4-Nitrocatechol

4-nitro-Pyrocatechol4-nitropyrocatechol NSC 80651

C6H5NO4 (155.021857)


4-Nitrocatechol is the by-product of the hydroxylation of 4-Nitrophenol by the human cytochrome P450 (CYP) 2E1. This reaction is a useful metabolic marker for the presence of functional cytochrome P450 2E1 in mammalian cell microsomes. Hepatic and extrahepatic microsomal cytochrome P450 isozymes further catalyze the reduction of p-nitrocatechol to p-aminophenol.

Mechlorethamine

Merck frosst brand OF mechlorethamine hydrochloride

C5H11Cl2N (155.02685060000002)


Mechlorethamine is only found in individuals that have used or taken this drug. It is a vesicant and necrotizing irritant destructive to mucous membranes. It was formerly used as a war gas. The hydrochloride is used as an antineoplastic in Hodgkins disease and lymphomas. It causes severe gastrointestinal and bone marrow damage. [PubChem]Alkylating agents work by three different mechanisms: 1) attachment of alkyl groups to DNA bases, resulting in the DNA being fragmented by repair enzymes in their attempts to replace the alkylated bases, preventing DNA synthesis and RNA transcription from the affected DNA, 2) DNA damage via the formation of cross-links (bonds between atoms in the DNA) which prevents DNA from being separated for synthesis or transcription, and 3) the induction of mispairing of the nucleotides leading to mutations. Mechlorethamine is cell cycle phase-nonspecific.

C7H7O4- (155.0344322)


6-hydroxy-2-cyclohexen-one-carboxylate, also known as hcc, is a member of the class of compounds known as cyclohexenones. Cyclohexenones are compounds containing a cylohexenone moiety, which is a six-membered aliphatic ring that carries a ketone and has one endocyclic double bond. 6-hydroxy-2-cyclohexen-one-carboxylate is soluble (in water) and a weakly acidic compound (based on its pKa). 6-hydroxy-2-cyclohexen-one-carboxylate can be found in a number of food items such as avocado, bitter gourd, endive, and pepper (c. frutescens), which makes 6-hydroxy-2-cyclohexen-one-carboxylate a potential biomarker for the consumption of these food products.
