Phosphorylethanolamine or phosphoethanolamine is an ethanolamine derivative that is used to construct two different categories of phospholipids. One category termed a glycerophospholipid and the other a sphingomyelin, or more specifically within the sphingomyelin class, a sphingophospholipid. Phosphorylethanolamine is a polyprotic acid with two pKa values at 5.61 and 10.39.

WebNov 12, 2007 · The phosphoranimine Br (CF3CH2O)2P=NSiMe3 (12) reacts quantitatively with nitrogen bases pyridine, 4,4'-bipyridine, and quinuclidine (quin) to form the N-donor stabilized phosphoranimine cations [N-donor.P (OCH2CF3)2=NSiMe3] ( [15]+) in the presence of the halide abstractor AgOTf.
WebAbstract. The reaction pathway of alkylating agents is often exploited in the design of bifunctional anti-cancer drugs. These drugs form mono-DNA adducts as well as inter- and intra-strand cross-linked adducts, notably by reaction at DNA bases, including the N-7-position of guanine (G).
