A route to RNA with an alkylating group at the 5'-triphosphate residue
Novosibirsk Institute of Organic Chemistry, Siberian Division of the Academy of Sciences Novosibirsk 90, USSR
Received May 15, 1980.
Reaction of ATP with N,N,N'-tris(2-chloroethyl),N'(p-formylphenyl)propylenediamine-1,3 (abbreviation Cl3R) afforded a
-ester of ATP (abbreviation CLRpppA)-the product of alkylation by an aliphatic nitrogen mustard residue of Cl3R. The alkylating activity of the aromatic nitrogen mustard residue of ClRpppA is suppressed by the electron-acceptor effect of the p-fomyl group. ClRpppA is a substrate of RNA-polymerase, and affords RNA with ClRpppA-residues at the 5'-termini.
