The new imidazopyridopyrimidine:naphthyridine base-pairing motifs, ImO(O):NaN(N) and ImN(N):NaO(O), were designed. Among the base pairs examined, DNA duplexes containing ImN(N):NaO(O) pair(s) consisting of a DAAD:ADDA hydrogen bonding pattern (D = donor, A = acceptor) were markedly stabilized thermally and thermodynamically.
萘啶碱基配对基序,ImO(O):NaN(N) 和 ImN(N):NaO(O)。在所研究的碱基对中,包含由 DAAD:ADDA 氢键模式(D = 供体,A = 受体)组成的 ImN(N):NaO(O) 对的 DNA 双链体在热和热力学上显著稳定。
