  Complexes of the [K(18-Crown-6)]⁺ Fragment with Bis(tetrazolyl)borate Ligands: Unexpected Boron−Nitrogen Bond Isomerism and Associated Enforcement of κ³-N,N′,H-Ligand Chelation

  摘要：

  The syntheses and solid-state structures of K(BH2(RCN4)(2))-(18-crown-6) (R = H, Me, NMe2, and NiPr2) are described. Complexes where R = H and Me have B-N bonds to N-1 of the tetrazolyl groups and form one-dimensional polymers, whereas those with R = NMe2 and NiPr2 possess isomeric B-N bonds to N-2 of the tetrazolyl moieties and adopt chelating kappa(3)-N,N',H-coordination modes to the potassium ion.

  2‘-O-Aminopropyl Ribonucleotides:  A Zwitterionic Modification That Enhances the Exonuclease Resistance and Biological Activity of Antisense Oligonucleotides

  摘要：

  Oligonucleotides containing 2'-O-aminopropyl-substituted RNA have been synthesized. The 2'-O-(aminopropyl)adenosine (APA), 2'-O-(aminopropyl)cytidine (APC), 2'-O-(aminopropyl)guanosine (APG), and 2'-O-(aminopropyl)uridine (APU) have been prepared in high yield from the ribonucleoside, protected, and incorporated into an oligonucleotide using conventional phosphoramidite chemistry. Molecular dynamics studies of a dinucleotide in water demonstrates that a short alkylamine located off the 2'-oxygen of ribonucleotides alters the sugar pucker of the nucleoside but does not form a tight ion pair with the proximate phosphate. A 5-mer with the sequence ACTUC has been characterized using NMR. As predicted from the modeling results, the sugar pucker of the APU moiety is shifted toward a C3'-endo geometry. In addition, the primary amine rotates freely and is not bound electrostatically to any phosphate group, as evidenced by the different sign of the NOE between sugar proton resonances and the signals from the propylamine chain. Incorporation of aminopropyl nucleoside residues into point-substituted and fully modified oligomers does not decrease the affinity for complementary RNA compared to 2'-O-alkyl substituents of the same length. However, two APU residues placed at the 3'-terminus of an oligomer gives a 100-fold increase in resistance to exonuclease degradation, which is greater than observed for phosphorothioate oligomers. These structural and biophysical characteristics make the 2'-O-aminopropyl group a leading choice for incorporation into antisense therapeutics. A 20-mer phosphorothioate oligonucleotide capped with two phosphodiester aminopropyl nucleotides targeted against C-raf mRNA has been transfected into cells via electroporation. This oligonucleotide has 5-10-fold greater activity than the control phosphorothioate for reducing the abundance of C-raf mRNA and protein.
