Binary Phosphorene Redox Behavior in Oxidoreductase Enzymatic Systems

Phosphorene is a two-dimensional material that has many advantageous electronic, electrochemical, and optical properties. However, phosphorene possesses a relatively poor stability in ambient atmosphere. This disadvantage limits its application in several systems and particularly in electrochemical biosensors. Here we evaluate phosphorene as an electrochemical biosensing platform in two different mediator-based oxidoreductase enzymatic systems (glucose oxidase (GOx) and peroxidase from horseradish (HRP)), in which their detection is based on the reduction or oxidation of a mediator. In both cases, the used mediator is the same, ferrocene methanol (FcMeOH). Enhanced electrochemical activity is observed only in the reductive system (HRP-based biosensor) when compared to the oxidative counterpart (GOx-based biosensor). This phenomenon is attributed to the fact that in a reductive environment the phosphorene structure remains intact, while in an oxidative potential, the phosphorene is readily oxidized. In this way, the electroactivity of phosphorene as a sensing platform is strongly dependent on the type of mediator-based enzymatic system. These findings of binary nature of phosphorene are of high importance for construction of phosphorene-sensing platforms and in the development of enzyme logic systems.

Nanoscale polypyrrole sensors for near-field electrochemical measurements

Scanning electrochemical microscopy (SECM) is an electrochemical technique that is used to measure redox activity local to the surface of a sample. The incorporation of shear force (SF) feedback into SECM enables the concurrent acquisition of topographical data. Contemporary SECM measurements require a redox mediator (such as ferrocene methanol (FcMeOH)) for electrochemical measurements; however, redox mediators are detrimental to chemically sensitive materials such as biological cells. In this article, nanoscale polypyrrole membranes doped with dodecylbenzene sulfonate (PPy(DBS)) are deposited at the tip of highly sensitive ultra-microelectrodes (UME) to demonstrate a novel modification of the contemporary SECM?SF imaging technique that operates in the absence of a redox mediator. This technique leverages the redox activity of a PPy(DBS) membrane to locally detect changes in cation concentration. In conjunction with SF imaging, the PPy(DBS) membrane can (i) detect changes in distance from the surface by measuring changes in ion concentration of the diffusion shell, or (ii) detect local cation flux due to cell function when kept at a constant distance from the cell surface through SF-imaging techniques. Therefore, we predict this technique to enable high resolution mapping of surface cation concentrations and impact the field of biological imaging.

Novel anticancer and antibacterial organometallic polymer based on ferrocene as a building block and xanthone bioactive scaffolds: Synthesis, characterization, and biological study

Poly(azine ferrocene-triazole-xanthone amide) (PAFTXA) was successfully synthesized from azine ferrocene bisacetylene (AFcB) and 2,7-(N-2-azidoacetamide) xanthone (NAzX) by using click chemistry protocol. In this paper, innovative AFcB moiety incorporated in this procedure as a monomer. This monomer was prepared in three steps from ferrocene scaffold, and the synthetic processes were discussed in details. Characterization of the synthesized novel intermediate materials, monomer, and the resulting polymer was performed by nuclear magnetic resonance, Fourier transform infrared, thermal gravimetric analysis, differential scanning calorimetry, and ultraviolet-visible spectrophotometer. In addition, the in vitro antibacterial activity of the polymer was appraised against Gram-positive and Gram-negative bacteria by using minimum inhibitory concentration method. Moreover; antitumoral effects of synthesized polymer were evaluated on Hela, MCF-7, and Saos cancer cell lines and compared with normal fibroblast cell line by means of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Promising antiproliferative effects were detected on both epitheloid and mesenchymal cancer cell lines depending on PAFTXA concentration and time. Survey on its characteristic features revealed the proficiencies of our prepared biomaterial such as its high thermal stability as well as valuable antitumoral and antibacterial capabilities that make it an appreciable candidate for further bioapplications.

H2-Acceptorless Dehydrogenative Boration and Transfer Boration of Alkenes Enabled by Zirconium Catalyst

The first example of an efficient and direct dehydrogenative boration of alkenes for vinyl boronate ester synthesis was achieved using a zirconium catalyst. Our methodology avoids using precious transition metals, additional hydrogen acceptors, high temperatures, and long reaction times, which were required to overcome the reducing ability of borane, to give alkyl boronate esters. Detailed mechanistic studies revealed a reversible reaction pathway and further suggested applying the zirconium complex as a ?shuttle catalyst? for transfer boration, which thus sidesteps the use of relatively sensitive borane.

Reactions of Cp2TiMe2 with ferrocene and (n5-Cp)Co(n4-C4Ph4) derived esters and amides: A new route for 1-methylvinyl and methyl ketone derived metal sandwich compounds

Reactions of Cp2TiMe2, with the ester derivatives of organometallic sandwich compounds (n5-RC5H4)Fe(n5-C5H5) and (n5-RC5H4)Co(n4-C4Ph4) (R=ester groups) gave products having R=C(CH2)Me, instead of the expected vinyl ethers indicating conversion of the ester units by Cp2TiMe2 to methyl ketones followed by methylenation. A reaction of Cp2TiMe2 with the diester (n5-RC5H4)Co(n4-C4Ph3R)(R=C(O)OMe) also gave similar results. The study has also been successfully extended to metal sandwich derived amides, thio and seleno esters. By controlling the amount of Cp2TiMe2, the reactions were also stopped at the methyl ketone stage and the methyl ketones were isolated in good yields and characterized. The method provides an easy and direct access to convert organometallic sandwich derived esters and related compounds to 1-methylvinyl derived products.

The substitution chemistry of the tris(3,5-dimethylpyrazolyl)-methanerhodium complex [Rh(CO)2{HC(pz?)3}]+

The complex [Rh(CO)2{HC(pz?)3}][PF6], 1 +[PF6]- {HC(pz?)3 = tris(3,5-dimethylpyrazolyl)methane}, prepared by reacting [{Rh(CO)2(mu-Cl)}2] with HC(pz?)3 in the presence of Tl[PF6], has a distorted square pyramidal structure with a kappa3-HC(pz?)3 ligand. Carbonyl substitution with Lewis bases gives [Rh(CO)L{HC(pz?)3}] [PF6] {L = PPh3, 2+[PF6]-; L = AsPh3, 3+[PF6]-; L = P(o-tolyl)3, 4+[PF6]-}, which have square planar kappa2 structures, confirmed by X-ray crystallography for 2+[PF6]-. The cations 2+ and 3+ have the third pyrazolyl ring orientated pseudo-parallel to the square planar metal whereas 4+ more likely has the third ring orientated exo to that plane. One-electron oxidation of 2+ and 3+ gives the Rh(II) dications [Rh(CO)(PPh3){HC(pz?)3}]2+, 22+, and [Rh(CO)(AsPh3){HC(pz?)3}]2+, 32+, characterised by ESR spectroscopy. Complex 1+[PF6]- reacts with PhC?CPh to give [Rh(CO)(eta2-PhC?CPh)-{HC(pz?)3}] [PF6], 5+[PF6]-, in which the two-electron donor alkyne occupies an equatorial position in a trigonal bipyramidal kappa3 structure. With MeC?CR (R = Me or Et), 1+[PF6]- gives the kappa2 square planar complexes [Rh{eta4-C4Me2R2C(O)}{HC(pz? )3}][PF6] (R = Me, 6+[PF6]-; R = Et, 7+[PF6]-) in which the cyclopentadienone ligands are coordinated via two Rh-monoalkene bonds; the structurally characterised form of 7+ has the two alkyne units linked head-to-head with the CEt termini bound to the ketonic CO group. With HC?CPh or HC?CH, 1+ gives the octahedral, kappa3 rhodium(III) metallacyclopentadienes [Rh(CO)(eta1:eta1?-CHCRCHCR) {HC(pz?)3}][PF6] (R = Ph, 8+[PF6]-; R = H, 9+[PF6]-) with the two alkynes linked head-to-tail in 8+. The reaction of 1+ with HC?CH also gives the cycloheptatrienone (tropone) derivative [Rh{eta4-C6H6C(O)}{HC(pz?)3} ][PF6], 10+[PF6]-, with a kappa3 ligand and the cycloheptatrienone ligand bound to the metal via two Rh-C sigma-bonds and one Rh-monoalkene interaction.

Efficient thiol-yne click chemistry of redox-active ethynylferrocene

The application of ethynylferrocene, FcCCH (1), as a highly efficient electroactive precursor for the thiol-yne click reaction is presented. For this purpose, a wide range of functionalized thiols, namely 2-mercaptoethanol, 1-thioglycerol, 3-mercaptopropionic acid, 4-aminothiophenol, and benzene-1,3-dithiol as well as tetrathiol pentaerythritol tetrakis(3-mercaptopropionate), were investigated. This facile thiol-ethynylferrocene radical reaction has resulted in the quantitative formation and isolation of the newly ferrocenyl-vinyl sulfides FcCH=CHS(CH2)2OH (2Z and 2E), FcCH=CHSCH2CH(OH)CH2OH (3Z and 3E), FcCH=CHS(CH2)2COOH (4Z and 4E), FcC(CH2)S(1,4-C6H4)NH2 (5alpha), FcCH=CHS(1,3-C6H4)SCH=CHFc (6), and [FcCH=CHS(CH2)2COOCH2]4C (7). Thiol-ethynylferrocene reactions have been initiated either by heat, in toluene with AIBN, or by UV light irradiation in THF in the presence of DMPA as photoinitiator. The outcome of the hydrothiolation of ethynylferrocene strongly depends on the thiol structure and on the initiation method employed. A simple mixing of metallocene 1 with the thiol HS(CH2)2OH or HS(CH2)2COOH in a proper ratio, in THF at 20 C, in a initiator-free thiol-yne reaction, causes hydrothiolation of 1 to occur, allowing for the formation of vinyl sulfides 2Z, 2E and 4Z, 4E in good isolated yields. In contrast to the bis-addition typically observed for thiol-yne reactions, no double hydrothiolation to FcCCH has been observed for any of the thiols under any conditions studied. Electrochemical studies showed that tetrametallic compound 7, containing four sulfur-bridged ferrocenyl-vinyl moieties, behaves as a tetrapodal adsorbate molecule, exhibiting excellent chemisorption properties, and spontaneously forms robustly adsorbed 7 films onto Au or Pt electrode surfaces.
