A series of novel anthranilic diamides containing N-substituted arylmethyl moieties was designed and synthesized, in which the bond distance and conjugation pattern between pyrazole and pyridine rings contained in Chlorantraniliprole were changed. Their structures were confirmed by JH NMR, IR, elemental analysis or high resolution mass spectromentry{HRMS）, and the conformation of compound 4d was confirmed by X-ray diffraction. The preliminary bioassay results indicate that all the target compounds exhibited moderate insecticidal activity against oriental armyworm at 200 mg/L and some of them presented favorable antitumor activities against human lung cancer cells（A549）, liver cancer cells（BelT402） and colon cancer celis（HCT-8） in vitro by microculture tetrazolium（MTT） method, among which compound 6j afforded the best anti-proliferative activity at 5μg/mL.

In search of environmentally benign insecticides with high activity, low toxicity and low residue, a series of novel anthranilic diamide derivatives containing N-pyridylpyrazole was designed and synthesized. All the compounds were characterized by H NMR spectroscopy and elemental analysis. The single crystal structure of com pound 8j was determined by X-ray diffraction. The insecticidal activities of the new compounds were evaluated. The results show that some compounds exhibited moderate insecticidal activities against Lepidoptera pests. Among this series of compounds, compounds 80 and 8p showed 100% larvicidal activity against Mythimna separate Walker, Plutella xylostella linnaeus and Laphygma exigua Hubner at a test concentration of 200 mg/kg, which is equal to the commercial chlorantraniliprole.

Thirteen novel phenyl substituted isoxazolecarboxamides were synthesized, and their structures were characterized by IH NMR, elementary analysis and high-resolution mass spectrometry（HRMS） techniques. Their evaluated insecticidal activities against oriental armyworm（Mythimna separata） indicate that the phenyl substituted isoxazolecarboxamides exhibited moderate insecticidal activities, among which compounds 9c and 9k showed com- paratively higher activities.

A series of novel anthranilic diamides analogues containing benzo[b]thiophenyl ring was designed and synthesized. Their structures were characterized by melting points, 1H nuclear magnetic resonance（IH NMR） and high-resolution mass spectrometry（HRMS）. The bioassay tests indicate that their insecticidal activities were weak to moderate. Antibacterial tests indicate that some of the compounds showed favourable activity in vitro against Physa- lospora piricola, Alternaria solani, Cercospora arachidicola, Gibberella sanbinetti and Phytophthora infestans at a dosage of 50 mg/L.

In search of environmentally benign insecticides with high activity, low toxicity and low resistance, a series of novel anthranilic（isophthalic） acid esters was designed and synthesized based on the structure of ryanodine modulating agent. All the compounds were characterized by 1H NMR spectra, elemental analysis or high resolution mass spectrometry（HRMS）. The preliminary results of biological activity assessment indicate that some of the title compounds exhibit certain but unremarkable insecticidal activity against Mythimna separata Walker at 200 mg/L and fungicidal activities against five funguses at 50 mg/L.

IL-13主要是由活化T 细胞产生的12 kD 的多效性细胞因子。IL-13和IL-4蛋白在氨基酸序列上有30％的同一性［1］，前者可在B 淋巴细胞、内皮细胞、单核细胞等诸多细胞中通过由IL-4Rα、IL-13Rα1和IL-13Rα2组成的复杂受体系统发挥效应。IL-13Rα1单独和IL-13结合能力很弱，但与IL-4Rα形成异源二聚体后却可形成高亲和力的IL-13受体复合物，并激活Janus 蛋白激酶／信号转导子及转录激活子（Janus kinase ／signal transducers and activators oftranscription， JAK／STAT）信号通路发挥功能。目前已证实IL-13与多种疾病如肿瘤、纤维化密切相关［2］。IL-13Rα2比IL-13Rα1更易与IL-13结合，所以它能与IL-13Rα1竞争IL-13并阻断JAK／STAT 通路介导的纤维化过程，又由于胞浆尾很短而被视为诱饵受体＂。最近研究［3］表明在相关模型中其可以通过AP-1／TGF-β等通路发挥信号功能并最终导致纤维化。此外，IL-13Rα2在肿瘤细胞中高表达，因此，很有可能以IL-13Rα2为特异性的靶向受体来探索肿瘤治疗新方法。

In this study, we present a unified sparsity-driven framework that significantly enhances motion deblurring performance by integrating two key components: a custom-designed dataset and a low-rank module(LRM). This framework leverages the inherent sparsity of per-pixel blur kernels to bolster both deblurring accuracy and model interpretability. Firstly, we propose an adaptive-basis decomposition-based deblurring(ADD) approach, which constructs a tailored training dataset to enhance the generalization capacity of the deblurring network. The ADD framework adaptively decomposes motion blur into sparse basis elements, effectively addressing the intricacies associated with non-uniform blurs. Secondly, an LRM is proposed to improve the interpretability of deblurring models as a plug-and-play module, primarily designed to identify and harness the intrinsic sparse features in sharp images. A series of ablation studies have been conducted to substantiate the synergistic advantages of combining the proposed ADD with the LRM for overall improvement in deblurring efficacy. Subsequently, we empirically demonstrate through rigorous experimentation that incorporating the LRM into an existing Uformer network leads to substantial enhancement in reconstruction performance. This integration yields a sparsity-guided low-rank network(SGLRN). Operating under the overarching principle of sparsity, SGLRN consistently outperforms state-of-the-art methods across multiple standard deblurring benchmarks. Comprehensive experimental results, assessed through quantitative metrics and qualitative visual evaluations, provide compelling evidence of its effectiveness. The overall deblurring results are available at Google Drive.
