2Development of the triazole-fused pyrimidine derivatives as highly potent and reversible inhibitors of histone lysine specific demethylase1(LSD1/KDM1A)显示文摘Histone lysine specific demethylase 1(LSD1) has been recognized as an important modulator in post-translational process in epigenetics. Dysregulation of LSD1 has been implicated in the development of various cancers. Herein, we report the discovery of the hit compound 8 a(IC50=3.93 μmol/L) and further medicinal chemistry efforts, leading to the generation of compound 15 u(IC50=49 nmol/L, and Ki= 16 nmol/L), which inhibited LSD1 reversibly and competitively with H3 K4 me2, and was selective to LSD1 over MAO-A/B. Docking studies were performed to rationalize the potency ofcompound 15 u. Compound 15 u also showed strong antiproliferative activity against four leukemia cell lines(OCL-AML3, K562, THP-1 and U937) as well as the lymphoma cell line Raji with the IC50 values of 1.79, 1.30, 0.45, 1.22 and 1.40 μmol/L, respectively. In THP-1 cell line, 15 u significantly inhibited colony formation and caused remarkable morphological changes. Compound 15 u induced expression of CD86 and CD11 b in THP-1 cells, confirming its cellular activity and ability of inducing differentiation.The findings further indicate that targeting LSD1 is a promising strategy for AML treatment, the triazolefused pyrimidine derivatives are new scaffolds for the development of LSD1/KDM1 A inhibitors.Zhonghua Li Lina Ding Zhongrui Li Zhizheng Wang Fengzhi Suo Dandan Shen Taoqian Zhao Xudong Sun Junwei Wang Ying Liu Liying Ma Bing Zhao Pengfei Geng Bin Yu Yichao Zheng Hongmin Liu 2019Acta Pharmaceutica Sinica B2019,9,4:6
3Elastin-like polypeptide modified silk fibroin porous scaffold promotes osteochondral repair显示文摘Silk fibroin(SF)is considered biocompatible and biodegradable for osteochondral repair.However,it lacks a bioactive domain for cell adhesion,proliferation and differentiation,limiting its therapeutic efficacy.To revamp SF as a biomimicking and bioactive microenvironment to regulate cell behaviours,we engineered an elastin-like polypeptide(ELP,Val-Pro-Gly-Xaa-Gly)to modify SF fibers via simple and green dehydrothermal(DHT)treatment.Our results demonstrated that the ELP successfully bound to SF,and the scaffold was reinforced by the fusion of the silk fiber intersections with ELP(S-ELP-DHT)via the DHT treatment.Both bone mesenchymal stem cells(BMSCs)and chondrocytes exhibited improved spreading and proliferation on the S-ELP-DHT scaffolds.The ex vivo and in vivo experiments further demonstrated enhanced mature bone and cartilage tissue formation using the S-ELP-DHT scaffolds compared to the naked SF scaffolds.These results indicated that a recombinant ELPmodified silk scaffold can mimic three-dimensional(3D)cell microenvironment,and improve bone and cartilage regeneration.We envision that our scaffolds have huge clinical potential for osteochondral repair.Zhuoyue Chen Qiang Zhang Hongmin Li Qi Wei Xin Zhao Fulin Chen 2021Bioactive Materials2021,6,3:4

5POLICIES AND REGULATIONS FOR PROMOTING MANURE MANAGEMENT FOR SUSTAINABLE LIVESTOCK PRODUCTION IN CHINA:A REVIEW显示文摘Livestock numbers in China have more than tripled between 1980 and 2017.The increase in the number of intensive livestock production systems has created the challenges of decoupled crop and livestock systems,low utilization of manures in croplands,and subsequent environmental pollution.Correspondingly,the government has enacted a series of policies and regulations to increase the sustainability of livestock production.This paper reviews the objectives of these policies and regulations and their impacts on manure management.Since 2017 there have been two policy guides to speed up the appropriate use of manures,three action plans for increasing manure recycling,and one technical guide to calculate nutrient balances.Requirements of manure pollution control and recycling for improved environmental performance of livestock production systems were included in three revised environmental laws.Most recent survey data indicate that the utilization of livestock manures was 70%in 2017,including that used as fertilizer and/or for production of energy.The targets for manure utilization are 75%in 2020 and 90%in 2035.To achieve these targets and promote‘green livestock production’,additional changes are needed including the use of third-party enterprises that facilitate manure exchange between farms and a more integrated manure nutrient management approach.Sha WEI Zhiping ZHU Jing ZHAO David RCHADWICK Hongmin DONG 2021Frontiers of Agricultural Science and Engineering2021,8,1:2
6The Active Sites and Corresponding Stability Challenges of the M-N-C Catalysts for Proton Exchange Membrane Fuel Cell显示文摘Proton exchange membrane fuel cells(PEMFCs)as promising alternatives to traditional internal combustion engines have attracted massive concerns to promote their wide application in society.However,the biggest challenge to the commercialization of PEMFCs remains the high cost due to the adoption of the platinum group metal(PGM)catalysts in the cathode.Ruolin Peng Zhongkun Zhao Hongmin Sun Yongping Yang Tinglu Song Yao Yang Jiankun Shao Haibo Jin Hongtao Sun Zipeng Zhao 2023Chinese Journal of Chemistry2023,41,6:1

9BrΦnsted acid-promoted ‘on-water’ C(sp^3)-H functionalization fot the synthesis of isoindolinone/[1,2,4]triazolo[1,5-a]pyrimidine derivatives targeting the SKP2-CKS1 interaction显示文摘The isoindolinone and biaryl scaffolds are prevalent in natural products and drug molecules,which have showed broad and interesting biological activities.The efficient construction of such hybridized molecules and biological evaluation are of great interest to medicinal chemistry community.In this communication,we report an efficient BrΦnsted acid-promoted C(sp^3)-H functionalization approach that enables the rapid construction of biologically important isoindolinone/[1,2,4]triazolo[1,5-a]pyrimidine hybrids from 5-methyl-7-(2,4,6-trimethoxyphenyl)-[1,2,4]triazolo[1,5-a]pyrimidine,2-formylbenzoic acid and various anilines.The title compounds were generated in high to excellent yields(up to 96%)regardless of the electronic nature and steric effects of the substituents.In this reaction,an isoindolinone scaffold,one C-C single bond,and two C-N bonds were formed simultaneously with high atom economy.In this work,we have envisioned that the methyl group linked to the electron-deficient Nheterocycles could be used as a new synthetic handle for late-state diversification and may have broad applications in the field of organic and medicinal chemistry.Besides,the title compounds have exhibited promising activity against the SKP2-CKS1 interaction.Shuo Yuan Sixi Wang Min Zhao Danqing Zhang Jinjie Chen Jian-Xin Li Jingya Zhang Yihui Song Jinyi Wang Bin Yu Hongmin Liu 2020Chinese Chemical Letters2020,31,2:1

12Effect of aspirin alone or combined with cisplatin on human cervical carcinoma HeLa cells显示文摘Objective: To study the effect and mechanism of aspirin alone or combined with cisplatin(DDP)on human cervical carcinoma HeLa cells. Methods: HeLa cells were treated by different concentrations of aspirin, DDP alone or both. The inhibitory effect on cell growth was analyzed by MTT and colony-forming assay. Cell apoptosis was measured with flow cytometry. The mRNA levels of Bcl-2, Bax and NF-κB(P65) were studied by RT-PCR. Results: MTT assay showed that aspirin inhibited HeLa cell proliferation in a time- and dose-dependant manner. Aspirin decreased clone numbers in colony formation assay. Aspirin also induced apoptosis of HeLa cells in a dose- and time-dependent manner as detected by flow cytometry. The inhibition effects on proliferation, colony formation and apoptosis were significantly enhanced when cells were treated with both aspirin and DDP. RT-PCR demonstrated that aspirin decreased the transcription of Bcl-2 and NF-κB, and increased expression of Bax gene. Conclusion: Aspirin can induce apoptosis in HeLa cells. Combination of aspirin and DDP displays a synergistic effect. The possible mechanism might be that aspirin downregulates the mRNA levels of Bcl-2 and NF-κB gene and upregulates the expression of Bax.Wang Yueling Zhao Hongmin Liu Lin Wang Jiangfen 2010Journal of Medical Colleges of PLA(China)2010,25,1:0
13Design,Synthesis and Bioactivities Evaluation of Novel Quinazoline Analogs Containing Oxazole Units显示文摘A novel type of quinazoline derivatives,which were designed by the combination of quinazoline as the back-bone and oxazole scaffold as the substituent,have been synthesized and their biological activities were evaluated for anti-proliferative activities and EGFR inhibitory potency.Compound 12b demonstrated the most potent inhibi-tory activity(IC_(50)=0.95μmol/L for EGFR),which could be optimized as a potential EGFR inhibitor in the further study.The structures of the synthesized quinazoline analogs and all intermediates were comfirmed by 1H and 13C NMR,2D NMR spectra,IR spectra and MS spectra.Xuehui Hou Jingyu Zhang Xuan Zhao Liming Chang Ping Hu Hongmin Liu 2014Chinese Journal of Chemistry2014,32,6:0
14An in-depth investigation into the relationships between structural metrics and unit testability in object-oriented systems显示文摘There is a common belief that structural properties of classes are important factors to determine their unit testability.However,few empirical studies have been conducted to examine the actual impact of structural properties of classes.In this paper,we employ multiple linear regression(MLR) and partial least square regression(PLSR) to investigate the relationships between the metrics measuring structural properties and unit testability of a class.The investigated structural metrics cover five property dimensions,including size,cohesion,coupling,inheritance,and complexity.Our results from open-source software systems show that:(1) most structural metrics are statistically related to unit testability in an expected direction,among which size,complexity,and coupling metrics are the most important predictors;that(2) multivariate regression models based on structural metrics cannot accurately predict unit testability of classes,although they are better able to rank unit testability of classes;that(3) the transition from MLR to PLSR could significantly improve the ability to rank unit testability of classes but cannot improve the ability to predict the unit testing effort of classes.ZHOU YuMing LEUNG Haretona SONG QinBao ZHAO JianJun LU HongMin CHEN Lin XU BaoWen 2012Science China(Information Sciences)2012,55,12:0
15Mitochondrial Regulation of Macrophages in Innate Immunity and Diverse Roles of Macrophages During Cochlear Inflammation显示文摘Macrophages are essential components of the innate immune system and constitute a non-specific first line of host defense against pathogens and inflammation.Mitochondria regulate macrophage activation and innate immune responses in various inflammatory diseases,including cochlear inflammation.The distribution,number,and morphological characteristics of cochlear macrophages change significantly across different inner ear regions under various pathological conditions,including noise exposure,ototoxicity,and age-related degeneration.However,the exact mechanism underlying the role of mitochondria in macrophages in auditory function remains unclear.Here,we summarize the major factors and mitochondrial signaling pathways(e.g.,metabolism,mitochondrial reactive oxygen species,mitochondrial DNA,and the inflammasome)that influence macrophage activation in the innate immune response.In particular,we focus on the properties of cochlear macrophages,activated signaling pathways,and the secretion of inflammatory cytokines after acoustic injury.We hope this review will provide new perspectives and a basis for future research on cochlear inflammation.Yuan Zhang Fanglei Ye Xiaolong Fu Shen Li Le Wang Yutian Chen Hongmin Li Shaojuan Hao Kun Zhao Qi Feng Peipei Li 2024Neuroscience Bulletin2024,40,2:0
165G Wideband Bandpass Filtering Power Amplifiers Based on a Bandwidth-Extended Bandpass Matching Network显示文摘In this paper,a 5G wideband power amplifier(PA)with bandpass filtering response is synthesized using a bandwidth-extended bandpass filter as the matching network(MN).In this structure,the bandwidth(θ_(C))is defined as a variable in the closedform equations provided by the microstrip bandpass filter.It can be extended over a wide range only by changing the characteristic impedances of the structure.Different from the other wideband MNs,the extension of bandwidth does not increase the complexity of the structure(order n is fixed).In addition,based on the bandwidth-extended structure,the wideband design of bandpass filtering PA is not limited to the fixed bandwidth of the specific filter structure.The theoretical analysis of the MN and the design flow of the PA are provided in this design.The fabricated bandpass filtering PA can support almost one-octave bandwidth(2-3.8 GHz),covering the two 5G bands(n41 and n78).The drain efficiency of 47%-60%and output power higher than 40 dBm are measured.Good frequency selectivity in S-parameter measurements can be observed.Weimin Wang Hongmin Zhao Yongle Wu Xiaopan Chen 2023China Communications2023,20,11:0
17Cross-reactivity of anti-programmed death ligand 2 polyclonal antibody in mouse tissues显示文摘The inhibitory co-receptor programmed death 1 (PD-1, encoded by pdcd1) and its two ligands PD-L1 and PD-L2 comprise an important immune inhibitory signaling pathway for defense against microbes and for self-tolerance. Unlike other members of the B7-CD28 family, expression of PD-L1 and PD-L2 is not limited to the immune system. In this study, we determined that a polyclonal antibody (pAb) (R&D Systems) against extracellular domains of mouse PD-L2 (mPD-L2) could recognize anti- gen(s) in diverse mouse tissues, including the anterior and intermediate pituitary gland, olfactory bulbs and olfactory epitheli- um, tongue epithelium, keratinized epithelial cells and skin and whisker hair follicles. These findings differed from previous reports of mPD-L2 localization. Reverse transcription PCR and Western blot analyses, however, were unable to detect any mPD-L2 transcripts or proteins of the 25-kD predicted molecular weight in RNA and protein extracts, respectively, from the above tissues, suggesting that the anti-mPD-L2 pAb cross-reacts with certain novel antigen(s). Developmental studies revealed that the earliest expression of mPD-L2-like antigen was in the olfactory epithelium at embryonic day 12.5 (E12.5). At E14.5, mPD-L2-like antigen was present in the skin, tongue and follicles of the skin and whiskers. The distribution patterns of mPD-L2-like antigen remained similar from E18.5 to adulthood. The results of bioinformatic analysis and other experiments suggested neural cell adhesion molecule and hemicentin-1 as candidate proteins with cross-reactivity to the anti-mPD-L2 pAb. These results demonstrate that care is required in interpreting staining patterns generated when anti-PD-L2 pAb is used to locate PD-L2-expressing cells in the central nervous system and epithelial tissues, such as the olfactory epithelium. In addition, this anti-PD-L2 pAb may be used as an alternative antibody for labeling the olfactory epithelium during embryonic development in mice.ZHAO Yu BIAN GanLan YU CaiYong LIU Fang-Fang LIU Ling GUO HongMin GUO Jun JU Gong WANG Jian 2012Science China(Life Sciences)2012,55,11:0
18Inhibition of lysine-specific demethylase 1(LSD1)prevented tumor growth and metastasis by downregulating PD-L1 expression in lung adenocarcinoma显示文摘Lysine-specific demethylase 1(LSD1),as a histone lysine demethylase,demethylates monomethyl and dimethyl of histone H3 on lysine 4(H3K4)and lysine 9(H3K9).Studies have reported that high LSD1 expression promotes cell proliferation,migration,and invasion by regulating chromatin morphology and gene expression,and is closely related to the development of non-small cell lung cancer(NSCLC).1 However,the underlying mechanism of LSD1 on cell proliferation and migration remains unclear.Pengxing He Linna Du Pan Hao Han Yang Yufei Ren Huiqin Kang Yanli Ding Wen Zhao Yichao Xu Hongmin Liu 2023Genes & Diseases2023,10,5:0
19Copper-thioguanine metallodrug with self-reinforcing circular catalysis for activatable MRI imaging and amplifying specificity of cancer therapy显示文摘For chemotherapy, drug delivery systems often suffer from the inefficient drug loading capability, which usually cause systems toxicity and extra burden to excrete carrier itself. Moreover, the cancer therapeutic efficacy is also greatly limited by the specificity of tumor microenvironment for reactive oxygen species(ROS) based cancer therapeutic strategy(e.g., chemodynamic therapy). Herein, we have developed metal-drug coordination nanoplatform that can not only be responsive to tumor microenvironment but also modulate it, so as to achieve efficient treatment of cancer. Excitingly, by employing small molecule drug(6-thioguanine) as ligand copper ions, we achieve a high drug loading rate(60.1%) and 100% of utilization of metal-drug coordination nanoplatform(Cu-TG). Interestingly, Cu-TG possessed high-efficiently horseradish peroxidase-like, glutathione peroxidase-like and catalase-like activity. Under the tumor microenvironment, Cu-TG exhibited the self-reinforcing circular catalysis that is able to amplify the cellular oxidative stress, inducing notable cancer cellular apoptosis. Moreover, Cu-TG could be activated with glutathione(GSH) and facilitated for GSH triggered 6-TG release, higher selective therapeutic effect toward cancer cells, and GSH activated T1 weight-magnetic resonance imaging. Based on the above properties, Cu-TG exhibited magnetic resonance imaging(MRI) guiding, efficient and synergistic combination of chemodynamic and chemotherapy with self-reinforcing therapeutic outcomes in vivo.Haifeng Yuan Yan Zhao Chan Yang Cheng Zhang Yue Yang Hongmin Meng Shuangyan Huan Guosheng Song Xiaobing Zhang 2020Science China Chemistry2020,63,7:0
20Discovery of [1,2,4]triazolo[1,5-a]pyrimidine derivatives as new bromodomain-containing protein 4(BRD4) inhibitors显示文摘Targeting bromodomain-containing protein 4(BRD4) has been proved to be an effective strategy for cancer therapy.To date,numerous BRD4 inhibitors and degraders have been identified,some of which have advanced into clinical trials.In this work,a focused library of new [1,2,4]triazolo [1,5-a]pyrimidine derivatives were discovered to be able to inhibit BRD4.WS-722 inactivated BRD4(BD1/BD2),BRD2(BD1/BD2) and BRD3(BD1/BD2) broadly with the IC_(50) values less than 5 μmol/L.Besides,WS-722 inhibited growth of THP-1 cells with an IC_(50) value of 3.86 μmol/L.Like(+)-JQ1,WS-722 inhibited BRD4 in a reversible manner and enhanced protein stability.Docking studies showed that WS-722 occupied the central acetyl-lysine(Kac) binding cavity and formed a hydrogen bond with Asn140.In THP-1 cells,WS-722 showed target engagement to BRD4.Cellular effects of WS-722 on THP-1 cells were also examined,showing that WS-722 could block c-MYC expression,induce G0/G1 phase arrest and p21 up-regulation,and promote differentiation of THP-1 cells.BRD4 inhibition by WS-722 resulted in cell apoptosis and upregulated expression of cleaved caspased-3/7 and PARP in THP-1 cell lines.The [1,2,4]triazolo[1,5-a]pyrimidine is a new template for the development of new BRD4 inhibitors.Shuai Wang Dandan Shen Lijie Zhao Xiaohan Yuan Jialing Cheng Bin Yu Yichao Zheng Hongmin Liu 2020Chinese Chemical Letters2020,31,2:0
