A new class of shape-modified nucleosides is introduced. These novel "fleximers" feature the purine ring systems of adenosine, inosine, and guanosine split into their individual imidazole and pyrimidine components (as in 1-3). This structural modification serves to introduce flexibility into the nucleoside while still retaining the elements essential for recognition. As a consequence, these novel fleximers

surprising then that modified purines possess the potential to impact several areas, including a better understanding of the biological effects of DNA damaging agents, enzyme/substrate interactions, and in the development of more potent medicinal agents. One focus for our research at Georgia Tech has centered around the design and synthesis of a series of extended purine analogues containing a heterocyclic
