Abstract :

Phthalocyanines (Pcs) are considered promising in cancer phototherapy. However, their maximum absorption wavelengths are only around 700 nm, which cannot allow deep tissue penetration and leads to poor therapeutic efficacy. To expand their clinical application, significantly shifting their absorption to longer wavelengths is urgently required. Dye J-aggregates exhibit a redshifted absorption relative to its monomer. However, Pc J-aggregates with enormous-redshifted and intense absorption is rarely reported, and little is known about the relationships between Pc structure and J-aggregation. Herein, such Pc J-aggregates are ingeniously conceived. With a yeast β-D-glucan-ursodeoxycholic acid conjugate as a potential tumor-associated macrophages (TAMs)-targeting carrier and 1-(4-carboxyethylphenoxy) zinc (II) phthalocyanine (Pc1) as a model, Pc1 J-aggregate nanoparticle (NanoPc1) is obtained via ultrasonication-aided emulsification-solvent evaporation technique. NanoPc1 displays strong absorption at 830 nm, with a 156 nm redshift. Further investigation on another twenty-four Pcs demonstrates that unsubstituted zinc (II) or magnesium (II) Pc and hydrophobic mono-substituted zinc (II) or magnesium (II) Pcs with mono-substituted phenoxy or phenylthio or naphthoxy as a substituent can readily form desired Pc J-aggregates with significant redshifts (140–165 nm). The other Pcs fail to form expected J-aggregates probably due to absence of central metals, steric hindrance on central metals (atoms), forming axial coordination on central metals, disorder tendency during self-assembly or hydrophilicity. The theoretical calculation indicates that Pc1 in its J-aggregates exhibits a spiral-like arrangement, and the reduction in the energy gap between HOMO and LUMO and variation of intermolecular π-π interaction caused by J-aggregate formation are responsible for the huge redshift. Additionally, using NanoPc1 as an exemplar, such Pc J-aggregate nanoparticles are substantiated to afford TAMs-targeted and efficient tri-modal imaging and photothermal therapy in a H22 mouse model. © 2024 Elsevier B.V.

Abstract :

The weakness of visible and near-infrared light penetration depth limits the application of photodynamic therapy (PDT) in deep-seated tumors. Based on the high penetrability of X-rays, X-ray-induced PDT (X-PDT) is a promising new method for treating deep-seated tumors. However, it requires the development of suitable X-ray-induced sensitizers that could employ X-ray energy to produce reactive oxygen species (ROS) efficiently. In this study, a novel X-ray-induced sensitizer (NanoSRF) was developed through a microemulsion method, in which copper iodine cluster compound Cu2I2(tpp)2(2,5-dm-pz) (CIP) and rose bengal (RB) worked as scintillator and photosensitizer, respectively. CIP was synthesized by a simple mechanical grinding method, and subsequently folic acid (FA)-modified albumin was introduced to enable its alliance with RB. NanoSRF exhibited excellent dispersion stability and generated a large amount of ROS under X-ray irradiation. The results of in vitro studies demonstrated its high selectivity for FA receptor-positive cancer cells. Following systemic administration, NanoSRF accumulated in H22 tumors of xenograft-bearing mice, and X-ray irradiation (5.46 Gy) induced a significant inhibition rate of 96.7% in tumor growth. This study pioneers the use of copper iodide cluster as a scintillator in X-PDT, presenting new possibilities for designing scintillators with exceptional X-ray absorption and efficient X-PDT capabilities.

Abstract :

With a view to developing highly efficient photosensitizers for photodynamic therapy, herein, we prepared a series of tetra-substituted zinc(II) phthalocyanine analogues (ZPOP, ZPSP, ZPNP, and ZPNPM) modified with O-, S-, and N-bridging substituents, respectively. Compared to O- and S-bridging analogues, the N-bridging phthalocyanines showed eminent red-shifted Q band absorption (750-780 nm) and excellent reactive oxygen species (ROS) generation ability (Phi Delta = 0.90-0.97), due to the HOMO destabilization, as well as the smaller Delta EST. To improve the hydrophility and biocompatibility, we further prepared two N-bridging zinc(II) phthalocyanines (ZPN1 and ZPN2) modified with morpholine and N,N-dimethylamine moieties, respectively, along with their quaternized counterparts (QZPN1 and QZPN2). These compounds exhibited NIR-absorbing Q bands at 774-777 nm and efficient ROS generation ability in aqueous solutions, especially formulated with 1 % Cremophor EL (Cel). In vitro studies indicated that ZPN2 exhibited the highest photodynamic activity against HepG2 cells (IC50 = 0.44 +/- 0.02 mu M), because of superior cellular uptake and moderate ROS generation ability. Moreover, ZPN2 could selectively accumulate and retain in tumor tissue of H22 tumor-bearing mice. The work presents a new strategy for the development of NIR-absorbing photosensitizers.

Abstract :

A series of alpha-tetra-substituted phthalocyanines (M = 2H, Cu, Co, Ni) with morpholinyl moieties and their corresponding quaternized derivatives have been synthesized. The spectroscopic and photosensitizing properties, photothermal effects, aggregation trend, and partition coefficients of these phthalocyanines are evaluated. Besides, we appraised their photothermal and photodynamic activities against C. albicans and E. coli under nearinfrared (NIR) light irradiation (680 nm). The results show that cationic phthalocyanines are more efficacies in killing bacteria and fungi than their neutral analogues. For copper (II) phthalocyanine 4b and metal-free phthalocyanine 7b, their photodynamic activities play a key role in antimicrobial treatment, while for other phthalocyanines, their photothermal effects play a major role. Moreover, metal-free phthalocyanine 7b exhibits an ideal synergistic photothermal/photodynamic antimicrobial activity and shows the highest photocytotoxicity among all the compounds. The IC90 values of 7b towards C. albicans and E. coli are as low as 1.12 mu M and 0.47 mu M, respectively, while others have IC90 values ranging from 3.31 mu M to 50 mu M, implying that 7b would be a good candidate for future antimicrobial applications.

Abstract :

In order to reduce the intramolecular charge-transfer (ICT) effect of amine groups on the photophysical properties of zinc (II) phthalocyanine (ZnPc), tertiary amines were covalently connected with ZnPc ring via ethyl phydroxybenzoate or diethyl 5-hydroxyisophthalate. Six new tertiary amine-modified ZnPcs were therefore synthesized and characterized. Meanwhile, the corresponding quaternary ammonium ZnPcs were also synthesized. The effects of different substitution ways (mono-substitutions, symmetrical tetra-substitutions, or asymmetric tetra-substitutions) and the numbers of different substitutions on the photophysical and physicochemical properties of these ZnPcs were studied. All twelve ZnPcs had relatively high singlet oxygen quantum yields (& phi;& UDelta; = 0.32-0.68) and fluorescence quantum yields (& phi;F = 0.23-0.40), where the amine-containing substituents did not show obvious ICT effect. All ZnPcs showed effective phototoxicity towards breast cancer cells (IC50 = 63-366 nmol/L). Among them, three tetra-substituted ZnPcs containing quaternary ammonium groups (4aN, 4bN and 4cN) showed the best in vitro anticancer photodynamic activities with IC50 = 64-76 nmol/L, which owned to their relatively high cellular uptake. The tumor inhibition rate of 4aN on H22 tumor-bearing mice reached 87% (4aN dose: 3 nmol/g; light dose: 685 nm, 135 J/cm2).

Abstract :

Photothermal therapy (PTT) possesses a great promise for tumor therapy due to its effective tumor inhibition and minimal invasiveness. Nevertheless, most of organic photothermal agents (PTAs) suffer from poor photothermal conversion efficiency, and the residues of PTAs may cause the problem of side effects. Herein, we utilize a molecular surgery approach to develop a self-degradable nanostructured PTA (NanoPcDA2). NanoPcDA2 exhibited a remarkable photothermal conversion efficiency. In addition, NanoPcDA2 showed an outstanding tumor accumulation after intravenous injection, and 92% tumor growth was suppressed in the mice tumor model at a low light dose of 300 J cm(-2) and a NanoPcDA2 dose of 0.8 nmol g(-1). Moreover, NanoPcDA2 can be degraded by singlet oxygen (O-1(2)) produced by itself and lose its photoactivity after PTT. Notably, the photodegradation products of NanoPcDA2 have negligible cytotoxicity. In this way, it not only contributes to resolve the potential phototoxicity problems of residual PTAs, but also can expedite the metabolism of PTAs to avert the potential biotoxicity of drug accumulation.

Abstract :

Although specific responsive theranostics biomaterials were essencial for precision medicine, the univariate responsive strategy was restricted by high false-positive rates. Herein, we designed a novel phthalocyanine-iron-based complex FeS2@PcD, as a theranostics nanoreactor, which was program-regulated by bivariate factors of H+ and H2O2 in tumor microenvironment (TME). We found that FeS2@PcD had the excellent capability of tumor fluorescence imaging (FLI), with a 52.21-fold increase in fluorescence signal by the programmable response, while the signal of the univariate factor was almost unchanged. We also revealed that FeS2@PcD reacted with H+ to release PcD and produced Fe2+, then Fe2+ was further oxidized by H2O2 to produce Fe3+, finally recovering the fluorescence of PcD whose fluorescence activity was significantly suppressed due to the photoinduced electron transfer (PET) effect. Notably, except for fluorescence signal, magnetic resonance (MR) signal and sonosensitive activity of FeS2@PcD also changed from "OFF" state to "ON" state under the programmable regulation of H+ and H2O2. The program-regulated strategy based on FeS2@PcD realized specific fluorescence and MR dual-modality imaging-guided sono/chemodynamic therapies, representing a promising precision medicine approach.

Abstract :

Phthalocyanines are potentially promising photosensitizers (PSs) for photodynamic therapy (PDT), but the inherent defects such as aggregation-caused quenching effects and non-specific toxicity severely hinder their further application in PDT. Herein, we synthesized two zinc(II) phthalocyanines (PcSA and PcOA) monosubstituted with a sulphonate group in the alpha position with "O bridge" and "S bridge" as bonds and prepared a liposomal nanophotosensitizer (PcSA@Lip) by thin-film hydration method to regulate the aggregation of PcSA in the aqueous solution and enhance its tumor targeting ability. PcSA@Lip exhibited highly efficient production of superoxide radical (O-2(center dot-)) and singlet oxygen (O-1(2)) in water under light irradiation, which were 2.6-fold and 15.4-fold higher than those of free PcSA, respectively. Furthermore, PcSA@Lip was able to accumulate selectively in tumors after intravenous injection with the fluorescence intensity ratio of tumors to livers was 4.1:1. The significant tumor inhibition effects resulted in a 98% tumor inhibition rate after PcSA@Lip was injected intravenously at an ultra-low PcSA@Lip dose (0.8 nmol g(-1) PcSA) and light dose (30 J cm(-2)). Therefore, the liposomal PcSA@Lip is a prospective nanophotosensitizer possessing hybrid type I and type II photoreactions with efficient photodynamic anticancer effects.
