摘要：
In an effort to develop an orthogonal third base pair for the storage of genetic information, thiophene and furan heterocycles have been examined as nucleobase analogues. The stability of the unnatural bases was evaluated in duplex DNA paired opposite other unnatural bases as well as opposite the natural bases. Several unnatural base pairs are identified that are both reasonably stable and strongly selective against mispairing with native bases. These results expand the potential nucleobase analogues with which the genetic alphabet may be expanded to include five-membered-ring heterocycles.
