Phosphoserine

(S)-2-Amino-3-hydroxypropanoic acid 3-phosphoric acid

C3H8NO6P (185.0089238)

The phosphoric acid ester of serine. As a constituent (residue) of proteins, its side chain can undergo O-linked glycosylation. This might be important in explaining some of the devastating consequences of diabetes. It is one of three amino acid residues that are commonly phosphorylated by kinases during cell signalling in eukaryotes. Phosphorylated serine residues are often referred to as phosphoserine. Serine proteases are a common type of protease. Serine, organic compound, one of the 20 amino acids commonly found in animal proteins. Only the L-stereoisomer appears in mammalian protein. It is not essential to the human diet, since it can be synthesized in the body from other metabolites, including glycine. Serine was first obtained from silk protein, a particularly rich source, in 1865. Its name is derived from the Latin for silk, sericum. Serines structure was established in 1902. [HMDB] Phosphoserine is the phosphoric acid ester of the amino acid serine. It is found in essentially all living organisms ranging from microbes to plants to mammals. Phosphoserine is a component of many proteins as the result of posttranslational modifications to the native protein‚Äôs serine residue(s). The phosphorylation of the hydroxyl functional group in serine to produce phosphoserine is catalyzed by various types of kinases. Serine is one of three amino acid residues that are commonly phosphorylated by kinases during cell signalling in eukaryotes. Free phosphoserine is found in many biofluids and likely arises from the proteolysis of proteins containing phosphoserine residues (PMID: 7693088).

KEIO_ID P060 DL-O-Phosphoserine, a normal metabolite in human biofluid, is an ester of serine and phosphoric acid.

2-Amino-3-carboxymuconic acid semialdehyde

(2Z)-2-amino-3-[(1Z)-3-oxoprop-1-en-1-yl]but-2-enedioic acid

C7H7NO5 (185.0324212)

2-Amino-3-carboxymuconic acid semialdehyde (CAS: 16597-58-3) is an intermediate metabolite of the tryptophan-niacin catabolic pathway. Current interest in the degradation of tryptophan is mostly due to the role of quinolinate and other metabolites in several neuropathological conditions. Quinolinate is a neurotoxin formed nonenzymatically from 2-amino-3-carboxymuconic semialdehyde in mammalian tissues. 2-Amino-3-carboxymuconic acid semialdehyde is enzymatically converted into 2-aminomuconate via 2-aminomuconic semialdehyde (PMID: 10510494, 16267312, 14275129). 2-amino-3-carboxymuconic acid semialdehyde is an intermediate metabolite of the tryptophan-niacin catabolic pathway.

3-phospho-L-serine

(2R)-2-Amino-3-(phosphonooxy)propanoic acid

C3H8NO6P (185.0089238)

O-phospho-d-serine, also known as (2r)-2-amino-3-(phosphonooxy)propanoic acid, is a member of the class of compounds known as D-alpha-amino acids. D-alpha-amino acids are alpha amino acids which have the D-configuration of the alpha-carbon atom. O-phospho-d-serine is soluble (in water) and a moderately acidic compound (based on its pKa). O-phospho-d-serine can be found in a number of food items such as mugwort, rambutan, common persimmon, and ostrich fern, which makes O-phospho-d-serine a potential biomarker for the consumption of these food products. O-phospho-d-serine may be a unique E.coli metabolite.

C7H4ClNO3 (184.9879704)

6-hydroxychlorzoxazone is a metabolite of chlorzoxazone. Chlorzoxazone is a centrally acting muscle relaxant used to treat muscle spasm and the resulting pain or discomfort. It acts on the spinal cord by depressing reflexes. It is sold as Muscol or Parafon Forte, a combination of chlorzoxazone and acetaminophen (Paracetamol). Possible side effects include dizziness, lightheadedness, malaise, nausea, vomiting, and liver dysfunction. Used with acetaminophen it has added risk of hepatoxicity, which is why the combination is not recommended. (Wikipedia)

DL-O-Phosphoserine

DL-Serine, dihydrogen phosphoric acid (ester)

C3H8NO6P (185.0089238)

DL-O-Phosphoserine, also known as DL-O-phosphorylserine or DL-O-serine phosphate, belongs to the class of organic compounds known as alpha amino acids.

Enaminomycin C

2,5-dihydroxy-4-imino-7-oxabicyclo[4.1.0]hept-2-ene-3-carboxylic acid

C7H7NO5 (185.0324212)

Enaminomycin C is a metabolite that has been isolated from Streptomyces species, which are a group of bacteria known for their ability to produce a wide array of secondary metabolites with diverse biological activities. Enaminomycin C is one such compound that has been identified and characterized from these bacteria. It belongs to the enediyne antibiotic class, which are complex natural products known for their potent antibacterial activity, particularly against Gram-positive bacteria. Enaminomycin C, like other enediyne antibiotics, is believed to exert its antibacterial effects by targeting the bacterial ribosome and forming a complex with the RNA, leading to the inhibition of protein synthesis and ultimately cell death. The structural features of Enaminomycin C contribute to its unique biological properties. It possesses an enediyne core, which is a key structural element responsible for its antibacterial activity. Additionally, it may have other functional groups or substituents that can influence its pharmacological properties, such as absorption, distribution, metabolism, and excretion. As a natural product with potential antimicrobial activity, Enaminomycin C and other related compounds have been of interest in the field of drug discovery and development. Researchers are interested in understanding their mechanisms of action, as well as exploring the potential for modifying these compounds to improve their therapeutic profiles, such as increasing potency, reducing toxicity, or expanding the spectrum of activity against drug-resistant bacteria. However, it is important to note that while Enaminomycin C has been identified and characterized from Streptomyces species, it may not have been extensively studied or developed into a therapeutic agent. Further research is needed to fully understand its potential as a novel antimicrobial agent and to address any challenges associated with its development, such as synthesis, scalability, and clinical trials.
