Etoposide is a beta-D-glucoside, a furonaphthodioxole and an organic heterotetracyclic compound. It has a role as an antineoplastic agent and a DNA synthesis inhibitor. It is functionally related to a podophyllotoxin and a 4-demethylepipodophyllotoxin. A semisynthetic derivative of podophyllotoxin that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle. Etoposide is a Topoisomerase Inhibitor. The mechanism of action of etoposide is as a Topoisomerase Inhibitor. Etoposide is a natural product found in Aspergillus porosus, Aspergillus alliaceus, and other organisms with data available. Etoposide is a semisynthetic derivative of podophyllotoxin, a substance extracted from the mandrake root Podophyllum peltatum. Possessing potent antineoplastic properties, etoposide binds to and inhibits topoisomerase II and its function in ligating cleaved DNA molecules, resulting in the accumulation of single- or double-strand DNA breaks, the inhibition of DNA replication and transcription, and apoptotic cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle. (NCI04) A semisynthetic derivative of podophyllotoxin that exhibits antitumor activity.

See also: Etoposide Phosphate (active moiety of). Etoposide, also known as vepesid or VP-16, belongs to the class of organic compounds known as podophyllotoxins. These are tetralin lignans in which the benzene moiety of the tetralin skeleton is fused to a 1,3-dioxolane and the cyclohexane is fused to a butyrolactone (pyrrolidin-2-one). Etoposide is a drug. Within humans, etoposide participates in a number of enzymatic reactions. In particular, etoposide can be converted into etoposide ortho-quinone; which is mediated by the enzymes prostaglandin g/h synthase 1 and prostaglandin g/h synthase 2. In addition, etoposide and uridine diphosphate glucuronic acid can be converted into etoposide glucuronide and uridine 5-diphosphate; which is mediated by the enzyme UDP-glucuronosyltransferase 1-1. In humans, etoposide is involved in etoposide metabolism pathway. Etoposide is formally rated as a carcinogen (by IARC 1) and is also a potentially toxic compound. Etoposide is used as a form of chemotherapy for cancers such as Kaposis sarcoma, Ewings sarcoma, lung cancer, testicular cancer, lymphoma, nonlymphocytic leukemia, and glioblastoma multiforme. It is given intravenously (IV) or orally in capsule or tablet form. It is believed to work by damaging DNA. Etoposide was approved for medical use in the United States in 1983. They can include low blood cell counts, vomiting, loss of appetite, diarrhea, hair loss, and fever.

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon. ADP belongs to the class of organic compounds known as purine ribonucleoside diphosphates. These are purine ribobucleotides with diphosphate group linked to the ribose moiety. It is an ester of pyrophosphoric acid with the nucleotide adenine. Adenosine diphosphate is a nucleotide. ADP exists in all living species, ranging from bacteria to humans. In humans, ADP is involved in d4-gdi signaling pathway. ADP is the product of ATP dephosphorylation by ATPases. ADP is converted back to ATP by ATP synthases.

Cyclizine

(N-Benzhydryl)(n-methyl)diethylenediamine

C18H22N2 (266.1783)


Cyclizine is only found in individuals that have used or taken this drug. It is a histamine H1 antagonist given by mouth or parenterally for the control of postoperative and drug-induced vomiting and in motion sickness. (From Martindale, The Extra Pharmacopoeia, 30th ed, p935)Vomiting (emesis) is essentially a protective mechanism for removing irritant or otherwise harmful substances from the upper GI tract. Emesis or vomiting is controlled by the vomiting centre in the medulla region of the brain, an important part of which is the chemotrigger zone (CTZ). The vomiting centre possesses neurons which are rich in muscarinic cholinergic and histamine containing synapses. These types of neurons are especially involved in transmission from the vestibular apparatus to the vomiting centre. Motion sickness principally involves overstimulation of these pathways due to various sensory stimuli. Hence the action of cyclizine which acts to block the histamine receptors in the vomiting centre and thus reduce activity along these pathways. Furthermore since cyclizine possesses anti-cholinergic properties as well, the muscarinic receptors are similarly blocked.

Phosphoglycolic acid can be found in a number of food items such as arrowhead, rocket salad (sspecies), roselle, and natal plum, which makes phosphoglycolic acid a potential biomarker for the consumption of these food products. Phosphoglycolic acid can be found primarily throughout most human tissues. Phosphoglycolic acid exists in all living species, ranging from bacteria to humans. Phosphoglycolic acid is a substrate for triose-phosphate isomerase. This compound belongs to the family of Organophosphate Esters.
