  Charge transfer in covalently-linked porphyrin-donor complexes from picosecond transient absorption spectroscopy

  摘要：

  Octaalkyl free base porphyrins have been synthesized with covalently attached electron donors at a single meso position. Singlet-state lifetimes were determined from fluorescence quenching in three solvents and were found to be less-than-or-equal-to 1.5 ps for the N,N,N,N'-tetramethyl-1,4-phenylenediamine (TMPD) appended complex, 1.3 ns for the phenyl-TMPD-appended complex, and greater-than-or-equal-to 5 ns for the phertyl-appended, N,N-dimethylaniline (DMA) appended, and DMA-TMPD-appended porphyrin complexes in o-difluorobenzene. Single photon counting measurements and fluorescence quantum yield quenching studies of the phenyl-appended control and phenyl-TMPD charge-transfer complex gave 14 +/- 3 and 2 +/- 0.3 ns excited-state lifetimes, respectively. Fluorescence quantum yields of the TMPD and phenyl-TMPD porphyrins were higher in solvents with lower dielectric constants. Picosecond absorption spectroscopy was performed on molecules exhibiting fluorescence quenching to characterize the charge-transfer state and to determine the recombination kinetics. Conclusive evidence of charge transfer was obtained by observing the donor cation absorption at 606 nm for the TMPD and phenyl-TMPD porphyrins. Picosecond absorption changes in the 380-500-nm region are complete within 50 ps for the TMPD-appended free base porphyrin and 11.5 ns for the phenyl-TMPD-appended free base porphyrin. First-order kinetic analysis indicates that the charge recombination rates are 26 +/- 3 ps and 3.5 +/- 0.4 ns for the TMPD-appended and phenyl-TMPD-appended complexes, respectively. These data yield beta = 0.8-1.1 angstrom-1 for the exponent in the distance dependence of the electron-transfer rate, exp{-beta(r-r0)}. Inasmuch as similar beta values have been determined for electron transfer through saturated bonds, it can be concluded that the pi system of the meso substituents is ineffective in mediating electron transfer, as expected from the near orthogonality of the porphyrin and substituent rings. This is the first systematic study of electron transfer in porphyrin-donor complexes.

  An enzyme called urease assists highly pathogenic bacteria in colonizing and maintaining themselves. Accordingly, inhibiting urease enzymes has been shown to be a promising strategy for preventing ureolytic bacterial infections.

  This study aimed to synthesize and evaluate the bioactivity of a series of semicarbazone derivatives.

  A series of piperazine-based semicarbazone derivatives 5a-o were synthesized and isolated, and their structures were elucidated by 1H-NMR and 13C-NMR spectroscopic techniques besides MS and elemental analysis. The urease inhibition activity of these compounds was evaluated using the standard urease enzyme inhibition kit. An MTT assay was performed on two different cell lines (NIH-3T3 and MCF-7) to investigate the cytotoxicity profile.

  All semicarbazone 5a-o exhibited higher urease inhibition activity (3.95–6.62 μM) than the reference standards thiourea and hydroxyurea (IC50: 22 and 100 μM, respectively). Derivatives 5m and 5o exhibited the best activity with the IC50 values of 3.95 and 4.05 μM, respectively. Investigating the cytotoxicity profile of the target compound showed that all compounds 5a-o have IC50 values higher than 50 μM for both tested cell lines.

  The results showed that semicarbazone derivatives could be highly effective as urease inhibitors.
