Structure-activity relationship of trifluoromethyl-containing metallocenes: Electrochemistry, lipophilicity, cytotoxicity, and ROS production

We report the synthesis of trifluoromethylated metallocenes (M=Fe, Ru) and related metal-free compounds for comparison of their biological properties with the aim to establish structure-activity relationships toward the anti-proliferative activity of this compound class. All new compounds were comprehensively characterized by NMR spectroscopy (1H, 13C, 19F), mass spectrometry, IR spectroscopy, and elemental analysis. A single-crystal X-ray structure was obtained on the Ru derivative, 1-(1-hydroxy-1-hexafluoromethylethyl)ruthenocene (3). The cytotoxicity of all compounds was tested on MCF-7, HT-29, and PT-45 cells, and IC50 values as low as 12 muM were observed. Both the metallocene moiety and the hydroxy function are crucial for cytotoxicity. In addition, the activity decreased sharply even if only one trifluoromethyl group was replaced with a methyl group. Electrochemical investigations by cyclic voltammetry revealed that all CF3-containing compounds are harder to oxidize than the unsubstituted metallocenes. Moreover, log-P determination by RP-HPLC showed the fluorinated derivatives to have higher lipophilicity, with log-P values up to 4.6. At the same time, the generation of reactive oxygen species (ROS) in Jurkat cells by these compounds was investigated by flow cytometry. Strong ROS production was shown exclusively for the bis-CF3 derivative 1-(1-hydroxy-1-hexafluoromethylethyl)ferrocene (1) after 6 and 24 h. Also on the Jurkat cell line, only compound 1 strongly induces necrosis after 24 and 48 h, as shown by annexin V/propidium iodide staining. No induction of apoptosis was observed. We propose that compound 1 is more efficiently incorporated into cancer cells relative to all other derivatives, causing significant induction of oxidative stress within the cell, which ultimately leads to cell death. Fluorinated oxidizers: A series of trifluoromethyl-containing metallocenes was synthesized to carry out SAR determinations. All compounds were tested for cytotoxic effects against a range of cancer cell lines, ROS production, electrochemical behavior, lipophilicity, and their capacity to induce apoptosis/ necrosis. Cytotoxicity assays underscore the crucial role of the metallocene moiety, CF3 groups, and the OH function for anti-proliferative effects.

Synthesis, structure and redox potentials of biologically active ferrocenylalkyl azoles

The syntheses, structures, electrochemical properties of the series of ferrocenylalkyl azoles, FcAlkAz, as well as the antitumor activity of ferrocenylmethyl benzimidazole (8) have been studied. Above mentioned compounds were investigated by the method of cyclic voltametry. All of them exhibited a reversible one-electron oxidation-reduction wave owing to the ferrocene-ferrocenium redox couple with a positive shift (0.50-0.65 V) compared with that of ferrocene (0.42 V). The X-ray determination of molecular structures of 1-(ferrocenylmethyl)imidazole (4), 1-(ferrocenylbenzyl)imidazole (7) and 1-(ferrocenylmethyl)bezimidazole (8) was carried out. Compound 4 with imidazolyl substituent was found to be present in N-protonated form. Antitumor activity of 1-(ferrocenylmethyl)benzimidazole (8) against some solid tumor models such as adenocarcinoma 755 (Ca755), melanoma B16 (B16) and Lewis lung carcinoma was studied. The antitumor activity of compound 8 was compared with cisplatin effectiveness against some experimental tumor systems.

The influence of structure in the reaction of electrochemically generated ferrocenium derivatives with reduced glucose oxidase

The synthesis and characterisation of a series of ferrocenylaminoalcohols is reported. 1,2-Aminoalcohol compounds were prepared from the respective ferrocene aldehydes via reaction with trimethylsilylcyanide followed by reduction with LiAlH4. This series includes the ferrocene derivative 1,1?-dimethyl-3-(2-amino-1-hydroxyethyl)ferrocene 1, which is used as a redox mediator to glucose oxidase in a commercial biosensor for determining blood glucose levels in diabetics. The aminoalcohol derivatives are included in a structure-activity study involving the electrochemical determination of the mediation rates of a range of systematically substituted ferrocenes with glucose oxidase. These mediation rates are correlated with structure.

Electrochemical investigation on the polycondensation kinetics of silicon alkoxides by functionalization of the silica network by redox species

The sol-gel polycondensation of tetramethoxysilane has been followed for the first time by functionalization of the oligomeric silane species with a redox active ferrocene. Recording the decrease of the average diffusion coefficient of the mobile species brings information on the sol or gel state, as well as an easy insight of the polycondensation kinetics.

Experimental charge density analysis of symmetrically substituted ferrocene derivatives

Experimental charge density analysis of three symmetrically substituted ferrocene derivatives: 1,?- dimethyl ferrocene (1), decamethyl ferrocene (2), and 1,?-diacetyl ferrocene (3) was conducted. The electron donating or accepting propensities of the ferrocene substituents were evaluated. The metal ligand interactions in all analyzed compounds were found to be similar in terms of charge density concentrations at Bond Critical Points (BCPs), laplacian values, and deformation density features. The monopole population of iron in all cases tend to be slightly negative, suggesting charge donation from Cp ligands. d orbital populations in all cases adopt values in agreement with theoretical calculations and ligand field theory. The charge distribution over analyzed molecules does not correlate with the formal oxidation potential in the analyzed compounds, as compound 2 in the currently studied structure takes the place suitable for an unsubstituted ferrocene. The non-intuitive low energy of the eclipsed conformation of 1 compound finds some explanation in the existence of a bond critical point between atoms of the two methyl groups in the structure. An asymmetry of the atomic surroundings of the two oxygen atoms in the 3 structure, reflected by the differences in charge rho(rBCP) and ?2rho(rBCP) values and the shape of deformation density in the regions of oxygen lone electron pairs, is described.

Synthesis and characterization of (CH=CH)3-bridged heterobimetallic ferrocene-ruthenium complexes

The complex Fc(CH=CH)2C?C-TMS (Fc = ferrocenyl) was obtained from Wittig olefination of FcCH2PPh3Br with TMS-C?CCH=CHCHO in THF. The conjugated monometallic diene can be desilylated to give Fc(CH=CH)2C?CH, which reacted with RuHCl(CO)(PPh3)3 to produce Fc(CH=CH)3RuCl(CO) (PPh3)2. Treatment of the latter complex with PMe 3, 4-phenylpyridine (PhPy), 2,6-(Ph2PCH2) 2C5H3N (PMP), and KTp (Tp = hydridotris(pyrazolyl)borate) gave Fc(CH=CH)3RuCl(CO)(PMe 3)3, Fc(CH=CH)3RuCl(CO)(PhPy)(PPh 3)2, Fc(CH= CH)3RuCl(CO)(PMP), and Fc(CH=CH)3RuTp(CO)(PPh3), respectively. The structures of Fc(CH=CH)2C?CH and Fc(CH=CH)3RuCl(CO)(PMe 3)3 have been confirmed by X-ray diffraction.

Inclusion complexes of ferrocenes and beta-cyclodextrins. Critical appraisal of the electrochemical evaluation of formation constants

We report the results of a systematic electrochemical study of the host-guest supramolecular adducts between ferrocene (Fc), ferrocenium cation (Fc+), and other mono- and disubstituted ferrocene derivatives with different beta-cyclodextrins (CD) in mixed organic-aqueous media. The influence on the formation constants (Kf) of the organic cosolvent, the different substituents on Fc, and the type of CDs are evaluated. NMR and conductometry responses of ferrocenium cation solutions in the presence of CD confirm the weak propensity of Fc+ to enter into the cyclodextrin cavity. The Kf value generally decreases as the steric bulk and the rigidity of Fc substituents increases, consistent with an inclusion model in which the Fc fits into the CD cavity in an axial mode while the substituent protrudes out. Interestingly, the addition of sulfated beta-CD shifts the redox Fc/Fc+ couple toward cathodic values, indicating that the oxidized, cationic form Fc+ is more strongly bound to the sulfated cyclodextrin than neutral Fc, probably by means of electrostatic interaction with the external -SO3- functionalities.
