Peptides of DL-willardiine. homo- and heterodipeptides from willardiine

One of the types of pyurinylpeptides (i.e., peptides constructed of pyrimidyl-and purinyl--amino acids) consists of peptides including residues of only those -amino acids the lateral radicals of which contain nucleic bases. Below, such amino acids will be called nucleoamino acids and the peptides derived from them nucleopeptides. The latter are hybrid analogs of nucleic acids and proteins. Their study may lead to important theoretical and practical results.Translated from Khimiya Geterotsiklicheskikh Soedinenii, Vol. 6, No. 7,pp. 1002–1003, July, 1970.We are continuing the synthesis and study of the properties of the pyurinylpeptides and nucleopeptides.
