AbstractA new organometallic complex coupling photoactive coumarin to a diironhexacarbonyl unit has been successfully prepared and its composition and electronic structure confirmed by elemental and spectroscopic analyses. Emission spectral analysis of the complex reveals photoinduced intramolecular electron transfer from coumarin to the iron-carbonyl moiety. The compound is electrochemically reduced at −1.24 V vs. Fc/Fc+. This reduction is irreversible, attesting to the instability of the complex. Electrochemical evolution of hydrogen in the presence of the complex has been studied and results are discussed.

Background:: One of the approaches to cancer gene therapy relies on tumor transfection with DNA encoding toxins under the control of tumor-specific promoters. Methods:: Here, we used DNA plasmids encoding very potent anti-ERBB2 targeted toxin, driven by the human telomerase promoter or by the ubiquitous CAG promoter (pTERT-ETA and pCAG-ETA) and linear polyethylenimine to target cancer cells. Results:: We showed that the selectivity of cancer cell killing by the pTERT-ETA plasmid is highly dependent upon the method of preparation of DNA-polyethylenimine complexes. After adjustment of complex preparation protocol, cell lines with high activity of telomerase promoter can be selectively killed by transfection with the pTERT-ETA plasmid. We also showed that cells transfected with pTERT-ETA and pCAG-ETA plasmids do not exert any detectable bystander effect in vitro. Conclusion:: Despite this, three intratumoral injections of a plasmid-polyethylenimine complex resulted in substantial growth retardation of a poorly transfectable D2F2/E2 tumor in mice. There were no significant differences in anti-tumor properties between DNA constructs with telomerase or CAG promoters in vivo.
