Metronidazole
A nitroimidazole used to treat amebiasis; vaginitis; trichomonas infections; giardiasis; anaerobic bacteria; and treponemal infections. It has also been proposed as a radiation sensitizer for hypoxic cells. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985, p133), this substance may reasonably be anticipated to be a carcinogen (Merck, 11th ed).

Tetrahydrodipicolinate
Tetrahydrodipicolinate (CAS: 2353-17-5), converted from L-aspartate, is an important intermediate in the lysine biosynthesis pathway. Several pathways are now recognized in bacteria, most algae, fungi, and higher plants for the biosynthesis of lysine. They are divided into two groups: (1) the diaminopimelate (DAP) pathways, and (2) the alpha-aminoadipate (AAA) pathways. In the pathways that belong to the DAP group, lysine is produced from aspartate (along with methionine, threonine, and isoleucine). All of these pathways share the upper segments, which include the four steps required for the conversion of L-aspartate into tetrahydrodipicolinate. They also share the last step, which is the conversion of the intermediate meso-diaminopimelate (D,L-DAP, or meso-DAP) into lysine. However, these pathways differ in the routes leading from tetrahydrodipicolinate to meso-diaminopimelate. The four variations include: (I) the succinylase variant, which involves succinylated intermediates, where tetrahydrodipicolinate is converted into meso-diaminopimelate in four enzymatic steps; (II) the acetylase variant, which involves acetylated intermediates, where tetrahydrodipicolinate is converted into meso-diaminopimelate in four enzymatic steps; (III) the dehydrogenase variant, in which tetrahydrodipicolinate is converted into meso-diaminopimelate in a single enzymatic step; and (IV) the diaminopimelate-aminotransferase variant, in which tetrahydrodipicolinate is converted into meso-diaminopimelate in two steps. In addition to lysine, the pathways in this group also produce meso-DAP, which is an important metabolite on its own.

1-naphthoate
1-naphthoate, also known as 1-naphthoic acid, is a member of the class of compounds known as naphthalenecarboxylic acids. Naphthalenecarboxylic acids are compounds containing a naphthalene moiety, which bears a carboxylic acid group one or more positions. Naphthalene is a bicyclic compound that is made up of two fused benzene ring. 1-naphthoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). 1-naphthoate can be found in a number of food items such as coconut, mountain yam, broad bean, and kombu, which makes 1-naphthoate a potential biomarker for the consumption of these food products.

metronidazole
A member of the class of imidazoles substituted at C-1, -2 and -5 with 2-hydroxyethyl, nitro and methyl groups respectively. It has activity against anaerobic bacteria and protozoa, and has a radiosensitising effect on hypoxic tumour cells. It may be given by mouth in tablets, or as the benzoate in an oral suspension. The hydrochloride salt can be used in intravenous infusions. Metronidazole is a prodrug and is selective for anaerobic bacteria due to their ability to intracellularly reduce the nitro group of metronidazole to give nitroso-containing intermediates. These can covalently bind to DNA, disrupting its helical structure, inducing DNA strand breaks and inhibiting bacterial nucleic acid synthesis, ultimately resulting in bacterial cell death.
