Peptide Nucleic Acid with Double Face: Homothymine-Homocytosine Bimodal C alpha-PNA (bm-C alpha-PNA) Forms a Double Duplex of the bm-PNA(2):DNA Triplex
C alpha-bimodal peptide nucleic acids (bm-C alpha-PNA) are PNAs with two faces and are designed homologues of PNAs in which each aminoethylglycine (aeg) repeating unit in the standard PNA backbone hosts a second nucleobase at C alpha through a spacer chain with a triazole linker. Such bm-C alpha-PNA with mixed sequences can form double duplexes by simultaneous binding to two complementary DNAs, one to the base sequence on t-amide side and the other to the bases on the C alpha side chain. The synthesis of bm-C alpha-PNA with homothymine (T-7) on the t-amide face and homocytosine (C-5) on the C alpha side chain through the triazole linker was achieved by solid phase synthesis with the global click reaction. In the presence of complementary DNAs dA(8) and dG(6) at neutral pH, bm-C alpha-PNA 1 forms a higher order pentameric double duplex of a triplex composed of two bmC alpha-PNA-C-5:dG(5) duplexes built on a core (bm-Ca-PNA-T-7)(2):dA(8) triplex. Circular dichroism studies showed that assembly can be achieved by either triplex first and duplex later or vice versa. Isothermal titration calorimetry data indicated that the assembly is driven by favorable enthalpy. These results validate concurrent multiple complex formation by bimodal PNAs with additional nucleobases at C alpha or C gamma on the aeg-PNA backbone and open up ways to design programmed supramolecular assemblies.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5445-51-2, you can contact me at any time and look forward to more communication. COA of Formula: C6H8O4.
