Aza analogs of pyrimidine and purine

Aza Analogs of Pyrimidine and Purine Bases of Nucleic Acids... [Pg.189]

An important group of antimetabolites are the aza analogs of pyrimidine and purine bases which are theoretically derived by a replacement of the methine group of a pyrimidine or purine nucleus with a nitrogen atom. This replacement represents a relatively minor alteration of the structure of these substances as it does not change the functional groups, practically preserves the molecular weight, and produces almost isosteric compounds. The replacement of the methine... [Pg.190]
