摘要:以9, 10-菲醌、对苯二甲醛、对氟苯甲醛、对甲氧基苯甲醛、对硝基苯甲醛及吡咯等为主要原料,设计合成了双核卟啉(P2-PPI)。通过FTIR光谱、1HNMR和13CNMR表征了其结构,利用UV-Vis光谱、荧光光谱测试了其光谱特征。UV-Vis光谱测试表明,双核卟啉(P2-PPI)Soret带的摩尔消光系数是对应单核卟啉(P1)的2.85倍,光谱吸收范围显著变宽;在浓度测试范围内,双核卟啉P2-PPI的聚集形态未改变。同浓度下,荧光光谱测试表明,双核卟啉P2-PPI中菲并咪唑部分的荧光强度仅为菲并咪唑前驱体的1/3,卟啉单元的荧光强度是单体卟啉的2倍。通过循环伏安法测试并比较了P2-PPI和P1的电化学性质,并结合光化学带隙计算了ELUMO和EHOMO值,分别与TiO2和I-/I3-氧化还原电对能级匹配。

Abstract:The target binuclear porphyrin P2-PPI was synthesized by raw materials of 9, 10-phenanthrenequinone, 4-fluorobenzaldehyde, 1, 4-phthalaldehyde, anisic aldehyde, 4-nitrobenzaldehyde, and pyrrole. The structures of all compounds were characterized by IR and 1HNMR, and the spectral characteristics of P2-PPI is studied by UV-Vis and fluorescence spectra. Results showed that molar extinction coefficient of the target binuclear porphyrin P2-PPI was 2.85 times as high as the mononuclear porphyrin P1, and occupied broader spectral absorption range than P1. And in the range of concentration test, the aggregation behaviors of P2-PPI remained unchanged. Fluorescence spectrum indicated that the intensity of the phenanthrenequinone unit of P2-PPI was only two-third smaller than phenanthrenequinone precursor, and the intensity of theporphyin unit of P2-PPI was 2 times as high as mononuclear porphyrin. The electrochemical properties of P2-PPI and P1were tested and compared with cyclic voltammetry. Also, the LUMO and HOMO energy levels were calculated combined with photochemical band gap, matching with the conductive band of TiO2 and the redox energy level of I-/I3-, respectively.

Antimicrobial activity assessment indicates that the compound exhibits selective inhibition against gram-positive bacterial strains. Meanwhile, its minimum inhibition concentration (MIC) against methicillin-resistant Staphylococcus aureus (MRSA) is 1.0 μg/mL, which is superior to that of positive control: vancomycin. Furthermore, we proposed the inhibition mechanism via docking the compound to DNA gyrase.

Abstract:The sterility and radionuclide purity analytical methods of colloidal chromium phosphate [32P] injection were investigated to validate the sterility examination and establish the radionuclide purity analytical method. It was indicated that the direct inoculation method can be used with 0.2 mL samples inoculated into 7.5 mL medium to conduct the sterility analysis. Regarding the radionuclide purity test, radioactive absorbing sleeve was designed and processed, which changed the measurement ratio of main nuclide and impure nuclide. In the work, the activity of γ impurities was measured by the highly purified germanium gamma spectrometer, followed by the analysis of the 32P activity using the activity meter. The radionuclide purity of 32P was eventually calculated based on the activity of 32P and impure nuclide.

Abstract: A 4-hydroxybenzoic acid imprinted column was prepared by in situ photo-initiated and microwave polymerization in a capillary column. The results show that the particle diameter and pore size of monolithic column materials by in situ photo-initiated is larger than microwave irradiation. Meanwhile, the former has good permeability. Good molecular recognition was achieved for p-hydroxybenzoic acid and good resolution of isomers can be realized. In addition, the mode of pressure-driven capillary electrochromatography is needed on the monolithic column by microwave irradiation, caused by small particle diameter and pore size. Furthermore, some neutral compounds could also be baseline-separated on the imprinted polymer columns by photo initiated and microwave irradiation.

Abstract: 2-Chloro-4-nitrophenyl as a very important fluorogenic group has been used for synthesis many glycoside enzyme substrates which are widely applied in the research of its related enzyme inhibitor sandenzyme activities. In this work, a novel compound 2-chloro-4-nitrophenyl-β-D-fucoside has been designed and synthesized as enzyme substrate for β-D-fucosidase. Firstly, D-fucose was synthesized from the commercially inexpensive D-galactose as the starting material in four steps. Secondly, 1-bromo-2, 3, 4-tri-O-acetyl-α-D-fucoside was prepared from D-fucose via acetylization and bromination. Thirdly, the 1-bromo-2, 3, 4-tri-O-acetyl-α-D-fucoside was coupled to fluorescein 2-chloro-4-nitrophenol to obtain 2-chloro-4-nitrophenyl-2, 3, 4-tri-O-acetyl β-D-fucoside in the way of stereoselectivity. At last, the target compound 2-chloro-4-nitrophenyl-β-D-fucoside was obtained from 2-chloro-4-nitrophenyl-2, 3, 4-tri-O-acetyl-β-D-fucoside via deacetylation.

Abstract: The industrial process for the preparation of 2-methylnaphthalene-1, 4-dione is from 2-methylnaphthalene oxidized by sulfuric acid /chromic anhydride (or sodium dichromate). But the method generates a large amount of chromium-containing waste water, which seriously pollutes the environment. In this work, a new method of synthesis of 2-methylnaphthalene-1, 4-dione from 2-methylnaphthalene using cobalt(Ⅱ) nitrate as catalyst and oxone as oxidant was investigated. The results showed, under the optimized reaction conditions, 5 mol% of cobalt(Ⅱ) nitrate catalyst, oxone oxidant, CH3CN/H2O solvent, 25 ℃ reaction temperature, and 16 h reaction time, the conversion of 2-methylnaphthalene and the yield of 2-methylnaphthalene-1, 4-dione could reached 82.6% and 51.2%, respectively. The reaction could proceed at room temperature with the advantages of green, environmental protection, energy-saving and high-efficiency.
