Norfloxacin

1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid

C16H18FN3O3 (319.1332)

Norfloxacin is only found in individuals that have used or taken this drug. It is a synthetic fluoroquinolone (fluoroquinolones) with broad-spectrum antibacterial activity against most gram-negative and gram-positive bacteria. Norfloxacin inhibits bacterial DNA gyrase. [PubChem]The bactericidal action of Norfloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, and recombination. Norfloxacin is a broad-spectrum antibiotic that is active against both gram-positive and gram-negative bacterias. The fluorine atom at the 6 position increases potency against gram-negative organisms, and the piperazine moiety at the 7 position is responsible for anti-pseudomonal activity J - Antiinfectives for systemic use > J01 - Antibacterials for systemic use > J01M - Quinolone antibacterials > J01MA - Fluoroquinolones D004791 - Enzyme Inhibitors > D065607 - Cytochrome P-450 Enzyme Inhibitors > D065609 - Cytochrome P-450 CYP1A2 Inhibitors D000970 - Antineoplastic Agents > D059003 - Topoisomerase Inhibitors > D059005 - Topoisomerase II Inhibitors S - Sensory organs > S01 - Ophthalmologicals > S01A - Antiinfectives > S01AE - Fluoroquinolones D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents > D024841 - Fluoroquinolones C254 - Anti-Infective Agent > C258 - Antibiotic > C795 - Quinolone Antibiotic CONFIDENCE standard compound; EAWAG_UCHEM_ID 232 CONFIDENCE standard compound; INTERNAL_ID 1032

C15H17N3O5 (319.1168)

Tryptophyl-Aspartate is a dipeptide composed of tryptophan and aspartate. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

Salbutamol 4-O-sulfate

{4-[2-(tert-butylamino)-1-hydroxyethyl]-2-(hydroxymethyl)phenyl}oxidanesulfonic acid

C13H21NO6S (319.109)

Salbutamol 4-O-sulfate is a metabolite of salbutamol. Salbutamol or albuterol is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease. It is marketed as Ventolin among other brand names. Salbutamol was the first selective β2-receptor agonist to be marketed — in 1968. It was first sold by Allen & Hanburys under the brand name Ventolin. The drug was an instant success, and has been used for the treatment of asthma ever since. (Wikipedia)

(2S)-2-Hydroxy-2-(propan-2-yl)butanedioylcarnitine

3-{[3-carboxy-3-hydroxy-3-(propan-2-yl)propanoyl]oxy}-4-(trimethylazaniumyl)butanoate

C14H25NO7 (319.1631)

(2S)-2-hydroxy-2-(propan-2-yl)butanedioylcarnitine is an acylcarnitine. More specifically, it is an (2S)-2-hydroxy-2-(propan-2-yl)butanedioic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. (2S)-2-hydroxy-2-(propan-2-yl)butanedioylcarnitine is therefore classified as a medium chain AC. As a medium-chain acylcarnitine (2S)-2-hydroxy-2-(propan-2-yl)butanedioylcarnitine is somewhat less abundant than short-chain acylcarnitines. These are formed either through esterification with L-carnitine or through the peroxisomal metabolism of longer chain acylcarnitines (PMID: 30540494). Many medium-chain acylcarnitines can serve as useful markers for inherited disorders of fatty acid metabolism. Carnitine octanoyltransferase (CrOT, EC:2.3.1.137) is responsible for the synthesis of all medium-chain (MCAC, C5-C12) and medium-length branched-chain acylcarnitines in peroxisomes (PMID: 10486279). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].
