Potentiometric studies of the interaction of amine-bridged dinuclear palladium(II) complex with nitrogen bases

Complexes formed by interaction of trans-diamminepalladium(II) chloride (Pd-II) with 1,6-hexanediamine (HDA) and nitrogen bases (B) (imidazole derivatives or methylamine) are investigated at 25 degrees C and 0.1 mol L-1 NaNO3 ionic strength using potentiometric measurements. The stability constants of all possible mononuclear and binuclear complexes were determined. The concentration distribution diagram of the binuclear Pd-II-HDA-Im derivative reveals the complexes predominating in the physiological pH range; the reaction of the binuclear Pd-II-HDA-Pd II with imidazole derivatives is quite feasible.

Theoretical studies on the reactivity of mono-substituted imidazole ligands

The global and local quantum chemical reactivity descriptors of a series of imidazole derivatives substituted at 2, 4, and 5 positions with different groups including electron-donating and electron-withdrawing substituents have been calculated using the B3LYP/6-311++G(d,p) and MP2/6-311++G(d,p) methods. The substituents have been selected to cover a wide range of electronic effects. Considering the calculated Fukui functions, both imidazole derivatives and their anions are found to be suitable nucleophilic sites in the gas phase. For the most substituents it was observed that the calculated Fukui function values at the N-site are small in case of electron-releasing substituents indicating a preferred N-site for hard reaction. In contrast, large values in case of electron-attracting groups indicate a preferred N-site for soft reaction. These two local descriptors predicted the reactivity of the electron-rich imidazole sequence to be 2-substituted imidazoles > 5-substituted imidazoles > 4-substituted imidazole where reactivity toward electrophilic attack at a pyridine nitrogen atom is enhanced by electron donor substituents elsewhere in the molecule, due to resonance effect.

A Series of Imidazole Derivatives: Synthesis, Two-Photon Absorption, and Application for Bioimaging

A new series of D-pi-A type imidazole derivatives have been synthesized and characterized. Two corresponding imidazolium salts (iodine and hexafluorophosphate) were prepared from the imidazole compound. Their electron-withdrawing ability can be largely tunable by salt formation reaction or ion exchange. UV-vis absorption and single-photon fluorescence spectra have been systematically investigated in different solvents. The two-photon cross sections (delta(2PA)) of the imidazole derivatives are measured by two-photon excited fluorescence (2PEF) method. Compared with those of T-1 (107 GM) and T-3 (96GM), T-2 (imidazolium iodine salt) has a large two-photon absorption (2PA) cross section value of 276 GM. Furthermore, the cytotoxicity and applications in bioimaging for the imidazole derivatives were carried out. The results showed that T-1 can be used as a lysosomal tracker with high stability and water solubility within pHs of 4-6, while T-2 and T-3 can be used as probes for cell cytoplasm.

Anti-Candida Activity of 4-Morpholino-5-Nitro- and 4,5-Dinitro-Imidazole Derivatives

The activities of some 4-morpholino-5-nitro- and 4,5-dinitro-imidazole derivatives with respect to several Candida species were evaluated. It is established that 4,5-dinitroimidazole derivatives constitute an important group of compounds possessing antifungal activity against Candida species. Some analogs showed moderate antifungal ability in vitro, especially in relation well-known antifungals such as flucytosine (5FC). The best results of antifungal action were obtained for 1-(3-bromo-2-hydroxypropyl)-2-methyl-4,5-dinitroimidazole (3c), 1-(3-bromo-2-oxopropyl)-2-methyl-4,5-dinitroimidazole (4c) and 2-methyl-1-phenacyl-4,5-dinitroimidazole (2b). The latter compound proved to be effective against Candida sake S-1 (in contrast to inactive 5FC).
