Research Progress on the Application of Boron Nitride Nanomaterials in Drug Delivery QI Kai-tong, REN Ting, SUN Guo-hui, Zhang Na, ZHAO Li-jiao*, ZHONG Ru-gang (Beijing Key Laboratory of Environment and Viral Oncology, Beijing University of Technology, Beijing 100124, China)
Abstract: Boron nitride (BN) nanomaterials, as a new generation of drug carriers, have recently emerged as novel drug delivery systems due to their unique structural characteristics and excellent physicochemical properties. This article systematically reviewed the latest advances in the synthesis and drug delivery of BN nanotubes, nanosheets and porous materials. Studies have shown that BN materials not only have an extremely high specific surface area and excellent biocompatibility, but also can achieve intelligent responsive drug release through surface functionalization, including multiple modes such as pH-sensitive, photothermal triggered, and magnetic targeting. Innovative fictionization strategies such as folate receptor-mediated active targeting, PEGylation, and stimulus-responsive polymer coating have enabled BN nanocarriers to overcome critical issues associated with traditional drug delivery systems such as poor targeting efficiency and significant toxicity. Particularly in tumor therapy, BN-based drug delivery systems have demonstrated dual advantages: they can not only significantly enhance the drug accumulation at the lesion sites, but also enable controlled release triggered by the tumor microenvironment, providing new ideas for breaking through therapeutic bottlenecks such as the blood-brain barrier. Although BN nanomaterials have achieved significant progress in drug loading capacity, targeting and biosafety, their clinical application still faces challenges such as large-scale manufacturing and long-term toxicological evaluation. Future research should focus on developing multifunctional integrated BN vectors, exploring their applications in emerging fields such as gene therapy and immunomodulation. These efforts will promote the development of nanomedicine towards greater precision and intelligence, with the expectation of providing innovative solutions for tumor treatment and opening up a brand-new path for the design of next generation drug delivery systems.

Abstract: Diabetes is a chronic metabolic disorder and a leading cause of death and disability worldwide, posing a serious threat to human health. Approximately 90% of diabetes is type 2 diabetes mellitus (T2DM), primarily caused by insulin resistance or abnormal insulin secretion. The hallmark of T2DM is persistent hyperglycemia, and poor long-term glycemic control can further lead to various complications such as nephropathy, cardiovascular disease, obesity, blindness, and hypertension. These complications significantly reduce the quality of patients’ life and are major contributors to disability and mortality of diabetic patients. Carbazole derivatives, an important class of nitrogen-containing heterocyclic compounds, has attracted widespread attention in medicinal chemistry due to their diverse biological and pharmacological properties, such as antibacterial, anticancer, antioxidant, and anti-inflammatory effects. In recent years, carbazole compounds have shown great potential in antidiabetes drug research and development. Research worldwide have designed and synthesized numerous small molecules with antidiabetes activity based on the carbazole scaffold. This review summarized recent natural and synthetic carbazole derivatives with antidiabetic activity, focusing on key therapeutic targets such as α-glucosidase, α-amylase, peroxisome proliferator activated receptors (PPARs) and protein tyrosine phosphatase 1B (PTP1B). The aim is to provide reference for the subsequent development of novel antidiabetes agents.

摘要:力达霉素是我国从土壤中筛选出的一个新的烯二炔类抗肿瘤抗生素,以力达霉素(LDP-AE)为基础,制备的重组融合蛋白(LDP-D3、Fv-LDP、Fv-LDP-D3)及其抗体偶联药物(LDP-D3-AE、Fv-LDP-AE、Fv-LDP-D3-AE)具有良好的抗肿瘤活性,但其相关蛋白结构尚未解析,所合成的抗体偶联药物结构是否稳定也尚未验证。基于以上研究背景,采用AlphaFold3对Fv-LDP、LDP-D3、Fv-LDP-D3重组融合蛋白的三级折叠结构进行预测,将LDP及3种重组融合蛋白分别与AE对接得到LDP-AE、LDP-D3-AE、Fv-LDP-AE和Fv-LDP-D3-AE 4种复合物,通过动力学模拟及结合自由能计算分析了4种复合物结构的稳定性,其中Fv是抗EGFR单链可变区片段,D3是人血清白蛋白(HSA)的结构域Ⅲ,LDP是力达霉素(LDM)的辅基蛋白,AE是LDM的活性烯二炔发色团。分子对接结果显示4种蛋白质均能与AE形成稳定结构,且均结合在LDP片段部分。采用多种方法对动力学模拟结果进行深入分析探讨,不同的分析方法之间可以相互印证,结果表明LDP、LDP-D3、Fv-LDP和Fv-LDP-D3均能与AE形成结构稳定的复合物,其中范德华力在这4个复合物形成的过程中起着重要作用,氢键作用也有相当一部分的贡献。

Computational Analysis of Structural Stability for Recombinant Fusion Protein-based Antibody-Drug Conjugates Derived from Lidamycin LIU Meng-ting, GUO Yi-han, MENG Zi, LIU Si-yu, HAN Tian-chao, ZHAO Wen-bo* (School of Chemistry and Chemical Engineering, Zhengzhou Normal University, Zhengzhou 450000,China)
Abstract: Lidamycin is a novel enediyne-class antitumor antibiotic isolated from soil samples in China. The recombinant fusion proteins (LDP-D3, Fv-LDP, Fv-LDP-D3) and their antibody-conjugated drugs (LDP-D3-AE, Fv-LDP-AE, Fv-LDP-D3-AE) ,constructed based on lidamycin (LDP-AE), have demonstrated potent anti-tumor activity. However, the structural information of these protein remain unsolved, and the stability of the synthesized antibody?drug conjugates has yet to be confirmed. To address this gap, AlphaFold3 was utilized to predict the tertiary folding structures of the recombinant fusion proteins Fv-LDP, LDP-D3, and Fv-LDP-D3. These proteins were then docked with AE, yielding four complexes: LDP-AE, LDP-D3-AE, Fv-LDP-AE, and Fv-LDP-D3-AE. The structural stability of these four complexes was analyzed through molecular dynamics simulations and binding free energy calculations. Specifically, Fv represented the single-chain variable fragment (scFv) of anti-EGFR, D3 was domain III of human serum albumin (HSA), LDP was the ligand-binding protein of lidamycin (LDM), and AE refered to the active enediyne chromophore of LDM. Molecular docking results revealed that all four proteins form stable structures with AE, with binding occurring specifically within the LDP fragment regions. Multiple analytical methods were applied to further analyze the molecular dynamics simulation results, and the results corroborated each other. The results demonstrate that LDP, LDP-D3, Fv-LDP, and Fv-LDP-D3 can all form structurally stable complexes with AE with Van der Waals forces playing a crucial role in complexes formation and hydrogen bonding providing additional stability.

Synthesis and Application of Cu (II) and Zn (II) Ionic Fluorescent Probes with AIE Properties LIU Jie*, TIAN Wen-hui, ZHU Xue-yu, LI Hui, LI Zi-kang, LIU Xi, ZHANG Feng-xiang (School of Chemistry and Materials Engineering, Fuyang Normal University, Fuyang 236037, China)
Abstract: Target compound 7-diethylamino-3-formylcoumarin (2 '- thienoyl) hydrazone (L) was synthesized from 4-diethylaminosalicylaldehyde and diethyl malonate through Knoevenagel condensation cyclization (intermediate I), hydrolytic decarboxylation (intermediate II), Vilsmeier reaction (intermediate III), and nucleophilic addition reaction. The structure was characterized by nuclear magnetic resonance spectroscopy (1H-NMR, 13C-NMR). Based on the study of its UV spectrum, fluorescence spectrum, and aggregation induced emission (AIE), its ion recognition applications were explored. The results showed that in tetrahydrofuran solution, probe L selectively quenched fluorescence for Cu2+and displayed a ratio type fluorescence recognition for Zn2+, demonstrating precise ion recognition ability and good detection sensitivity. It was less affected by interference from other ions, with significant color changes before and after the reaction (fluorescence quenching occurred upon adding copper ions under 365 nm UV light; the color changed from green to yellow upon adding zinc ions). The Job’s curve showed that the stoichiometric ratios of probe L to Cu2+ and Zn2+ were 1:1 and 2:1, respectively, with binding constants Kb of 5.18×105 and 1.51×106 L/mol. The detection limits were 5.52×10-7 and 1.13×10-6 mol/L, respectively, which are both lower than the maximum allowable concentrations of Cu2+and Zn2+in drinking water as per the World Health Organization. The experimental results indicate that the fluorescent probe has potential application in environmental monitoring and is expected to be used for the detection of Cu2+and Zn2+in food and water environments.

摘要:亚硝酸盐作为环境与食品中常见污染物,其快速灵敏检测对公共健康保障具有重要意义。研究基于罗丹明800与羟胺开发了一种新型水溶性荧光探针Rh-PAO,其偕胺肟结构在强酸性条件下与亚硝酸盐(NO2⁻)通过重氮化反应生成NO+,导致探针红色荧光快速猝灭,并伴随溶液颜色由蓝色变为无色。该反应可在5 min内完成,且探针在50倍浓度共存离子(如Fe3+、NO3⁻等)存在下仍保持高选择性,抗干扰能力显著。基于荧光光谱与紫外-可见吸收光谱的双模检测方法,Rh-PAO对亚硝酸盐的检出限分别达9.7×10-8和8.6×10-8 mol/L,灵敏度较传统Griess比色法(检出限~10-7 mol/L)及苯二胺类探针提升2~3个数量级。该方法成功应用于瓶装水与湖水样本中亚硝酸盐的检测,加标回收率为97.4%~112.9%,相对标准偏差(RSD)低于3.87%。研究进一步结合小型加热装置构建便携式检测系统,可在现场实现亚硝酸盐的可视化快速分析。通过偕胺肟反应位点的设计策略,探针的重氮化反应速率与水溶性显著提升,解决了传统苯二胺结构反应速度慢、水溶性差的缺陷。工作为亚硝酸盐的高效检测提供了新方法,在环境水质监测与食品安全领域展现出重要应用潜力。

Abstract: Nitrite, a common contaminant in both environmental and food samples, poses a significant threat to public health. Therefore, its rapid and sensitive detection is of great importance. In this study, a novel water-soluble fluorescent probe, Rh-PAO, was developed based on rhodamine 800 and hydroxylamine. The amidoxime moiety of the probe undergoes diazotization with nitrite (NO₃⁻) under strongly acidic conditions to produce NO⁺, resulting in a rapid quenching of the red fluorescence and a distinct color change of the solution from blue to colorless. This reaction was completed within 5 minutes. The probe exhibits high selectivity and anti-interference capability, maintaining high specificity even in the presence of 50-fold concentrations of coexisting ions (e.g., Fe³⁺, NO₃⁻, etc.). demonstrating remarkable immunity to interference. A dual-mode detection strategy using both fluorescence and UV-visible absorption spectroscopy was established. The detection limits of nitrite was 9.7×10−8 and 8.6×10−8 mol/L, respectively, representing a 2~3 order of magnitude improvement in sensitivity compared to the traditional Griess colorimetric method (detection limit ~10−7 mol/L) and the phenylenediamine-based probe. This method was successfully used to determine nitrite levels in bottled and lake water samples, achieving recoveries ranging from 97.4% to 112.9% and relative standard deviations (RSDs) below 3.87%. Furthermore, a portable detection system was constructed by integrating a miniaturized heating device, enabling on-site and visual detection of nitrite. The design strategy for the amidoxime reactive site significantly enhanced the diazotization reaction rate and water solubility of the probe, overcoming the limitations of the traditional phenylenediamine-based probes in terms of slow response and poor aqueous solubility. This work provides a new, efficient method for detecting nitrite and has important potential applications in environmental water quality monitoring and food safety.

摘要:以蔗糖为碳源,磷酸二氢铵为氮与磷源,通过一步水热法制备了一种耐酸型氮、磷掺杂碳量子点(ART-N,P-CQDs)作荧光探针,利用透射电镜(TEM)、傅里叶红外光谱(FT-IR)、纳米粒度分析仪、X-射线光电子能谱(XPS)、紫外分光光度计和荧光分光光度计对ART-N,P-CQDs的结构及其光学性质进行表征分析。结果显示,ART-N,P-CQDs为平均粒径1.7 nm的球形结构,其表面含有丰富的羟基、羧基、胺基、磷酸酯基等丰富的含氮、磷、氧的官能团,具有激发独立性的蓝色荧光,荧光量子产率为4.7%。鉴于Fe(Ⅲ)对ART-N,P-CQDs具有荧光猝灭效应,且为了准确检测Fe(Ⅲ),需将其置于酸性环境以防止三价铁水解。从而构建了一种能在酸性环境下检测微量Fe(Ⅲ)的新方法。该方法线性方程为F0/F=0.00364c(Fe3+)+0.9901(R2=0.9942),检出限为1.49 μmol/L,线性范围为10~100 μmol/L,能量转移猝灭和静态猝灭过程是致使ART-N,P-CQDs荧光猝灭的原因。ART-N,P-CQDs在一定酸性环境、离子强度及干扰离子共存的条件下检测体系仍具有良好的荧光稳定性,将该方法应用于补铁药品中微量铁的测定,其加标回收率为94.59%~99.53%,结果令人满意。该方法操作简便,可用于市面上补铁药片中铁含量的检测,具有一定的应用前景。

Abstract:Using sucrose as carbon source and ammonium dihydrogen phosphate as nitrogen and phosphorus sources, acid-resistance type nitrogen and phosphorus doped carbon quantum dots (ART-N,P-CQDs) were synthesized by a one-step hydrothermal method and applied as fluorescent probes. The structure and optical properties of ART-N, P-CQDs were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), nanoparticle size analyzer, X-ray photoelectron spectroscopy (XPS), UV-visible absorption spectrum and fluorescence spectrophotometer. The results showed that ART-N,P-CQDs had a spherical structure with an average particle size of 1.7 nm, and their surfaces were rich in functional groups such as hydroxyl, carboxyl, amine, phosphate containing nitrogen, phosphorus and oxygen atoms. The quantum dots exhibits bright blue fluorescence with excitation independence and a fluorescence quantum yield of 4.7%. Considering the fluorescence quenching effect of Fe(III) and the need for accurate detection in acidic environments to prevent hydrolysis, a new method was developed for detecting trace amounts of Fe(III) under acidic conditions. The linear relationship was given by the equation : F0/F=0.00364c(Fe3+)+0.9901 (R2=0.9942), with a limit of detection of 1.49 μmol/L and a linear range of 10 ~ 100 μmol/L. The fluorescence quenching mechanism was attributed to energy transfer quenching and static quenching. The detection system maintained good fluorescence stability under acidic conditions, varying ionic strength, and coexistence of interfering ions. The method was successfully applied to the determination of trace iron in commercial iron supplementation, yielding spiked recoveries of 94.59% to 99.53% with satisfactory results. Owing to its operational simplicity and reliability, the proposed method demonstrates promising potential for iron quantification in commercially iron supplements.

Research Progress of Lignin-Cellulose Multifunctional Composites LI Mei-chan, LI He, LI Can, FU Yong-sheng, LI Jun, LI De-qiang* (College of Chemistry and Chemical Engineering, Xinjiang Agricultural University, Urumqi 830052, China)
Abstract:In recent years, the growing awareness of environmental protection and the advancement of sustainable development strategies have propelled the development of environmentally friendly bio-based materials as alternatives to traditional petroleum-derived plastics, making this a major research focus in materials science. Cellulose, the most abundant biomass resource in nature, exhibits remarkable film-forming properties, renewability, and biodegradability owing to the high density of hydroxyl groups along its molecular chain. Nevertheless, its limitations in ultraviolet shielding, flame retardancy, and antioxidant properties hinder broader applications in high-value field. In this context, lignin has garnered substantial attention due to its distinctive molecular structure. The aromatic ring structures and diverse reactive functional groups inherent in lignin molecules provide remarkable thermal stability, antioxidant capacity, and superior ultraviolet shielding performance. These characteristics enable lignin to effectively expand the application scope of cellulose, while maintaining its biodegradability. Based on the current research status, this paper systematically reviews the latest advancements in lignin-cellulose composite materials, with an emphasis on elucidating the mechanisms by which lignin influences key properties such as flame retardancy, UV resistance, antioxidant capacity, and antibacterial activity of cellulose-based materials. Furthermore, this paper also addressed the major challenges and opportunities in this field, offering valuable insights for the development of next-generation multifunctional bio-based functional materials.

Abstract: This study aims to optimize the parameters for ultra-speed crushing-assisted extraction of lutein esters from marigold flowers using response surface methodology, and to evaluate the anticancer bioactivity of the resulting extract. Based on single-factor experiments, three critical parameters: number of extraction cycles, extraction time, and solid-to-liquid ratio, were selected for process optimization, with lutein esters yield as the evaluation metric, Additionally, lutein esters solutions at concentrations of 20, 40, and 80 µg/mL were tested to assess their effects on HeLa cell viability by CCK-8 assay and apoptosis by FITC-Annexin V/PI flow cytometry. The optimal extraction conditions were determined as follows: rotational speed of 3500 r/min, 3 extraction cycles, 9 min of extraction time, and a solid-to-liquid ratio of 1:19 (g/mL), achieving a lutein esters extraction yield of 15.66%. Cell viability was measured by CCK-8 kit, and the apoptosis rate was detected by FITC-Annexin V/PI flow cytometry. Experimental results demonstrated dose-dependent inhibitory effects of lutein esters on HeLa cell proliferation; with the increase of lutein esters concentration, the inhibitory effect was enhanced. At 80 µg/mL, lutein esters reduced HeLa cell viability by approximately 50%. The ultra-speed crushing-assisted extraction method enables efficient and low-cost extraction of lutein esters from marigold flowers, providing a viable strategy for industrial-scale production. Furthermore, the lutein esters extract exhibits potent inhibitory activity against HeLa cell growth, highlighting its potential as a natural anticancer agent.

摘要:针对传统检测方法在复杂基质中分离效率不足的问题,首次将响应面法(RSM)与高效液相色谱-电感耦合等离子体质谱(HPLC-ICP-MS)联用技术结合,建立了一种高灵敏度环境地表水中砷酸盐(As(V))、亚砷酸盐(As(III))、一甲基砷(MMA)、二甲基砷(DMA)、砷甜菜碱(AsB)、砷胆碱(AsC)6种形态砷的分析方法。通过Box-Behnken设计优化流动相pH(6.0 ~7.0)、甲醇比例(10% ~ 20%)及进样量(20~40 μL),成功的构建了二次回归模型(RAdj2=0.951),利用响应面法优化得出最优条件,研究发现pH与甲醇交互作用显著影响分离效率,最优条件为pH 6.7、甲醇13%、进样量28 μL,总分离度达11.4±0.3。采用Hamilton PRP-X100色谱柱与梯度洗脱程序,6种形态砷(As(III)、As(V)、MMA、DMA、AsB、AsC)均能在12 min内实现基线分离(分离度>1.5),各形态砷检出限为0.06 ~ 0.17 μg/L,加标回收为95.4%~104.7%,相对标准偏差<6%。运用于实际水样分析显示,无机砷As(III)和As(V)占到总砷的60%~80%,是水中砷的主要存在形态。通过碰撞反应池技术能够有效消除40Ar35Cl+干扰,建立的校正方程(I校正=I实测−0.13I干扰)显著提升检测准确性。

Analysis of Arsenic Species in Environmental Surface Water for RSM by High-Performance Liquid Chromatography-Inductively Coupled Plasma Mass Spectrometry NIU Qian*,ZHANG Jun-wei (Luoyang Ecological & Environmental Monitoring Center, Luoyang 471000, China)
Abstract: To address the insufficient separation efficiency of traditional detection methods in complex matrices, a novel method was developed by integration response surface methodology (RSM) with high-performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) for the sensitive determination of six arsenic species in environmental surface water: arsenate (As(V)), arsenite (As(III)), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), arsenobetaine (AsB), and arsenocholine (AsC). A Box-Behnken design was employed to optimize the mobile phase pH (6.0~7.0), methanol ratio (10%~20%), and injection volume (20~40 μL), resulting in a well-fitted quadratic regression model (R² = 0.951). Significant interaction between pH and methanol was observed. The optimal conditions were determined to be pH 6.7, 13% methanol and 28 μL injection, yielding a total resolution of (11.4 ±0.3). Using a Hamilton PRP-X100 column with gradient elution, all six arsenic species were baseline separated (resolution>1.5) within 12 minutes. Detection limits ranged from 0.06 to 0.17 μg/L, with spike recoveries of 95.4% to 104.7% and relative standard deviations below 6%. Field analysis revealed inorganic arsenic species (As(III)+As(V)) accounted for 60%-80% of total arsenic. Interference from 40Ar35Cl+ was effectively eliminated using collision/reaction cell technology (He flow 4.5 mL/min), and a correction equation (Icorrected = Imeasured - 0.13Iinterference) significantly enhanced detection accuracy.

Application of ELISA Rapid Test Technology in Synthetic Colorants Detection LIANG Rui-dan, MA Kang*, ZHOU Shu-kun (National Institute of Metrology, Beijing 100029, China)
Abstract:As food safety increasingly becomes a focus of public concern, the use of food additives, especially synthetic colorants, has become an important issue. Synthetic colorants may not only enhance the visual appeal of food, but also have potential hazards to human health, such as allergic reactions and carcinogenicity. Therefore, the development of highly efficient, sensitive, and rapid test technologies is crucial for food safety. Enzyme-linked immunosorbent assay (ELISA) leverages the specific binding between antigens and antibodies to efficiently and accurately identify and quantify trace amounts of synthetic colorants in food. Compared with traditional detection methods, ELISA significantly improves the efficiency of on-site food safety inspections. This review summarized the current application status of ELISA in synthetic colorant detection, and analyzed its advantages and limitations in the detection of different types of colorants. The successful application of ELISA in detecting azo, triylmethane and oxanthene dyes was discussed, and the challenges of ELISA in multiplex detection capability, sample matrix effect, and operational complexity were highlighted. Finally, the future development direction of ELISA for food synthetic colorants was prospected, and the importance of technological innovation and optimization in enhancing food safety testing, protecting public health, and improving food quality assurance was emphasized.

ABSTRACT: A rapid and efficient pre-treatment was established for determining six ginsenosides (Rb1, Rb2, Rc, Rd, Re and Rg1) in three types of ginseng-containing imported available on the market: emulsions, creams, and facial masks. Qualitative and quantitative analyses of these ginsenosides was carried out using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The developed method was optimized mainly in terms of chromatographic and mass spectrometric conditions to improve the detection sensitivity and accuracy. Samples were extracted by ultrasonic ethanol-water method. The extracted was purified by C18 solid-phase extraction column and reconstituted after nitrogen evaporation. Detection was performed using HPLC-MS/MS with acetonitrile-0.1% formic acid aqueous solution as the mobile phase, under multiple reaction monitoring (MRM) mode and negative ion scanning. After method verification, the six ginsenosides showed good linearity in the concentration range of 0.2 ~100 μg/L (R>0.9995). The detection limit of the method was 0.01~0.06 μg/kg, and the quantification limit was 0.02~0.5 μg/kg, which meets the measurement requirements. Thirty-three blank samples were each spiked at three concentration levels (5, 10, 20 μg/kg, n=6). The relative standard deviations were all below 5% and the spiked recovery rates were all above 80%. This method is used for qualitative and quantitative analysis of six ginsenosides in imported ginseng cosmetics, which offers high sensitivity, good repeatability, high accuracy, and precision. This method can provide assessment data and technical support for the customs supervision for imported ginseng cosmetics.

Abstract:Cinnoline, a class of diazaheterocyclic compounds fused by benzene ring and pyridazine ring, has become an important research object in synthetic chemistry, drug development, and functional materials due to its unique rigid planar structure and notable biological activity. The conjugation between the benzene and heterocyclic rings, combined with substituent effects and energy level modulation, can significantly regulate the electron density distribution. This electronic structure modulates its biological activities (antibacterial, anticancer), photoelectric properties (luminescence efficacy), and chemical reactivity (C?H activation selectivity). Recent studies have demostrated cinnoline derivatives showed promising pharmacological activities , including antibacterial, analgesic, anti-inflammatory, anti-tumor effects. However, the development of efficient synthetic routes for these complex fused ring conjugated systems remains a major challenge in synthetic chemistry. The article categorized cinnoline synthesis strategies based on the chemical characteristics of the starting materials and their corresponding synthetic precursors, including azobenzene/triazole, aryl hydrazine/aroyl hydrazone, and aryl pyrazolone/indazolone. This study systematically summarized advanced strategies for constructing cinnoline fused-ring systems, aiming to provide theoretical basis and methodological references for the in-depth research and application development. Finally, the future application of fused cinnoline compoinds in drug development and functional material were discussed. The current challenges were anayzed, and the corresponding solutions were proposed.

Synthesis of Nitrogen-Containing Spiro Aromatic Ketones ZHANG Lin-Jie 1,LUO Qiang1,KE De-hong2,XU Sheng*1 (1. School of Chemistry and Molecular Engineering,East China University of Science and Technology,Shanghai 200237,China; 2. Shanghai Our ChemBio-Technology Co., Ltd., Shanghai 201506, China)
Abstract:α-Azaspiro rings are a class of important organic ligands, because of the nucleophilic nitrogen atoms and the unique spatial structure of these compounds, often used as organic ligands for spirochiral metal-organic compounds. Actually, they are important intermediates in the synthesis of drugs. On the other hand, carbonyl is a potential organic functional group conversion precursor that can be converted into organic ligands with potential coordination functions through nucleophilic addition reactions, such as Schiff bases, oximes, hydrazones, and semicarbazides obtained by reacting with H2NG, and α - hydroxynitriles obtained by adding with HCN, reaction with cyclopentadienyl metal salt to obtain fulvene, which then serves as a metallocene ligand, etc. Carbonyl and amino groups at the α, α '- positions of the spiro atom were introduced to form nitrogen-containing spirocyclic aromatic ketone compounds, which serve as chiral spiro ligands and provide important technical support for the synthesis of spiro chiral catalysts. Aromatic ketones was used as raw materials, a series of novel nitrogen-containing spirocyclic aromatic ketone compounds were obtained in high yield through four steps of oxime introduction, reduction, cyclization, and deacetylation. All these products were well characterized by 1HNMR, 13CNMR, and HRMS to confirm their structures. The spatial structure of P5 was confirmed by single-crystal X-ray diffraction, and the nitrogen-containing heterocycles were spatially distorted irregular pentagons influenced by nitrogen atoms. The research results indicate that the method proposed in this article has the advantages of simple process, high product yield, and thermal stability of the product.
