Phenol sulfate
Phenol sulphate, also known as phenylsulfate or aryl sulphate, belongs to the class of organic compounds known as phenylsulfates. Phenylsulfates are compounds containing a sulfate group conjugated to a phenyl group. In normal humans, phenol sulphate is primarily a gut-derived metabolite that arises from the activity of the bacterial enzyme tyrosine phenol-lyase, which is responsible for the synthesis of phenol from dietary tyrosine (PMID: 31015435). Phenol sulphate can also arise from the consumption of phenol or from phenol poisoning (PMID: 473790). Phenol sulphate is produced from the conjugation of phenol with sulphate in the liver. In particular, phenol sulphate can be biosynthesized from phenol and phosphoadenosine phosphosulfate through the action of the enzyme sulfotransferase 1A1 in the liver. Phenol sulphate can be found in most mammals (mice, rats, sheep, dogs, humans) and likely most animals. Phenol sulphate is a uremic toxin (PMID: 30068866). It is a protein-bound uremic solute that induces reactive oxygen species (ROS) production and decreases glutathione levels, rendering cells vulnerable to oxidative stress (PMID: 29474405). In experimental models of diabetes, phenol sulphate administration has been shown to induce albuminuria and podocyte damage. In a diabetic patient cohort, phenol sulphate levels were found to significantly correlate with basal and predicted 2-year progression of albuminuria in patients with microalbuminuria (PMID: 31015435).
Dopamine 3-O-sulfate
Dopamine 3-O-sulfate is a sulfonated form of dopamine. In human blood circulation endogenous dopamine exists predominantly in the sulfated form and dopamine sulfate accounts for more than 90\\% of all dopamine. Dopamine-3-O-sulfate predominates in human plasma, with concentrations about 10-fold higher than those of the regioisomer dopamine-4-O-sulfate. Sulfonation is the most important metabolic pathway that interferes with the binding of dopamine to its receptors. The origins of this preponderance for Dopamine-3-O-sulfate have not been determined, although there has been speculation about the contribution of the specificity of transport proteins and/or arylsulfatases. It has also been proposed to depend on the regiospecificity of the metabolizing enzyme(s) for the 3-hydroxy group of dopamine. It is believed that the vast majority of circulating dopamine sulfate originates in the upper gastrointestinal tract, and indeed that is the main site of expression of the enzyme responsible for its formation. Aryl sulfotransferase (SULT1A3, EC 2.8.2.1) is an enzyme that catalyzes the sulfonation of many endogenous and exogenous phenols and catechols; the most important endogenous substrate is dopamine. SULT1A3 strongly favors the 3-hydroxy group of dopamine over the 4-hydroxy group and may indeed be primarily responsible for the difference between the circulating levels of dopamine sulfates in human blood.

Thymol Sulfate is also known as Thymol sulfuric acid. Thymol Sulfate is considered to be practically insoluble (in water) and acidic.

Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from T. vulgaris. Thymol is only slightly soluble in water at neutral pH, but it is extremely soluble in alcohols and other organic solvents. It is also soluble in strongly alkaline aqueous solutions due to deprotonation of the phenol. Its dissociation constant (pKa) is 10.59±0.10.[5] Thymol absorbs maximum UV radiation at 274 nm.[6] Ancient Egyptians used thyme for embalming.[9] The ancient Greeks used it in their baths and burned it as incense in their temples, believing it was a source of courage. The spread of thyme throughout Europe was thought to be due to the Romans, as they used it to purify their rooms and to "give an aromatic flavour to cheese and liqueurs".[10] In the European Middle Ages, the herb was placed beneath pillows to aid sleep and ward off nightmares.[11] In this period, women also often gave knights and warriors gifts that included thyme leaves, because it was believed to bring courage to the bearer. Thyme was also used as incense and placed on coffins during funerals, because it was supposed to ensure passage into the next life.[12] The bee balms Monarda fistulosa and Monarda didyma, North American wildflowers, are natural sources of thymol. The Blackfoot Native Americans recognized these plants' strong antiseptic action and used poultices of the plants for skin infections and minor wounds. A tisane made from them was also used to treat mouth and throat infections caused by dental caries and gingivitis.[13] Thymol was first isolated by German chemist Caspar Neumann in 1719.[14] In 1853, French chemist Alexandre Lallemand[15] (1816-1886) named thymol and determined its empirical formula.[16] Thymol was first synthesized by Swedish chemist Oskar Widman[17] (1852-1930) in 1882.[18]

N-Palmitoyl Asparagine
N-palmitoyl asparagine, also known as propyl paraben sulfate or propyl 4-sulfooxybenzoate belongs to the class of compounds known as N-acylamides. These are molecules characterized by a fatty acyl group linked to a primary amine by an amide bond. More specifically, it is a Palmitic acid amide of Asparagine. It is believed that there are more than 800 types of N-acylamides in the human body. N-acylamides fall into several categories: amino acid conjugates (e.g., those acyl amides conjugated with amino acids), neurotransmitter conjugates (e.g., those acylamides conjugated with neurotransmitters), ethanolamine conjugates (e.g., those acylamides conjugated to ethanolamine), and taurine conjugates (e.g., those acyamides conjugated to taurine). N-Palmitoyl Asparagine is an amino acid conjugate. N-acylamides can be classified into 9 different categories depending on the size of their acyl-group: 1) short-chain N-acylamides; 2) medium-chain N-acylamides; 3) long-chain N-acylamides; and 4) very long-chain N-acylamides; 5) hydroxy N-acylamides; 6) branched chain N-acylamides; 7) unsaturated N-acylamides; 8) dicarboxylic N-acylamides and 9) miscellaneous N-acylamides. N-Palmitoyl Asparagine is therefore classified as a long chain N-acylamide. N-acyl amides have a variety of signaling functions in physiology, including in cardiovascular activity, metabolic homeostasis, memory, cognition, pain, motor control and others (PMID: 15655504). N-acyl amides have also been shown to play a role in cell migration, inflammation and certain pathological conditions such as diabetes, cancer, neurodegenerative disease, and obesity (PMID: 23144998; PMID: 25136293; PMID: 28854168).N-acyl amides can be synthesized both endogenously and by gut microbiota (PMID: 28854168). N-acylamides can be biosynthesized via different routes, depending on the parent amine group. N-acyl ethanolamines (NAEs) are formed via the hydrolysis of an unusual phospholipid precursor, N-acyl-phosphatidylethanolamine (NAPE), by a specific phospholipase D. N-acyl amino acids are synthesized via a circulating peptidase M20 domain containing 1 (PM20D1), which can catalyze the bidirectional the condensation and hydrolysis of a variety of N-acyl amino acids. The degradation of N-acylamides is largely mediated by an enzyme called fatty acid amide hydrolase (FAAH), which catalyzes the hydrolysis of N-acylamides into fatty acids and the biogenic amines. Many N-acylamides are involved in lipid signaling system through interactions with transient receptor potential channels (TRP). TRP channel proteins interact with N-acyl amides such as N-arachidonoyl ethanolamide (Anandamide), N-arachidonoyl dopamine and others in an opportunistic fashion (PMID: 23178153). This signaling system has been shown to play a role in the physiological processes involved in inflammation (PMID: 25136293). Other N-acyl amides, including N-oleoyl-glutamine, have also been characterized as TRP channel antagonists (PMID: 29967167). N-acylamides have also been shown to have G-protein-coupled receptors (GPCRs) binding activity (PMID: 28854168). The study of N-acylamides is an active area of research and it is likely that many novel N-acylamides will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered for these molecules.
