title: [Alkylation of nucleic acid components by ethyleneimine derivatives. I. Alkylation of bases].
abstract: In the course of investigating the reaction conditions of the nucleic acid components alcylation, the interaction of thioTEPA (N,N',N''-triethylenethiophosphoamide) with hydrochloric and perchloric acids was studied, perchloric acid increasing the alkylation products yield. HPLC and UV spectroscopy were used to isolate and identify products of nucleic bases alkylation by ethylenimine and its derivatives (thioTEPA and monoaziridinediethylphosphate). It is shown that under neutral conditions phosphoaminoethylation takes place, whereas under slightly acidic conditions products of aminoethylation are formed.
