Nitrogen mustard
Nitrogen mustards are cytotoxic organic compounds with the chloroethylamine ((ClCH2)2NR2) functional group. Although originally produced as chemical warfare agents, they were the first chemotherapeutic agents for treatment of cancer. Nitrogen mustards are nonspecific DNA alkylating agents. Nitrogen mustards are not related to the mustard plant or its pungent essence, allyl isothiocyanate; the name comes from the pungent smell of chemical weapons preparations.
Halabja
Halabja (Helebce, حلبجة) is a city in the Kurdistan Region of Iraq and the capital of Halabja Governorate, located about northeast of Baghdad and from the Iranian border. The city lies at the base of what is often referred to as the greater Hewraman region stretching across the Iran–Iraq border. Halabja is surrounded by Hawraman and Shnrwe range in the northeast, Balambo range in the south and Sirwan river in the west. The Kurds in the city of Halabja generally speak only the Sorani dialect of Kurdish, but some residents of the surrounding villages speak the Hewrami dialect.
M114 155 mm howitzer
The M114 is a towed howitzer developed and used by the United States Army. It was first produced in 1942 as a medium artillery piece under the designation of 155 mm Howitzer M1. It saw service with the US Army during World War II, the Korean War, and the Vietnam War, before being replaced by the M198 howitzer. The gun was also used by the armed forces of many nations. The M114A1 remains in service in some countries.
Sulfonium
In organic chemistry, a sulfonium ion, also known as sulphonium ion or sulfanium ion, is a positively-charged ion (a "cation") featuring three organic substituents attached to sulfur. These organosulfur compounds have the formula . Together with a negatively-charged counterion, they give sulfonium salts. They are typically colorless solids that are soluble in organic solvent. Sulfonium compounds are usually synthesized by the reaction of thioethers with alkyl halides.
Alkylating antineoplastic agent
An alkylating antineoplastic agent is an alkylating agent used in cancer treatment that attaches an alkyl group (CnH2n+1) to DNA. The alkyl group is attached to the guanine base of DNA, at the number 7 nitrogen atom of the purine ring. Since cancer cells, in general, proliferate faster and with less error-correcting than healthy cells, cancer cells are more sensitive to DNA damage—such as being alkylated. Alkylating agents are used to treat several cancers.
Tabun (nerve agent)
Tabun or GA is an extremely toxic synthetic organophosphorus compound. It is a clear, colorless, and tasteless liquid with a faint fruity odor. It is classified as a nerve agent because it fatally interferes with normal functioning of the mammalian nervous system. Its production is strictly controlled and stockpiling outlawed by the Chemical Weapons Convention of 1993. Tabun is the first of the G-series nerve agents along with GB (sarin), GD (soman) and GF (cyclosarin). Although pure tabun is clear, less-pure tabun may be brown.
