Photosensitizers for Photodynamic Therapy

Advanced Healthcare Materials, Journal Year: 2019, Volume and Issue: 8(13)

Published: May 8, 2019

Abstract As an emerging clinical modality for cancer treatment, photodynamic therapy (PDT) takes advantage of the cytotoxic activity reactive oxygen species (ROS) that are generated by light irradiating photosensitizers (PSs) in presence (O 2 ). However, further advancements including tumor selectivity and ROS generation efficiency still required. Substantial efforts devoted to design synthesize smart PSs with optimized properties achieving a desirable therapeutic efficacy. This review summarizes recent progress developing intelligent efficient PDT, ranging from single molecules delicate nanomaterials. The strategies improve through optimizing photoinduced electron transfer energy processes highlighted. Moreover, approaches combine PDT other therapeutics (e.g., chemotherapy, photothermal therapy, radiotherapy) targeted delivery cells or tissue introduced. main challenges application also discussed.

Molecular Targeting‐Mediated Mild‐Temperature Photothermal Therapy with a Smart Albumin‐Based Nanodrug

Small, Journal Year: 2019, Volume and Issue: 15(33)

Published: July 7, 2019

Abstract Photothermal therapy (PTT) usually requires hyperthermia >50 °C for effective tumor ablation, which inevitably induces heating damage to the surrounding normal tissues/organs. Moreover, low retention and high liver accumulation are two main obstacles that significantly limit efficacy safety of many nanomedicines. To solve these problems, a smart albumin‐based microenvironment‐responsive nanoagent is designed via self‐assembly human serum albumin (HSA), dc‐IR825 (a cyanine dye photothermal agent), gambogic acid (GA, heat shock protein 90 (HSP90) inhibitor an anticancer agent) realize molecular targeting‐mediated mild‐temperature PTT. The formed HSA/dc‐IR825/GA nanoparticles (NPs) can escape from mitochondria cytosol through mitochondrial disruption under near‐infrared (NIR) laser irradiation. GA molecules block hyperthermia‐induced overexpression HSP90, achieving reduced thermoresistance cells PTT at mild temperature (<45 °C). Furthermore, NPs show pH‐responsive charge reversal, accumulation, negligible deposition, ultimately facilitating synergistic chemotherapy. Taken together, NIR‐activated allow release drugs more precisely, ablate tumors effectively, inhibit cancer metastasis persistently, will advance development novel PTT‐based combination strategies.

Covalent Organic Polymers Based on Fluorinated Porphyrin as Oxygen Nanoshuttles for Tumor Hypoxia Relief and Enhanced Photodynamic Therapy

Advanced Functional Materials, Journal Year: 2018, Volume and Issue: 28(43)

Published: Sept. 11, 2018

Abstract Effective and sustained tumor oxygenation has found practical significance in benefiting the treatment of solid tumors. In this study, fluorinated covalent organic polymers (COPs) are prepared by cross‐linking photosensitizer meso‐5, 10, 15, 20‐tetra (4‐hydroxylphenyl) porphyrin (THPP) with perfluorosebacic acid (PFSEA) poly(ethylene glycol) (PEG) via a one‐pot esterification, to enable simultaneous photodynamic treatment. Due presence PFSEA, obtained THPP pf –PEG shows efficient loading perfluoro‐15‐crown‐5‐ether (PFCE), type perfluocarbon, thereby molecular oxygen, both which would significantly enhance effect THPP. After chelating radio‐isotope, 99m Tc, PFCE‐loaded (PFCE@THPP –PEG) can be vividly visualized under single‐photon emission computed tomography (SPECT) imaging, uncovers accumulation those COPs' post intravenous injection. Owing oxygen delivery ability PFCE, is observed for mice injection PFCE@THPP –PEG, further leads greatly enhanced This study presents unique multifunctional COPs well‐defined composition, long blood circulation time, ability, showing great promises potential clinical translation

Magnetic Targeting of Nanotheranostics Enhances Cerenkov Radiation-Induced Photodynamic Therapy

Journal of the American Chemical Society, Journal Year: 2018, Volume and Issue: 140(44), P. 14971 - 14979

Published: Oct. 18, 2018

The interaction between radionuclides and nanomaterials could generate Cerenkov radiation (CR) for CR-induced photodynamic therapy (PDT) without requirement of external light excitation. However, the relatively weak CR leaves clinicians uncertain about benefits this new type PDT. Therefore, a novel strategy to amplify therapeutic effect PDT is imminently required overcome disadvantages traditional nanoparticulate such as tissue penetration limitation, dependence, low tumor accumulation photosensitizers. Herein, magnetic nanoparticles (MNPs) with 89Zr radiolabeling porphyrin molecules (TCPP) surface modification (i.e., 89Zr-MNP/TCPP) were synthesized targeting delivery. As break depth dependence PDT, these 89Zr-MNP/TCPP exhibited high under presence an field, contributing excellent together fluorescence, luminescence (CL), resonance energy transfer (CRET) multimodal imaging monitor process. present study provides major step forward in by developing advanced phototherapy tool magnetism-enhanced effective treatment tumors.
