Abstract:
A platinum-catalyzed syn-stereocontrolled ring-opening reaction of oxabicyclic alkenes with arylsulfonyl hydrazides was developed. This protocol exhibited high efficiency and good functional group tolerance, affording cis-2-aryl-1, 2-dihydronaphthalen-1-ols (3) or 2-aryl-naphthalenes (4) as dehydrated products in good to excellent yields under mild conditions (up to 89%). In addition, the cis-1, 2-configuration of product (1S*, 2R*)-6, 7-dibromo-2-(p-tolyl)-1, 2-dihydronaphthalen-1-ol (3db) was confirmed by X-ray single crystal diffraction analysis. Based on the results, a plausible mechanism for the ring-opening reaction was proposed. Remarkably, arylsulfonyl hydrazides were used as carboanion nucleophiles in the ring-opening reaction via releasing N2 and SO2 in situ.

[Abstract](2920) [FullText HTML] [PDF 1940KB](45)
Abstract:
Thirty-six unreported pyrimidine analogues were designed, synthesized and characterized by IR, 1H NMR, 13C NMR and HRMS. Their antifungal activities were determined against five plant pathogenic fungi namely Rhizoctonia solani, Fusarum graminearum, Helminthosporium maydis, Sclerotinia sclerotiorum and Botrytis cinerea. The results indicated that most of them revealed significant antifungal activities at 20 mg/L. Among them, 4-(furan-2-yl)-2-methyl-6-(p-tolyl)pyrimidine (2c) and 4-(4-chlorophenyl)-6-(5-methylfuran-2-yl)-2-(1H-pyrazol-1-yl)pyrimidine (3d) showed the strongest activities against Sclerotinia sclerotiorum and their median effect concentrations (EC50) were 0.072 and 0.077 mg/L, respectively, which implied that they had better antifungal activities than the commercial fungicide fluopyram (EC50=0.244 mg/L). Meanwhile, the inhibitory activities of compounds 2c and 3d were determined against succinate dehydrogenase (SDH). The results exhibited that their half inhibitory concentrations (IC50) were 0.115 and 0.121 mg/L, respectively, indicating that they also had better inhibitory activities than fluopyram (IC50=0.356 mg/L). Molecular docking studies demonstrated that the binding energy of compounds 2c, 3d and fluopyram to SDH was -32.2 kJ/mol, -31.8 kJ/mol and -28.9 kJ/mol, respectively, which represented that they had stronger affinities than fluopyram. The inhibitory activities of compounds 2c and 3d against SDH have been reported for the first time.

Abstract:
聚氨酯材料被广泛用于植入导管及药物载体等生物医用领域,但在一些使用环境中,其血液相容性仍然不能达到要求.以聚四氢呋喃醚二元醇(PTMG)、聚碳酸酯二元醇(PC)为软段,异佛尔酮二异氰酸酯(IPDI)为硬段,1,4-丁二醇(BDO)、二甲硫基甲苯二胺(E300)为扩链剂,设计合成了具有良好血液相容性的聚氨酯弹性体.对合成的聚氨酯弹性体进行红外光谱(FT-IR)、差示扫描量热分析(DSC)、力学性能和水接触角的测试,并进行了溶血实验和细胞相容性实验.结果表明,所合成的聚氨酯弹性体具有良好的机械力学性能;溶血和细胞相容性实验显示该材料具有优良的血液相容性.特别是选用IPDI和E-300扩链剂作硬段、PC作软段的聚氨酯弹性体的综合性能最佳,在生物医疗等领域具有一定的应用前景.

Abstract:
By silica gel, Sephadex LH-20 column chromatography as well as preparative high performance liquid chromatography (HPLC), four previously undescribed α-pyrones sharing same primary structure were isolated from the brown rice solid medium of Fusarium tricinctum. Their structures were elucidated by spectroscopic analyses and their absolute configurations were finally confirmed by a modified Snatzke's method.

Abstract:
Two reaction-based water-soluble boron-dipyrromethene (BODIPY) fluorescent probes, Ac-Phe-BODIPY and Ac-BODIPY, were developed for peroxynitrite (ONOO-) measurement. High sensitivity, low detection limit and excellent selectivity toward ONOO- were obtained for determining reactive oxygen species (ROS) and reactive nitrogen species (RNS). The reaction-based probe Ac-Phe-BODIPY was hydrolyzed into BODIPY-1 which was isolated by column chromatography and proved by 1H NMR and ESI-MS. The characterization results revealed the photoinduced electron transfer (PET) mechanism which was simultaneously in agreement with density functional theory (DFT) calculation.
