SIRT6 is a deacetylase of histone H3 and inhibitors of SIRT6 have been thought as potential agents for treatment of diabetes. Herein we report the discovery of a series of new SIRT6 inhibitors containing the skeleton 1-phenylpiperazine. Among them, compound 5-(4-methylpiperazin-1-yl)-2-nitroaniline (6d) is the most potent one, which showed an IC50 value of 4.93 mu M against SIRT6 in the Fluor de Lys (FDL) assay. It displayed K-D values of 9.76 mu M and 10 mu M in surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC) assays, respectively. In selectivity assay, 6d showed no activity against other members of the HDAC family (SIRT1-3 and HDAC1-11) at concentrations up to 200 mu M. In a mouse model of type 2 diabetes, 6d could significantly increase the level of glucose transporter GLUT-1, thereby reducing blood glucose. Overall, this study provides a promising lead compound for subsequent drug discovery targeting SIRT6.

Porous polymers have attracted tremendous interest in lithium-sulfur batteries due to the combination of good physical confinement and chemical immobilization to suppress the polysulfide shuttle. Currently, the development of facile and effective methods for fabrication of porous polymers with hierarchical porous structures, strong polar species, and efficient charge-transfer pathways is significant yet challenging, which is crucial for high-performance sulfur cathodes. Herein, for the first time, we present the successful development of a novel class of advanced hierarchical porous polymer nanosheets (AHPPNs) based on a union of surface-initiated atom transfer radical polymerization and a cross-linking-induced coassembly strategy. Due to their well-defined nanoarchitectures, AHPPNs are capable of providing a commendable shuttle-suppressing shield for polysulfides via strong chemisorption, hierarchical porous structures for immobilizing sulfur and relieving volume change, and shortened pathways for ions and electrons. Benefiting from these synergistic effects, the lithium-sulfur batteries assembled with S@AHPPNs cathodes exhibit greatly enhanced rate performance and long stable cycle capability.

Purine nucleotides such as ATP and ADP are important extracellular signaling molecules in almost all tissues activating various subtypes of purinoreceptors. In the brain, the P2Y(1) receptor (P2Y(1)R) subtype mediates trophic functions like differentiation and proliferation, and modulates fast synaptic transmission, both suggested to be affected in diseases of the central nervous system. Research on P2Y(1)R is limited because suitable brain-penetrating P2Y(1)R-selective tracers are not yet available. Here, we describe the first efforts to develop an F-18-labeled PET tracer based on the structure of the highly affine and selective, non-nucleotidic P2Y(1)R allosteric modulator 1-(2-[2-(tert-butyl)phenoxy]pyridin-3-yl)-3-[4- (trifluoromethoxy)phenyl]urea (7). A small series of fluorinated compounds was developed by systematic modification of the p-(trifluoromethoxy)phenyl, the urea and the 2-pyridyl subunits of the lead compound 7. Additionally, the p-(trifluoromethoxy)phenyl subunit was substituted by carborane, a boron-rich cluster with potential applicability in boron neutron capture therapy (BNCT). By functional assays, the new fluorinated derivative 1-{2-[2-(tert-butyl)phenoxy]pyridin-3-yl}-3-[4-(2-fluoroethyl) phenyl]urea (18) was identified with a high P2Y(1)R antagonistic potency (IC50 = 10 nM). Compound [F-18] 18 was radiosynthesized by using tetra-n-butyl ammonium [F-18]fluoride with high radiochemical purity, radiochemical yield and molar activities. Investigation of brain homogenates using hydrophilic interaction chromatography (HILIC) revealed [F-18]fluoride as major radiometabolite. Although [F-18]18 showed fast in vivo metabolization, the high potency and unique allosteric binding mode makes this class of compounds interesting for further optimizations and investigation of the theranostic potential as PET tracer and BNCT agent.

Cyclic aminomethylphosphines in general and 1,5-diaza-3,7-dihposphacyclooctanes in particular are widely used for the design of d(10)-metal complexes with catalytic or luminescent properties. 1,5-Diaza-3,7-diphosphacyclooctanes are chelating ligands towards Ni subgroup metals and chelating or bridging ligands towards copper subgroup metals. These ligands can be utilized for the design of polynuclear complexes with stimuli-responsive luminescence. Nowadays several complexes based on 1,5-diaza-3,7-diphosphacyclooctanes demonstrating stimuli-response of emission towards organic substrates or temperature are known. Some of the gold(I) complexes are able to sensitize the luminescent anionic rhenium cluster. Copper(I) complexes display rather strong luminescence with quantum yields 20-40%. [GRAPHICS] .

An in situ formed cobalt catalyst is developed from cobalt(II)bromide, bis[2-(diisopropylphosphino)-4-methylphenyl]amine and zinc metal. The catalyst mediates the acceptorless dehydrogenative coupling of alcohols and amines into imines with the release of hydrogen gas and the transformation is applied to the synthesis of a variety of imines from different alcohols and amines. The mechanism is investigated with labelled substrates and based on the results a cobalt(I) PNP complex is believed to be the catalytically active species which abstracts hydrogen gas from the alcohol through a metal ligand bifunctional pathway.

Supported by their involvement in many neurodegenerative disorders, muscarinic acetylcholine receptors ( mAChRs) are an interesting target for PET imaging. Nevertheless, no radiotracer is established in clinical routine. Within this work we aim to develop novel PET tracers based on the structure of arecoline. Fifteen novel arecoline derivatives were synthesized, characterized and tested for their affinity to the mAChRs M1-M5 and the conceivable off-target acetylcholinesterase. Five arecoline derivatives and arecoline were labeled with carbon-11 in good yields. Arecaidine diphenylmethyl ester (3b), arecaidine bis(4-fluorophenyl)methyl ester (3c) and arecaidine (4-bromophenyl)(4-fluorophenyl)methyl ester (3e) showed a tremendous gain in mAChR affinity compared to arecoline and a pronounced subtype selectivity for M1. Metabolic stability and serum protein binding of [C-11] 3b and [C-11] 3c were in line with properties of established brain tracers. Nonspecific binding of [C-11]3c was prevalent in kinetic and endpoint experiment on living cells as well as in autoradiography on native mouse brain sections, which motivates us to decrease the lipophilicity of this substance class prior to in vivo experiments.
