Trigonelline (N'-methylnicotinate)

Pyridinium, 3-carboxy-1-methyl-, hydroxide, inner salt

C7H7NO2 (137.0477)


Trigonelline, also known as caffearin or gynesine, belongs to the class of organic compounds known as alkaloids and derivatives. These are naturally occurring chemical compounds that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties. Also some synthetic compounds of similar structure are attributed to alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus. It is also found in coffee, where it may help to prevent dental caries by preventing the bacteria Streptococcus mutans from adhering to teeth. Trigonelline is an alkaloid with chemical formula C7H7NO2 and CAS number 535-83-1. Trigonelline is a product of the metabolism of niacin (vitamin B3) which is excreted in the urine. High amounts of trigonelline have been found in arabica coffee, fenugreeks, and common peas. Another foods such as yellow bell peppers, orange bellpeppers and muskmelons also contain trigonelline but in lower concentrations. Trigonelline has also been detected but not quantified in several different foods, such as rices, triticales, alfalfa, cereals and cereal products, and ryes. Trigonelline in the urine is a biomarker for the consumption of coffee, legumes and soy products. Alkaloid from fenugreek (Trigonella foenum-graecum) (Leguminosae), and very many other subspecies; also present in coffee beans and many animals.

2-Aminobenzoic acid

Anthranilic acid, calcium (2:1) salt

C7H7NO2 (137.0477)


2-Aminobenzoic acid, also known as anthranilic acid or O-aminobenzoate, belongs to the class of organic compounds known as aminobenzoic acids. These are benzoic acids containing an amine group attached to the benzene moiety. Within humans, 2-aminobenzoic acid participates in a number of enzymatic reactions. In particular, 2-aminobenzoic acid and formic acid can be biosynthesized from formylanthranilic acid through its interaction with the enzyme kynurenine formamidase. In addition, 2-aminobenzoic acid and L-alanine can be biosynthesized from L-kynurenine through its interaction with the enzyme kynureninase. It is a substrate of enzyme 2-Aminobenzoic acid hydroxylase in benzoate degradation via hydroxylation pathway (KEGG). In humans, 2-aminobenzoic acid is involved in tryptophan metabolism. Outside of the human body, 2-Aminobenzoic acid has been detected, but not quantified in several different foods, such as mamey sapotes, prairie turnips, rowals, natal plums, and hyacinth beans. This could make 2-aminobenzoic acid a potential biomarker for the consumption of these foods. 2-Aminobenzoic acid is a is a tryptophan-derived uremic toxin with multidirectional properties that can affect the hemostatic system. Uremic syndrome may affect any part of the body and can cause nausea, vomiting, loss of appetite, and weight loss. Chronic exposure of uremic toxins can lead to a number of conditions including renal damage, chronic kidney disease and cardiovascular disease. It can also cause changes in mental status, such as confusion, reduced awareness, agitation, psychosis, seizures, and coma. 2-Aminobenzoic acid is an organic compound. It is a substrate of enzyme anthranilate hydroxylase [EC 1.14.13.35] in benzoate degradation via hydroxylation pathway (KEGG). [HMDB].

4-Aminobenzoic acid

4-aminobenzoic acid

C7H7NO2 (137.0477)


p-Aminobenzoic acid, also known as 4-aminobenzoic acid or PABA, is an organic compound with molecular formula C7H7NO2. PABA is a white crystalline substance that is only slightly soluble in water. It consists of a benzene ring substituted with an amino group and a carboxylic acid. PABA is an essential nutrient for some bacteria and is sometimes called vitamin Bx. However, PABA is not essential for humans and it varies in its activity from other B vitamins. PABA is sometimes marketed as an essential nutrient under the premise that it can stimulate intestinal bacteria. Certain bacteria in the human intestinal tract such as E. coli generate PABA from chorismate. Humans lack the enzymes to convert PABA into folate, and therefore require folate from dietary sources such as green leafy vegetables. Although some intestinal bacteria can synthesize folate from PABA and some E. coli can synthesize folate this requires six enzymatic activities in folate synthesis which are not all done in the same bacteria. PABA used to be a common sunscreen agent until it was found to also be a sensitizer. The potassium salt of PABA is used therapeutically in fibrotic skin disorders. PABA can also be found in Acetobacter (DOI: 10.3181/00379727-52-14147).

4-Nitrotoluene, being a volatile organic compound, can potentially penetrate the skin epidermis under certain conditions. The skin is a complex barrier that can prevent many substances from entering the body, but it is not impervious to all chemicals, especially those that are small, lipophilic (fat-soluble), and volatile. The epidermis, the outermost layer of the skin, consists of several sub-layers, including the stratum corneum, which is the primary barrier to external agents. Substances can pass through the skin via two main routes: transcellular (through the cells) and intercellular (between the cells). The efficiency of this penetration depends on various factors, such as the concentration of the compound, the duration of exposure, the condition of the skin (e.g., damaged or intact), and the chemical's properties. In the case of 4-nitrotoluene, if there is direct contact with the skin, especially in liquid or high vapor concentration forms, it could potentially penetration through the skin layers. This is particularly a concern in occupational settings where workers might be exposed to this compound without adequate protection. To minimize the risk of skin absorption, it is crucial to use appropriate personal protective equipment, such as gloves and aprons, when handling 4-nitrotoluene or any other potentially hazardous chemicals. In case of skin contact, it is important to wash the affected area immediately with soap and water and seek medical attention if necessary.
