  Synthesis and hybridization properties of the conjugates of oligonucleotides and stabilization agents. Part 3☆

  摘要：

  New compounds having tri- or pentamethylenamine linker functions were synthesized. These derivatives were covalently attached through the 5'-phosphoramide linkage to heptanucleotide pd(CCAAACA). Complementary complexes of the octanucleotide pd(TGTTTGGC) and above oligonucleotide conjugates were tested for their thermodynamic response. The T-m data and thermodynamic parameters for complex formation confirmed the ability of chromone (gamma-pyrone) derivatives to stabilize strongly the 7-mer/8-mer complementary complex. Moreover, benzochromone (naphthopyrane) and, surprisingly, tetrallydropyrimidinethanone derivatives showed the capacity of stabilizing this 7-mer/8-mer complementary complex. The effect of all these compounds on the stability of the oligonucleotide complexes (DeltaG at 37degreesC ranged from - 1.2 to -2.0 kcal/mol) was shown to be comparable to the effect of one nucleotide base pair and similar to the effect (DeltaDeltaG at 37degreesC ranged from -1.5 to -2.0 kcal/mol) found for acridine-oligonucleotide conjugates, which served as a reference in this study.

  The title compounds were advantageously synthesized from 2-(dialkylamino)chromones and 1,3-diaminopropane (or 1-amino-3-bromopropane) by amine exchange. The 3-cyano derivatives 5 were directly prepared from 2-(dimethylamino)chromones 1 and KCN by nitro displacement.
