Abstract
In the process of finding better therapeutics, thousands of new molecules are synthesised every day. Many of these can be poorly soluble in water, leading to a potentially promising drug being rejected during testing due to its poor solubility. Polyethylene glycol (PEG) has become known as an excellent modification to remedy this and was initially used to increase circulation time and reduce the immunogenicity of therapeutic proteins. Thus significantly increasing their safety and range of use. Another group of compounds in which significant benefits of pegylation have been seen are photosensitisers. Used in photodynamic therapy, they are often characterised by very high hydrophobicity. Pegylation of their structure significantly increases their affinity for cancer cells and facilitates their penetration through cell membranes. Classical small-molecule drugs can benefit from temporary combinations hydrolysed in the body or very short PEG chains. This approach allows a significant increase in the bioavailability of the drug while avoiding the disadvantages of small molecule pegylation. However, the most common motive for pegylation recently is the creation of drug carriers. Liposomes and nanoparticles make it possible to exploit the advantages of PEG to stabilise their structure and increase circulation time while not modifying the structure of the active compound. Unfortunately, PEGs also have their drawbacks. The first is their high molecular weight range, especially for longer chains, which poses difficulties in purification. Another is the emergence of antibodies directed against PEG. Nevertheless, pegylation is still an up-and-coming method for modifying pharmaceutically active molecules.

Novel Short PEG Chain-Substituted Porphyrins: Synthesis, Photochemistry, and In Vitro Photodynamic Activity against Cancer Cells. Int J Mol Sci 2022; 23:ijms231710029. [PMID: 36077451 PMCID: PMC9456001 DOI: 10.3390/ijms231710029] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 08/15/2022] [Accepted: 08/26/2022] [Indexed: 11/16/2022] Open
Abstract
This work presents the synthesis and characterization of metal-free, zinc (II), and cobalt (II) porphyrins substituted with short PEG chains. The synthesized compounds were characterized by UV-Vis, 1H and 13C NMR spectroscopy, and MALDI-TOF mass spectrometry. The origin of the absorption bands for tested compounds in the UV-Vis range was determined using a computational model based on the electron density functional theory (DFT) and its time-dependent variant (TD-DFT). The photosensitizing activity was evaluated by measuring the ability to generate singlet oxygen (ΦΔ), which reached values up to 0.54. The photodynamic activity was tested using bladder (5637), prostate (LNCaP), and melanoma (A375) cancer cell lines. In vitro experiments clearly showed the structure-activity relationship regarding types of substituents, their positions in the phenyl ring, and the variety of central metal ions on the porphyrin core. Notably, the metal-free derivative 3 and its zinc derivative 6 exerted strong cytotoxic activity toward 5637 cells, with IC50 values of 8 and 15 nM, respectively. None of the tested compounds induced a cytotoxic effect without irradiation. In conclusion, these results highlight the potential value of the tested compounds for PDT application.

Abstract
Urological cancers are among the most common malignancies around the world. In particular, bladder cancer severely threatens human health due to its aggressive and heterogeneous nature. Various therapeutic modalities have been considered for the treatment of bladder cancer although its prognosis remains unfavorable. It is perceived that treatment of bladder cancer depends on an interdisciplinary approach combining biology and engineering. The nanotechnological approaches have been introduced in the treatment of various cancers, especially bladder cancer. The current review aims to emphasize and highlight possible applications of nanomedicine in eradication of bladder tumor. Nanoparticles can improve efficacy of drugs in bladder cancer therapy through elevating their bioavailability. The potential of genetic tools such as siRNA and miRNA in gene expression regulation can be boosted using nanostructures by facilitating their internalization and accumulation at tumor sites and cells. Nanoparticles can provide photodynamic and photothermal therapy for ROS overgeneration and hyperthermia, respectively, in the suppression of bladder cancer. Furthermore, remodeling of tumor microenvironment and infiltration of immune cells for the purpose of immunotherapy are achieved through cargo-loaded nanocarriers. Nanocarriers are mainly internalized in bladder tumor cells by endocytosis, and proper design of smart nanoparticles such as pH-, redox-, and light-responsive nanocarriers is of importance for targeted tumor therapy. Bladder cancer biomarkers can be detected using nanoparticles for timely diagnosis of patients. Based on their accumulation at the tumor site, they can be employed for tumor imaging. The clinical translation and challenges are also covered in current review.

Abstract
Photodynamic therapy (PDT) is a potential non-invasive approach for application in oncological diseases, based on the activation of a photosensitizer (PS) by light at a specific wavelength in the presence of molecular oxygen to produce reactive oxygen species (ROS) that trigger the death tumor cells. In this context, porphyrins are interesting PS because they are robust, have high chemical, photo, thermal, and oxidative stability, and can generate singlet oxygen (1O2). However, porphyrins exhibit low solubility and a strong tendency to aggregate in a biological environment which limits their clinical application. To overcome these challenges, we developed hybrid nanostructures to immobilize 5,10,15,20-tetrakis[(4-carboxyphenyl) thio-2,3,5,6-tetrafluorophenyl] (P), a new third-generation PS. The biological effect of this system was evaluated against bladder cancer (BC) cells with or without light exposition. The nanostructure composed of lipid carriers coated by porphyrin-chitosan (P-HNP), presented a size of ca. 130 nm and low polydispersity (ca. 0.25). The presence of the porphyrin-chitosan (P-chitosan) on lipid nanoparticle surfaces increased the nanoparticle size, changed the zeta potential to positive, decreased the recrystallization index, and increased the thermal stability of nanoparticles. Furthermore, P-chitosan incorporation on nanoparticles increased the stability and enhanced the self-organization of the system and the formation of spherical structures, as observed by small-angle X-ray scattering (SAXS) analysis. Furthermore, the immobilization process maintained the P photoactivity and improved the photophysical properties of PS, minimizing its aggregation in the cell culture medium. In the photoinduction assays, the P-HNP displayed high phototoxicity with IC50 3.2-folds lower than free porphyrin. This higher cytotoxic effect can be correlated to the high cellular uptake of porphyrin immobilized, as observed by confocal images. Moreover, the coated nanoparticles showed mucoadhesive properties interesting to its application in vivo. Therefore, the physical and chemical properties of nanoparticles may be relevant to improve the porphyrin photodynamic activity in BC cells.

Abstract
This review arises from the need to rationalize the huge amount of information on the structural and spectroscopic properties of a peculiar class of porphyrin derivatives-the non-ionic PEGylated porphyrins-collected during almost two decades of research. The lack of charged groups in the molecular architecture of these porphyrin derivatives is the leitmotif of the work and plays an outstanding role in highlighting those interactions between porphyrins, or between porphyrins and target molecules (e.g., hydrophobic-, hydrogen bond related-, and coordination-interactions, to name just a few) that are often masked by stronger electrostatic contributions. In addition, it is exactly these weaker interactions between porphyrins that make the aggregated forms more prone to couple efficiently with external perturbative fields like weak hydrodynamic vortexes or temperature gradients. In the absence of charge, solubility in water is very often achieved by covalent functionalization of the porphyrin ring with polyethylene glycol chains. Various modifications, including of chain length or the number of chains, the presence of a metal atom in the porphyrin core, or having two or more porphyrin rings in the molecular architecture, result in a wide range of properties. These encompass self-assembly with different aggregate morphology, molecular recognition of biomolecules, and different photophysical responses, which can be translated into numerous promising applications in the sensing and biomedical field, based on turn-on/turn-off fluorescence and on photogeneration of radical species.

Drug delivery systems for the photodynamic application of two photosensitizers belonging to the porphyrin family. Photochem Photobiol Sci 2021; 20:1011-1025.

Abstract
Photodynamic therapy involves the concomitant action of three components, light with an appropriate wavelength, molecular oxygen, and a molecule, able to absorb an electromagnetic radiation, called photosensitizer (PS). A fundamental aspect is the bioavailability of the PS that is directly related to some physicochemical properties of the PS itself as it should feature a certain degree of lipophilicity to easily cross the cell membrane, however, at the same time, should be sufficiently water-soluble to navigate in the bloodstream. Consequently, the use of a system for drug delivery becomes essential when photosensitizers with a high degree of lipophilicity are considered. In this work, we present three different drug delivery systems, microemulsions, emulsions and liposomes all capable of carrying a PS belonging to the porphyrin family: the tetraphenyl porphyrin (TPP) and the 4-hydroxyphenyl porphyrin (THPP), which show a relevant different degree of lipophilicity. A series of microemulsions (ME) and emulsions (E) were prepared, among which two formulations, one for THPP and one for TPP, have been chosen. The stability of these two carriers was monitored over time and under various temperature conditions. With the same criteria, two liposomal formulations have been also identified and analyzed. The four formulations mentioned above (one ME, one E and two liposomes) have been tested on SKOV3 tumor cell line comparing the photodynamic activity of the porphyrin formulations versus the aqueous/organic (DMSO) solution of the same two PSs. The results show that all the formulations have proved to be excellent carriers and that the liposomal formulation enhance the photodynamic efficacy of both porphyrins.

Abstract
Although photodynamic therapy (PDT) is an effective, minimally invasive therapeutic modality with advantages in highly localized and specific tumor treatments, large and deep-seated cancers within the body cannot be successfully treated due to low transparency to visible light. To improve the therapeutic efficiency of tumor treatment in deep tissue and reduce the side effects in normal tissue, this study developed a near-infrared (NIR)-triggered upconversion nanoparticle (UCNP)-based photosensitizer (PS) carrier as a new theranostics system. The NaYF4:Yb/Er UCNPs were synthesized by a hydrothermal method, producing nanoparticles of a uniformly small size (≈20 nm) and crystalline morphology of the hexagonal phase. These UCNPs were modified with folic acid-conjugated biocompatible block copolymers through a bidentate dihydrolipoic acid linker. The polymer modified hexagonal phase UCNPs (FA-PEAH-UCNPs) showed an improved dispersibility in the aqueous solution and strong NIR-to-vis upconversion fluorescence. The hydrophobic PS, pheophorbide a (Pha), was then conjugated to the stable vectors. Moreover, these UCNP-based Pha carriers containing tumor targeting folic acid ligands exhibited the significantly enhanced cellular uptake efficiency as well as PDT treatment efficiency. These results suggested that this system could extend the excitation wavelength of PDT to the NIR region and effectively improve therapeutic efficiency of PSs.

Photodynamic therapy (PDT) is a modality of cancer treatment in which tumor cells are destroyed by reactive oxygen species (ROS) produced by photosensitizers following its activation with visible or near infrared light. The PDT success is dependent on different factors namely on the efficiency of the photosensitizer deliver and targeting ability. In this review a special attention will be given to the role of some drug delivery systems to improve the efficiency of tetrapyrrolic photosensitizers to this type of treatment.

Abstract
Photodynamic therapy is a minimally invasive and promising new method in cancer treatment and has attracted considerable attention in recent years. An ideal photosensitizer is a crucial element to photodynamic therapy. In the present paper, a novel porphyrin derivative, 5, 10, 15, 20-tetrakis (5-(pyrrolidin-1-yl) pentyl) porphin (TPPP) was synthesized. Its spectroscopic and physicochemical properties, therapeutic efficacy as a photosensitizer in photodynamic therapy for human bladder cancer in vitro and in vivo were investigated. TPPP had strong absorption at 648nm (ε=1.75×10(4)M(-1)cm(-1)), and two fluorescence emission peaks at 652nm and 718nm. PDT with TPPP showed low dark toxicity and high phototoxicity to human bladder cancer T24 cells in vitro. In bearing T24 tumor nude mice, the growth of tumor was significantly inhibited by combining use of 5mg/kg TPPP with 100J/cm(2) (650nm, 180mW/cm(2)) laser irradiation at 3h following injection of TPPP. The antitumor effect was also confirmed with histopathological assay. The histopathological study results revealed that PDT using TPPP and 100J/cm(2) (650nm, 180mW/cm(2)) laser irradiation induced tumor cells shrunken and necrotic. These results indicate that TPPP is useful as a new photosensitizer in PDT for cancer, and deserves further investigation.

Abstract
Porphyrin derivatives for photodynamic therapy are frequently modified with hydrophilic groups to improve their water solubility; however, such hydrophilic groups not only improve the solubility but also affect the photodynamic behavior of the compound. The suitable number and pattern of the hydrophilic substituents depend on the nature of the hydrophilic groups. In this article, we explore the optimum architecture for 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin (TFPP) derivatives bearing 2-hydroxyethylthio substituents. All five derivatives, namely mono-, cis-bis-, trans-bis-, tris- and tetrakis-substituted TFPP, were successfully synthesized by the nucleophilic aromatic substitution of TFPP with 2-hydroxyethanethiol, separated, and subsequently identified using ESI-TOF mass spectrometry and (1)H and (19)F NMR spectroscopies. The hydrophilicity of the compounds increased with an increase in the number of 2-hydroxyethylthio groups. The singlet oxygen and hydroxyl radical generation efficiencies were estimated using chemical probes following photoirradiation (λ>500nm). trans-Bissubstituted TFPP exhibited the highest efficiency for both singlet oxygen and hydroxyl radical generation. The photocytotoxicities of the photosensitizers were evaluated in HeLa cells following photoirradiation (λ>500nm, 16Jcm(-2)), and increased with an increase in number of 2-hydroxyethylthio groups. In the case of 2-hydroxyethylthio-substituted TFPPs, the fully substituted TFPP was the most efficient architecture plausibly because of the result of the hydrophilicity of the compound rather than a greater efficiency in the generation of reactive oxygen species.

Abstract
Synthetic lipids and surfactants that do not exist in biological systems have been used for the last few decades in both basic and applied science. The most notable applications for synthetic lipids and surfactants are drug delivery, gene transfection, as reporting molecules, and as support for structural lipid biology. In this review, we describe the potential of the synergistic combination of computational and experimental methodologies to study the behavior of synthetic lipids and surfactants embedded in lipid membranes and liposomes. We focused on select cases in which molecular dynamics simulations were used to complement experimental studies aiming to understand the structure and properties of new compounds at the atomistic level. We also describe cases in which molecular dynamics simulations were used to design new synthetic lipids and surfactants, as well as emerging fields for the application of these compounds. This article is part of a Special Issue entitled: Biosimulations edited by Ilpo Vattulainen and Tomasz Róg.

Abstract
In this study, we developed and investigated nanoparticles of biologically-derived, biodegradable polyhydroxyalkanoates (PHAs) as carriers of a hydrophobic photosensitizer, 5,10,15,20-Tetrakis(4-hydroxy-phenyl)-21H, 23H-porphine (pTHPP) for photodynamic therapy (PDT). Three PHA variants; polyhydroxybutyrate, poly(hydroxybutyrate-co-hydroxyvalerate) or P(HB-HV) with 12 and 50% HV were used to formulate pTHPP-loaded PHA nanoparticles by an emulsification-diffusion method, where we compared two different poly(vinyl alcohol) (PVA) stabilizers. The nanoparticles exhibited nano-scale spherical morphology under TEM and hydrodynamic diameters ranging from 169.0 to 211.2 nm with narrow size distribution. The amount of drug loaded and the drug entrapment efficiency were also investigated. The in vitro photocytotoxicity was evaluated using human colon adenocarcinoma cell line HT-29 and revealed time and concentration dependent cell death, consistent with a gradual release pattern of pTHPP over 24 h. This study is the first demonstration using bacterially derived P(HB-HV) copolymers for nanoparticle delivery of a hydrophobic photosensitizer drug and their potential application in PDT.

Abstract
Photodynamic therapy (PDT) is a non-invasive combinatorial therapeutic modality using light, photosensitizer (PS), and oxygen used for the treatment of cancer and other diseases. When PSs in cells are exposed to specific wavelengths of light, they are transformed from the singlet ground state (S₀) to an excited singlet state (S₁-Sn), followed by intersystem crossing to an excited triplet state (T₁). The energy transferred from T₁ to biological substrates and molecular oxygen, via type I and II reactions, generates reactive oxygen species, (¹O₂, H₂O₂, O₂*, HO*), which causes cellular damage that leads to tumor cell death through necrosis or apoptosis. The solubility, selectivity, and targeting of photosensitizers are important factors that must be considered in PDT. Nano-formulating PSs with organic and inorganic nanoparticles poses as potential strategy to satisfy the requirements of an ideal PDT system. In this review, we summarize several organic and inorganic PS carriers that have been studied to enhance the efficacy of photodynamic therapy against cancer.

Abstract
The cell-based studies of 5, 10, 15, 20-Tetrakis (4-amidinophenyl) porphyrin (Por1), its Zn complex (Por2) and amidinophenyl bisporphyrin (Por3) were carried out to examine their photocytotoxicity, cellular uptake and sub-cellular localization with human nasopharyngeal carcinoma cell (HK-1), using 5, 10, 15, 20-Tetrakis (N-methyl-4-pyridyl) porphyrin (H2TMPyP) as a reference. These porphyrins showed low dark-cytotoxicity and high photo-cytotoxicity against HK-1. The amphiphilic amidinophenyl bisporphyrin (Por3) displayed better cellular uptake than the single hydrophilic Por1, Por2 and H2TMPyP. As seen from the extent of overlapping of the fluorescence profiles, lysosomal localization of amidinophenylporphyrin Por1-Por3 and mito/lyso localization of the H2TMPyP occurred in the cells. The results suggest these porphyrins with amidine group could be used as potential agents in photodynamic therapy.

Abstract
Multifunctional nanomedicine holds considerable promise as the next generation of medicine that will enable early detection of diseases, as well as simultaneous monitoring and therapy with minimal toxicity. In particular, surface-enhanced Raman scattering (SERS) technology with high sensitivity and multiplexing capabilities is emerging as a powerful alternative for identifying specific biological targets in live cells. In this paper, we present the synthesis of SERS-active gold nanochains (AuNCs) as a potential theranostic system for multiplex detection and photodynamic therapy (PDT) of cancer. AuNCs were prepared by a simple physical mixing method to assemble citrate-stabilized gold nanoparticles into nanochains using hyaluronic acid and hydrocaffeic acid (HA-HCA) conjugates as templates. In addition, Raman reporters and photosensitizers (PSs) were conjugated onto the surface of the AuNCs for multiplex detection and PDT action. After mixing with HA-HCA conjugates, citrate-stabilized gold nanoparticles formed the AuNC structure, and AuNC length was controlled by the HCA conjugation ratio in the HA-HCA conjugates. AuNCs exhibited maximal absorption in the near-infrared (NIR) spectral region and effective SERS property. Confocal microscopy, flow cytometry, Raman spectroscopy and Bio-TEM measurements were used to determine cellular uptake of the Raman reporter, PS and AuNCs in HeLa cells. AuNCs conjugated with Raman reporter and PS (HA-HCAn-Au-Pheo-NPT) showed more than 99% cellular uptake and exhibited excellent phototoxicity even at low PS concentrations compared with free PS after laser irradiation. This SERS-active AuNC (HA-HCAn-Au-Pheo-NPT) shows promise for applications in theranostics, integrating SERS imaging and PDT.

Abstract
The complete eradication of various targets, such as infectious agents or cancer cells, while leaving healthy host cells untouched, is still a great challenge faced in the field of medicine. Photodynamic therapy (PDT) seems to be a promising approach for anticancer treatment, as well as to combat various dermatologic and ophthalmic diseases and microbial infections. The application of liposomes as delivery systems for porphyrinoids has helped overcome many drawbacks of conventional photosensitizers and facilitated the development of novel effective photosensitizers that can be encapsulated in liposomes. The development, preclinical studies and future directions for liposomal delivery of conventional and novel photosensitizers are reviewed.

Abstract
An effective tumor-targeted drug delivery system for photodynamic therapy was developed by designing ligand-mediated nanoparticles with stable formulations of a hydrophobic photosensitizer. Novel folic acid (FA)-conjugated amphiphilic block copolymers of polyethylene glycol (PEG) and poly-β-benzyl-L-aspartate (PBLA) with the potential to act as pH-responsive drug release reservoirs were synthesized. The photosensitizer, 2,4-diacetyl deuteroporphyrin IX dimethyl ether (DD-PpIX), was conjugated to the copolymers through pH-sensitive hydrazone linkage. The syntheses and compositions of all copolymers were confirmed by 1H NMR measurement. Photosensitizer-conjugated amphiphilic copolymeric nanoparticles (FA-PEG-P(Asp-Hyd)-DD-PpIX) were prepared by micelle formation in aqueous solution. The particle sizes of the FA-PEG-PBLA and FA-PEG-P(Asp-Hyd)-DD-PpIX nanoparticles were determined by light-scattering measurements. The range was 105–298 nm, depending on copolymer molecular weight and composition. Field emission scanning electron microscopy showed that the FA-PEG-P(Asp-Hyd)-DD-PpIX copolymeric nanoparticles were submicron in size and spherical in shape. The results of in vitro release tests showed that the release profiles of DD-PpIX from the nanoparticles were strongly pH-dependent and influenced by the amount of photosensitizer that was conjugated. In vitro tests using HeLa cells indicated that the FA-PEG-P(Asp-Hyd)-DD-PpIX nanoparticles had low dark-toxicity and showed more than 97% of cellular uptake. Based on our results, the FA-PEG-P(Asp-Hyd)-DD-PpIX nanoparticle system could be a promising approach for developing novel photosensitizer delivery carriers for photodynamic therapy.

Abstract
Photosensitizing properties of 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin (p-THPP) functionalized by covalent attachment of one chain of poly(ethylene glycol) (PEG) with a molecular weight of 350, 2000, or 5000 Da (p-THPP-PEG(350), p-THPP-PEG(2000), p-THPP-PEG(5000)) were studied in vitro. Dark and photo cytotoxicity of these photosensitizers delivered in solution or embedded in liposomes were evaluated on two cell lines: a human colorectal carcinoma cell line (HCT 116) and a prostate cancer cell line (DU 145), and compared with these treated with free p-THPP. The attachment of PEG chains results in the pronounced reduction of the dark cytotoxicity of the parent porphyrin. Cell viability tests have demonstrated that the phototoxicity of pegylated porphyrins is dependent on the length of PEG chain and p-THPP-PEG(2000) exhibited the highest photodynamic efficacy for both cell lines. The encapsulation into liposomes did not improve the PDT effect. However, the liposomal formulation of p-THPP-PEG(2000) showed a greater tendency to induce apoptosis in both cell lines than the parent or pegylated porphyrin delivered in solution. The colocalization of p-THPP, p-THPP-PEG(2000) and p-THPP-PEG(2000) enclosed in liposomes with fluorescent markers for lysosomes, mitochondria, endoplasmatic reticulum (ER) and Golgi apparatus (GA) was determined in the HCT 116 line. The p-THPP exhibited ubiquitous intracellular distribution with a preference for membranes: mitochondria, ER, GA, lysosomes and plasma membrane. Fluorescence of p-THPP-PEG(2000) was observed within the cytoplasm, with a stronger signal detected in membranous organelle: mitochondria, ER, GA and lysosomes. In contrast, p-THPP-PEG(2000) delivered in liposomes gave a distinct lysosomal pattern of localization.
