Janus bases are heterocyclic nucleic acid base analogs that present two different faces able to simultaneously hydrogenbond to nucleosides that form Watson–Crick base pairs. The synthesis of a Janus‐AT nucleotide analogue, NJAT, that has an additional endocyclic ring nitrogen and is thus more capable of efficiently discriminating T/A over G/C bases when base‐pairing in a standard duplex‐DNA context

Compositions or an assembly of a series of biomimetic compounds include chemical structures that mimic or structurally resemble a nucleic acid base pair. Complexes of nanotubes and agents are useful to deliver agents into the cells or bodily tissues of individuals for therapeutic and diagnostic purposes. Exemplary compounds include those of Formula (I), (III), (V) or (VII), or of Formula (II), (IV), (VI) or (VIII).

complementary to uracil/thymine. These heterocycles, which have never before been reported or characterized, represent diaminopurine−uracil/thymine hybrids that, in two of the three cases, relate to previously reported heterocyclic hybrids of G and C. All three heterocycles crystallized to afford the first X-ray crystalstructures of self-complementary heterocycles capable of ADA−DAD pairing. The potential
