Summary

1-(2-Carboxyethyl)-2-thiothymine was activated in the form of a N-hydroxysuccinimide ester. The free amino groups of poly (L-ornithine), poly(L-lysine) and isopoly(L-lysine) were acylated with this activated ester, and the resulting poly(nucleoamino acids) were characterized by means of elemental analyses, optical rotation, viscosities 1H- and 13C-NMR spectra. IR-spectra suggest that the poly(L-ornithine) and poly(L-lysine) derivatives adopt the α-helix structure in the solid state.
