A multiblock copolymer with increased charge density in the hydrophilic phase was synthesized by utilizing a trisulfonated poly(arylene ether sulfone) backbone (SHQS100). To achieve a balance of membrane properties a partially fluorinated poly(arylene ether benzonitrile) hydrophobic phase (6FPAEB) was used in uneven block lengths to form the hydrophilic-hydrophobic multiblock copolymer. Multiblock copolymers were synthesized via nucleophilic aromatic substitution to achieve high molecular weight copolymers and corresponding ductile membranes. Combination of the shorter increased charge density hydrophilic phase and longer partially fluorinated hydrophobic phase resulted in superior proton conductivity and mechanical properties while limiting water uptake and swelling, despite high ion-exchange capacity. The trifunctional SHQSH hydrophilic phase is proposed to produce a more concentrated charge region in the hydrophilic phase, while swelling of the membrane was limited by a longer partially fluorinated hydrophobic phase.

An unprecedented Ag-I-catalyzed efficient method for the coupling of imino ethers and enol diazoacetates through a [3+2]-cycloaddition/C-O bond cleavage/[1,5]-proton transfer cascade process is reported. The general class of imino ethers that includes oxazolines, benzoxazoles and benzimidates are applicable substrates for these reactions that provide direct access to fully substituted pyrroles with uniformly high chemo- and regioselectivity. High variability in substitution at the pyrrole 2-, 5- and N-positions characterizes this methodology that also presents an entry point for further pyrrole diversification via facile modification of resulting N-functional pyrroles.

Aggregation-induced emission luminogens (AlEgens) have attracted increasing attention in recent years on account of their attribute of overcoming the aggregation-caused quenching (ACQ) phenomenon of conventional organic fluorophores. Despite their remarkable advantages and great developments, most organic AlEgens exhibit broad emission spectra with the full width at half-maxima (FWHM) over 100 nm, which is to the disadvantage of their practical applications. Herein, supramolecular polymeric AIE materials with brighter fluorescence and narrower emission band (higher color purity) than conventional AlEgens were developed by taking advantage of the light-harvesting strategy. These AIE materials, including nanoparticles, microfibers, and thin films, were fabricated from supramolecular polymers comprising quadruple hydrogen-bonded monomer tetraphenylethylene (TPE) and borondipyrromethene (BODIPY) as antenna chromophores and as energy acceptors, respectively. The excitation energy collected by TPE molecules was efficiently transferred to the BODIPY, resulting in up to 6 fold enhanced fluorescence intensity and narrowed emission band with FWHM decreasing from 148 to 32 nm. The resulting nanoparticles showed similar to 5-fold higher brightness than commercial quantum dots. The highly fluorescent nanoparticles were successfully applied for in vitro and in vivo fluorescence and chemiluminescence imaging, showing superior imaging performance to conventional AIE nanoparticles.

Galat reactions between aldehydes and substituted malonic acids half oxyester were found to be efficiently catalyzed by morpholine in refluxing toluene. This transformation allows the stereoselective synthesis of diverse alpha,beta-disubstituted acrylates in moderate to good yields. This method constitutes an attractive alternative to existing methods in terms of scope and eco-compatibility.

Inhibition of the host RNA polyadenylating polymerases, PAPD5 and PAPD7 (PAPD5/7), with dihydroquinolizinone, a small orally available, molecule, results in a rapid and selective degradation of hepatitis B virus (HBV) RNA, and hence reduction in the amounts of viral gene products. DHQ, is a first in class investigational agent and could represent an entirely new category of HBV antivirals. PAPD5 and PAPD7 are noncanonical, cell specified, polyadenylating polymerases, also called terminal nucleotidyl transferases 4B and 4A (TENT4B/A), respectively. They are involved in the degradation of poor-quality cell transcripts, mostly noncoding RNAs and in the maturation of a sub-set of transcripts. They also appear to play a role in shielding some mRNA from degradation. The results of studies with DHQ, along with other recent findings, provide evidence that repression of the PAPD5/7 arm of the cell RNA quality control pathway, causes a profound (multifold) reduction rather than increase, in the amount of HBV pre-genomic, pre-core and HBsAg mRNA levels in tissue culture and animal models, as well. In this review we will briefly discuss the need for new HBV therapeutics and provide background about HBV transcription. We also discuss cellular degradation of host transcripts, as it relates to a new family of anti-HBV drugs that interfere with these processes. Finally, since HBV mRNA maturation appears to be selectively sensitive to PAPD5/7 inhibition in hepatocytes, we discuss the possibility of targeting host RNA quality control as an antiviral strategy.

Modular beta-borylacrylates have been validated as programmable, ambiphilic C-3-synthons in the cascade annulation of 2-halo-phenol derivatives to generate structurally and electronically diverse coumarins. Key to this [3+3] disconnection is the BPin unit which serves a dual purpose as both a traceless linker for C(sp(2))-C(sp(2)) coupling, and as a chromophore extension to enable inversion of the alkene geometry via selective energy transfer catalysis. Mild isomerisation is a pre-condition to access 3-substituted coumarins and provides a handle for divergence. The method is showcased in the synthesis of representative natural products that contain this venerable chemotype. Facile entry into pi-expanded estrone derivatives modified at the A-ring is disclosed to demonstrate the potential of the method in bioassay development or in drug repurposing.

Background: Cancer continues to be the major health burden worldwide. There is an urgent need for the development of novel antineoplastic compounds to treat this devastating condition. Various alkylating anticancer drugs have been employed in the clinic for treating cancers. Unsaturated conjugated ketones are a group of alkylators which are of significant interest as potent antineoplastic agents. Objective: The goal of this study is to discover unsaturated conjugated ketones which are novel potent cytotoxins displaying growth-inhibitory properties towards neoplasms and also to serve as cytotoxic warheads in drug development. Methods: A variety of 3,5-bis (benzylidene)-4-piperidones 2a-n were synthesized and evaluated against a number of neoplastic cell lines. The short-term neurotoxicity of 2a-k, n was evaluated in mice by i.p. administration using doses level of 30, 100 and 300 mg/kg. Statistical correlations for determining structure-activity relationships were performed using an SPSS software. Results: A number of compounds display cytotoxic potencies in the region of 10(-7) to 10(-8) M and some of the structural features contributing to the cytotoxicity were identified. Compounds 2a-d, 2h demonstrated substantially higher cytotoxic potencies compared to melphalan and 5-fluorouracil against a panel of leukemic and colon cancer cell lines. These lead cytotoxins comply with drug-likeness properties. In general, the antineoplastics 2 are well tolerated in mice using a short-term neurotoxicity screening. Conclusion: In general, this group of compounds comprises excellent cytotoxic agents, which warrant their further development as cytotoxic warheads.

Nitroso derivative of 2,7-diaryl-1,4-diazepan-5-ones 9-12 are synthesized and characterized using spectroscopic techniques such as IR, EI-MS and NMR spectra. The stereochemical investigation of nitroso compounds has been carried out with 1D (H-1, C-13 & DEPT-135) and 2D (COSY & HSQC) NMR spectral data. Rotational isomers (syn and anti rotamers) of 9-12 are identified and categorized by room temperature NMR spectral studies. Furthermore, the conformation of the ring and the orientation of N-N= O function have been arrived on the basis of chemical shifts, coupling constants and dihedral angles. In solution state, syn and anti rotamers of the compounds 9-11 exist in equilibrium between flattened boat conformation with quasi-axial orientations of the aryl groups at C-2 and C-7. Nevertheless, compound 12 and its syn and anti rotamers prefer to adopt equilibrium between chair conformations with axial orientation of aryl substituents. In order to validate the solution state conformation, the compound 12 is crystallized and the crystal structure is solved by single crystal XRD study. The compound 12 exists in an alternate chair conformation and aryl groups at C-2 & C-7 occupy axial orientations in solid state also. (C) 2020 Elsevier B.V. All rights reserved.
