Rapid and selective visualization of mitochondrial hypochlorite by a red region water-soluble fluorescence probe

Hypochlorite (-OCl) has long been recognized as an effective microbicidal agent in immune system. Herein, we report the design, preparation and spectral characteristics of a -OCl fluorescent probe (FI-Mito). The probe exhibited remarkable fluorescence turn-on signal in the red region upon -OCl titration with the detection limit as low as 0.9 nM. FI-Mito displayed specific response for -OCl in completely aqueous solution. Meanwhile, the introduction of quaternized pyridine realized mitochondria-targeting ability. FI-Mito was further applied to monitor the generation of endogenous -OCl in the mitochondria of macrophage cells and mice. Therefore, it was established that FI-Mito may serve as a useful molecular tool for -OCl detection in vivo. (C) 2020 Elsevier B.V. All rights reserved.

Development of a new bicyclic imidazole nucleophilic organocatalyst for direct enantioselective C-acylation

A novel chiral nucleophilic organocatalyst easily synthesized from simple starting materials bearing a 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine skeleton has been developed and successfully applied in the direct enantioselective C-acylation of 3-substituted benzofuranones. Its catalytic efficiency was shown to be comparable to that of the previously reported chiral 6,7-dihydro-5H-pyrrolo[1,2-a]imidazole catalyst. A wide range of 3,3-disubstituted benzofuranones, possessing a quaternary stereocenter, were synthesized with high yields and enantioselectivities.

Direct Dearomatization of Pyridines via an Energy-Transfer-Catalyzed Intramolecular [4+2] Cycloaddition

The catalytic dearomatization of pyridines, accessing medicinally relevant N-heterocycles, is of high interest. Currently direct, dearomative strategies rely generally on reduction or nucleophilic addition, thus limiting the architecture of the dearomatized products to a six-membered ring. We herein introduce a catalytic, dearomative cycloaddition reaction with pyridines using photoinduced energy transfer catalysis, thereby advancing dearomatization methodology and increasing the topology of pyridine dearomatization products. This unprecedented method features high yields, broad substrate scope (44 examples), excellent functional group tolerance, and facile scalability. Furthermore, a recyclable and sustainable polymer immobilized photocatalyst was employed. Computational and experimental investigations support a mechanism in which a cinnamyl moiety is promoted to its corresponding excited triplet state through visible-light-mediated energy transfer catalysis, followed by a regioselective and dearomative [4+2] cycloaddition to pyridines. This work demonstrates the contribution of visible light catalysis toward enabling thermally challenging organic transformations.

2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine Induced Colon Injury by Disrupting the Intestinal Bacterial Composition and Lipid Metabolic Pathways in Rats

2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), one of the most abundant heterocyclic amines, is a common carcinogen produced in thermally processed protein-rich foods. Studies have demonstrated that PhIP could induce colon tumors in rodents, leaving mechanisms uncovered. This study aims to investigate the mechanism of PhIP-induced colon injury in a rat model. The results of 16S rRNA gene sequencing and metabolomics showed that PhIP disrupted intestinal bacterial composition and affected the glycerophospholipid metabolism and linoleic acid metabolism. Simultaneously, the lipid metabolism function in the intestinal flora was inhibited by PhIP. Notably, transcriptomics revealed that PhIP remarkably inhibited the expression of gene sets associated with steroid hormone biosynthesis, fatty acid elongation, fatty acid degradation, and glycerolipid metabolism pathways in the colon. The results provide new perspectives to study the mechanism of PhIP-induced colon injury and theoretical bases for further understanding the toxicity of PhIP.

Effect of Polymer Removal on the Morphology and Phase of the Nanoparticles in All-Inorganic Heterostructures Synthesized via Two-Step Polymer Infiltration

Polymer templates play an essential role in the robust infiltration-based synthesis of functional multicomponent heterostructures with controlled structure, porosity, and composition. Such heterostructures are be used as hybrid organic-inorganic composites or as all-inorganic systems once the polymer templates are removed. Using iron oxide/alumina heterostructures formed by two-step infiltration of polystyrene-block-polyvinyl pyridine block copolymer with iron and aluminum precursors from the solution and vapor-phases, respectively, we show that the phase and morphology of iron oxide nanoparticles dramatically depend on the approach used to remove the polymer. We demonstrate that thermal and plasma oxidative treatments result in iron oxide nanoparticles with either solid or hollow morphologies, respectively, that lead to different magnetic properties of the resulting materials. Our study extends the boundaries of structure manipulations in multicomponent heterostructures synthesized using polymer infiltration synthesis, and hence their properties.

Discovery and Biological Evaluation of N-Methyl-pyrrolo[2,3-b]pyridine-5-carboxamide Derivatives as JAK1-Selective Inhibitors

Janus kinase 1 (JAK1) plays a key role in most cytokine-mediated inflammatory and autoimmune responses through JAK/STAT signaling; thus, JAK1 inhibition is a promising therapeutic strategy for several diseases. Analysis of the binding modes of current JAK inhibitors to JAK isoforms allowed the design of N-alkyl-substituted 1-H-pyrrolo[2,3-b] pyridine carboxamide as a JAK1-selective scaffold, and the synthesis of various methyl amide derivatives provided 4- ((cis-1- (4-chlorobenzyl)-2-methylpiperidin-4-yl) amino-N-methyl-1H-pyrrolo[2,3-b]pyridine-5-carboxamide (31g) as a potent JAK1-selective inhibitor. In particular, the (S,S)-enantiomer of 31g (38a) exhibited excellent potency for JAK1 and selectivity over JAK2, JAK3, and TYK2. On investigating the effect of 31g on hepatic fibrosis, it was found that it reduces the proliferation and fibrogenic gene expression of TGF-beta-induced hepatic stellate cells (HSCs). Specifically, 31g significantly inhibited TGF-beta-induced migration of HSCs at 0.25 mu M in wound-healing assays.

Charge carrier and optoelectronic properties of phenylimidazo[1,5-a]pyridine-containing small molecules at molecular and solid-state bulk scales

Various optoelectronic and charge transfer properties of 3-(1H-indol-3-yl)-1-phenylimidazo[1,5-a]pyridine (Comp 1), 1,3-diphenylimidazo[1,5-a]pyridine (Comp 2), and 3-(Anthracen-9-yl)-1-phenylimidazo[1,5-a]pyridine (Comp 3) have been explored at the molecular and solid state bulk level. The absorption and emission spectra (lambda(abs) and lambda(emi)) were calculated by time domain B3LYP/6-311G*, CAM-B3LYP/6-311G*, LC-BLYP/6-311G* and PBE0/6-311G* levels. The hybrid functionals B3LYP and PBE0 successfully reproduced experimental lambda(abs) and lambda(emi) more accurately than the long-range corrected functionals. Effect of indol, phenyl and anthracenyl moieties on various properties of interests has been explored. The indol and phenyl units lead to smaller hole reorganization energies and greater transfer integrals resulting superior hole intrinsic mobility for Comps 1 and 2. The substitution of anthracenyl moiety at phenylimidazo[1,5-a]pyridine core increase the electron affinity and electron transfer integrals while decrease the electron reorganization energy. The n- or p-type charge transfer nature of Comp 3 or Comps 1 and 2 has been explored, respectively. The frontier molecular orbitals, ionization potential, electron affinity, reorganization energy, transfer integral, intrinsic mobility, density of states, dielectric constant, extinction coefficient, refractive indices, reflectivity and conductivity shown that imidazo[1,5-a]pyridine derivatives would be efficient materials to be used in multifunctional organic semiconductor devices.

Theoretical insight into the opposite redox activity of iron complexes toward the ring opening polymerization of lactide and epoxide

The origin of opposite reactivity in the ring-opening polymerizations of lactide (LA) and cyclohexene oxide (CHO) catalyzed by redox-switchable bis(imino)pyridine iron complexes has been computationally elucidated. It is found that larger geometrical deformation accounts for the lower activity of the oxidized form (Fe-ox) of the iron catalyst toward LA polymerization in comparison with the reduced analogue (Fe-red) enabling LA insertion with a moderate energy barrier of 27.1 kcal mol(-1). In contrast, compared with the Fe-red species, the higher activity of Fe-ox toward CHO polymerization could be ascribed to the stronger interaction between Fe-ox and CHO moieties, stabilizing the corresponding transition state. This originated from the higher electrophilicity of Fe-ox, which is more sensitive to the binding of the monomer with higher nucleophilicity, such as CHO. Driven by this theoretical understanding, various Fe-ox analogues were computationally modelled by changing the para-substituents of the initial phenoxyls or modifying the backbone of the bis(imino)pyridine ligand to increase the Lewis acidity (electrophilicity) of such complexes. Expectedly, a lower energy barrier is observed in CHO enchainment mediated by the complexes with electron-withdrawing groups. Notably, such energy barriers positively correlate with the LUMO energies of these complexes with various substituents on the initial phenoxyl groups or on the backbone of the bis(imino)pyridine ligand. These results could provide useful information on the development of redox-switchable polymerization systems.
