The synthesis of oxidorhenium(V) complexes 1-3 coordinated by tetradentate iminophenolate ligands H2L1-H2L3 bearing backbones of different rigidity (alkyl, cycloalkyl, and phenyl bridges) allows for the formation of distinct geometric isomers, including a symmetric trans-oxidochlorido coordination motif in complex 3. The complex employing a cycloalkyl-bridged ligand (2) of intermediate rigidity exhibits an interesting solvent-and temperature-dependent equilibrium between a symmetric (trans) isomer and an asymmetric (cis) isomer in solution. The occurrence of a symmetric isomer for 2 and 3 is confirmed by single-crystal X-ray diffraction analysis. Chlorido abstraction from 2 with AgOTf yields the corresponding cationic complex 2a, which does not exhibit an isomeric equilibrium in solution but adopts the isomeric form predominant for 2 in a given solvent. All complexes were, furthermore, employed in three benchmark oxygen-Atom-Transfer (OAT) reactions, namely, the reduction of perchlorate, the epoxidation of cyclooctene, and OAT from dimethyl sulfoxide (DMSO) to triphenylphosphane (PPh3), to assess the influence of the isomeric structure on the reactivity in these reactions. In perchlorate reduction, a clear structural influence was observed, where the trans arrangement in 3 led to the complete absence of activity. In the epoxidation reaction, all complexes led to comparable epoxide yields, albeit higher catalytic activity but lower overall stability of the catalysts with a trans arrangement was observed. In OAT from DMSO to PPh3, also a clear structural dependence was observed, where the trans complex 3 led to full phosphane conversion with an excess of oxidant, while the cis compound 1 was completely inactive.

While medicinal inorganic chemistry has been practised for over 5000 years, it was not until the late 1800s when Alfred Werner published his ground-breaking research on coordination chemistry that we began to truly understand the nature of the coordination bond and the structures and stereochemistries of metal complexes. We can now readily manipulate and fine-tune their properties. This had led to a multitude of complexes with wide-ranging biomedical applications. This review will focus on the use and potential of metal complexes as important therapeutic agents for the treatment of cancer. With major advances in technologies and a deeper understanding of the human genome, we are now in a strong position to more fully understand carcinogenesis at a molecular level. We can now also rationally design and develop drug molecules that can either selectively enhance or disrupt key biological processes and, in doing so, optimize their therapeutic potential. This has heralded a new era in drug design in which we are moving from a single- toward a multitargeted approach. This approach lies at the very heart of medicinal inorganic chemistry. In this review, we have endeavored to showcase how a “multitargeted” approach to drug design has led to new families of metallodrugs which may not only reduce systemic toxicities associated with modern day chemotherapeutics but also address resistance issues that are plaguing many chemotherapeutic regimens. We have focused our attention on metallodrugs incorporating platinum and ruthenium ions given that complexes containing these metal ions are already in clinical use or have advanced to clinical trials as anticancer agents. The “multitargeted” complexes described herein not only target DNA but also contain either vectors to enable them to target cancer cells selectively and/or moieties that target enzymes, peptides, and intracellular proteins. Multitargeted complexes which have been designed to target the mitochondria or complexes inspired by natural product activity are also described. A summary of advances in this field over the past decade or so will be provided.

Synthetic sensing materials (artificial receptors) are some of the most attractive components of chemical/biosensors because of their long-term stability and low cost of production. However, the strategy for the practical design of these materials toward specific molecular recognition in water is not established yet. For the construction of artificial material-based chemical/biosensors, the bottom-up assembly of these materials is one of the effective methods. This is because the driving forces of molecular recognition on the receptors could be enhanced by the integration of such kinds of materials at the ?interfaces?, such as the boundary portion between the liquid and solid phases. Additionally, the molecular assembly of such self-assembled monolayers (SAMs) can easily be installed in transducer devices. Thus, we believe that nanosensor platforms that consist of synthetic receptor membranes on the transducer surfaces can be applied to powerful tools for high-throughput analyses of the required targets. In this review, we briefly summarize a comprehensive overview that includes the preparation techniques for molecular assemblies, the characterization methods of the interfaces, and a few examples of receptor assembly-based chemical/biosensing platforms on each transduction mechanism.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1436-59-5, Name is cis-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 1436-59-5, name: cis-Cyclohexane-1,2-diamine

The complexes CuL2X2 · nH2O (L = trans-1,2-diaminocyclohexane; n = 2 when X is Cl and n = 0 when X is NO3) have been synthesized. The complexes [CuL2(H2O)2]Cl2 (1) and [CuL2(NO3)2] (2) have been characterized by single crystal structural analyses and their thermochromism was studied in the solid state. Single crystal X-ray structure analysis of 1 and 2 shows that in both complexes copper ion possesses distorted (4+2) octahedral geometry with N4O2 chromophore. Complex 1 shows time-dependent reversible discontinuous thermochromism whereas, 2 shows reversible continuous thermochromism in the solid state. The discontinuous thermochromism in 1, is due to the different ligand field strength between H2O and Cl, and is associated with deaquation – anation reaction. The IR and electronic spectra of 2 vary with temperature, indicating reversible continuous thermochromism arising from axial interaction between semi-coordinated nitrate ions and CuN4 plane.

ESR observations were performed for the ternary complexes formed with Na+-TCNE- and 5-O-crown ethers.The temperature dependence of the observed Na hyperfine line width was analyzed by applying Bloch’s two-jump model, and the thermodynamical parameters of the complex formation were determined.The stability of the ternary complexes were found to be much affected by the substitution of either the fused benzene ring or the 2,2′-biphenyldiyl group, which acts as a steric restriction during the optimum metal binding to the flexible crown ring.

In an article, published in an article, once mentioned the application of 1806-29-7, Name is 2,2-Biphenol,molecular formula is C12H10O2, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C12H10O2

In certain neurodegenerative diseases damaging levels of nitric oxide (NO) are produced by neuronal nitric oxide synthase (nNOS). It, therefore, is important to develop inhibitors selective for nNOS that do not interfere with other NOS isoforms, especially endothelial NOS (eNOS), which is critical for proper functioning of the cardiovascular system. While we have been successful in developing potent and isoform-selective inhibitors, such as lead compounds 1 and 2, the ease of synthesis and bioavailability have been problematic. Here we describe a new series of compounds including crystal structures of NOS-inhibitor complexes that integrate the advantages of easy synthesis and good biological properties compared to the lead compounds. These results provide the basis for additional structure-activity relationship (SAR) studies to guide further improvement of isozyme selective inhibitors.

In a Article，once mentioned of 14098-44-3, Formula: C14H20O5

Salts of transition metal cations complexed by 12-crown-4, benzo-15-crown-5 or 18-crown-6 with I3-, I5- and I82- anions, are synthesized and their crystal structures are determined by single X-ray diffraction. The crystal structures of 1, 2 and 3 are built up by three different cations with the compositions [Fe(H 2O)6(1 2c4)6]2+, [Zn(H 2O)2(b 15c5)3]2+, [Zn(H 2O)5(1 8c6)2]2+, and isolated triiodide anions I3-, respectively. Aside from the cations, the isotypic iron and copper compounds (4, 5) contain crystallographically independent V-shaped pentaiodide anions which are linked to dimers by weak interionic contacts. Furthermore, the structures contain centrosymmetric I82- anions. An investigation of possible secondary contacts reveals that the iodine substructure of 4 and 5 consists of essentially isolated octaiodide units.
