  Stabilizing a DNA Three-Way Junction by Insertion of N4-Aryl-2-deoxy-5-methylcytidines.

  摘要：

  4,4'-Dimethoxytrityl and acetyl sugar protected alpha and beta thymidines are converted into the corresponding N-4-aryl-2-deoxy-5-methylcytidines via 4-(2,4,6-trimethylbenzenesulfonyloxy) pyrimidin-2(1H)-one nucleosides. These compounds were used for DNA synthesis after deacetylation and phosphitylation. Increased melting temperatures (6.2-9.6 degrees C) of three-way junctions (TWJ) were observed when N-4-(2-anilinophenyl)-, N-4-(2-benzylphenyl)- or N-4-(2-fluorenyl)-2-deoxy-5-methylcytidines were inserted into the middle of the junction region. A 26.6 degrees C increase in melting temperature was observed using a nucleosides in one of the strands of TWJ and with insertion of 2-deoxy-N-4-(2-fluorenyl)-5-methyl-alpha-cytidine at the junction. A large increase in thermal melting (18.8 degrees C) of the TWJ was also observed when 2-deoxy-5-methyl-N-4-(4-phenoxyphenyl)-alpha-cytidine was inserted at the junction as a chimeric nucleoside into a strand of beta nucleosides.
