4-Guanidinobutanoic acid

4-[(diaminomethylidene)amino]butanoic acid

C5H11N3O2 (145.0851)


4-Guanidinobutanoic acid, also known as gamma-guanidinobutyrate or 4-(carbamimidamido)butanoate, belongs to the class of organic compounds known as gamma amino acids and derivatives. These are amino acids having a (-NH2) group attached to the gamma carbon atom. 4-Guanidinobutanoic acid is a normal metabolite present in low concentrations. 4-Guanidinobutanoic acid exists in all eukaryotes, ranging from yeast to humans. Outside of the human body, 4-Guanidinobutanoic acid has been detected, but not quantified in a few different foods, such as apples, french plantains, and loquats. This could make 4-guanidinobutanoic acid a potential biomarker for the consumption of these foods. Patients with hyperargininemia have an arginase deficiency which leads to blockade of the urea cycle in the last step with several clinical symptoms. Owing to the arginase deficiency this patients accumulate arginine which leads eventually to epileptogenic guanidino compounds (PMID 7752905). 4-guanidinobutanoic acid, also known as gamma-guanidinobutyrate or 4-(carbamimidamido)butanoate, belongs to gamma amino acids and derivatives class of compounds. Those are amino acids having a (-NH2) group attached to the gamma carbon atom. 4-guanidinobutanoic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). 4-guanidinobutanoic acid can be found in apple, french plantain, and loquat, which makes 4-guanidinobutanoic acid a potential biomarker for the consumption of these food products. 4-guanidinobutanoic acid can be found primarily in blood, cerebrospinal fluid (CSF), and urine, as well as in human prostate tissue. 4-guanidinobutanoic acid exists in all eukaryotes, ranging from yeast to humans. Moreover, 4-guanidinobutanoic acid is found to be associated with cirrhosis. CONFIDENCE standard compound; ML_ID 15 KEIO_ID G032 4-Guanidinobutanoic acid is a normal metabolite present in low concentrations. 4-Guanidinobutanoic acid is a normal metabolite present in low concentrations.

   

N8-Acetylspermidine

N-[4-[(3-Aminopropyl)amino]butyl]-acetamide

C9H21N3O (187.1685)


N8-Acetylspermidine is a polyamine. The polyamines, found in virtually all living organisms, are a ubiquitous group of compounds that appear to play a vital role in many cellular processes involving nucleic acids including cell growth and differentiation. The polyamines, found in virtually all living organisms, are a ubiquitous group of compounds that appear to play a vital role in many cellular processes involving nucleic acids including cell growth and differentiation. Acetylation on the terminal nitrogen adjacent to the 4-carbon chain produces N8-acetylspermidine. This reaction is catalyzed by spermidine N8-acetyltransferase and does not result in the conversion of spermidine to putrescine but, instead, the product undergoes deacetylation. This acetyltransferase appears to be associated with chromatin in the cell nucleus and has been reported to be the same as (or related to) the enzyme(s) responsible for histone acetylation. N8-Acetylspermidine does not accumulate in tissues but rather appears to be rapidly deacetylated back to spermidine by a relatively specific cytosolic deacetylase, N8-acetylspermidine deacetylase. The function of this N8-acetylation/deacetylation pathway in cellular processes is not understood clearly, but several observations have suggested a role in cell growth and differentiation.

Carbimazole

ethyl 3-methyl-2-sulfanylidene-2,3-dihydro-1H-imidazole-1-carboxylate

C7H10N2O2S (186.0463)


Carbimazole is only found in individuals that have used or taken this drug. It is an imidazole antithyroid agent. Carbimazole is metabolized to methimazole, which is responsible for the antithyroid activity. [PubChem]Carbimazole is an aitithyroid agent that decreases the uptake and concentration of inorganic iodine by thyroid, it also reduces the formation of di-iodotyrosine and thyroxine. Once converted to its active form of methimazole, it prevents the thyroid peroxidase enzyme from coupling and iodinating the tyrosine residues on thyroglobulin, hence reducing the production of the thyroid hormones T3 and T4.

Diethylthiophosphate

O,O-Diethyl phosphorothionate, potassium salt

C4H11O3PS (170.0167)


Diethylthiophosphate, also known as DETP, belongs to the class of organic compounds known as thiophosphate diesters. These are organic compounds containing the thiophosphoric acid functional group or a derivative thereof, with the general structure ROP(OR)(OR)=S, where exactly two R-groups are organyl groups. The glutathione transferase reactions produce products that are, in most cases, of low toxicity. Diethylthiophosphate is a potentially toxic compound. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase Chronic exposure to POs has neurological sequelae as well and data suggests that OP exposure alters sperm chromatin condensation (A3181, A3182, A3183, A3181). Chronic exposure to POs has neurological sequelae as well (PMID 8179040) and data suggests that OP exposure alters sperm chromatin condensation (PMID 15050412). PON1 hydrolyzes the active metabolites in several organophosphates insecticides as well as, nerve agents such as soman, sarin, and VX. Metabolism of organophosphates occurs principally by oxidation, by hydrolysis via esterases and by reaction with glutathione. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase (PMID 11991535). Diethylthiophosphate is the most frequent metabolite of organophosphorus (OP) found in urine (PMID 15050412). Organophosphorus compounds are widely used as pesticides because of easy degradation in the environment. Acute OP intoxication results from blockage of the decomposition of synaptic acetylcholine because the pesticide covalently binds to chlolinesterase (PMID 11991535). Chronic exposure to POs has neurological sequelae as well (PMID 8179040) and data suggests that OP exposure alters sperm chromatin condensation (PMID 15050412) [HMDB] KEIO_ID D113

Thiamylal

Dihydro-5-(1-methylbutyl)-5-(2-propenyl)-2-thioxo-4,6(1H,5H)-pyrimidinedione

C12H18N2O2S (254.1089)


Thiamylal is only found in individuals that have used or taken this drug. It is a barbiturate that is administered intravenously for the production of complete anesthesia of short duration, for the induction of general anesthesia, or for inducing a hypnotic state. (From Martindale, The Extra Pharmacopoeia, 30th ed, p919)Thiamylal binds at a distinct binding site associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.
