  NOVEL CLASS OF DNA BINDING MOTIFS BASED ON BISTETRAHYDROFURAN AND BISFURAN SKELETON WITH LONG ALKYL CHAINS

  摘要：

  Small molecules with DNA-binding affinity within the minor groove have become of great interest. In this paper, new DNA binding molecules; diamino-bistetrahydrofuran (bisTHF) and diamino-bisfuran are reported. The bisTHF ligand with RR configuration at the amino groups and C8 alkyl chains (RR8) stabilized GC-rich duplex. In contrast, bisfuran compounds stabilized AT-rich duplex. The binding affinity of RR8 with 12 mer duplex DNA was determined by isothermal titration calorimetry to be 3.3 x 10(8) M-1.

  Novel acyclic ligands for metal cations based on the adjacent bistetrahydrofuran as analogs of natural Annonaceous acetogenins

  摘要：

  The acyclic ligands with an adjacent bistetrahydrofuran (THF) skeleton have been synthesized as analogs of bullatacin, a representative natural product in a family of Annonaceous acetogenins, and their binding properties toward metal cations have been investigated. The dihydroxyl bis-THF ligands with alkyl chains showed specific binding toward Ca2+, and those with acetamido groups exhibited potent binding with Ca2+ and Mg2+. The ligand with ether chains showed higher affinity toward Mg2+. These binding properties which depend on the nature of side chains and their stereochemistry have been analyzed by molecular modeling.
