A convenient, sensitive, and label-free method to determine the DNA methylation status of CpG sites of plasmid and human colon cancer cell has been developed. The system relies on highly selective single base extension reaction and significant optical amplification of cationic conjugated polyelectrolytes (CCP-1). The higher fluorescence resonance energy(More)
The reaction mechanisms of the Pd(ii)-catalyzed oxidative carbocyclization-alkoxycarbonylation of bisallenes to construct seven-membered carbocycles have been theoretically investigated with the aid of density functional theory (DFT) calculations. Our calculation results account for the experimental fact that the product should be the seven-membered(More)
The protonated adrenaline (PAd(+)) forms supramolecular complexes with crown ethers by extensive hydrogen bond and ion-dipole interactions. Recent experiments and calculations have demonstrated the molecular recognition of PAd(+) through the supramolecular complexes formed between 12-crown-4 (12C4) and 15-crown-5 (15C5). In the present article, 18-crown-6(More)
The coupling reaction mechanisms of the Rh(iii)-catalyzed redox-neutral C7-selective aryl C-H functionalization of indolines with alkynes and alkenes have been theoretically investigated with the aid of the density functional theory (DFT) calculations. Our calculation results indicate that the active catalyst in this system is the cationic species(More)
The electron transfer properties were investigated for supramolecular complexes of formamide (FA) with adrenaline (Ad) at graphite electrode and paraffine soaked graphite electrode using cyclic voltammetry (CV). The experimental results show that FA affected the electron transfer properties of Ad. The formed supramolecular complexes by hydrogen bond(More)
Protonated adrenaline (PAd) can be oxidized to protonated adrenaline quinone (PAdquinone) through a one-step, two-electron redox reaction. The electron-transfer property of PAd and its supramolecular complex with glycine has been investigated by cyclic voltammetry (CV) experiment and theoretical calculations. From CV curves, the conditional formal redox(More)
