Ferrocenylcarbodiimides carrying different redox potentials, 1 and 2, were designed and synthesized as convenient electrochemically active labeling reagents for nucleic acids, which may be used as dually labeling reagents of nucleic acids like Cy3 and Cy5 dyes. These reagents could react with the imino unit of thymine or guanine base on DNA or of uracil base on RNA under a basic buffer condition to yield a labeled product quantitatively in a short period of time. The current responses of the labeled DNAs in square wave voltammetric (SWV) measurement showed a good linear correlation with the amount of the hybridized ones. DNAs labeled with the two different reagents, 1 and 2, could be detected electrochemically at different potentials after hybridization with a DNA probe-immobilized gold electrode.

The novel ferrocenyl naphthalene diimide derivative 1 was synthesized by the condensation reaction between ferroceneacetic acid and terminal amino moieties of two imide substituents of naphthalene diimide. Stopped-flow analysis of the ligand 1 and DNA interaction revealed the following results: (i) the ligand binds to double stranded DNA more strongly than to single stranded DNA; (ii) the ligand does not have a bias against DNA sequence; (iii) the ligand can bind to the DNA·RNA hetero duplex more strongly than to the DNA·DNA duplex. These properties of 1 make it a suitable ligand for analysis of not only DNA but RNA. In fact, a current due to 1 was observed at 269 mV in the differential pulse voltammetric analysis of dA20-immobilized electrode in an electrolyte containing 1. The current increased markedly upon hybridization with polyU, whereas no current increase was obtained for polyA. Since the DNA·RNA hetero duplex is formed between sample RNA and DNA on the electrode, 1 may be used for the electrochemical detection of mRNA expression.

A new type of dimeric cyclic naphthalene diimide derivatives (cNDI-dimers) carrying varied linker length were designed and synthesized to recognize dimeric G-quadruplex structures. All of the cNDI-dimers exhibited a high preference for recognizing G-quadruplex structures, and significantly enhanced the thermal stability of the dimeric G-quadruplex structure over the cNDI monomer by increasing the melting temperature by more than 23 °C, which indicated the strengthened ability of cNDI dimers for stabilizing dimeric G-quadruplex. cNDI dimers also showed a stronger ability to inhibit telomerase activity and stop telomere DNA elongation than cNDI monomer, which showed an improved anticancer potentiality for further therapeutic application.
Cyclic ferrocenylnaphthalene diimides as a probe for electrochemical telomerase assay
Eguchi, Nao,Fujii, Satoshi,Fujimoto, Kazuhisa,Kaneyoshi, Shuma,Sato, Shinobu,Takenaka, Shigeori
, (2022/02/11)
Novel cyclic naphthalene diimides, 8 and 12, containing ferrocene in the cyclic linker were synthesized as G-quartet (G4) specific electrochemical ligands via the reaction of 1,1′-ferrocenedipropanoic acid and the terminal amine moieties of naphthalene diimides with varying linker lengths. The redox potentials of 8 and 12 were ca. 0.2 V (vs. Ag/AgCl), and the background current in an electrolyte was successfully suppressed. Both 8 and 12 bound to TA-core, representing human telomere G4, with K = 4.4 and 38 × 105 M?1, respectively. The current response of 12 to an electrode immobilized with G4 was the highest among the acyclic derivatives, suggesting its potential application in electrochemical telomerase assays.
