[PMID: 38612403 PMCID: PMC11011456 DOI: 10.3390/ijms25073590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 03/15/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024] Open
Abstract
Antimicrobial photodynamic inactivation (aPDI) is a method that specifically kills target cells by combining a photosensitizer and irradiation with light at the appropriate wavelength. The natural amino acid, 5-aminolevulinic acid (5-ALA), is the precursor of endogenous porphyrins in the heme biosynthesis pathway. This review summarizes the recent progress in understanding the biosynthetic pathways and regulatory mechanisms of 5-ALA synthesis in biological hosts. The effectiveness of 5-ALA-aPDI in destroying various groups of pathogens (viruses, fungi, yeasts, parasites) was presented, but greater attention was focused on the antibacterial activity of this technique. Finally, the clinical applications of 5-ALA in therapies using 5-ALA and visible light (treatment of ulcers and disinfection of dental canals) were described.

Abstract
β-phosphoglucomutase (βPGM) catalyzes the conversion of β-glucose 1-phosphate (βG1P) to glucose-6-phosphate (G6P), a universal source of cellular energy, in a two-step process. Transition state analogue (TSA) complexes formed from substrate analogues and a metal fluoride (MgF3- and AlF4-) enable analysis of each of these enzymatic steps independently. Novel substrate analogues incorporating fluorine offer opportunities to interrogate the enzyme mechanism using 19F NMR spectroscopy. Herein, the synthesis of a novel fluorinated phosphonyl C-glycoside (3-deoxy-3-fluoro-β-d-glucopyranosyl)methylphosphonate (1), in 12 steps (0.85 % overall yield) is disclosed. A four-stage synthetic strategy was employed, involving: 1) fluorine addition to the monosaccharide, 2) selective anomeric deprotection, 3) phosphonylation of the anomeric centre, and 4) global deprotection. Analysis of βPGM and 1 will be reported in due course.

Abstract
Recently, photodynamic therapy (PDT) has received a lot of attention for its potential use in cancer treatment. It enables the therapy of a multifocal disease with the least amount of tissue damage. The most widely used prodrug is 5-aminolevulinic acid, which undergoes heme pathway conversion to protoporphyrin IX, which acts as a photosensitizer (PS). Additionally, hematoporphyrin, bacteriochlorin, and phthalocyanine are also studied for their therapeutic potential in cancer. Unfortunately, not every patient who receives PDT experiences a full recovery. Resistance to different anticancer treatments is commonly observed. A few of the resistance mechanisms by which cancer cells escape therapeutics are genetic factors, drug-drug interactions, impaired DNA repair pathways, mutations related to inhibition of apoptosis, epigenetic pathways, etc. Recently, much research has been conducted to develop a new generation of PS based on nanomaterials that could be used to overcome cancer cells' multidrug resistance (MDR). Various metal-based, polymeric, lipidic nanoparticles (NPs), dendrimers, etc, have been utilized in the PDT application against cancer. This article discusses the detailed mechanism by which cancer cells evolve towards MDR as well as recent advances in PDT-based NPs for use against multidrug-resistant cancers.

JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2021; 221:112244. [PMID: 34174487 DOI: 10.1016/j.jphotobiol.2021.112244] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 06/03/2021] [Accepted: 06/16/2021] [Indexed: 01/10/2023]
Abstract
The delta-amino acid 5-aminolevulinic acid (ALA), is the precursor of the endogenous photosensitiser Protoporphyrin IX (PpIX), and is currently approved for Photodynamic Therapy (PDT) of certain superficial cancers. However, ALA-PDT is not very effective in diseases in which T-cells play a significant role. Cutaneous T-cell lymphomas (CTCL) is a group of non-Hodgkin malignant diseases, which includes mycosis fungoides (MF) and Sézary syndrome (SS). In previous work, we have designed new ALA esters synthesised by three-component Passerini reactions, and some of them showed higher performance as compared to ALA. This work aimed to determine the efficacy as pro-photosensitisers of five new ALA esters of 2-hydroxy-N-arylacetamides (1f, 1 g, 1 h, 1i and 1 k) of higher lipophilicity than ALA in Myla cells of MF and HuT-78 cells of SS. We have also tested its effectiveness against ALA and the already marketed ALA methyl ester (Me-ALA) and ALA hexyl ester (He-ALA). Both cell Myla and SS cells were effectively and equally photoinactivated by ALA-PDT. Besides, the concentration of ALA required to induce half the maximal porphyrin synthesis was 209 μM for Myla and 169 μM for HuT-78 cells. As a criterion of efficacy, we calculated the concentration of the ALA derivatives necessary to induce half the plateau porphyrin values obtained from ALA. These values were achieved at concentrations 4 and 12 times lower compared to ALA, according to the derivative used. For He-ALA, concentrations were 24 to 25 times lower than required for ALA for inducing comparable porphyrin synthesis in both CTCL cells. The light doses for inducing 50% of cell death (LD50) for He-ALA, 1f, 1 g, 1 h and 1i were around 18 and 25 J/cm2 for Myla and HuT-78 cells respectively, after exposure to 0.05 mM concentrations of the compounds. On the other hand, the LD50s for the compound 1 k were 40 and 57 J/cm2 for Myla and HuT-78, respectively. In contrast, 0.05 mM of ALA and Me-ALA did not provoke photokilling since the concentration employed was far below the porphyrin saturation point for these compounds. Our results suggest the potential use of ALA derivatives for topical application in PDT treatment of MF and extracorporeal PDT for the depletion of activated T-cells in SS.

JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2020; 215:112107. [PMID: 33401190 DOI: 10.1016/j.jphotobiol.2020.112107] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 11/19/2020] [Accepted: 12/17/2020] [Indexed: 12/29/2022]
Abstract
Photodynamic therapy (PDT) is a promising tumor therapy which utilizes reactive oxygen species (ROSs) to cause tumor cells death. 5-aminolevulinic acid (ALA) and two of its esters are FDA-approved photosensitizers. However, their clinical application suffers from their instability and lack of tumor selectivity. In addition, the overexpression of glutathione (GSH) in some tumor cells reduces the PDT efficiency due to the ROS-scavenging ability of GSH. In this work, we present three multifunctional ALA derivates with the characteristics of dual-targeting and GSH depletion to improve the therapeutic effect of ALA-based PDT. The general structure of these compounds consists of an ALA methyl ester (ALA-OMe) moiety that can metabolize to photosensitive protoporphyin IX (PpIX) inside the cells, a biotin group for targeting biotin receptor-positive tumor cells and a disulfide bond-based self-immolative linker which can be activated by GSH to liberate ALA-OMe. Simultaneously, the reaction between the disulfide bond and GSH also depletes intracellular GSH, causing tumor cells more vulnerable to ROSs. All three compounds exhibited high stability under physiological conditions. In vitro experiments demonstrated that the more lipophilic compounds 1 and 2 were much more efficient in inducing PpIX production in biotin receptor-overexpressed HeLa cells as compared with their parent compound (ALA-OMe). And the PpIX generation induced by compounds 1 and 2 was positively correlated with the overexpression of biotin receptor and GSH level in tumor cells. More importantly, the GSH depletion ability of them significantly increased their phototoxicity. Furthermore, in comparison with ALA-OMe, compound 2 showed much higher in vivo efficiency in PpIX production. All the results demonstrate that the combination strategy of dual-targeting and GSH depletion can be used to concurrently enhance the tumor-specificity and anti-tumor efficiency of ALA-based PDT. And this strategy may be used for designing other ALA-based photosensitizers with higher tumor-specificity and better therapeutic effects.

Abstract
Nanoparticles have been developed for tumor treatment due to the enhanced permeability and retention effects. However, lack of specific cancer cells selectivity results in low delivery efficiency and undesired side effects. In that case, the stimuli-responsive nanoparticles system designed for the specific structure and physicochemical properties of tumors have attracted more and more attention of researchers. Esterase-responsive nanoparticle system is widely used due to the overexpressed esterase in tumor cells. For a rational designed esterase-responsive nanoparticle, ester bonds and nanoparticle structures are the key characters. In this review, we overviewed the design of esterase-responsive nanoparticles, including ester bonds design and nano-structure design, and analyzed the fitness of each design for different application. In the end, the outlook of esterase-responsive nanoparticle is looking forward.

Abstract
5-Aminolevulinic acid (5-ALA) and its two ester derivatives (5-ALA-OMe and 5-ALA-OHex) have been approved for photodiagnosis and photodynamic therapy (PDT) of tumors in the clinical. However, their pharmacological activities are limited by their instability under physiological conditions and lack of tumor selectivity. With the aim to overcome these shortcomings, a glutathione-responsive 5-ALA derivative (SA) was designed based on the fact that many types of tumor cells have higher intracellular glutathione level than normal cells. SA was synthesized by masking the 5-amion group of 5-ALA methyl ester (5-ALA-OMe) with a self-immolative disulfide linker. Compared with 5-ALA and 5-ALA-OMe, SA exhibited higher stability under physiological conditions, and it can efficiently release the parent compound 5-ALA-OMe in response to glutathione. In tumor cells, SA displayed excellent protoporphyrin IX (PpIX) production activity at low concentrations while 5-ALA and 5-ALA-OMe were ineffective at the same concentration. The SA-induced PpIX production was positively correlated with the intracellular glutathione level, and SA exhibited enhanced phototoxicity due to its excellent PpIX generation activity. This study indicates that modification of the amino group in 5-ALA derivatives with a self-immolative disulfide linker is an effective strategy to improve their chemical stability and pharmacological activities, and SA is a potential photosensitizer for photodiagnosis and PDT of tumors.

Abstract
Galactose-modified thymidine, LNA-T, and 2'-amino-LNA-T nucleosides were synthesized, converted into the corresponding phosphoramidite derivatives and introduced into short oligonucleotides. Compared to the unmodified control strands, the galactose-modified oligonucleotides in general, and the N2'-functionalized 2'-amino-LNA derivatives in particular, showed improved duplex thermal stability against DNA and RNA complements and increased ability to discriminate mismatches. In addition, the 2'-amino-LNA-T derivatives induced remarkable 3'-exonuclease resistance. These results were further investigated using molecular modeling studies.

Abstract
A new method of synthesizing β-glycosyl esters stereospecifically has been developed by treating O-benzyl-protected glycosyl chlorides with Cs2CO3, tetrabutylammomium bromide (TBAB), a carboxylic acid, water, and granular polytetrafluoroethylene (PTFE) at 80 °C under mechanical agitation. D-Glucosyl, D-xylosyl, and D-galactosyl chlorides and 20 carboxylic acids were used to demonstrate the scope of the reaction. Control experiments showed that the water and granular PTFE had indispensable roles. Water-soluble TBAB has been found to be as efficient as N-methyl-N,N,N-trioctyloctan-1-ammonium chloride (Aliquat 336) in the reactions. After scaling up to 5-12 g, all of the products were obtained quantitatively via simple filtration and no organic solvents or chromatography was needed for the entire process.

Abstract
BACKGROUND Photodynamic therapy (PDT) with precursors of photoactivable porphyrins is a well-established treatment modality for skin pathologies as well as hair removal. Pain is a major side effect thereof, and it affects the treatment compliance and acceptance. METHODS Five male subjects underwent a PDT procedure on normal skin, either with a diode laser (635 nm) or a lamp (405 nm), 3 or 6h after application of various precursors of photoactivable porphyrins (ALA 1M; Metvix(®) 1M; ALA-DGME 1M; ALA-DGME 3.66 M). Light doses ranged from 30 to 150 J/cm(2) and irradiances were 100 or 180 mW/cm(2). Fluorescence measurements were performed just before PDT, pain was quantified during PDT, and erythema was determined 24h afterwards. RESULTS Because precursor ALA-DGME was very selective for the pilosebaceous apparatus vs. the epidermis, we solely carried out the PDTs using this precursor. In the absence of light, no pain was reported. An increase in pain was observed when increasing the irradiance. A correlation was observed between the follicular fluorescence and the maximal pain score during PDT. A correlation was observed between follicular fluorescence and skin erythema, and between pain score and skin erythema. CONCLUSIONS With our well-controlled PDT parameters and homogenous subjects' conditions, we showed that pain could be reduced by reducing irradiance during PDT procedures. With the various correlations observed, we conclude that both pain and PaP fluorescence are useful tools to predict the post-PDT tissue effects (side effects and outcome). We suggest that A∂ nerve fibres would be the best candidate as first generators of PDT-induced pain.

Abstract
In this paper, we discuss the evolution over the last 15 years in the Curie Institute of the concept, the development of the design and some properties of glycoconjugated photosensitizers with the aim to optimize the tumor targeting in photodynamic therapy. By this research, we have shown that specific interactions between a mannose-lectin and trimannosylglycodendrimeric porphyrins contributed to a larger extent than non-specific ones to the overall interaction of a glycosylated tetraarylporphyrin with a membrane. The studies of in vitro photocytotoxicity showed the relevance of the global geometry of the photosensitizer, the number and position of the linked glycopyranosyl groups on the chromophore and their lipophilicity. The two best compounds appeared to be porphyrins bearing three α-glycosyl groups on para-position of meso-phenyl via a flexible linker. Compound bearing α-manosyl moieties was evaluated successfully in two in vivo xenografted animal models of human retinoblastoma and colorectal cancers. Conversely, the presence on the chromophore of three sugars via a glycodendrimeric moiety induced a potential cluster effect, but decreased the in vitro photoefficiency despite a good affinity for a mannose-lectin.

Abstract
Exogenous 5-aminolevulinic acid (ALA) is taken up directly by bacteria, yeasts, fungi, and some parasites, which then induces the accumulation of protoporphyrin IX (PPIX). Subsequent light irradiation of PPIX leads to the inactivation of these organisms via photodamage to their cellular structures. ALA uptake and light irradiation of PPIX produced by host cells leads to the inactivation of other parasites, along with some viruses, via the induction of an immune response. ALA-mediated PPIX production by host cells and light irradiation result in the inactivation of other viruses via either the induction of a host cell response or direct photodynamic attack on viral particles. This ALA-mediated production of light-activated PPIX has been extensively used as a form of photodynamic therapy (PDT) and has shown varying levels of efficacy in treating conditions that are associated with microbial infection, ranging from acne and verrucae to leishmaniasis and onychomycosis. However, for the treatment of some of these conditions by ALA-based PDT, the role of an antimicrobial effect has been disputed and in general, the mechanisms by which the technique inactivates microbes are not well understood. In this study, we review current understanding of the antimicrobial mechanisms used by ALA-based PDT and its role in the treatment of microbial infections along with its potential medical and nonmedical applications.

Abstract
A set of molecules in which a glucose moiety is bound to a hydrogenable synthon has been synthesized and evaluated for hydrogenation reactions and for the corresponding para-hydrogen-induced polarization (PHIP) effects, in order to select suitable candidates for an in vivo magnetic resonance imaging (MRI) method for the assessment of glucose cellular uptake. It has been found that amidic derivatives do not yield any polarization enhancement, probably due to singlet-triplet state mixing along the reaction pathway. In contrast, ester derivatives are hydrogenated in high yield and afford enhanced (1)H and (13)C NMR spectra after para-hydrogenation. The obtained PHIP patterns are discussed and explained on the basis of the calculated spin level populations in the para-hydrogenated products. These molecules may find interesting applications in (13)C MRI as hyperpolarized probes for assessing the activity of glucose transporters in cells.

Abstract
Diruthenium tetracarbonyl complexes of the type [Ru2(CO)4(l2-g2-O2CR)2L2] containing a Ru-Ru backbone with four equatorial carbonyl ligands, two carboxylato bridges, and two axial two-electron ligands in a sawhorse-like geometry have been synthesized with porphyrin-derived substituents in the axial ligands [1: R is CH3, L is 5-(4-pyridyl)-10,15,20-triphenyl-21,23H-porphyrin], in the bridging carboxylato ligands [2: RCO2H is 5-(4-carboxyphenyl)-10,15,20-triphenyl-21,23H-porphyrin, L is PPh3; 3: RCO2H is 5-(4-carboxyphenyl)-10,15,20-triphenyl-21,23H-porphyrin, L is 1,3,5-triaza-7-phosphatricyclo [3.3.1.1]decane], or in both positions [4: RCO2H is 5-(4-carboxyphenyl)-10,15,20-triphenyl-21,23H-porphyrin, L is 5-(4-pyridyl)-10,15,20-triphenyl-21,23H-porphyrin]. Compounds 1-3 were assessed on different types of human cancer cells and normal cells. Their uptake by cells was quantified by fluorescence and checked by fluorescence microscopy. These compounds were taken up by human HeLa cervix and A2780 and Ovcar ovarian carcinoma cells but not by normal cells and other cancer cell lines (A549 pulmonary, Me300 melanoma, PC3 and LnCap prostate, KB head and neck, MDAMB231 and MCF7 breast, or HT29 colon cancer cells). The compounds demonstrated no cytotoxicity in the absence of laser irradiation but exhibited good phototoxicities in HeLa and A2780 cells when exposed to laser light at 652 nm, displaying an LD50 between 1.5 and 6.5 J/cm2 in these two cell lines and more than 15 J/cm2 for the others. Thus, these types of porphyric compound present specificity for cancer cell lines of the female reproductive system and not for normal cells; thus being promising new organometallic photosensitizers.

Abstract
Mononuclear 5-(4-pyridyl)-10,15,20-triphenylporphyrin and 5-(3-pyridyl)-10,15,20-triphenylporphyrin as well as tetranuclear 5,10,15,20-tetra(4-pyridyl)porphyrin (tetra-4-pp) and 5,10,15,20-tetra(3-pyridyl)porphyrin) (tetra-3-pp) arene ruthenium(II) derivatives (arene is C(6)H(5)Me or p-Pr(i)C(6)H(4)Me) were prepared and evaluated as potential dual photosensitizers and chemotherapeutics in human Me300 melanoma cells. In the absence of light, all tetranuclear complexes were cytotoxic (IC(50) < or = 20 microM), while the mononuclear derivatives were not (IC(50) > or = 100 microM). Kinetic studies of tritiated thymidine and tritiated leucine incorporations in cells exposed to a low concentration (5 microM) of tetranuclear p-cymene derivatives demonstrated a rapid inhibition of DNA synthesis, while protein synthesis was inhibited only later, suggesting arene ruthenium-DNA interactions as the initial cytotoxic process. All complexes exhibited phototoxicities toward melanoma cells when exposed to laser light of 652 nm. At low concentration (5 microM), LD(50) of the mononuclear derivatives was between 5 and 10 J/cm(2), while for the tetranuclear derivatives LD(50) was approximately 2.5 J/cm(2) for the [Ru(4)(eta(6)-arene)(4)(tetra-4-pp)Cl(8)] complexes and less than 0.5 J/cm(2) for the [Ru(4)(eta(6)-arene)(4)(tetra-3-pp)Cl(8)] complexes. Examination of cells under a fluorescence microscope revealed the [Ru(4)(eta(6)-arene)(4)(tetra-4-pp)Cl(8)] complexes as cytoplasmic aggregates, whereas the [Ru(4)(eta(6)-arene)(4)(tetra-3-pp)Cl(8)] complexes were homogenously dispersed in the cytoplasm. Thus, these complexes present a dual synergistic effect with good properties of both the arene ruthenium chemotherapeutics and the porphyrin photosensitizer.

Abstract
5-Aminolevulinic acid (ALA) and derivatives thereof have been successfully used in photodynamic cancer therapy (PDT). The synthesis of novel bioconjugates combining ALA with two lipophilic and one hydrophilic vitamins is reported. The new bioconjugates allow studying the potential synergies between the two components in PDT. The synthetic methodology is robust giving the bioconjugates in good to satisfactory yield.
