Structure-activity relationship of 3-substituted N-(pyridinylacetyl)-4- (8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene)- piperidine inhibitors of farnesyl-protein transferase: Design and synthesis of in vivo active antitumor compounds

Novel tricyclic Ras farnesyl-protein transferase (FPT) inhibitors are described. A comprehensive structure-activity relationship (SAR) study of compounds arising from substitution at the 3-position of the tricyclic pyridine ring system has been explored. In the case of halogens, the chloro, bromo, and lode analogues 19, 22, and 28 were found to be equipotent. However, the fluoro analogue 17 was an order of magnitude less active. Whereas a small alkyl substituent such as a methyl group resulted in a very potent FPT inhibitor (SCH 56580), introduction of bulky substituents such as tert-butyl compound 33, or a phenyl group, compound 29, resulted in inactive FPT inhibitors. Polar groups at the 3-position such as amine 5, alkylamino 6, and hydroxyl 12 were less active. Whereas compound SCH 44342 did not show appreciable in vive antitumor activity, the 3-bromo-substituted pyridyl N- oxide amide analogue 38 was a potent FPT inhibitor that reduced tumor growth by 81% when administered q.i.d. at 50 mpk and 52% at 10 mpk. These compounds are nonpeptidic and do not contain sulfhydryl groups. They selectively inhibit FPT and not geranylgeranyl-protein transferase-1 (GGPT-1). They also inhibit H-Ras processing in COS monkey kidney cells and soft agar growth of Ras-transformed cells.

Poly[[(pyridazine-kappaN)copper(I)]-mu3-thiocyanato- kappa3 N:S:S]

The crystal structure of the [Cu(NCS)-(C4H4N 2)]n was investigated. Each Cu atom was coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron in the above compound. The compound was prepared by the reaction of CuSCN and pyridazine in acetonitrile in a teflon-lined steel autoclave at 373 K. It was observed that only one N atom of the pyridazine ligand was involved in Cu coordination. It was shown that the Cu atoms were connected via the thiocyanate anions, forming layers parallel to the ab plane.

Antifouling technology – Past, present and future steps towards efficient and environmentally friendly antifouling coatings

The imminent ban of environmentally harmful tributyltin (TBT)-based paint products has been the cause of a major change in the antifouling paint industry. In the past decade, several tin-free products have reached the commercial market, and claimed their effectiveness as regards the prevention of marine biofouling on ships in an environmentally friendly manner. The main objective of this review is to describe these products in as much detail as possible based on the knowledge available in the open literature. This knowledge has been supplemented by means of performance data provided, upon request, by some of the paint-producing companies. An exhaustive review of the historical development of antifouling systems and a detailed characterisation of sea water are also included. The need for studies on the behaviour of chemically active paints under different sea water conditions is emphasised. In addition, the most common booster biocides used to replace TBT-containing compounds are listed and described. It must be stressed that there is still a lack of knowledge of their potential environmental side effects. The current interest in providing innovative antifouling technologies based on an improved understanding of the biological principles of the biofouling process is also considered in this review. From the analysis of the factors affecting the biofouling process, the interference with the settlement and attachment mechanisms is the most promising environmentally benign option. This can be accomplished in two main ways: imitation of the natural antifouling processes and modification of the characteristics of the substrate. The former mostly focuses on the study of the large amount of secondary metabolites secreted by many different marine organisms to control the fouling on their surfaces. The many obstacles that need to be overcome for the success of this research are analysed. The potential development of broad-spectrum efficient coatings based on natural antifoulants is far from commercialisation. However, exploitation of a weakening of biofouling adhesion by means of the non-stick and fouling-release concepts is at a rather advanced stage of development. The main advantages and drawbacks of these systems are presented along with a brief introduction to their scientific basis. Finally, other alternatives, which may eventually give rise to an efficient and environmentally benign antifouling system, are outlined.

Halogen Bonds Involved in Copper(I) Complexes: A Study Based on the Electronic Charge Density

This communication describes the crystal structures of CuI complexes and their topological analysis with an emphasis on the Laplacian of the electron density to investigate the characteristics of halogen bonding. To gain insight into the halogen bonds (XBs), we survey wavefunction and DFT methods. The different XBs, that is, Cl···Cl?, I···I?, Br···N3?, and I···SCN?, in the crystal packing of these compounds are categorized as a combination of a region of charge depletion and a region of charge concentration in the valence-shell charge concentration or hole?lump interactions. The full quantum potential based lump?hole concept is more useful than the sigma-hole concept, in which the electrostatic portion of the potential is merely considered. Such a view of halogen bonding can rationalize the geometry around the XBs. The noncovalent interaction reduced density gradient (NCI-RDG) approach was applied to the real-space visualization and quantitative investigation of the XBs as well.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 1448-87-9!, Reference of 1111-67-7

Structure, binding energy and optoelectrical properties of p-type CuI thin films: The effects of thickness

Ultra-high transparent p-type copper iodide (CuI) thin films were fabricated by solid iodization of evaporated Cu precursor layers at room temperature. The effect of the thickness on microstructure, binding energy and optoelectrical properties is systematically studied. X-ray diffraction measurements show the polycrystalline nature of the CuI thin films with zincblende type structure. The X-ray photoelectron spectroscopy (XPS) analysis indicates that the oxidation state of Cu is +1 and the estimated value of [Cu]/[I] at 100 nm is 0.87. Excess iodide ions trap considerable holes, causing CuI thin films to exhibit the p-type conductivity, which is consistent with the results of the Hall effect measurement and the non-linear characteristics of the CuI/ITO structure. Moreover, the CuI thin films with thickness of 100 nm exhibits an ultra-high optical transmittance of 95.5% in the wavelength of 380?780 nm and an excellent conductivity of 34 S/cm. These results prove the great potential of CuI as a promising p-type optoelectronic material.

A thiocyanato-bridged copper(i) cubane complex and its application in palladium-catalyzed Sonogashira coupling of aryl halides

Reaction of copper(i) thiocyanate with 1,1?-bis(di-tert- butylphosphino) ferrocene (dtbpf) in a 2:1 molar ratio in DCM-MeOH (50:50 V/V) afforded a tetranuclear copper(i) complex [Cu4(mu3-SCN) 4(kappa1-P,P-dtbpf)2] (1) with a cubane-like structure. Complex 1 was shown to be an efficient catalyst in comparison to CuI in the Sonogashira reaction. The coupling products were obtained in high yields by using Pd loadings of 0.2 mol% as well as complex-1 of 0.1 mol%.

Antimicrobial, spectral and thermal studies of divalent cobalt, nickel, copper and zinc complexes with triazole Schiff bases

Co(II), Ni(II), Cu(II) and Zn(II) complexes of bidentate Schiff bases derived from the condensation of 4-amino-5-mercapto-3-methyl/ethyl-1,2,4-triazole with 5-nitrofurfuraldehyde were synthesized and tested as antimicrobial agents. The Schiff bases and their metal complexes were characterized by elemental analyses, magnetic moment measurements, spectroscopic (IR, Electronic, 1H NMR, ESR) and thermogravimetric analyses. A square planar geometry for Cu(II) and octahedral geometry for Co(II), Ni(II) and Zn(II) complexes have been proposed. The presence of coordinated water in metal complexes was confirmed by thermal and IR data of the complexes. The Schiff bases and their metal complexes have been screened for antibacterial [Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli, Staphylococcus aureus] and antifungal activities [Aspergillus niger, A. flavus].

Powder pressed cuprous iodide (CuI) as a hole transporting material for perovskite solar cells

This study focuses on employing cuprous iodide (CuI) as a hole-transporting material (HTM) in fabricating highly efficient perovskite solar cells (PSCs). The PSCs were made in air with either CuI or 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD) as HTMs. A simple and novel pressing method was employed for incorporating CuI powder layer between perovskite layer and Pt top-contact to fabricate devices with CuI, while spiro-OMeTAD was spin-coated between perovskite layer and thermally evaporated Au top-contact to fabricate devices with spiro-OMeTAD. Under illuminations of 100 mW/cm2 with an air mass (AM) 1.5 filter in air, the average short-circuit current density (JSC) of the CuI devices was over 24 mA/cm2, which is marginally higher than that of spiro-OMeTAD devices. Higher JSC of the CuI devices can be attributed to high hole-mobility of CuI that minimizes the electron-hole recombination. However, the average power conversion efficiency (PCE) of the CuI devices were lower than that of spiro-OMeTAD devices due to slightly lower open-circuit voltage (VOC) and fill factor (FF). This is probably due to surface roughness of CuI powder. However, optimized devices with solvent-free powder pressed CuI as HTM show a promising efficiency of over 8.0 % under illuminations of 1 sun (100 mW/cm2) with an air mass 1.5 filter in air, which is the highest among the reported efficiency values for PSCs fabricated in an open environment with CuI as HTM.
