Abstract
The antibiotics which resemble adenosine comprise a growing family of nucleosides with unique structures and diverse actions. Only selected members can be considered here, with emphasis on the relation of structure to metabolism and locus of action. As analogs of adenosine, these cytotoxic agents have useful application to studies exploring binding sites of adenine nucleotides and structural features of polynucleotide polymers. As more information emerges it will be feasible to classify these nucleosides, along with synthetic relatives, according to their sites of action. In this regard, a broad distinction can be made separating this family of adenosine related nucleosides from other nucleoside antibiotics, which bind at ribosomal sites to inhibit protein synthesis and which, like puromycin, bear substituents that classify them as analogs of aminoacyl-tRNA.
