| 1 | Targeted and effective photodynamic therapy for cancer using functionalized nanomaterials显示文摘Photodynamic therapy(PDT) is an emerging, non-invasive therapeutic strategy that involves photosensitizer(PS) drugs and external light for the treatment of diseases. Despite the great progress in PS-mediated PDT, their clinical applications are still hampered by poor water solubility and tissue/cell specificity of conventional PS drugs. Therefore, great efforts have been made towards the development of nanomaterials that can tackle fundamental challenges in conventional PS drug–mediated PDT for cancer treatment. This review highlights recent advances in the development of nano-platforms, in which various functionalized organic and inorganic nanomaterials are integrated with PS drugs, for significantly enhanced efficacy and tumor-selectivity of PDT. | Eun Ji Hong Dae Gun Choi Min Suk Shim | 2016 | Acta Pharmaceutica Sinica B2016，6，4： | 22 |
| 2 | Antibacterial photodynamic therapy:overview of a promising approach to fight antibiotic-resistant bacterial infections显示文摘Antibacterial photodynamic therapy(APDT)has drawn increasing attention from the scientific society for its potential to effectively kill multidrug-resistant pathogenic bacteria and for its low tendency to induce drug resistance that bacteria can rapidly develop against traditional antibiotic therapy.The review summarizes the mechanism of action of APDT,the photosensitizers,the barriers to PS localization,the targets,the in vitro-,in vivo-,and clinical evidence,the current developments in terms of treating Gram-positive and Gram-negative bacteria,the limitations,as well as future perspectives.Relevance for patients:A structured overview of all important aspects of APDT is provided in the context of resistant bacterial species.The information presented is relevant and accessible for scientists as well as clinicians,whose joint effort is required to ensure that this technology benefits patients in the post-antibiotic era. | Yao Liu Rong Qin Sebastian A.J.Zaat Eefjan Breukink Michal Heger | 2015 | Journal of Clinical & Translational Research2015，1，3： | 8 |
| 3 | Poly(ethylene glycol) conjugated nano-graphene oxide for photodynamic therapy显示文摘A novel methoxy-poly(ethylene glycol) modified nano-graphene oxide(NGO-mPEG) was designed and synthesized as a photosensitizer(PS) carrier for photodynamic therapy of cancer.NGO with a size below 200 nm was prepared using a modified Hummers' method.NGO was observed by AFM to exhibit a structure with single-layer graphene oxide sheets down to a few nanometers in height.Hydrophilic mPEG conjugation of NGO(NGO-mPEG) was found to enhance solubility in cell culture media.No apparent cytotoxicity of the NGO-mPEG was observed towards MCF-7 carcinoma cell line.Zinc phthalocyanine(ZnPc),a photosensitizer for photodynamic therapy,was loaded in the NGO-PEG through π-π stacking and hydrophobic interactions,with the drug loading efficiency up to 14 wt%.Hydrophobic ZnPc was internalized in MCF-7 cells,exhibiting a pronounced phototoxicity in the cells under Xe light irradiation.The results indicate a great potential of NGO-mPEG for photodynamic therapy of cancer. | Pilger FRANK | 2010 | Science China Chemistry2010，53，11： | 8 |
| 4 | Recent advances in photodynamic therapy based on emerging two-dimensional layered nanomaterials显示文摘Photodynamic therapy(PDT)is a promising non-invasive therapy approach for various diseases including malignant tumor.The process of PDT involves three interrelated aspects,namely photosensitizer(PS),light source,and oxygen,among which PS is the decisive factor that determines its anticancer efficiency.There exist some defects in currently applied PDT,such as inadequate production of reactive oxygen species(ROS),poor penetration of exciting light,insufficient oxygen supply,and nonselective distribution of PS.With unique physicochemical and optical properties,two-dimensional nanomaterials(2DNMs)have aroused great interest in biomedical fields.2DNMs-based PDT is promising to significantly improve antitumor efficacy compared to conventional PDT.In this review,we will firstly introduce the underlying mechanism of PDT and how 2DNMs are absorbed and distribute inside tumor cells.After that,we will not only illustrate how 2DNMs-based PDT can enhance tumor-killing efficacy and minimize side-effects through conquering the above-mentioned defects of conventional PDT and the preparation process of 2DNMs,but also elaborate recent advances about 2DNMs-based PDT.Lastly,we will summarize the challenges and future prospects of 2DNMs-based PDT. | Xinqiang Wu Xiaofeng Jiang Taojian Fan Zhiwei Zheng Zhaoyuan Liu Yubin Chen Liangqi Cao Zhongjian Xie Dawei Zhang Jiaqi Zhao Qiwen Wang Zhenhui Huang Zhijian Chen Ping Xue Han Zhang | 2020 | Nano Research2020，13，6： | 6 |
| 5 | Site-specific pharmaco-laser therapy:A novel treatment modality for refractory port wine stains显示文摘Despite extensive efforts to optimize laser therapy,i.e.,the current gold standard treatment,a majority of port wine stain(PWS)patients responds suboptimally to laser therapy.This paper describes the niceties of a novel PWS treatment modality termed site-specific pharmaco-laser therapy(SSPLT).In contrast to the classic approach of enhancing the extent of intravascular photocoagulation(the photothermal response),SSPLT focuses on optimization of post-irradiation thrombus formation(i.e.,the hemodynamic response)by combining conventional laser therapy with the administration of thermosensitive drug delivery systems that encapsulate prothrombotic and antifibrinolytic drugs.The aim of SSPLT is to instill complete lumenal occlusion in target vessels,which has been linked to optimal PWS blanching.Relevance for patients:The current treatment options for PWS patients are limited in efficacy.Novel therapeutic modalities are needed to more effectively treat patients with recalcitrant PWSs.SSPLT is an experimental-stage treatment modality that could serve as an adjuvant to pulsed dye laser therapy for a selected group of patients whose PWS is ill-responsive to standard treatment.The expected clinical result of SSPLT is improved lesional blanching. | M.Ingmar van Raath Jojanneke E.van Amesfoort Martin Hermann Yasin Ince Maurice J.Zwart Agustina V.Echague Yan Chen Baoyue Ding Xuan Huang Gert Storm Michal Heger | 2019 | Journal of Clinical & Translational Research2019，5，1： | 4 |
| 6 | Photosensitizer Nanoparticles Boost Photodynamic Therapy for Pancreatic Cancer Treatment显示文摘Patients with pancreatic cancer(PCa)have a poor prognosis apart from the few suitable for surgery.Photodynamic therapy(PDT)is a minimally invasive treatment modality whose efficacy and safety in treating unresectable localized PCa have been corroborated in clinic.Yet,it suffers from certain limitations during clinical exploitation,including insufficient photosensitizers(PSs)delivery,tumor-oxygenation dependency,and treatment escape of aggressive tumors.To overcome these obstacles,an increasing number of researchers are currently on a quest to develop photosensitizer nanoparticles(NPs)by the use of a variety of nanocarrier systems to improve cellular uptake and biodistribution of photosensitizers.Encapsulation of PSs with NPs endows them significantly higher accumulation within PCa tumors due to the increased solubility and stability in blood circulation.A number of approaches have been explored to produce NPs co-delivering multi-agents affording PDT-based synergistic therapies for improved response rates and durability of response after treatment.This review provides an overview of available data regarding the design,methodology,and oncological outcome of the innovative NPs-based PDT of PCa. | Huanyu Yang Renfa Liu Yunxue Xu Linxue Qian Zhifei Dai | 2021 | Nano-Micro Letters2021，13，2： | 3 |
| 7 | Design and synthesis of novel water-soluble amino acid derivatives of chlorin p6 ethers as photosensitizer显示文摘Eight new water-soluble amino acid conjugates 6 a-h of chlorin p6 ethers(5 a-d) were synthesized and preliminarily investigated for their in vitro PDT antitumor activity and structure-activity relationship(SAR). The results showed that all compounds exhibited much higher phototoxicity against tumor cells than talaporfin. SAR analysis indicated that PDT antitumor effect enhanced with the increase of carbon chain length of alkoxyl ether bonds at 3~1-position, and L-aspartic acid was superior to L-glutamic acid. In particular, the IC_50 values of most phototoxic compound 6 d were 0.20 mmol/L against A549 cell and0.41υmmol/L against B16-F10 cell, which individually represented 31-and 24-fold increase of antitumor potency compared to talaporfin, suggesting that it was a promising candidate photosensitizer(PS) for PDT applications due to its strong absorption at long wavelength, high phototoxicity, low dark cytotoxicity and good water-solubility. | Xingjie Zhang Zhi Meng Zhiqiang Ma Junhong Liu Guiyan Han Fujia Ma Ningyang Jia Zhenyuan Miao Wannian Zhang Chunquan Sheng Jianzhong Yao | 2019 | Chinese Chemical Letters2019，30，1： | 3 |
| 8 | Gold Nanostars-AIE Theranostic Nanodots with Enhanced Fluorescence and Photosensitization Towards Effective Image-Guided Photodynamic Therapy显示文摘Dual-functional aggregation-induced photosensitizers(AIE-PSs)with singlet oxygen generation(SOG)ability and bright fluorescence in aggregated state have received much attention in image-guided photodynamic therapy(PDT).However,designing an AIE-PS with both high SOG and intense fluorescence via molecular design is still challenging.In this work,we report a new nanohybrid consisting of gold nanostar(AuNS)and AIE-PS dots with enhanced fluorescence and photosensitization for theranostic applications.The spectral overlap between the extinction of AuNS and fluorescence emission of AIE-PS dots(665 nm)is carefully selected using five different AuNSs with distinct localized surface plasmon(LSPR)peaks.Results show that all the AuNS s can enhance the 1 O2 production of AIE-PS dots,among which the AuNS with LSPR peak at 585 nm exhibited the highest 1 O2 enhancement factor of15-fold with increased fluorescence brightness.To the best of our knowledge,this is the highest enhancement factor reported for the metalenhanced singlet oxygen generation systems.The Au585@AIE-PS nanodots were applied for simultaneous fluorescence imaging and photodynamic ablation of HeLa cancer cells with strongly enhanced PDT efficiency in vitro.This study provides a better understanding of the metal-enhanced AIE-PS nanohybrid systems,opening up new avenue towards advanced image-guided PDT with greatly improved efficacy. | Mohammad Tavakkoli Yaraki Min Wu Eshu Middha Wenbo Wu Soroosh Daqiqeh Rezaei Bin Liu Yen Nee Tan | 2021 | Nano-Micro Letters2021，13，4： | 3 |
| 9 | Evolution from small molecule to nano-drug delivery systems:An emerging approach for cancer therapy of ursolic acid显示文摘Ursolic acid(UA),a natural pentacyclic triterpenoid,possesses widespread biological and pharmacological activities.However,drawbacks such as low bioavailability,poor targeting and rapid metabolism greatly hinder its further clinical application.Recently,with the development of nanotechnology,various UA nanosystems have emerged as promising strategies for effective cancer therapy.This article reviews various types of UA-based nanodelivery systems,primarily with emphasis placed on novel UA-based carrier-free nanodrugs,which are considered to be innovative methods for cancer therapy.Moreover,this review presents carrier-free nano-drugs that co-assembled of UA and photosensitizers that displayed synergistic antitumor performance.Finally,the article also describes the development and challenges of UA nanosystems for future research in this field.Overall,the information presented in this review will provide new insight into the rational utilization of nano-drugs in cancer therapy. | Jingwei Shao Yifan Fang Ruirui Zhao Fangmin Chen Mingyue Yang Jiali Jiang Zixuan Chen Xiaotian Yuan Lee Jia | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，6： | 3 |
| 10 | Polyoxometalate-based high-nuclear cobalt-vanadium-oxo cluster as efficient catalyst for visible light-driven CO2 reduction显示文摘A high-nuclear Co-V-O cluster was firstly isolated by lacunary polyoxoanion, resulting in the high-nuclear mixed metal-oxo cluster-containing polyoxometalate (POM), K4Na28[{Co4(O-H)3(VO4)}4(SiW9O34)4]· 66H2O (1). In 1, the{Co4(O-H)3(VO4)}4{Co16-V4}core, composed of a{Co4O4}cubane, four{Co4(OH)3}qusi-cubanes and four VO4 units, was stabilized by four lacunary A-α-{SiW9O34} units. Photocatalytic study reveals that 1 exhibits excellent photocatalytic activity for CO2-to-CO conversion with high selectivity under visible light irradiation. The turnover number (TON) and turnover frequency (TOF) reaches as high as 10492 and 0.29 s^-1, respectively. Compound 1 represents the first high nuclear TM cluster-containing POM (TM=transition-metal) with efficient visible light catalytic activity for CO2 reduction, and its photocatalytic activity is much higher than those of most reported molecular catalysts. Photoluminescence spectroscopy study reveals that photoexcitation of Ru-photosensitizer is followed by an efficient electron transfer to POMs to reduce CO2. | Lizhen Qiao Man Song Aifang Geng Shuang Yao | 2019 | Chinese Chemical Letters2019，30，6： | 3 |
| 11 | X-ray-induced radiophotodynamic therapy (RPDT) using lanthanide micelles: Beyond depth limitations显示文摘We report lanthanide-based micelles integrating hypericin (Hyp) for X-ray- triggered photodynamic therapy (PDT). The lanthanide luminescence induced by X-ray irradiation excites the photosensitizer, which leads to the generation of singlet oxygen. This versatile approach can be extended to other photosensitizers or other types of liponanoparticles and can allow for magnetic resonance imaging (MRI) guidance. | Slavka Kascakova Alexandre Giuliani Sara Lacerda Agnes Pallier Pascal Mercere eva Toth Matthieu Refregiers | 2015 | Nano Research2015，8，7： | 2 |
| 12 | Advances in photosensitizer-related design for photodynamic therapy显示文摘Photodynamic therapy(PDT)is highly effective in treating tumors located near body surface,offering strong tumor suppression and low damage to normal tissue nearby.PDT is also effective for treating a number of other conditions.PDT not only provide a precise and selective method for the treatment of various diseases by itself,it can also be used in combination with other traditional therapies.Because PDT uses light as the unique targeting mechanism,it has simpler and more direct targeting capability than traditional therapies.The core material of a PDT system is the photosensitizer which converts light energy to therapeutic factors/substances.Different photosensitizers have their distinct characteristics,leading to different advantages and disadvantages.These could be enhanced or compensated by using proper PDT system.Therefore,the selected type of photosensitizer would heavily influence the overall design of a PDT system.In this article,we evaluated major types of inorganic and organic PDT photosensitizers,and discussed future research directions in the field. | Zhaojie Zhou Ling Zhang Zhirong Zhang Zhenmi Liu | 2021 | Asian Journal of Pharmaceutical Sciences2021，16，6： | 2 |
| 13 | Two-photon spectroscopic behaviors and photodynamic effect on the BEL-7402 cancer cells of the new chlorophyll photosensitizer显示文摘The spectroscopic properties of a new chlorophyll derivate photosensitizer(CDP) are studied under the excitation wavelengths at 800 and 400 nm using femtosecond pulses from a Ti:sapphire laser.The damaging effect of CDP on the BEL-7402 cancer cells is also investigated upon two-photon illumination at 800 nm.The normalized fluorescence spectra of CDP in tetrahydrofuran(THF) show that two-photon and one-photon spectra have the same distributions and the same emission bands(675 nm).The life-times of two-and one-photon induced fluorescence of this molecule are of the order of 5.0 ns.By comparing the data it is shown that there is some difference between the two lifetimes,but the differ-ence is less than one nanosecond.The two-photon absorption cross section of the molecule is also measured at 800 nm and estimated as about σ′2 ≈ 31.5×10-50 cm4·s·photon-1.The results of two-photon photodynamic therapy(TPPDT) tests show that CDP can kill all of the tested cancer cells according to the usual Eosine assessment.Our results indicate that the two-photon-induced photophysical,photo-chemical and photosensitizing processes of CDP may be basically similar to those of one-photon ex-citation.These behaviors of the sample suggest that one may find other possible methods to estimate some photosensitizers' effects in details such as their distribution in cells and the reactive targets of the sub-cellular parts of some tumor cells via two-photon excitation techniques. | ZHAO PeiDe1,2,CHEN Ping1,TANG GuoQing1,LIU JinWei2,LIN Lie1,GUO Peng1,YU Qing2, YAO JianZhong3,MA DongMing4,ZHANG GuiLan1 & CHEN WenJu1 1 Key Laboratory of Optoelectronic Information Science and Technology,Ministry of Education,Institute of Modern Optics,Nankai University,Tianjin 300071,China 2 Department of Physics,Hebei University of Technology,Tianjin 300130,China 3 College of Pharmacy,Second Military Medical University,Shanghai 200433,China 4 Tianjin College of the Traditional Chinese Medicine,Tianjin 300193,China | 2008 | Science China Chemistry2008，51，6： | 2 |
| 14 | 基于硝基苯甲酸结构的新型AIE光敏剂的光动力抗菌作用显示文摘光动力疗法在抗菌领域中的应用备受关注.传统的光敏剂在水性介质中容易聚集,从而减少活性氧的产生并严重影响其光动力抗菌疗效.为了减少传统光敏剂的聚集,研究人员做出了许多努力.与之相反,聚集诱导发光型的光敏剂(AIE-PSs)利用其聚集的优势,不仅增加了活性氧产量,而且增强了荧光强度.然而目前有关抗菌型AIE-PSs的研究仍处在发展阶段,相关报道也非常有限.我们在此首次报道了系列基于硝基苯甲酸结构的高效抗菌型AIE-PSs.其中带负电荷的TTVBA不仅可选择性地灭杀球形细菌(如金黄色葡萄球菌),而且易于被扩展成多种带正电荷且具有广谱抗菌性能的AIE-PSs(如TTVBP1–3).我们发现,TTVBP2在125 nmol L^(-1)的低浓度下,即可灭杀3.0 log_(10)金黄色葡萄球菌;TTVBP3在1μmol L^(-1)浓度下可灭杀4.7 log_(10)表皮葡萄球菌,在5μmol L^(-1)浓度下可灭杀3.8 log_(10)大肠杆菌,成为目前已报道的最有效的抗菌AIE-PSs.此外,这些AIE-PSs直接与细菌混合后,即对细菌具有出色的免洗成像能力.因此,我们认为基于硝基苯甲酸结构的TTVBA为未来高效抗菌光敏剂的设计提供了崭新思路. | 王欢欢 潘小宏 王亚琪 刘雯珍 戴涛 袁彬彬 陈学元 陈卓 | 2021 | Science China Materials2021，64，10： | 1 |

| 16 | Photothermy-strengthened photocatalytic activity of polydopamine-modified metal-organic frameworks for rapid therapy of bacteria-infected wounds显示文摘Herein,a metal-organic framework(MOF)was modified using polydopamine(PDA)to develop the MOFPDA as a photoresponsive bacteria-killing agent under 660 nm light irradiation.The modification using PDA led to the production of not only more heat,but also much more~1O_(2).This is because the PDA could interact with the porphyrin ring of the MOF throughπ-πinteraction and the charge transfer between PDA and the MOFs decreases the ene rgy of the band of hybrid nanoparticles.In addition,greater levels of hyperthermia induced by PDA modification accelerated the charge trans fe r,which significantly strengthened the photocatalytic perfo rmance of MO F-PDA.Furthermore,after modification,the light abso rbance and water dispersibility of nanoparticles were both enhanced;both are important for the improvement of photocatalytic and photothermal properties.Consequently,MOF-PDA exhibited the highly effective antibacterial efficacy of 99.62%and 99.97%against Staphylococcus aureus and Escherichia coli,respectively,under 20 min 660 nm light irradiation. | Donglin Han Yuan Li Xiangmei Liu Kelvin Wai Kwok Yeung Yufeng Zheng Zhenduo Cui Yanqin Liang Zhaoyang Li Shengli Zhu Xianbao Wang Shuilin Wu | 2021 | Journal of Materials Science & Technology2021，，3： | 1 |
| 17 | Efficient Co@Co_(3)O_(4) core-shell catalysts for photocatalytic water oxidation and its behaviors in two different photocatalytic systems显示文摘The photocatalytic performances of water oxidation were usually carried out in two different systems,photosensitizer and non-photosensitizer systems.There is few report about the same catalyst used in two systems and therefore it is of great significant to compare its role of the same catalyst in two systems and explore its different reaction mechanisms.In this work,first 4 kinds of metallic Co microparticles were obtained by different reduction methods through hydrothermal processes,and Co@Co_(3)O_(4) coreshell microparticles(1-4)were obtained from these metallic Co microparticles oxidized in air or in the reacting solution in situ.The core-shell structure of 1 was characterized by a series of analytical techniques.1-4 exhibited excellent activities and stabilities in the[Ru(bpy)3]^(2+)/S_(2) O_(8)^(2-)/light system when they were used as catalysts for the photocata lytic water oxidation.The maximum O2 evolution of 1 after 20 min’s illumination was 98.2 pmol,the O_(2) yield was 65.5%,the initial turnover frequency was 6.6×10^(-3),the initial quantum efficiency(ΦQYinitial)was 15.0%higher than Co(8.3%),CoO(11.7%),Co_(2)O_(3)(1.2%),Co_(3)O_(4)(2.8%)and 5(2.2%).Even after the sixth run,the catalytic activity of recovered 1 still remained 85.1%of initial activity.In addition,the photocatalytic performances of 1 in the[Ru(bpy)_(3)]^(2+)/S_(2)O_(8)2-/light system and S_(2) O_(8)^(2-)/light system were compared for the first time.In the nonphotosensitizer system,1 shows bifunctional roles and acts as optical absorption center and active catalytic site,and oxygen evolution rate is lower and it takes longer time.In the photosensitizer system,1 only acts as a catalyst,the photosensitizer enhances the light absorption and promotes water oxidation reaction with higher O_(2) yield and QE,meanwhile the photosensitizer brings the defect of high cost and instability into the system.Based on the results the two different reaction mechanisms were deeply discussed. | Di Wang Shanshan Qiao Jia Guo Yuan Guo Qian Xu Naeem Akram Jide Wang | 2021 | Journal of Energy Chemistry2021，30，6： | 1 |

| 19 | Recent progresses on the development of thioxo-naphthalimides显示文摘Thioxo/dithioxo-naphthalimide is a class of rarely visited fluorophore,first synthesized in 1999.Facile chemistry was devised to achieve mono or dual thionation of the two carbonyl groups of 1,8-naphthalimide.Thionation effectively shifts absorption maximum to longer spectral wavelength,significantly increase absorption coefficients,and dramatically enhances intersystem crossing efficiency with respect to their oxo-analogues.They were first explored as potent photocleavers to induce DNA strand break and novel photosensitizers for photodynamic therapies.In recent years,the unique chemistry of thioxo groups has been harnessed to achieve new applications,such as fluorescent sensors for heave metal ions.These unique photochemical and photophysical characteristics revitalize them intriguing functional molecules to investigate.In this short review,we wish to revisit their first discovery,facile synthesis,and the endeavors on the use of thioxo/dithioxo-naphthalimides for novel chemical and biomedical applications. | Xiao Luo Youjun Yang Xuhong Qian | 2020 | Chinese Chemical Letters2020，31，11： | 1 |
| 20 | A Highly Efficient Aggregation-induced Emission Photosensitizer for Photodynamic Combat of Multidrug-resistant Bacteria显示文摘With the antibiotic abuse and the resulting increased antibiotic resistance,the bacterial infection has posed a serious threat to human health.Photodynamic therapy is an effective tool for treating localized and superficial infections.It is a promising approach for the treatment of superbugs and with minimal risk of induced antibiotic resistance.Herein,an isoquinolinium-based photosensitizer,LIQ-TPE,with aggregation-induced emission properties is designed and synthesized.It is with high 1O2 generation efficiency and shows efficient antibacterial performance towards both Gram-negative and Gram-positive bacteria,and even methicillin-resistant Staphylococcus aureus(MRSA).LIQ-TPE thus shows great promise as an effective antimicrobial agent to combat the menace of multi-drug resistant bacteria. | ZOU Qian WANG Jia-Li WU Ming-Yu KAM LEE Sin-Ying FENG Shun CHEN Sijie | 2021 | Chemical Research in Chinese Universities2021，37，1： | 1 |
