7297-25-8O=[N+]([O-])OC[C@H](O[N+](=O)[O-])[C@@H](CO[N+](=O)[O-])O[N+](=O)[O-]SNFOERUNNSHUGP-ZXZARUISSA-NErythrityl tetranitrate is erythritol in which each of the hydroxy groups has been converted to the corresponding nitrate ester. It is a vasodilator with properties similar to nitroglycerin. It is usually used diluted with lactose or other suitable inert excipients, in order to minimise the risk of explosion; undiluted erythrityl tetranitrate can be exploded by percussion or excessive heat. It has a role as a vasodilator agent and an explosive. It is functionally related to an erythritol.
化学的特性Crystals. Soluble in alcohol, ether, and glycerol; insoluble in water.

Similar to other nitrites and organic nitrates, erythrityl tetranitrate is converted to an active intermediate compound which activates the enzyme guanylate cyclase. This stimulates the synthesis of cyclic guanosine 3',5'-monophosphate (cGMP) which then activates a series of protein kinase-dependent phosphorylations in the smooth muscle cells, eventually resulting in the dephosphorylation of the myosin light chain of the smooth muscle fiber. The subsequent release of calcium ions results in the relaxation of the smooth muscle cells and vasodilation.
使用Vasodilator (coronary). Cardilate (Glaxo Wellcome{) [Name previously used: Erythrol Tetranitrate.].
純化方法Crystallise cordite from EtOH. It explodes on percussion at ~220-460o and is a vasodilator. [Beilstein 1 III 2358, 1 IV 2809.]
