  A reinforced polyaza[n.n]paracyclophane containing piperazine rings

  摘要：

  The new [n.n]paraazacyclophane 3,7,10,14,21,25,28,32-octaazapentacyclo[32.2.2(7,10).2(25,28)]tetratetraconta-1 (37),16(41),17,19(40),34(38),35-hexaene (L) has been prepared. Its protonation has been studied by means of potentiometry and direct microcalorimetry in 0.15 mol dm (3) NaClO4 at 298.1 K. A NMR analysis shows that protons bind alternately at both sides of L, the benzylic nitrogens being the first sites to be protonated. From dynamic variable-temperature NMR analysis an activation enthalpy of 61(2) kJ mol (1) has been derived for the chair-chair interconversion of the piperazine ring. The entropy is almost negligible. Compound L forms with Cu2+ in aqueous solution complexes [Cu(H(3)L)](3+) and [Cu(2)L](4+) with stability constants log beta(CuH3L) = 33.20(6) and log beta(Cu2L) 16.6(1) in 0.15 mol dm (3) NaClO4 at 298.1 K, respectively. The low stability of the binuclear complex is attributed to the energy loss due to interconversion between the chair and boat conformers of the piperazine moieties. The interaction of Pd2+ with L has been monitored by NMR analysis. The spectral features show formation of strong binuclear complexes with the involvement of all eight nitrogens of the macrocycle.

  In silico identification, design and synthesis of novel piperazine-based antiviral agents targeting the hepatitis C virus helicase

  摘要：

  A structure-based virtual screening of commercial compounds was carried out on the HCV NS3 helicase structure, with the aim to identify novel inhibitors of HCV replication. Among a selection of 13 commercial structures, one compound was found to inhibit the subgenomic HCV replicon in the low micromolar range. Different series of new piperazine-based analogues were designed and synthesised, and among them, several novel structures exhibited antiviral activity in the HCV replicon assay. Some of the new compounds were also found to inhibit HCV NS3 helicase function in vitro, and one directly bound NS3 with a dissociation constant of 570 +/- 270 nM. (C) 2016 Elsevier Masson SAS.

  Ionophores of the bis(crown ether) type, with polyamine linkers, examples of which are known to bind Simultaneously to a cation and its counter anion, have been prepared. One-pot reductive amination, used to couple a benzo-crown aldehyde with aliphatic (both linear and cyclic) and aromatic polyamines. proved to be the most efficient route. A strong inhibition of one synthetic route (amine benzylation) was observed. The competitive interaction between chloride and other anions for binding with the protonated ionophores was examined using Cl-35 NMR spectroscopy. Sandwich complexing of potassium contrasting with single-face complexation of sodium was demonstrated by C-13 NMR Spectroscopy
