Ciprofloxacin

1-Cyclopropyl-6-fluoro-7-(4-methyl-piperazin-1-yl)-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid

C17H18FN3O3 (331.1332)


Ciprofloxacin is only found in individuals that have used or taken this drug. It is a broad-spectrum antimicrobial carboxyfluoroquinoline.The bactericidal action of ciprofloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV, which are required for bacterial DNA replication, transcription, repair, strand supercoiling repair, and recombination.

C18H21NO5 (331.142)


Pretazettine, also known as pretazettine hydrochloride, (6abeta,8beta)-isomer, is a member of the class of compounds known as tazettine-type amaryllidaceae alkaloids. Tazettine-type amaryllidaceae alkaloids are amaryllidaceae alkaloids derived from the haemanthamine-type alkaloids, which are characterized as a linkage between C6 and C11 by an oxygen atom to form a [3,4-g]benzopyran framework. Pretazettine is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Pretazettine can be found in lovage, which makes pretazettine a potential biomarker for the consumption of this food product.

{1-[(carboxylatomethyl)carbamoyl]-2-[(4-hydroxy-1-oxononan-3-yl)sulfanyl]ethyl}azaniumyl

C14H23N2O5S (331.1328)


4-hydroxy-2-nonenal-[cys-gly] conjugate is a member of the class of compounds known as N-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. 4-hydroxy-2-nonenal-[cys-gly] conjugate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 4-hydroxy-2-nonenal-[cys-gly] conjugate can be found in a number of food items such as persian lime, silver linden, black raspberry, and nutmeg, which makes 4-hydroxy-2-nonenal-[cys-gly] conjugate a potential biomarker for the consumption of these food products.
