Biodegradable electroactive polymers for electrochemically-triggered drug delivery

We report biodegradable electroactive polymer (EAP)-based materials and their application as drug delivery devices. Copolymers composed of oligoaniline-based electroactive blocks linked to either polyethylene glycol or polycaprolactone blocks via ester bonds were synthesized in three steps from commercially available starting materials and isolated without the need for column chromatography. The physicochemical and electrochemical properties of the polymers were characterized with a variety of techniques. The ability of the polymers to deliver the anti-inflammatory drug dexamethasone phosphate on the application of electrochemical stimuli was studied spectroscopically. Films of the polymers were shown to be degradable and cell adhesive in vitro. Such EAP-based materials have prospects for integration in implantable fully biodegradable/bioerodible EAP-based drug delivery devices that are capable of controlling the chronopharmacology of drugs for future clinical application.

Some insights into the gold-catalysed A3-coupling reaction

A series of cyclometallated and functionalised NHC gold(I) and gold(III) complexes, many of which feature chiral ligands, and their application to A3-coupling reactions is presented. Gold(III) complexes were found to be particularly effective catalysts for the coupling in a range of solvents, however no asymmetric induction was obtained when using chiral gold complexes and the rate of product formation was found to be similar even when using different ligand systems. In-situ NMR analysis of these reactions indicates that decomposition of the catalyst occurs during the course of the reaction while TEM studies revealed the presence of gold nanoparticles in crude reaction mixtures. Taken together these data suggest that the gold nanoparticles, rather than the intact gold complexes, could be the catalytically active species, and if so this may have significant implications for other gold-catalysed systems.

H2Dfoh appears to act as a bidentate ligand, coordinating to two metal atoms through the azomethine nitrogen and enolic oxygen atoms. OAc- coordinates to the metals as a symmetric bidentate ligand.

Selective borane reduction of phosphinoferrocene carbaldehydes to phosphinoalcohol-borane adducts. the coordination behaviour of 1-(diphenylphosphino)- 1?-(methoxymethyl)ferrocene, a new ferrocene O,P-hybrid donor prepared from such an adduct

The reduction of ferrocene phosphino-aldehydes, R2PfcCHO (R = Ph, 2; Cy, 3; fc = ferrocene-1,1?-diyl, Cy = cyclohexyl) and (S p)-[Fe(eta5-C5H3-1-CHO-2-PPh 2)(eta5-C5H5)] ((S p)-4), with BH3¡¤THF or BH3¡¤ SMe2 in THF at 0 C selectively afforded the corresponding phosphinoalcohol-borane adducts, R2PfcCH2OH¡¤BH 3 (R = Ph, 5; Cy, 6) and (Sp)-[Fe(eta5-C 5H3-1-CH2OH-2-PPh2) (eta5-C5H5)]¡¤BH3 ((S p)-7), in quantitative yields. In contrast, the reactions performed at elevated temperatures favoured the formation of methyl derivatives (e.g., Ph2PfcCH3¡¤BH3 (8)) resulting from overreduction (deoxygenation). The crystal structures of 3, 5, (S p)-7, 8 and Cy2PfcBr (9) have been determined by single-crystal X-ray diffraction analysis. The crystal assemblies of adducts 5 and (Sp)-7 are built up by means of C-H…O contacts, O-H…HB dihydrogen bonds and other soft interactions but, surprisingly, not via the conventional O-H…O hydrogen bonds. Adduct 5 was smoothly deprotected to give the corresponding free phosphine, Ph2PfcCH 2OH (1), and was further used for the preparation of a hybrid phosphinoether ligand, Ph2PfcCH2OMe (11). The latter compound was studied as a donor for Group 8-10 metal ions and for Cu(i), whereupon the following complexes were isolated and structurally characterised: [(eta6-p-cymene)RuCl2(11-kappaP)] (12*), [(eta6-p-cymene)RuCl(11-kappaP)(MeCN)][SbF6] (13*), [RhCl(cod)(11-kappaP)] (cod = eta2: eta2-cycloocta-1,5-diene; 14), trans-[PdCl2(11-kappaP) 2] (trans-15*), [PdCl(mu-Cl)(11-kappaP)]2 (16*), cis- and trans-[PtCl2(11-kappaP)2] (cis-17 and trans-17*), and [Cu(CF3SO3-kappaO)(11- kappaP)(H2O)] (18) (the asterisk indicates that the crystal structure was determined). In all these compounds, ligand 11 behaves as a P-monodentate donor while its ether group remains uncoordinated. This probably reflects structural flexibility of 11 resulting from the presence of the methylene linker and also distinguishes 11 from its known, non-spaced analogue Ph2PfcOMe.

Study of the protection performance of self-assembled monolayers on copper with the scanning electrochemical microscope

The protection performance of self-assembled monolayers (SAMs) formed by 2-(Pyridin-2-yliminomethyl)-phenol (HL) on the surface of copper has been studied in situ with the scanning electrochemical microscope (SECM). The pitting dynamic processes were observed in sodium chloride solution without the presence of SAMs, but they tended to be inhibited by SAMs if the assembly time was long enough. During the scanning process, the self-assembled method decreases the interaction between the HL molecules and the SECM tip greatly.

Micro ring-disk electrode probes for scanning electrochemical microscopy

The construction and characterisation of ring-disk (RD) microelectrodes suitable for use in scanning electrochemical microscopy (SECM) is reported. Such RD electrodes are proposed as probes for novel generator-collector SECM experiments. In this case, the interaction of both the reactants and products with the substrate under investigation can be followed simultaneously from a single approach curve to the substrate. Examples of such approach curves to conducting and insulating substrates are given to demonstrate the potential of this new mode of SECM operation.

Synthesis and characterization of ferrocenylalcohol derivatives of hexachlorocyclotriphosphazene. X-ray crystal structure of N3P3Cl5OCH2CH2C5H4FeCp

The preparation of 1-ferrocenyl-2-propanol (5) from lithioferrocene and propylene oxide is described. The reaction of lithium diisopropylamide with 2-ferrocenylethanol (3) or 1-ferrocenyl-2-propanol (5), followed by the addition to hexachlorocyclotriphosphazane (1) provides N3P3Cl6-n (OCHRCH2C5H4FeCp)n [R=H, n=1 (3) or 2 (4); R=CH3, n=1 (6)]. The corresponding reactions with ferrocenylmethanol lead to degradation products via a phosphazene-phosphazene rearrangement. The substitution pattern observed for N3P3C14(OCH2CH2C5H4FeCp)2 (4) suggests that the reaction follows a predominantly cis-non-geminal pathway. The substituted phosphazene derivatives were characterized by standard means including 31P-NMR, mass spectrometry, elemental analysis and cyclic voltammetry. An X-ray crystal structure of N3P3C15(OCH2CH2C5H4FeCp) (3) was obtained.
