Hydrogen cyanide
Hydrogen cyanide (with the historical common name of Prussic acid) is a chemical compound with chemical formula HCN. It is a colorless, extremely poisonous liquid that boils slightly above room temperature at 26 °C (79 °F). Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. A minor tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a pKa of 9.2. It partly ionizes in water solution to give the cyanide anion, CN.

Prostaglandin E3
Prostaglandin E3 is from the cyclooxygenase metabolism of eicosapentaenoic acid.Prostaglandins are eicosanoids. The eicosanoids consist of the prostaglandins (PGs), thromboxanes (TXs), leukotrienes (LTs), and lipoxins (LXs). The PGs and TXs are collectively identified as prostanoids. Prostaglandins were originally shown to be synthesized in the prostate gland, thromboxanes from platelets (thrombocytes), and leukotrienes from leukocytes, hence the derivation of their names. All mammalian cells except erythrocytes synthesize eicosanoids. These molecules are extremely potent, able to cause profound physiological effects at very dilute concentrations. All eicosanoids function locally at the site of synthesis, through receptor-mediated G-protein linked signalling pathways. Prostaglandin E3 is from the cyclooxygenase metabolism of eicosapentaenoic acid.

Hydrogen cyanide
A one-carbon compound consisting of a methine group triple bonded to a nitrogen atom D009676 - Noxae > D011042 - Poisons > D002619 - Chemical Warfare Agents Hydrogen cyanide, also known as hydrocyanic acid or cyanide, is a member of the class of compounds known as nitriles. Nitriles are compounds having the structure RC#N; thus C-substituted derivatives of hydrocyanic acid, HC#N. Hydrogen cyanide is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Hydrogen cyanide can be found in a number of food items such as kiwi, java plum, yellow wax bean, and mamey sapote, which makes hydrogen cyanide a potential biomarker for the consumption of these food products. Hydrogen cyanide exists in all living organisms, ranging from bacteria to humans. Hydrogen cyanide is a non-carcinogenic (not listed by IARC) potentially toxic compound. Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and inflammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F). HCN is produced on an industrial scale and is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals . Antidotes to cyanide poisoning include hydroxocobalamin and sodium nitrite, which release the cyanide from the cytochrome system, and rhodanase, which is an enzyme occurring naturally in mammals that combines serum cyanide with thiosulfate, producing comparatively harmless thiocyanate. Oxygen therapy can also be administered (L97) (T3DB).
