Abstract:
Ferrocene-substituted tetrakis(methyl)resorcin[4]arenes have been investigated by means of DFT calculations employing the gradient-corrected PBEPBE functional. In comparison with ferrocene and simple ansa-ferrocenes containing 2–4 bridging methylene groups, it was found that the tilt angle of the functionalized cyclopentadienyl (Cp) rings strongly influences the electron density distribution of the ferrocenyl moieties. According to NBO analyses, the iron atoms in the cavitands are more positive in comparison to those in ferrocene, whereas they are less positive in ansa-ferrocenes. The partial charges of carbon atoms belonging to Cp rings show some correlation with the tilt angle.

Abstract:
Starting from ethyl 2,4-dioxo-4-ferrocenyl-butanoate (1) a series of new ferrocene derivatives has been prepared. While the reaction with o-phenylene diamine leads to two ferrocene-containing heterocyclic compounds, 4-ferrocenyl-3H-1,5-benzodiazepine-2-carbonic acid ethyl ester (3) and 3-(2-ferrocenyl-2-oxo-ethylidene)-3,4-dihydro-1H-quinoxalin-2-one · H20 (4), reactions with m- and p-phenylene diamine give both the mono- and disubstituted products 5 - 8, respectively. The conversion of 4 by Lawesson’s reagent results in 2-ferrocenvl-thieno[2,3- b]quinoxaline (9). The new compounds have been characterized by their 1H, 13C NMR, and mass spectra. The molecular structures of 4-ferrocenyl-4-oxo-2-phenylamino-but-2-enoic acid ethyl ester 2, and of 4 and 9 have been determined by X-ray crystal structure analysis.

Abstract:
An automated amperometric immunosensors for the quantification of transferrin was fabricated using two monoclonal IgG class anti-rat transferrin antibodies, 15C2H3 and 22A06D2. The former was immobilized on a gold electrode, while the latter was conjugated with the positively charged polymers containing ferrocenyl groups. The quantitative analysis of transferrin was investigated by measuring the electrooxidation current of ferrocene, which is proportional to the transferrin concentration for the equivalently observed sandwich formation. The deposition of electroconductive polymers, polypyrrole (poly-P) and poly⌈ferrocenyl-methyl-3-(pyrrol-l-yl)propyldimethylammonium bromide⌉ (poly-FP), were performed on the surface of antibody-immobilized gold electrode in order to increase the efficiency of the electron transfer between the antibody-cojugated ferrocence and the gold electrode, and to eliminate the nonspecific binding of ferrocene-labeled antibody by a mutual repulsion.

Abstract:
AbstractThe goal of this paper is to study thermal stability of some ferrocenes with acidic functional groups. Some other kinetic characteristics such as critical temperature and the rate constant corresponding to maximal degradation speed have been also evaluated. The type of functional units adjacent to the ferrocenyl unit determines thermal stability of ferrocene compounds. Groups with a powerful withdrawing effect determine a decreasing of the temperatures at which the material starts to lose weight. If a very long alkyl chain is connected to the ferrocene unit, a shielding effect in respect to the other carboxylic groups was observed, with an increase of the thermal stability.

Abstract:
Organometallic sandwich compounds, especially ferrocenes, possess a wide variety of pharmacological activities and therefore are attracting more and more attention from chemists, biologists, biochemists, etc. Excellent reviews concerning biological aspects and design of ferrocene-modified compounds appear regularly in scientific journals. This brief overview highlights recent achievements in the field of bio-organometallic ferrocene chemistry from 2017 to 2022. During this period, new ferrocene-modified analogues of various bio-structures were synthesized, namely, betulin, artemisinin, steroids, and alkaloids. In addition, studies of the biological potential of ferrocenes have been expanded. Since ferrocene is 70 years old this year, a brief historical background is also given. It seemed to me useful to sketch the ‘ferrocene picture’ in broad strokes.

Abstract:
Abstract The potential inhibitory effect of diverse triazolyl-ferrocene steroids on key enzymes of the estrogen biosynthesis was investigated. Test compounds were synthesized via copper-catalyzed cycloaddition of steroidal azides and ferrocenyl-alkynes using our efficient methodology published previously. Inhibition of human aromatase, steroid sulfatase (STS) and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) activities was investigated with in vitro radiosubstrate incubations. Some of the test compounds were found to be potent inhibitors of the STS. A compound bearing ferrocenyl side chain on the C-2 displayed a reversible inhibition, whereas C-16 and C-17 derivatives displayed competitive irreversible binding mechanism toward the enzyme. 17α-Triazolyl-ferrocene derivatives of 17β-estradiol exerted outstanding inhibitory effect and experiments demonstrated a key role of the ferrocenyl moiety in the enhanced binding affinity. Submicromolar IC50 and Ki parameters enroll these compounds to the group of the most effective STS inhibitors published so far. STS inhibitory potential of the steroidal ferrocenes may lead to the development of novel compounds able to suppress in situ biosynthesis of 17β-estradiol in target tissues.

Abstract:
Organometallic compound ferrocene formation was a serendipity and due to its "barrel-shape" which grants 3D geometry of the organometallic compound it has an optimal spatial design for better fitting and connection inside the pockets of the dynamic site in natural targets and receptors. The benzimidazole motif has developed to be a significant privileged heterocyclic platform. Ferrocenyl benzimidazole is a complex organic compound having ferrocene an organometallic compound attached to the 2-position of benzimidazole an aromatic heterocyclic compound. Ferrocene benzimidazole derivatives have attracted lots of attention for the construction of new compounds due to their wide applications. By combining ferrocene and benzimidazole produce a vast range of pharmacological actions. Synthetic method and pharmacological effects of various ferrocenyl benzimidazole derivatives were examined. This review gives the medicinal activities of 2- ferrocenyl benzimidazole derivatives like cytotoxic activity, anti-malarial, anti-microbial, anti-fungal etc. were furnished. Keywords: ferrocene, benzimidazole, cyclopentadiene, 2-ferrocenyl benzimidazole, cytotoxic, anti-malarial.

Abstract:
The first ferrocene nucleic acid (FcNA) was reported by the Tucker group in 2012. Furnished with two nucleobases and two hydroxyl groups, the tetrasubstituted metallocene assumes the position traditionally occupied by the two sugars of a dinucleotide. This thesis describes the successful synthesis of two FcNA monomers; a tetrasubstituted dithyminyl variation and a disubstituted control compound bearing no nucleobases. These monomers were oligomerised, their binding characteristics assessed by thermal melting studies, and compared to other monomers belonging to the group. Through the study of these compounds the Tucker group has demonstrated that FcNA monomers behave similarly to conventional nucleic acids, displaying selective H-bonding and π-stacking interactions within a hybrid duplex. A preliminary methodology for the production of diguaninyl FcNA monomers was also explored. As published in 2014, the corresponding disubstituted systems, in which a hydroxyl and a nucleobase are linked through a sugar-like ferrocene unit, are also being investigated as potential nucleoside analogues. Adding to the groups growing library, a number of related compounds were synthesised in which the hydroxyl linker length, the planar chirality, the substitution pattern of the ferrocene and the nucleobase were varied. The compounds were electrochemically characterised and assessed for their biological activity which revealed interesting structure-activity-relationships involving both the redox potentials and chirality. Following the example of ferroquine and ferrocifen, in which existing pharmaceuticals are modified through the incorporation of ferrocene, the synthesis and preliminary biological activity of novel ferrocenyl β-blockers, in which the metallocene replaces the napthol unit of the prototypical β-blocker propranolol, is reported herein.

Abstract:
This thesis explores the capacity of sterically and electronically unsaturated boranes to bind substrates of biological and environmental interest, and transduce such binding events into a photo-physical and/or electrochemical response, hence reporting the presence of these substrates. Chapter three details the synthesis of a range of novel ferrocenyl boranes featuring either a proximal hydrogen-bond donor or a second Lewis acidic centre. These novel boranes were shown to be competent at binding both cyanide and fluoride anions, with the role played by a proximal hydrogen-bond donor or a second Lewis acidic centre in anion binding investigated by both NMR and crystallographic studies. Chapter four reports the synthesis of novel pyridinyl and related boronic esters, as well as unexpected mixed alkenyl/aryl boranes. The capacity of both types of system to bind fluoride or cyanide anions in solution was investigated by UV-Vis and NMR studies. The photo-physical responses to these anions were also probed, leading to the establishment of both switch-on and switch-off fluorescent responses. Chapter five extends the knowledge derived from selective anion receptor design and combines this with recent developments in the field of frustrated Lewis pairs (FLPs) to activate, bind and report the presence of nitrous oxide (N2O) molecule. Thus, the syntheses of novel, highly Lewis acidic ferrocenyl boranes that incorporate a high degree of steric loading around the boron centre are reported. The electrochemical and photo-physical response of an FLP system to the presence of N2O was investigated leading to the development of a novel N2O reporting system.

Ce travail de thèse est majoritairement consacré au développement d’une voie d’accès originale vers des ferrocènes 1,3-disubstitués basée sur une réaction de migration d’halogène. Dans un premier temps, cette réaction a été optimisée à partir de ferrocène carboxamides. Malgré des rendements modestes, il s’agit des premiers exemples de migration d’halogène contrôlée en série ferrocène. Les réactions parasites identifiées ont permis une meilleure compréhension des facteurs à maîtriser pour le bon déroulement de la réaction. Dans un second temps, nous avons appliqué avec succès la réaction de migration d’halogène à une nouvelle famille de composés aux propriétés uniques, les fluoroferrocènes. Non seulement cette approche a permis d’obtenir des ferrocènes diversement trisubstitués, mais il a également été possible d’accéder à des ferrocènes tétrasubstitués et au premier exemple de ferrocène hétéro- pentasubstituté. Finalement, une étude électrochimique préliminaire a été réalisée sur des ferrocènes originaux. La détermination des potentiels rédox a permis une meilleure compréhension des effets de substituants sur les propriétés électroniques de ces composés et laisse entrevoir le développement d’une méthode de purification originale
This thesis is mainly dedicated to the development of an original approach towards 1,3-disubstituted ferrocenes using the halogen ‘dance’ reaction. This reaction was first optimized on ferrocene carboxamide substrates. Although moderate yields were obtained, these are the first examples of controlled halogen ‘dance’ reaction in the ferrocene series. The noticed side-reactions allowed the key parameters for the success of the reaction to be identified. The halogen ‘dance’ reaction was next successfully developed in the fluoroferrocene series, an underexplored family of molecules with specific properties. Various trisubstituted ferrocenes were obtained and the reaction was also found able to deliver original tetrasubstituted ferrocenes and the very first example of hetero-pentasubstituted ferrocene. Finally, a preliminary electrochemical study was engaged. The determination of redox potentials of some of the original ferrocene derivatives allowed a better understanding of the substituent effects on ferrocene electronic behavior. Furthermore, it lays the ground for the development of an original purification process

Abstract:
Organometallic complexes containing transition metals, such as Ru(II), Os(II), Ir(III), have been moderately and recently used in medicinal chemistry as anticancer, antimalarial, antimicrobial or diagnostic agents. Current trends have led researchers to explore and define new synthetic methods in the quest for the design of new drugs and reduce the inherit associated toxic side-effects by using metal based compounds. Ferrocene based derivatives have been subjected to study for their biological and medicinal applications. Examples include ferrocenophane polyphenol, ferrocenyl quinone methides, ferrocenyl-aminoquinoline-carboxamide and a ferrocene-substituted hydroxytamoxifen, which has been proved as a potential new breast cancer therapeutic. Ferroquine displays antimalarial activity and ferrocifen is a tamoxifen-ferrocene anticancer agent. During the course of our research, we have focused on synthesizing and studying the biological activity of novel organometallic compounds containing the corresponding ferrocene moiety. We aimed to make, at least, 3 different families of compounds, which were cannabinoid receptor (CB1/CB2 receptor agonists), histone deacetylase (HDAC) selective inhibitors and general kinase inhibitors. Firstly, a review covering the state-of-the-art in bioorganometallic chemistry will be presented. Secondly, we started with the synthesis of a small library of compounds containing the following groups: ferrocenylamine, 4-oxo-1, 4-dihydropyridine and dihydroquinoline. We used aminoferrocene as a bioisostere of the adamantylamine group where previous studies of compounds containing the latter group had showed it to effectively interact with the cannabinoid receptors, CB1 and CB2. Some of our compounds displayed good to excellent potency in the nM range against the CB1 and CB2 receptors. Thirdly, we embarked to synthesise HDAC inhibitors knowing their potential as anti-cancer drugs and trying to obtain, wherever possible, enzyme isoform selectivity. One of the well-known HDAC inhibitors is suberoylanilide hydroxamic acid (SAHA). Vorinastat, as it is also known, has received Food and Drug Administration approval for treating patients with cutaneous T-cell lymphoma. The compound developed in our group by replacing ferrocene for the phenyl ring in SAHA, called JAHA, is another example of a highly potent HDAC inhibitor. Our research led to compounds where the hydroxamic acid moiety in JAHA has been replaced by a benzamide group. This transformation has produced a significant effect in delivering a potent HDAC3 selective HDAC inhibitor. This is supported by biological studies and a molecular modelling rationalisation. Next, a series of oxindole based analogues have been synthesized by the Knoevenagel condensation reaction of: 5-(pentafluorosulfanyl)-1,3-dihydro-indol-2-one and 6-(pentafluorosulfanyl)-1,3-dihydro-indol-2-one compound with: ferrocenecarboxaldehyde and pyrrole-2-carboxaldehyde. The compounds thereby synthesised have been studied against a panel of kinases, and kinase inhibitory data will be discussed and presented. In a Future directions section, we will describe the synthesis of FAAH (fatty acid amide hydrolase) inhibitors based on an aminoferrocene backbone.

Abstract:
Chiral recognition, determination of enantiomeric excess and the separation of enantiomers are challenging problems for the chemist. This work has as its aim the design and syntheses of new electrochemical chiral receptors for neutral molecules. All the receptors prepared contain a ferrocene group as electroactive reporting unit. The differences among the receptors mainly relate to the binding site and the chiral group. The first type of receptor, presented in Chapter 2, consists of chiral ferrocene containing boronic acids that have been used to electrochemically sense aromatic and aliphatic chiral and achiral diols. The electrochemical determination of the enantiomeric excess of a mixture of two enantiomers of Binol performed with one of these boronic acids represents a new advance in supramolecular chiral sensing. In Chapter 3 the synthesis of ferrocene-containing chiral macrocycles of different sizes is described. The binding site is a cavity featuring a diamidopyridine moiety, with the chirality introduced through a Binol unit. These receptors showed low interaction with achiral cyclic ureas and chiral carboxylic acids. Chapter 4 describes the study of self-assembled monolayers onto gold surfaces. The monolayers are formed by ferrocene-containing amides of lipoic (thioctic) acid and, for the first time, isolipoic acid. The studies indicate that isolipoic acid could be an attractive anchor group for SAM formation when strong control over the chirality of the monolayer is required.

This thesis is focused on the development of electrochemical DNA sensors, which are decentralized analytical devices for use at the point-of-need for the detection of DNA sequences. These sensors can find widespread application in a number of diverse areas, including clinical diagnostics, disease monitoring, food analysis, forensics, bioterrorism and environmental control. However, electrochemical DNA sensors still have a number of problems that need to be addressed, including a need for the amplification of the target sequence, the need for post-amplification generation of single stranded DNA, target hybridization with a complementary capture probe and finally further reporting steps to detect the hybridized target DNA sequence. In this thesis we focused on the elimination of some of these steps to bring electrochemical DNA sensors closer to the point-of-need. To eliminate the reporting step we used ferrocene labelled dATP (dAEFcTP) to obtain already labelled target amplicons. To eliminate the single stranded generation step we followed two different strategies, the use of tailed primers instead of regular primers, or, alternatively performing DNA amplification directly on the electrode surface. The incorporation of dAEFcTP has been demonstrated in primer extension and amplification experiments. dAEFcTP and tailed primers have been used to develop a singleplex electrochemical sensor to detect K. armiger in seawater samples, and a duplex electrochemical sensor to detect B. anthracis in real samples. The effect of the dAEFcTP:dATP ratio on DNA amplification yield, ferrocene peak intensity and limit of detection has been studied, as well as the effect of the electrolyte solution on the ferrocene peak intensity. Finally, the use of dAEFcTP in combination with isothermal recombinase polymerase amplification was explored.

Abstract:
A cristalografia por difração de raios X (DRX) é uma ciência eminentemente interdisciplinar, cujo desenvolvimento tem possibilitado o avanço de várias outras áreas científicas. A determinação das estruturas tridimensionais de substâncias, sejam elas naturais ou sintéticas, tem sido fundamental para o estudo e compreensão das relações entre propriedades físicas, químicas e terapêuticas, e a estrutura a nível atômico. Neste trabalho serão apresentados alguns aspectos teóricos sobre complexos ferrocenos e a teoria envolvida na determinação de estruturas cristalinas e moleculares por DRX, bem como a resolução e caracterização de dois complexos ferrocenos. Os resultados obtidos foram comparados com estruturas similares encontradas no Cambridge Structural Database. Nos compostos estudados no presente trabalho, 1,1\'- bis(difenilfosfina)ferroceno e oCHCl3, o Fe apresentou-se complexado a dois anéis de ciclopentadienila, em conformação estrela, os quais estão dispostos de forma equidistante do átomo de Fe, não apresentando distorções significativas. Devido à alta toxicidade da cis-platina no tratamento de neoplasias, muitos grupos de pesquisa têm dedicado seus esforços a encontrar fármacos análogos compatíveis, sendo os derivados de paládio muito visados por terem propriedades eletrônicas e estruturais semelhantes. Sabe-se que a geometria em torno do átomo de platina, na cis-Pt, é quadrado planar, como no presente caso, o que torna o composto oCHCl3 passível de ser estudado quanto à sua possível atividade. Uma das grandes incógnitas dentro da área de farmacologia é saber exatamente quais são os produtos oriundos da degradação de um determinado fármaco e através da determinação por DRX das estruturas cristalinas e moleculares dos dois compostos estudados, concluiu-se que os mesmos são oriundos da degradação do composto [Pd2(C2, N-(dmpa) 2 (μ-dppf)Cl2], uma vez que os compostos estudados tiveram suas estruturas determinadas a partir de um tubo contendo o composto inicial. Portanto, o presente trabalho possui uma considerável importância no estudo deste fármaco o qual pode ser usado no combate ao câncer.
X-ray diffraction is a highly interdisciplinary science, whose development has enabled the advancement of several other scientific areas. The determination of three-dimensional structures of substances, whether natural or synthetic, have been fundamental to the study and understanding of the relationships between physical, chemical, therapeutic and structure at the atomic level. This work will present some theoretical aspects of ferrocene complexes and the theory involved in determining of molecular and crystal structures by XRD, as well as resolution and characterization of two ferrocene complexes. The results were compared with similar structures found in the Cambridge Structural Database. At the compounds studied in the present work, 1,1\'-bis(diphenylphosphine)ferrocene e {(Dichloride)[bis (diphenylphosphine)-ferrocene]Palladium(II)}oCHCl3, the Fe complexes with two cyclopentadyenil rings, at star conformation, which are disposed equidistant from Fe atom, without significant distortions. Due to the elevated toxicity of cis-platine at neoplasms, many research groups have been dedicated efforts to found compatible analog drugs, which the palladium derivatives are the most researched, because of their electronic and structural properties. It has been known that the geometry around the Pt is square planar, as like as the present case, which makes the {(Dichloride)[bis (diphenylphosphine)-ferrocene] Palladium(II)}oCHCl3, possible to be study at his possibly activity. One of the great unknowns in the area of pharmacology is to know exactly which are the products of degradation of a certain drug and determining by XRD the crystal and molecular structures of both studied compounds, concluded that they are derived from the degradation of the compound [Pd2(C2, N-(dmpa) 2 (μ-dppf)Cl2], since such compounds has their structures determined from a tube containing the [Pd2(C2, N-(dmpa) 2 (μ-dppf)Cl2]. So, the present work has considerable importance in the study of this drug which can be used against cancer.

Abstract:
Ferrocene derivatives are known as antioxidants, antiparasitic, antitumor, antiviral, antibacterial and antifungal agents. In addition to applications in medicinal chemistry and drug design, ferrocene derivatives are of exceptional importance in synthetic organic chemistry, especially in catalytic asymmetric transformations. They are also used in electrochemistry and polymer chemistry, as additives in fuels, as chemosensors in agrochemistry and biosensors of glucose and active components in molecular electronics. To design new antioxidant agents, five ferrocenyl chalcones were synthesized, and fully characterized by melting points, FT-IR, 1H and 13C NMR spectroscopic methods. The synthesized chalcones differ in the nature and the position of the substituent attached to the phenyl group in position 1 of the linear unsaturated carbonyl system. The potential antioxidant activity of the synthesized compounds was evaluated using the ABTS (2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) method and IC50 values of the most effective compounds were further determined.

Full text
Abstract:
In this technical report (TR), a robust, readily synthesized molecule with a ferrocene core appended with one or two boronic acid moieties was designed, synthesized, and used toward F- (free fluoride) detection. Through Lewis acid-base interactions, the boronic acid derivatives are capable of binding with F- in an aqueous solution via ligand exchange reaction and is specific to fluoride ion. Fluoride binding to ferrocene causes significant changes in fluorescence or electrochemical responses that can be monitored with field-portable instrumentation at concentrations below the WHO recommended limit. The F- binding interaction was further monitored via proton nuclear magnetic resonance spectroscopy (1H-NMR). In addition, fluorescent spectroscopy of the boronic acid moiety and electrochemical monitoring of the ferrocene moiety will allow detection and estimation of F- concentration precisely in a solution matrix. The current work shows lower detection limit (LOD) of ~15 μM (285 μg/L) which is below the WHO standards. Preliminary computational calculations showed the boronic acid moieties attached to the ferrocene core interacted with the fluoride ion. Also, the ionization diagrams indicate the amides and the boronic acid groups can be ionized forming strong ionic interactions with fluoride ions in addition to hydrogen bonding interactions.
