Increased Free Radical Generation during the Interaction of a Quinone-Quinoline Chelator with Metal Ions and the Enhancing Effect of Light. Pharmaceuticals (Basel) 2023; 16:1116. [PMID: 37631031 PMCID: PMC10459951 DOI: 10.3390/ph16081116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/27/2023] Open
Abstract
Schiff bases and similar molecules forming metal complexes may cause redox effects, which may also be influenced by light. Anthraquinones such as doxorubicin and idarubicin are widely used antitumor agents, which can generate reactive oxygen species (ROS), stimulated by both the presence of iron and copper ions and also by light. The generated ROS can cause DNA scission, cell membrane oxidation, and many other toxic effects. The redox activity of the quinone-quinoline chelator 2-phenyl-4-(butylamino)naphtho [2,3-h]quinoline-7,12-dione (Q1) was investigated in the presence of iron, copper, and zinc. The influence of light in these interactions was also examined. The chemically induced dynamic nuclear polarization (CIDNP), nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR) methods were used to elucidate the molecular changes and ROS generation effects of the Q1 metal interactions. A model electron transfer reaction system between 1,4-dihydropyridine and Q1 was utilized to demonstrate that the chelate complexes of Q1 with both Fe(III) and Cu(II) ions were more redox active than Q1 itself. Similarly, CIDNP and NMR data showed that the concentration dependence of the free radicals yield is much higher in the presence of Fe(III) and Cu(II) ions, in comparison to Zn(II), and also that it increased in the presence of light. These findings underline the role of transition metal ions and Q1 in cyclic redox chain reactions and increase the prospect of the development of copper- and iron-based chelating agents, including Q1 and its derivatives, for anticancer therapy. Furthermore, these findings also signify the effect of light on enhancing ROS formation by Q1 and the prospect of utilizing such information for designing target specific anticancer drugs for photodynamic therapy.

Abstract
The current study was performed to investigate the treatment of tumors with gold nanoparticles, laser, and photodynamic therapy (PDT) by using an immunohistochemistry method and to investigate the expression of FOXP1 in infected mice with mammary adenocarcinoma whether it can be used as an indicator to estimate the recovery of tissues from cancer disease. Twenty-five albino female mice were used in this research; they were divided into five groups, four groups were infected with mammary adenocarcinoma, and then three of them were treated with gold nanoparticles, laser, and PDT, respectively, while the fourth group was left without any treatment and represents the positive control, and the fifth group (normal mice) represents the negative control. Tissue sections were taken from different groups of mice in order to estimate FOXP1 expression in infected mice by using an immunohistochemistry assay. FOXP1 expression was higher in the tumor and kidney tissues of the mice treated with PDT than that in mice treated with either gold nanoparticles or laser alone. Also, in the group of mice treated with laser, FOXP1 expression was higher than the expression in mice which were treated with gold nanoparticles but lower than that in mice which were treated with PDT. FOXP1 can be used as a biomarker for the prognosis outcome of breast and other solid tumors, as well as it considers a key tumor suppressor. PDT is the best choice to treat cancer in comparison to using either gold nanoparticles or the laser separately.

Fraxetin Interacts Additively with Cisplatin and Mitoxantrone, Antagonistically with Docetaxel in Various Human Melanoma Cell Lines-An Isobolographic Analysis. Int J Mol Sci 2022; 24:ijms24010212.

Abstract
Malignant melanoma is a skin cancer characterized by rapid development, poor prognosis and high mortality. Due to the frequent drug resistance and/or early metastases in melanoma, new therapeutic methods are urgently needed. The study aimed at assessing the cytotoxic and antiproliferative effects of scoparone and fraxetin in vitro, when used alone and in combination with three cytostatics: cisplatin, mitoxantrone, and docetaxel in four human melanoma cell lines. Our experiments showed that scoparone in the concentration range tested up to 200 µM had no significant effect on the viability of human malignant melanoma (therefore, it was not possible to evaluate it in combination with other cytostatics), while fraxetin inhibited cell proliferation with IC50 doses in the range of 32.42-73.16 µM, depending on the cell line. Isobolographic analysis allowed for the assessment of the interactions between the studied compounds. Importantly, fraxetin was not cytotoxic to normal keratinocytes (HaCaT) and melanocytes (HEMa-LP), although it slightly inhibited their viability at high concentrations. The combination of fraxetin with cisplatin and mitoxantrone showed the additive interaction, which seems to be a promising direction in melanoma therapy. Unfortunately, the combination of fraxetin with docetaxel may not be beneficial due to the antagonistic antiproliferative effect of both drugs used in the mixture.

Abstract
Anthraquinone class of compounds possesses a broad spectrum of therapeutic applications. Cancer cell targeting ability, together with photogeneration of reactive oxygen species, renders anthraquinones an interesting class of photosensitizers for photodynamic therapy (PDT). Screening of newer compounds for better singlet oxygen generation is of current interest to improve the practical usability in PDT. In this study, we investigate the photodynamic activity of nine commercially available anthraquinones, using EPR spectroscopy and computational techniques, to identify the role of substituents on singlet oxygen yield. Three anthraquinone derivatives, 1,5-diaminoanthraquinone, 15-dihydroxyanthraquinone and 1,2,7-trihydroxyanthraquinone, showed highest singlet oxygen quantum yield (0.21, 0.18 and 0.15, respectively) relative to Rose Bengal. Time-dependent density functional theory calculations indicate the singlet oxygen quantum yield of anthraquinones inversely correlate well with the excited singlet-triplet (S1-T1) energy gap. Electron-donating substituents present at positions 1, 2 and 5 of anthraquinone seem to reduce the S1-T1 energy gap, facilitating inter-system crossing and the production of singlet oxygen. This would greatly aid in the design of newer anthraquinone-based photosensitizers. This study also highlights the suitability of 1,5-diaminoanthraquinone for PDT applications as demonstrated by in vitro experiments of photoinduced DNA cleavage and photocytotoxicity in Dalton's lymphoma ascites.

Abstract
Tumor immunotherapy is only effective in a fraction of patients due to a low response rate and severe side effects, and these challenges of immunotherapy in clinics can be addressed through induction of immunogenic cell death (ICD). ICD is elicited from many antitumor therapies to release danger associated molecular patterns (DAMPs) and tumor‐associated antigens to facilitate maturation of dendritic cells (DCs) and infiltration of cytotoxic T lymphocytes (CTLs). The process can reverse the tumor immunosuppressive microenvironment to improve the sensitivity of immunotherapy. Nanostructure‐based drug delivery systems (NDDSs) are explored to induce ICD by incorporating therapeutic molecules for chemotherapy, photosensitizers (PSs) for photodynamic therapy (PDT), photothermal conversion agents for photothermal therapy (PTT), and radiosensitizers for radiotherapy (RT). These NDDSs can release loaded agents at a right dose in the right place at the right time, resulting in greater effectiveness and lower toxicity. Immunotherapeutic agents can also be combined with these NDDSs to achieve the synergic antitumor effect in a multi‐modality therapeutic approach. In this review, NDDSs are harnessed to load multiple agents to induce ICD by chemotherapy, PDT, PTT, and RT in combination of immunotherapy to promote the therapeutic effect and reduce side effects associated with cancer treatment.

Abstract
Traditional cancer therapy is limited by poor prognosis and risk of recurrence. Emerging therapies offer alternatives to these problems. In addition, synergistic therapy can combine the advantages of multiple therapies to eliminate cancer cells while attenuating damage to normal tissues. Herein, a theranostic nanoplatform based on the chemotherapeutic drug mitoxantrone (MTO) and glucose oxidase (GOx) co-loaded γ-Fe2 O3 nanoparticles (MTO-GOx@γ-Fe2 O3 NPs) is designed and prepared to realize photoacoustic imaging-guided chemo/chemodynamic/photothermal (CT/CDT/PTT) synergistic cancer therapy. With a particle size of about 86.2 nm, the synthesized MTO-GOx@γ-Fe2 O3 NPs can selectively accumulate at tumor sites by enhanced permeability and retention (EPR) effects. After entering cancer cells by endocytosis, MTO-GOx@γ-Fe2 O3 NPs decompose into Fe3+ ions and release cargo because of their pH-responsive characteristic. As a Food and Drug Administration (FDA)-approved chemotherapy drug, MTO shows strong DNA disruption ability and satisfying photothermal conversion ability under laser irradiation for photothermal therapy. Simultaneously, GOx catalyzes the decomposition of glucose and generates hydrogen peroxide (H2 O2 ) to enhance the chemodynamic therapy efficiency. In vitro and in vivo experiments reveal that MTO-GOx@γ-Fe2 O3 NPs possess a significant synergistic therapeutic effect in cancer treatment.

Abstract
Cervical cancer is recognized as a serious worldwide health problem. Despite various achievements for cervical cancer treatment, there are still shortcomings that lead to severe side effects. Combination therapy is fast becoming a key and promising treatment strategy, diminishing chemotherapy-mediated side effects. The objective of this study was to determine the effect of combined cisplatin treatment and photodynamic therapy (PDT) on the cervical cancer recovery. In this study, A2780 and A2780-CP cell lines were cultured in the Dulbecco's modified eagle medium (DMEM) enriched with 10% FBS and 1% antibiotic. Both cell lines were treated with cisplatin, photodynamic light (laser with methylene blue as a photosensitizer agent), and the combination of cisplatin treatment and PDT. Half maximum inhibitory concentration (IC50) was calculated for each treatment by the use of tetrazolium salt assay. Both cell lines were examined for cell membrane lipid peroxidation rate. Our findings showed that combination of cisplatin treatment and photodynamic therapy leads to two-fold decreased cisplatin IC50. Results showed that cisplatin and photodynamic light combination could effectively reduce A2780 and A2780-CP cell viability (p-value < 0.0001). Moreover, combined cisplatin and photodynamic therapy results revealed significantly increased cancer cell membrane destruction through increased lipid peroxidation, resulting in surged MDA content. Our conclusion is that combination of cisplatin and photodynamic therapy can be used as an effective and convenient treatment strategy without considerable side effects.

Abstract
Photodynamic therapy presents a therapeutic choice that can be utilized to treat diverse neoplasms. In this technique, the critical element is a photosensitive molecule that absorbs light energy and transfers it to molecular oxygen or biological molecules to form reactive oxygen species, thus inducing irreversible damage to target cells and ultimately leading to cell death. Bacteriochlorin derivatives are employed as photosensitizers (PSs), possessing light-absorbing capacity in the near-infrared region. The objective of this study was to prepare a semi-synthetic bacteriochlorin from Rhodopseudomonas faecalis and adding Trizma® to improve solubility. Cell viability tests, flow cytometry (apoptotic and necrotic cells were identified by Annexin V and propidium iodide), and confocal microscopy were used to evaluate the photoactivity of bacteriochlorin-Trizma (Bchl-T) in fibroblast (HFF-1-control cells) and breast cancer (MCF-7 cells-target cells) cells. At concentrations above 0.5 μM, Bchl-T demonstrated 80 % cell death, presenting the highest PS interaction (via fluorescence microscopy) with lysosomes, mitochondria, and the endoplasmic reticulum; the cell death type was revealed as apoptosis (via cytometry). Our findings indicated the suitability of Bchl-T for future application in photodynamic therapy against cancer cells by inducing apoptosis.

Abstract
OBJECTIVES Methylene blue (MB) is a commonly used dye that can be used for near-infrared (NIR) imaging and photodynamic therapy (PDT) by producing reactive oxygen species after light exposure, inducing apoptosis. The limiting factor of MB is its poor penetration through cell membranes. Its decreased cellular uptake can be prevented by encapsulation in drug delivery systems such as liposomes. Additionally, the enhanced permeability and retention effect of tumors enables enhanced accumulation of nanocarriers at the target site. MATERIALS AND METHODS Nanosized, MB encapsulated, Tc-99m radiolabeled Lipoid S PC:PEG2000-PE:Chol: DTPA-PE and DPPC:PEG2000-PE:Chol:DTPA-PE liposomes were formulated to design multifunctional theranostic nanocarriers for: 1) NIR imaging, 2) gamma probe detection of sentinel lymph nodes (SLNs), and 3) PDT, which can provide accurate imaging and therapy helping surgery with a single liposomal system. The characterization of liposomes was performed by measuring particle size, zeta potential, phospholipid content, and encapsulation efficiency. Additionally, the in vitro release profile of MB and physical stability were also evaluated over 6 months at determined time intervals by measuring the mean particle size, zeta potential, encapsulation efficiency, and phospholipid content of liposomes kept at room temperature (25°C) and 4°C. RESULTS Tc-99m radiolabeled, nanosized Lipoid S PC:PEG2000-PE:Chol:DTPA-PE and DPPC:PEG2000-PE:Chol:DTPA-PE liposomes showed suitable particle size (around 100 nm), zeta potential (-9 to -13 mV), encapsulation efficiency (around 10%), phospholipid efficiency (around 85-90%), and release profiles. Additionally, the liposomes found stable for 3 months especially when kept at 4°C. CONCLUSION MB encapsulated, Tc-99m radiolabeled, nanosized Lipoid S PC:PEG2000-PE:Chol:DTPA-PE and DPPC:PEG2000-PE:Chol:DTPA-PE liposomes were found to have potential for SLN imaging by gamma probe detection, NIR imaging, and PDT. In vitro and in vivo imaging and therapeutic efficiency should be definitely evaluated to enable a final decision and our studies on this research topic are continuing.

Abstract
Chlorophyll a exhibits excellent photosensitive activity in photosynthesis. The unstability limited its application as photoensitizer drug in photodynamic therapy. Here a series of novel chlorophyll a degradation products pyropheophorbide-a derivatives were synthesized and evaluated for lung cancer in PDT. These compounds have strong absorption in 660-670 nm with high molar extinction coefficient, and fluorescence emission in 660-675 nm upon excitation with 410-415 nm light. They all have much higher ROS yields than pyropheophorbide-a, and compound 10 was even higher than [3-(1-hexyloxyethyl)]-pyrophoeophorbide a (HPPH). Distinctive phototoxicity was observed in vitro and the inhibition effect was in light dose-dependent and drug dose-dependent style. They can effectively inhibit the growth of lung tumor in vivo. Among them, compound 8 and 11 have outstanding photodynamic anti-tumor effects without obvious skin photo-toxicity, so they can act as new drug candidates for photodynamic therapy.

Abstract
BACKGROUND In recent years, Mitoxantrone (MTX) has been introduced as a chemotherapy drug which also serves as a photosensitizer and radiosensitizer. Due to its serious side effects, there are limitations to the application of MTX so scientists are looking for solutions to overcome this problem. Hollow gold nanoparticles (HAuNP) have attracted growing attention due to their unique physical-chemical properties, such as biocompatibility, tunable plasmonic absorption peak ranging from visible to near infrared, high stability and various medical applications in imaging, drug delivery and combinational cancer treatments. In this paper, the combinational effect of photodynamic therapy (PDT) and chemotherapy of MTX conjugated to HAuNP is studied. METHOD After optimizing the synthesis of PEGylated HAuNP and preparing nanostructures conjugated with MTX, the characteristics of pharmacological agents including MTX, HAuNP, mPEG-HAuNP,and MTX-mPEG-HAuNP and their toxicity were determined at different concentrations on two cell lines of DFW and MCF7 derived from human melanoma and breast cancer, respectively. To select the optimal concentration for PDT, the cytotoxicity of agents was investigated at concentrations of 3, 6, 9 and 12 μM. Moreover, a LEDs system at 630 nm and power output of 3 W was used to apply PDT process. MTT test was used to determine cell survival 24 h after treatment. Several indexes were utilized for data comparison, such as therapeutic efficacy (TE), necessary concentration to kill 50% of cells (IC50), and necessary light exposure to induce 50% cell death (ED50). RESULTS LED exposure alone did not cause significant cell death. For MTX-mPEG-HAuNP, at both cell lines, IC50 had the least exposure to dark condition with an exposure time of less than 9 min and this nanostructure had the smallest ED50 in each cell line at all concentrations. TE of MTX-mPEG-HAuNP at different exposures and concentrations was greater than 1 for the DFW cells. It was also true for concentrations greater than 6 μM with irradiation times longer than 3 min for MCF7 cells. CONCLUSION This is the first paper to use PEGylated hollow gold nanoparticles as the nanocarrier for MTX. The results indicated that MTX-mPEG-HAuNP improved the efficacy of PDT with Light Emission diode.

Abstract
Hepatocellular carcinoma (HCC) is frequently metastatic once diagnosed and less likely to respond to curative surgery, emphasizing the need for the development of more sensitive and effective diagnostic and therapeutic strategies. Epithelial cell adhesion molecule (EpCAM) is deemed as the biomarker of cancer stem cells (CSCs), which are mainly responsible for the recurrence, metastasis and prognosis of HCC. In this study, we discuss the use of mitoxantrone (MX), an antitumor drug and a photosensitizer, for designing upconversion nanoparticle-based micelles grafted with the anti-EpCAM antibody, for dual-modality magnetic resonance/upconversion luminescence (MR/UCL)-guided synergetic chemotherapy and photodynamic therapy (PDT). The obtained micelles exhibit good biocompatibility, high specificity to HCC cells and superior fluorescent/magnetic properties in vitro. In vivo results demonstrate that the targeted micelles exhibited much better MR/UCL imaging qualities compared to the nontargeted micelles after the intravenous injection. More importantly, PEGylated UCNP micelles loaded with MX and grafted with anti-EpCAM antibody, denoted as anti-EpCAM-UPGs-MX, showcased the most effective synergetic antitumor efficacy compared with other treatment groups both in vitro and vivo. The remarkable antitumor effect, coupled with superior simultaneous dual-modality MR/UCL imaging as well as good biocompatibility and negligible toxicity, makes the UPG micelles promising for future translational research in HCC diagnosis and therapy.

Abstract
Mitoxantrone (MIT) is an anticancer agent with photosensitive properties that is commonly used in various cancers. Multidrug resistance (MDR) effect has been an obstacle to using MIT for cancer therapy. Photochemical internalization, on account of photodynamic therapy, has been applied to improve the therapeutic effect of cancers with MDR effect. In this study, an MIT-poly(ε-caprolactone)-pluronic F68-poly(ε-caprolactone)/poly(d,l-lactide-co-glycolide)–poly(ethylene glycol)–poly(d,l-lactide-co-glycolide) (MIT-PFP/PPP) mixed micelles system was applied to reverse the effect of MDR in MCF-7/ADR cells via photochemical reaction when exposed to near-infrared light. MIT-PFP/PPP mixed micelles showed effective interaction with near-infrared light at the wavelength of 660 nm and exerted great cytotoxicity in MCF-7/ADR cells with irradiation. Furthermore, MIT-PFP/PPP mixed micelles could improve reactive oxygen species (ROS) levels, decrease P-glycoprotein activity, and increase the cellular uptake of drugs with improved intracellular drug concentrations, which induced cell apoptosis in MCF-7/ADR cells under irradiation, despite MDR effect, as indicated by the increased level of cleaved poly ADP-ribose polymerase. These findings suggested that MIT-PFP/PPP mixed micelles may become a promising strategy to effectively reverse the MDR effect via photodynamic therapy in breast cancer.

Abstract
BACKGROUND Breast cancer is the main cause of mortality among women. The disease presents high recurrence mainly due to incomplete efficacy of primary treatment in killing all cancer cells. Photodynamic therapy (PDT), an approach that causes tissue destruction by visible light in the presence of a photosensitizer (Ps) and oxygen, appears as a promising alternative therapy that could be used adjunct to chemotherapy and surgery for curing cancer. However, the efficacy of PDT to treat breast tumours as well as the molecular mechanisms that lead to cell death remain unclear. METHODS In this study, we assessed the cell-killing potential of PDT using methylene blue (MB-PDT) in three breast epithelial cell lines that represent non-malignant conditions and different molecular subtypes of breast tumours. Cells were incubated in the absence or presence of MB and irradiated or not at 640 nm with 4.5 J/cm2. We used a combination of imaging and biochemistry approaches to assess the involvement of classical autophagic and apoptotic pathways in mediating the cell-deletion induced by MB-PDT. The role of these pathways was investigated using specific inhibitors, activators and gene silencing. RESULTS We observed that MB-PDT differentially induces massive cell death of tumour cells. Non-malignant cells were significantly more resistant to the therapy compared to malignant cells. Morphological and biochemical analysis of dying cells pointed to alternative mechanisms rather than classical apoptosis. MB-PDT-induced autophagy modulated cell viability depending on the cell model used. However, impairment of one of these pathways did not prevent the fatal destination of MB-PDT treated cells. Additionally, when using a physiological 3D culture model that recapitulates relevant features of normal and tumorous breast tissue morphology, we found that MB-PDT differential action in killing tumour cells was even higher than what was detected in 2D cultures. CONCLUSIONS Finally, our observations underscore the potential of MB-PDT as a highly efficient strategy which could use as a powerful adjunct therapy to surgery of breast tumours, and possibly other types of tumours, to safely increase the eradication rate of microscopic residual disease and thus minimizing the chance of both local and metastatic recurrence.

Abstract
The aim of the current study was to magnetically target the 5-fluorouracil (5-Fu) loaded magnetic poly lactic-co-glycolic acid (PLGA) nanocapsules towards CT26 colon tumor model in BALB/c mice. In addition, we ultrasonicated the tumors impregnated by nanocapsules with the goal of aiding them in magnetic drug targeting (MDT) procedure. Newly synthesized 5-Fu-loaded PLGA magnetic nanocapsules were characterized. Various treatment modalities with the use of nanocapsules, magnetic fields, and ultrasound were applied to the tumors and appropriate controls were considered. Magnetic resonance imaging (MRI) and Prussian blue (PB) staining were performed to analyze the distribution of nanocapsules within the CT26 tumor. Finally, anti-tumor and pro-apoptotic effects of each treatment modality on CT26 tumors were investigated. The effective diameter of nanocapsules was approximately 70 nm. The histological staining of the tumor tissue with PB as well as MRI revealed a broad distribution of magnetic nanocapsules within the tumor and confirmed the targeting of nanocapsules to the tumors. Anti-tumor studies demonstrated that the combination of nanocapsules-MDT-ultrasound effectively inhibits the growth of CT26 tumors compared with injection of 5-Fu alone (P < 0.01). The present study exhibits potentials of the newly synthesized magnetic nanocapsule and suggests that the combination of MDT and ultrasound might help this new nanotechnology-based cancer chemotherapy agent in vivo.

Abstract
BACKGROUND For decades, contrast agents have been used to reduce longitudinal (T1) or transverse (T2) relaxation times. High toxicity of gadolinium-based contrast agents leads researchers to new T1 contrast agents. Manganese oxide (MnO) nanoparticle (NP) with the lower peril and good enough signal change ability has been offered as a new possibility for magnetic resonance imaging (MRI). METHODS The synthesized NPs were investigated for physicochemical and biological properties by X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscope, dynamic light scattering (DLS), inductively coupled plasma, enzyme-linked immunosorbent assay, and 3T magnetic resonance imaging. RESULTS Due to physical contact importance of T1 contrast agents with tissues' protons, extremely thin layer of the surfactant, less than 2nm, was coated on NPs for aqueous stabilizing. The hydrophilic gentisic acid with low Dalton, around 154, did that role truly. Moreover, decreasing NP size to 5nm which increases available surface for the proton relaxation is another important parameter to reach an appropriate longitudinal relaxation rate. The NPs didn't reveal any side effects on the cells, and cellular uptake was considerable. CONCLUSIONS The synthesized NPs represented a promising result in comparison to clinical gadolinium chelates, due to higher r1 relaxivity and lower toxicity. GENERAL SIGNIFICANCE In addition to considerable signal change and cellular uptake, Prussian blue was tried on MnO NPs for the initial time, which can be observed within cells by pale blue color.

Abstract
Breast cancer, the most common type of cancer among women in the western world, affects approximately one out of every eight women over their lifetime. In recognition of the high invasiveness of surgical excision and severe side effects of chemical and radiation therapies, increasing efforts are made to seek minimally invasive modalities with fewer side effects. Nanoparticles (<100 nm in size) have shown promising capabilities for delivering targeted therapeutic drugs to cancer cells and confining the treatment mainly within tumors. Additionally, some nanoparticles exhibit distinct properties, such as conversion of photonic energy into heat, and these properties enable eradication of cancer cells. In this review, current utilization of nanostructures for cancer therapy, especially in minimally invasive therapy, is summarized with a particular interest in breast cancer.

Abstract
BACKGROUND Schistosomiasis is a neglected tropical disease with high morbidity and mortality in the world. Currently, the treatment of this disease depends almost exclusively on praziquantel (PZQ); however, the emergence of drug resistance to PZQ in schistosomes makes the development of novel drugs an urgent task. Aldose reductase (AR), an important component that may be involved in the schistosome antioxidant defense system, is predicted as a potential drug target. METHODS The tertiary structure of Schistosoma japonicum AR (SjAR) was obtained through X-ray diffraction method and then its potential inhibitors were identified from the Maybridge HitFinder library by virtual screening based on this structural model. The effects of these identified compounds on cultured adult worms were evaluated by observing mobility, morphological changes and mortality. To verify that SjAR was indeed the target of these identified compounds, their effects on recombinant SjAR (rSjAR) enzymatic activity were assessed. The cytotoxicity analysis was performed with three types of human cell lines using a Cell Counting Kit-8. RESULTS We firstly resolved the SjAR structure and identified 10 potential inhibitors based on this structural model. Further in vitro experiments showed that one of the compounds, renamed as AR9, exhibited significant inhibition in the activity of cultured worms as well as inhibition of enzymatic activity of rSjAR protein. Cytotoxicity analysis revealed that AR9 had relatively low toxicity towards host cells. CONCLUSIONS The work presented here bridges the gap between virtual screening and experimental validation, providing an effective and economical strategy for the development of new anti-parasitic drugs. Additionally, this study also found that AR9 may become a new potential lead compound for developing novel antischistosomal drugs against parasite AR.

Photosensitizing and radiosensitizing effects of mitoxantrone: combined chemo-, photo-, and radiotherapy of DFW human melanoma cells. Lasers Med Sci 2013; 28:1533-9. [PMID: 23371053 DOI: 10.1007/s10103-013-1275-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2012] [Accepted: 01/22/2013] [Indexed: 12/19/2022]
Abstract
This study evaluated the effects of mitoxantrone (MX), an antitumor agent, as a sensitizer to both photodynamic and radiation therapy in DFW human melanoma cells. Cells were incubated with MX at different concentrations for 90 min and then exposed to non-coherent light at different fluence rates and/or X-ray ionizing radiation at different dose rates. Combinatorial effects of this chemo-, photo-, and radiotherapy were also evaluated. MX had no significant effects on viability at moderate doses but had a strong cytotoxic effect on cancer cells when used as a photosensitizer. MX also acted as a potent radiosensitizer. We observed a dose-dependent effect on cell viability in cells exposed to MX in combination with phototherapy and radiotherapy. Strong synergistic effects were observed for combinations of two or more treatment methods, which, in some cases, induced complete cell death. Thus, a combination of ionizing radiation with MX-mediated photodynamic therapy could serve as a new method for cancer therapy with fewer adverse side effects.
