, and hotels/motels. In addition, caprylic acid is used as an algaecide, bactericide, and fungicide in nurseries, greenhouses, garden centers, and interiorscapes on ornamentals. Products containing caprylic acid are formulated as soluble concentrate/liquids and ready-to-use liquids.
Glutamic acid is a non-essential aminoacid used in biosynthesis of proteins. Besides being a building block of proteins, glutamic acid plays a principal role in neural activation. Glutamate is also responsible for the umami (savory) flavor of certain foods. In medicine, glutamate is used as a metabolic supplemnet in patients undergoing coronary surgery.
Pantothenic acid (known as Vitamin B5) is a water-soluble member of the B-vitamin family that is converted into 4’-phosphopantetheine, which is then converted to co-enzyme A (CoA) via adenosine triphosphate. Pantothenic acid regulates epidermal barrier function and keratinocytes differentiation via CoA metabolism. Pantothenic acid is incorporated into co-enzyme A and protects cells against peroxidative damage by increasing the level of glutathione. A recent feasibility study has also shown that daily oral supplementation of a nutritional agent containing pantothenic acid for 8 weeks was feasible and safe. It was discovered the different pharmacological implementation of pantothenic acid, such as treatment of acne, obesity. Existed some reports, mentioned efficacy using pantothenic acid in systemic lupus erythematosus. Significant reduction in morning stiffness, degree of disability, and severity of pain was reported for persons taking pantothenic acid in case of osteoarthritis and rheumatoid arthritis. Vitamin B5 may increase the effects of a group of drugs called cholinesterase inhibitors, which are used to treat Alzheimer's disease. That might lead to severe side effects.

MERSALYL (Mersal) is an organomercury compound, mercurial diuretics that superseded by safer diuretics such as thiazides, and is hardly used anymore. Due to the idiosyncratic nature of mercury toxicity, the risk of severe disease and sudden death are unpredictable and frequently show no warning signs. Mercurial diuretics cause diuresis by reducing the reabsorption sodium in the ascending loop of Henle, thus causing more water being delivered to the distal convoluted tubule. Unfortunately, earlier physicians misconstrued hallmark symptoms of mercury poisoning such as excessive salivation as signs of mercury's efficacy, including up until the early 1960s when the use of mercurial diuretics was halted in medicine.

Succinic acid is a dicarboxylic acid, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ATP, and as a signaling molecule reflecting the cellular metabolic state. Succinate is generated in mitochondria via the tricarboxylic acid cycle (TCA), an energy-yielding process shared by all organisms. Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space, changing gene expression patterns, modulating epigenetic landscape or demonstrating hormone-like signaling. Dysregulation of succinate synthesis, and therefore ATP synthesis, happens in some genetic mitochondrial diseases, such as Leigh's disease, and Mela's disease and degradation can lead to pathological conditions, such as malignant transformation, inflammation and tissue injury. Succinic acid is a precursor to some polyesters and a component of some alkyd resins. Succinic acid also serves as the bases of certain biodegradable polymers, which are of interest in tissue engineering applications. As a food additive and dietary supplement, succinic acid is generally recognized as safe by the U.S. Food and Drug Administration. Succinic acid is used primarily as an acidity regulator in the food and beverage industry. It is also available as a flavoring agent, contributing a somewhat sour and astringent component to umami taste.[11] As an excipient in pharmaceutical products, it is also used to control acidity or as a counter ion. Drugs involving succinate include metoprolol succinate, sumatriptan succinate, Doxylamine succinate or solifenacin succinate.

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.
