Yuan, Jing-Mei;Chen, Nan-Ying;Liao, Hao-Ran;Zhang, Guo-Hai;Li, Xiao-Juan;Gu, Zi-Yu;Pan, Cheng-Xue;Mo, Dong-Liang;Su, Gui-Fa research published 《 3-(Benzo[d]thiazol-2-yl)-4-aminoquinoline derivatives as novel scaffold topoisomerase I inhibitor via DNA intercalation: design, synthesis, and antitumor activities》, the research content is summarized as follows. Twenty-seven 3-(benzo[d]thiazol-2-yl)-4-aminoquinoline derivatives have been designed and synthesized as topoisomerase I inhibitors. The in vitro anti-proliferation evaluation against four human cancer cell lines (MGC-803, HepG-2, T24, and NCI-H460) and one normal cell line (HL-7702) indicated that most of them exhibited potent cytotoxicity. Among them, 5a(I) was identified as the most promising candidate with a low IC₅₀ value of about 2.20 ± 0.14 and was selected for further exploration. Spectroscopic analyses and agarose-gel electrophoresis assays indicated that 5a could interact with DNA and strongly inhibit topoisomerase I (Topo I). Further screening of the Topo I activity of compounds 5b, 5c, 5e, 5f, 5h, 5i, 5j, 5l, and 5n suggested that some of the compounds might exert quite a different cytotoxicity profile to that of 5a. Mol. modeling studies confirmed that 5a adopts a unique mode to interact with DNA and Topo I. Other mol. mechanistic studies suggested that the treatment of MGC-803 cells with 5a induces S phase arrest, up-regulates the pro-apoptotic protein, down-regulates the anti-apoptotic protein, activates caspase-3, and subsequently induces mitochondrial dysfunction so as to induce cell apoptosis. The in vivo efficiency of 5a was also evaluated on MGC-803 xenograft nude mice and the relative tumor growth inhibition was 42.4% at 12 mg kg^-1 without an obvious loss in the body weight

Yoshie, Kensuke;Yada, Shuichi;Ando, Shuichi;Ishihara, Kazuhiko research published 《 Chemical Structural Effects of Amphipathic and Water-soluble Phospholipid Polymers on Formulation of Solid Dispersions》, the research content is summarized as follows. For the polymeric carriers of solid dispersions, it is important that carriers themselves dissolve quickly and maintain the supersaturated state of amorphous drugs during their dissolution period to improve bioavailability. Amphipathic 2-methacryloyloxyethyl phosphorylcholine (MPC) polymers can be dissolved in water, owing to the extremely high hydrophilicity of the MPC units, and are used as an ideal feeder for drug mols. to form aggregates in aqueous conditions. We synthesized amphipathic MPC copolymers with different hydrophobic side chains and molar ratios of MPC units, and evaluated the effect of the polymers on dissolution rate and supersaturation maintenance of solid dispersions of indomethacin. In most of the water-soluble amphipathic MPC copolymers, “spring-parachute”-like dissolution behavior was observed, where the drug initially became supersaturated followed by slow precipitation In particular, MPC copolymers with aromatic rings in their side chains or polymers with a high percentage of hydrophobic units remained in a supersaturated state for a longer period. In contrast, urethane groups, which form hydrogen bonds with drug mols., could also interact with water and were not conducive to maintaining supersaturation In addition, water solubility of the polymer is important for rapid dissolution

In this study, volatile profiles and taste properties of Harbin red sausages prepared with traditional and conventional processing methods were evaluated using solid-phase microextraction gas chromatog.-mass spectrometry (SPME-GC/MS) coupled with electronic nose (E-nose) and electronic tongue (E-tongue). Four varieties of traditional sausages and four varieties of conventional sausages were selected. A total of 131 volatiles were identified, of which 50 were found in all sausages, and of which 77 were significantly different between traditional sausages and conventional sausages. The total contents of aldehydes (211.32μg/kg), ketones (404.28μg/kg), phenols (1795.40μg/kg) and furans (928.73μg/kg) in the traditional sausages were significantly higher than those in the conventional sausages (P < 0.05). The results of GC/MS coupled with E-nose based on principal component anal. could discriminate the sausages well, but the E-tongue could not clearly distinguish them.

In this study, the volatile profiles of Harbin red sausages smoked with pear, oak, apple and beech woodchips were evaluated using the combination of solid-phase microextraction gas chromatog.-mass spectrometry (SPME-GC/MS) and electronic nose (E-nose). Comparisons of the color, texture profile and sensory attributes were also conducted. The E-nose data and GC/MS data were analyzed by principal component anal. (PCA), resp. The correlation between E-nose sensor responses and volatile compounds was evaluated with partial least squares regression (PLSR). The results showed that the smoking process played an important role in the formation of volatile compounds of Harbin red sausage. The smoking process caused an increase in the intensity of smoky odor, and the sausage smoked with different woodchips showed higher smoky odor compared with the unsmoked sausage (P < 0.05). A total of 87 volatile compounds were identified by GC/MS. According to the odor activity values, the characteristic odor of the Harbin red sausages mainly resulted from 22 volatile compounds PCA of the volatile compounds and E-nose sensors could effectively differentiate sausages that were unsmoked and sep. smoked with different woodchips. Furthermore, the PLSR results (P < 0.05, Q² = 0.619) indicated that there was a high correlation between the E-nose sensors and volatile compounds

A series of highly dispersed cobalt-based catalysts on N-doped ordered porous carbon (Co-NOPC) were synthesized using the sacrificial-template method. MCM-41, ZSM-5 and SBA-15 were employed as hard templates with 2,2′-bipyridine as the ligand. The phys. and chem. properties of the Co-NOPC catalyst were characterized by Raman, XRD, SEM, TEM, EDX, ICP, BET, XPS. Co-NOPC had been proven to be a highly efficient catalyst for oxidative esterification of furfural (FUR) to Me 2-furoate without alk. additives. Catalytic performance was correlated to the dispersed cobalt, porous structure and sp. surface area. The relationship between oxygen activation and the strong interaction of cobalt and pyridine nitrogen were confirmed by XPS. Catalytic performance enhancement mechanisms were correlated with the redistribution of electrons at the interface between carbon material and cobalt atoms through the mol. dynamics method and a reaction mechanism was also proposed. The optimized catalysts showed outstanding catalytic activity and stability and no obvious decrease in activity was found after 6 cycles with 99.6% FUR conversion and 96% Me 2-furoate selectivity.
