Redox-coupled complexation of 23-phospha-21-thiaporphyrin with group 10 metals: A convenient access to stable core-modified isophlorin-metal complexes

Core-modified isophlorin-metal complexes were successfully prepared by redox-coupled complexation of P,S,N2-hybrid porphyrin with zerovalent palladium, nickel, and platinum. In this transformation, the core-phosphorus atom plays crucial roles in enhancing the electron-accepting ability of the 18pi porphyrin ring and stabilizing the 20pi isophlorin ring owing to high P-M affinity. The isolated Pd and Pt complexes are chemically stable under ambient conditions. The Pd-P,S,N2 isophlorin complex was structurally characterized by X-ray crystallography, which revealed a distorted 20pi plane with a square planar palladium(II) center. Experimental (1H, UV-vis, and X-ray) and theoretical (density functional theory calculations) results suggest that the P,S,N2-isophlorin-metal complexes possess nonaromaticity in terms of both magnetic and geometrical criteria.

New building blocks for the noncovalent assembly of homo- and hetero-multinuclear metallodendrimers

Ligands 5 and 8, derived from the coupling of [3,5-bis[(diphenylphosphinyl)methyl]phenyl]-oxy groups to bi- and trifunctional spacers, respectively, were cyclometalated with Pd[CH3-CN]4(BF4)2, cis-[PtCl2(PPh3)2], or NiCl2·-6H2O. The cationic Pd and Pt complexes were converted into overall neutral Pd-Cl and Pt-Cl complexes. The resulting pincer complexes can be used as building blocks for the controlled assembly of both homo- and hetero-multinuclear metallodendrimers. The 31P NMR spectra of the pincer complexes exhibit different shifts for chloride, H2O, or nitrile occupying the fourth coordination site, making the 31P chemical shift an excellent diagnostic tool for the assembly process.

Design, Synthesis, Structure-Activity Relationship Studies, and Three-Dimensional Quantitative Structure-Activity Relationship (3D-QSAR) Modeling of a Series of O-Biphenyl Carbamates as Dual Modulators of Dopamine D3 Receptor and Fatty Acid Amide Hydrolase

We recently reported molecules designed according to the multitarget-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH-D3R target combination in preliminary studies. We have rationalized the structural features conducive to activities at the main targets and investigated activities at two off-targets: dopamine receptor subtype D2 and endocannabinoid receptor CB1. To understand the unexpected affinity for the CB1 receptor, we devised a 3D-QSAR model, which we then prospectively validated. Compound 33 was selected for PK studies because it displayed balanced affinities for the main targets and clear selectivity over the two off-targets. 33 has good stability and oral bioavailability and can cross the blood-brain barrier.

Supramolecular assemblies with symmetrical octahedral structures – Synthesis, characterization, and electrochemical properties

Functional nanosized cage complexes with an octahedral framework have been synthesized by the facile self-assembly reactions of six 90 Pd II-containing compounds {[Pd(dppf)(OTf)2] or [Pd(PPh 3)(OTf)2], dppf = 1,1?-bis(diphenylphosphanyl) ferrocene, OTf = trifluoromethylsulfonate} and four 120 functional tritopic ligands [2,4,6-tri(4-pyridyl)-1,3,5-triazine] in acetone. Diffusion-ordered NMR spectroscopy (DOSY) and AFM images clarify the formation of 3-4 nm nanoparticles. These highly symmetrical cage complexes are discrete, face-directed, functional nanoparticles with symmetrical octahedral structures. The self-assembled functional cage complexes exhibit interesting electrochemical activities, and thus will potentially be useful in the catalysis of redox reactions, the encapsulation of sizeable guest molecules and the control of organic synthetic reactions. The appropriate stoichiometric combination of 90 PdII-containing units with 120 tritopic units affords octahedral symmetrical nanocages through covalently linked functional groups, which exhibit interesting electrochemical activities.

Synthesis, electrochemical, and molecular inclusion properties of ‘canopied’ trinuclear ruthenium complexes with six anchoring groups on an ITO electrode

New trinuclear Ru complexes bearing both 1,3,5-tris(2,2?:6?, 2?-terpyridyl)benzene and bis(benzimidazol-2-yl)pyridine with six phosphonate anchors were synthesised and immobilised on an ITO electrode. The ‘canopied’ structure was proved by AFM measurements. The immobilised Ru trinuclear complex revealed a one step three-electron oxidation process for the Ru(II/III) couple at around +0.9 V vs. Ag/AgCl, indicating that the Ru-Ru interaction is small. For the Ru immobilised ITO surface, the electron transfer blocking and the electron mediation of [Fe(CN)6]4- oxidation through the Ru(iii)Ru(ii) catalytic cycle are strongly dependent on the alkyl chain length. The spectroelectrochemistry of the Ru trinuclear complex monolayer on the ITO electrode showed a stable electrochromic response under the potential pulse. The present ‘canopied’ Ru trinuclear complexes hold a small cavity that encapsulates tetrathiafulvalene molecules, which can be proved by a cyclic voltammogram.

Group 10 metal complexes supported by pincer ligands with an olefinic backbone

The coordination chemistry of 2,2?-bis(di-iso-propylphosphino)-trans- stilbene (tPCH-CHP) with group 10 metal centers in a variety of oxidation states is reported; different coordination modes were observed depending on the oxidation state of the metal. With metal centers in the 0 or +1 oxidation state ((tPCH-CHP)Ni, [(tPCH-CHP)Pd]2, (tPCH-CHP)NiCl, (tPCH-CHP)NiI), eta2 coordination of the olefin occurs, whereas, with metals in the +2 oxidation state, C-H activation of the backbone, followed by rapid H-X reductive elimination, was observed, leading to an eta1 coordination of the backbone in (tPC-CHP)MCl (M = Ni, Pd, Pt). Employing the methyl-substituted analogue, 2,2?-bis(di-iso-propylphosphino)-trans- diphenyl-1,2-dimethylethene (tPCMe-CMeP), forced an eta2 coordination of the olefin in [(tPCMe-CMeP)NiCl]2[NiCl4]. The synthesis of the hydride complex (tPC-CHP)NiH was attempted, but, instead, led to the formation of (tPCH-CHP)Ni, indicating that the vinyl form of the backbone can function as a hydrogen acceptor. All metal complexes were characterized by multinuclei NMR spectroscopy, X-ray crystallography, and elemental analysis.

6-Polyamino-substituted quinolines: Synthesis and multiple metal (CuII, HgII and ZnII) monitoring in aqueous media

Chemoselective palladium-catalyzed arylation of polyamines with 6-bromoquinoline has been explored to prepare chelators for the detection of metal cations in aqueous media. The introduction of a single aromatic moiety into non-protected polyamine molecules was achieved using the commercially available Pd(dba)2/BINAP precatalyst to afford nitrogen chelators, in which the aromatic signalling unit is directly attached to the polyamine residue. Water-soluble receptors were then synthesized using N-alkylation of these polyamines by hydrophilic coordinating residues. By combining rich photophysical properties of the 6-aminoquinoline unit with a high coordination affinity of chelating polyamines and a hydrophilic character of carboxamido-substituted phosphonic acid diesters in a single molecular device, we synthesized chemosensor 5 for selective double-channel (UV-vis and fluorescence spectroscopies) detection of CuII ions in aqueous media at physiological levels. This receptor is suitable for the analysis of drinking water and fabrication of paper test strips for the naked-eye detection of CuII ions under UV-light. By increasing the number of donor sites we also obtained chemosensor 6 which is efficient for the detection of HgII ions. Moreover, chemosensor 6 is also suitable for multiple detection of metal ions because it chelates not only HgII but also CuII and ZnII ions displaying different responses of emission in the presence of these three cations.
