title: trans-5-aminopipecolyl-aegPNA chimera: design, synthesis, and study of binding preferences with DNA/RNA in duplex/triplex mode.
abstract: The design and synthesis of novel chiral PNA monomer based on trans-5-aminopipecolic acid is reported. The trans diequatorial disposition of the 1,4 ring substituents in six-membered 5-aminopipecolic acid derivative could be favorable over trans 1,3 axial-equatorial disposition in 4-aminopipecolic acid of PNA. Studies on the synthesis of trans-4/5-aminopipecolyl PNA-eagPNA chimeras and their binding preferences to DNA/RNA in duplex/triplex modes are described.
