Bi, Shuai;Zhang, Zixing;Meng, Fancheng;Wu, Dongqing;Chen, Jie-Sheng;Zhang, Fan research published 《 Heteroatom-Embedded Approach to Vinylene-Linked Covalent Organic Frameworks with Isoelectronic Structures for Photoredox Catalysis》, the research content is summarized as follows. Embedding heteroatoms into the main backbones of polymeric materials has become an efficient tool for tailoring their structures and improving their properties. However, owing to comparatively harsh heteroatom-doping conditions, this has rarely been explored in covalent organic frameworks (COFs). Herein, upon aldol condensation of a trimethyl-substituted pyrylium salt with a tritopic aromatic aldehyde, a two-dimensional oxonium-embedded COF with vinylene linkages was achieved, which was further converted to a neutral pyridine-cored COF by in situ replacement of oxonium ions with nitrogen atoms under ammonia treatment. The two heteroatom-embedded COFs are conceptually isoelectronic with each other, featuring similar geometric structures but different electronic structures, rendering them capable of catalyzing the visible-light-promoted multi-component synthesis of tri-substituted pyridine derivatives with good recyclability.

Background The side reactions of dehalogenation or C-N coupling tend to occur when halogenated aromatic amines are prepared by catalytic hydrogenation reduction of halogenated aromatic nitro compounds. In this paper, we prepared the sub-microspherical Fe3O4@PDA-Pd NPs catalyst apply it efficiently in the hydrogenation reduction of halogenated aromatic nitro compounds to prepare the halogenated aromatic amines under atmospheric pressure. The catalyst shows a high selectivity of greater than 96% and can effectively inhibit the occurrence of the side reactions of dehalogenation and C-N coupling. Results The optimum condition of the hydroreduction reaction is when tetrahydrofuran is used as solvent and the reaction happens at 50 degrees C for 5 h. The selectivity of the chlorinated aromatic amine and the fluorinated aromatic amine products exceed 99% and the yield exceeds 90%. Only a small amount of dehalogenated products and C-N coupling by-products were produced in the brominated aromatic compound and the iodinated aromatic compound. Conclusion We developed a promising method for preparing the superparamagnetic and strongly magnetic Fe3O4@PDA core-shell sub-microsphere-supported nano-palladium catalyst for catalyzing the hydrogenation reduction of halogenated aromatic nitro compounds. The halogenated aromatic amines were efficiently and highly selectively prepared under atmospheric pressure, with the side reactions of dehalogenation and C-N coupling effectively inhabited simultaneously.

A protocol for solvent-free and additive-free oxidation of primary benzylic C-H bonds with O(2)was presented through adjusting the combination of metalloporphyrins and NHPI as binary catalysts to overcome the deficiencies encountered in current oxidation systems. The effects of reaction temperature, porphyrin structure, central metal, catalyst loading and O(2)pressure were investigated systematically. For the optimized combination of T(2-OCH3)PPCo and NHPI, all the primary benzylic C-H bonds could be functionalized efficiently and selectively at 120 degrees C and 1.0 MPa O(2)with aromatic acids as the primary products. The selectivity towards aromatic acids could reach up to 70-95% in the conversion of more than 30% for most of the substrates possessing primary benzylic C-H bonds in the metalloporphyrin loading of 0.012% (mol/mol). And the superior performance of T(2-OCH3)PPCo among the metalloporphyrins investigated was mainly attributed to its high efficiency in charge transfer and fewer positive charges around central metal Co (II) which favored the adduction of O-2 to cobalt (II) forming the high-valence metal-oxo complex followed by the production of phthalimide N-oxyl radical (PINO) and the initiation of the catalytic oxidation cycle. This work would provide not only an efficient protocol in utilization of hydrocarbons containing primary benzylic C-H bonds, but also a significant reference in the construction of more efficient C-H bonds oxidation systems Graphic Abstract The solvent-free and additive-free oxidation of primary benzylic C-H bonds with O(2)was presented through adjusting the combination of metalloporphyrins and NHPI as binary catalysts, and the highest selectivity towards aromatic acid reached up to 95.1% with the conversion of 88.5% in the optimized combination of T(2-OCH3)PPCo and NHPI.

To develop novel therapeutic agents with anticancer activities, two series of novel 2,4-bismorpholinyl-thieno [3,2-d]pyrimidine and 2-morpholinothieno[3,2-d]pyrimidinone derivatives were designed, synthesized and evaluated for their biological activities. Among them, compound A(12) showed the most potent antitumor activities against HCT116, PC-3, MCF-7, A549 and MDA-MB-231 cell lines with IC50 values of 3.24 mu M, 14.37 mu M, 7.39 mu M, 7.10 mu M, and 16.85 mu M, respectively. Further explorations in bioactivity were conducted to clarify the anticancer mechanism of compound A(12). The results showed that compound A(12) obviously inhibited the proliferation of A549 cell lines and decreased mitochondrial membrane potential, which led to the apoptosis of cancer cells and suppressed the migration of tumor cells.

Background:Licensed therapies for nonalcoholic fatty liver disease (NAFLD) do not yet exist, but clinical trials are testing treatment options. Inclusion criteria often require liver biopsy showing fibrosis (F2/3) or cirrhosis (F4) and nonalcoholic steatohepatitis (NASH). However, histological criteria pose a serious obstacle for recruitment. Aims:Characterize the relevance of liver biopsies in the selection of patients with NAFLD. Methods:Patients between 2013 and 2018 with the ICD-10 code K76.0 were analyzed. Fibrosis was defined by the NASH clinical research network (CRN) fibrosis staging system, NASH by a NAFLD activity score (NAS) >= 4. Predictive factors were determined by logistic regression. Results:Liver biopsy was performed in 87/638 (13.6%) patients (49% female, age 52.5 +/- 14.0, BMI 30.4 +/- 5.9 kg/m(2)). Fibrosis stage F0/F1/F2/F3/F4 was observed inN = 7/47/7/17/9, an NAS >= 4 inN = 27. Fibrosis stage F2/F3 and F4 along with NAS >= 4 was found in 1.7% and 0.5% of cases. Liver stiffness measurement, LSM (OR 2.3 per doubling of value; CI 1.3-4.4,p = .005) and FIB-4 (OR 2.3 per doubling of value; CI 1.2-4.4,p = .012) were significant predictors for fibrosis >= F2. Predictive factors for NASH were not identified. Conclusion:The biopsy rate in NAFLD patients is low and fibrosis >= F2 along with NAS >= 4 only present in a few cases. Transient elastography and FIB-4 are useful to select patients at risk for fibrosis for liver biopsy.
