All Stories

  1. β,γ-Bis-substituted PNA with configurational and conformational switch: preferred binding to cDNA/RNA and cell-uptake studies
  2. Unimolecular antiparallel G-quadruplex folding topology of 2′–5′-isoTBA sequences remains unaltered by loop composition
  3. Ene-nucleic acids: a different paradigm to DNA chemistry
  4. Functional isoDNA aptamers: modified thrombin binding aptamers with a 2′-5′-linked sugar-phosphate backbone (isoTBA)
  5. Synthesis and structural studies of S-type/N-type-locked/frozen nucleoside analogues and their incorporation in RNA-selective, nuclease resistant 2′–5′ linked oligonucleotides
