Cytosine-containing hybrid dipeptides: N-[2-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)propionyl]-L-phenylalanine N-[2-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)propionyl]-L-serine monohydrate and N-[2-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)propionyl]-L-lysine.

Abstract

The title compounds are cytosine-incorporating hybrid dipeptides showing affinities for 9-ethyl-7-methylguanine (7mG). Four molecules of the L-phenylalanine (L-Phe) derivative, C16H14N4O4, are present in the asymmetric unit, with similar folded conformations but with slightly different torsion angles involving the L-Phe group. The L-serine (L-Ser… (More)
