Abstract
Breast cancer, globally the most common cancer in women, presents significant challenges in treatment. Breast-conserving surgery (BCS), a less traumatic and painful alternative to radical mastectomy, not only preserves the breast's appearance but also supports postsurgical functional recovery. However, accurately identifying tumors, precisely delineating margins, and thoroughly removing metastases remain complex surgical challenges, exacerbated by the limitations of current imaging techniques, including poor tumor uptake and low signal contrast. Addressing these challenges, our study developed a series of GnRHR-targeted probes (YQGN-n) for fluorescence imaging and surgical navigation of breast cancer through a drug repositioning strategy. Notably, YQGN-7, with its high cellular affinity (Kd of 217.8 nM), demonstrates exceptional selectivity and specificity for breast cancer tumors, surpassing traditional imaging agents like ICG in tumor uptake and pharmacokinetic properties. Furthermore, YQGN-7's effectiveness in surgical navigation, both for primary breast tumors and metastases, highlights its potential as a revolutionary tool in BCS.

From disinfectants to antibiotics: Enhanced biosafety of quaternary ammonium compounds by chemical modification. JOURNAL OF HAZARDOUS MATERIALS 2023; 460:132454. [PMID: 37703742 DOI: 10.1016/j.jhazmat.2023.132454] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 08/30/2023] [Accepted: 08/30/2023] [Indexed: 09/15/2023]
Abstract
The excessive use of quaternary ammonium compounds (QACs) following the COVID-19 pandemic has raised substantial concerns regarding their biosafety. Overuse of QACs has been associated with chronic biological adverse effects, including genotoxicity or carcinogenicity. In particular, inadvertent intravascular administration or oral ingestion of QACs can lead to fatal acute toxicity. To enhance the biosafety and antimicrobial efficacy of QACs, this study reports a new series of QACs, termed as PACs, with the alkyl chain of benzalkonium substituted by a phthalocyanine moiety. Firstly, the rigid phthalocyanine moiety enhances the selectivity of QACs to bacteria over human cells and reduces alkyl chain's entropic penalty of binding to bacterial membranes. Furthermore, phthalocyanine neutralizes hemolysis and cytotoxicity of QACs by binding with albumin in plasma. Our experimental results demonstrate that PACs inherit the optical properties of phthalocyanine and validate the broad-spectrum antibacterial activity of PACs in vitro. Moreover, the intravascular administration of the most potent PAC, PAC1a, significantly reduced bacterial burden and ameliorated inflammation level in a bacteria-induced septic mouse model. This study presents a new strategy to improve the antimicrobial efficacy and biosafety of QACs, thus expanding their range of applications to the treatment of systemic infections.

Abstract
Supramolecular assemblies fabricated by peptide-photosensitizer conjugates have attracted increasing attentions in recent years as drug carriers for chemotherapeutics (CTs). However, these assemblies have been known to suffer from disintegration by serum components leading to off-target drug release, and thereby impairing antitumor effects and causing systemic toxicities. To address this problem, this study reports a nano-architectural self-assembly peptide-photosensitizer carrier (NSPC) fabricated by conjugating a phthalocyanine derivative (MCPZnPc) and ε-poly-l-lysine (EPL). By engineering the core and peripheral interactions, MCPZnPC-EPL (M-E) NSPC firmly encapsulated multiple CTs, creating CT@M-E NSPCs that were highly stable against disintegration in serum. More importantly, CT@M-E NSPCs exhibited controlled release of CTs in tumor tissues. The antitumor effects of CTs were further promoted by the synergism with the reactivated photodynamic effect. Furthermore, M-E NSPC-encapsulation optimized CTs' biodistribution reducing adverse effects in vivo. This study provides a serum-stable supramolecular drug delivery system with photodynamic effect, which is applicable for a broad-range of CTs to promote antitumor effects and ameliorate adverse effects.

Abstract
This review presents a robust strategy to design photosensitizers (PSs) for various species. Photodynamic therapy (PDT) is a photochemical-based treatment approach that involves the use of light combined with a light-activated chemical, referred to as a PS. Attractively, PDT is one of the alternatives to conventional cancer treatment due to its noninvasive nature, high cure rates, and low side effects. PSs play an important factor in photoinduced reactive oxygen species (ROS) generation. Although the concept of photosensitizer-based photodynamic therapy has been widely adopted for clinical trials and bioimaging, until now, to our surprise, there has been no relevant review article on rational designs of organic PSs for PDT. Furthermore, most of published review articles in PDT focused on nanomaterials and nanotechnology based on traditional PSs. Therefore, this review aimed at reporting recent strategies to develop innovative organic photosensitizers for enhanced photodynamic therapy, with each example described in detail instead of providing only a general overview, as is typically done in previous reviews of PDT, to provide intuitive, vivid, and specific insights to the readers.

Abstract
Combinational photo-based approaches with enhanced efficacy for cancer therapy have garnered increasing attention in recent years. In this work, a multifunctional system for synergistic photothermal and photodynamic cancer therapy was successfully prepared. The system consists of gold nanoflowers (AuNFs) conjugated with Chlorin e6 (Ce6), and then coated with a polydopamine (PDA) layer. AuNFs with diameters around 80 nm and a broad absorbance in the visible-near infrared (Vis-NIR) range of 500 to 800 nm, were successfully synthesized by a two-step process at 0 °C, using HAuCl4, ascorbic acid (AA), and hydroxylamine hydrochloride (NH2OH·HCl) as the reactants. Glutathione (GSH) molecules chemically anchored to the gold surfaces were used to provide addressable sites for Ce6 conjugated to GSH-AuNFs through an amidation reaction. A PDA layer was then wrapped outside the Ce6-GSH-AuNFs via self-polymerization of dopamine, which provided additional chemical modification and functionalization. Finally, the multifunctional PDA-Ce6-GSH-AuNFs were obtained. The content of Ce6 incorporated into the AuNFs was 14.0 wt%, and the singlet oxygen yield of PDA-Ce6-GSH-AuNFs was approximately 91.0% of that of free Ce6. PDA-Ce6-GSH-AuNFs showed better photothermal conversion efficiency (η = 23.6%), lower cytotoxicity, and faster cell internalization. Both in vitro and in vivo investigation of the combined treatment with a near-infrared (NIR) laser (660 nm for photodynamic therapy, and 808 nm for photothermal therapy) demonstrated that PDA-Ce6-GSH-AuNFs had excellent phototoxicity and synergistic effects of killing cancer cells. Hence, PDA-Ce6-GSH-AuNFs are a dual phototherapeutic agent that exhibits photodynamic and photothermal therapeutic effects and has potential application in enhanced cancer therapy.

Abstract
Photodynamic therapy (PDT) is a promising cancer treatment which involves a photosensitizer (PS), light at a specific wavelength for PS activation and oxygen, which combine to elicit cell death. While the illumination required to activate a PS imparts a certain amount of selectivity to PDT treatments, poor tumor accumulation and cell internalization are still inherent properties of most intravenously administered PSs. As a result, common consequences of PDT include skin photosensitivity. To overcome the mentioned issues, PSs may be tailored to specifically target overexpressed biomarkers of tumors. This active targeting can be achieved by direct conjugation of the PS to a ligand with enhanced affinity for a target overexpressed on cancer cells and/or other cells of the tumor microenvironment. Alternatively, PSs may be incorporated into ligand-targeted nanocarriers, which may also encompass multi-functionalities, including diagnosis and therapy. In this review, we highlight the major advances in active targeting of PSs, either by means of ligand-derived bioconjugates or by exploiting ligand-targeting nanocarriers.

Abstract
Porphyrin-based molecules are actively studied as dual function theranostics: fluorescence-based imaging for diagnostics and fluorescence-guided therapeutic treatment of cancers. The intrinsic fluorescent and photodynamic properties of the bimodal molecules allows for these theranostic approaches. Several porphyrinoids bearing both hydrophilic and/or hydrophobic units at their periphery have been developed for the aforementioned applications, but better tumor selectivity and high efficacy to destroy tumor cells is always a key setback for their use. Another issue related to their effective clinical use is that, most of these chromophores form aggregates under physiological conditions. Nanomaterials that are known to possess incredible properties that cannot be achieved from their bulk systems can serve as carriers for these chromophores. Porphyrinoids, when conjugated with nanomaterials, can be enabled to perform as multifunctional nanomedicine devices. The integrated properties of these porphyrinoid-nanomaterial conjugated systems make them useful for selective drug delivery, theranostic capabilities, and multimodal bioimaging. This review highlights the use of porphyrins, chlorins, bacteriochlorins, phthalocyanines and naphthalocyanines as well as their multifunctional nanodevices in various biomedical theranostic platforms.

Abstract
Antimicrobial photodynamic therapy (aPDT) is an effective way to combat infectious diseases and antibiotic resistance. Photosensitizer is a key factor of aPDT and has triggered extensive research interest. In this study, a new asymmetric Zn(II) phthalocyanine mono-substituted with a triazatricyclodecane moiety (compound 3) and its cationic N-methylated derivative (compound 4) were synthesized. Their photodynamic antimicrobial activities were evaluated using bioluminescent bacterial strains. Compound 3 showed phototoxicity only toward the Gram-positive bacteria, whereas the cationic derivative compound 4 exhibited strong anti-bacterial activity against both Gram-positive and Gram-negative strains. These bacterial species were eradicated (>4.0 logs or 99.99% killing) at appropriate concentrations of compound 4 with 12.7 J/cm2 of red light, demonstrating compound 4 as a potent aPDT agent.

Abstract
There is a growing interest for the discovery of new cancer-targeted delivery systems for drug delivery and diagnosis. A synopsis of the bibliographic data will be presented on bombesin, neurotensin, octreotide, Arg-Gly-Asp, luteinizing hormone-releasing hormone and other peptides. Many of them have reached the clinics for therapeutic or diagnostic purposes, and have been utilized as carriers of known cytotoxic agents such as doxorubicin, paclitaxel, cisplatin, methotrexate or dyes and radioisotopes. In our article, recent advances in the development of peptides as carriers of cytotoxic drugs or radiometals will be analyzed.

Abstract
Clinical photosensitizers suffer from the disadvantages of fast photobleaching and high systemic toxicities because of the off-target photodynamic effects. To address these problems, we report a self-assembled pentalysine-phthalocyanine assembly nanodots (PPAN) fabricated by an amphipathic photosensitizer-peptide conjugate. We triggered the photodynamic therapy effects of photosensitizers by precisely controlling the assembly and disintegration of the nanodots. In physiological aqueous conditions, PPAN exhibited a size-tunable spherical conformation with a highly positive shell of the polypeptides and a hydrophobic core of the π-stacking Pc moieties. The assembly conformation suppressed the fluorescence and the reactive oxygen species generation of the monomeric photosensitizer molecules (mono-Pc) and thus declined the photobleaching and off-target photodynamic effects. However, tumor cells disintegrated PPAN and released the mono-Pc molecules, which exhibited fluorescence for detection and the photodynamic effects for the elimination of the tumor tissues. The molecular dynamics simulations revealed the various assembly configurations of PPAN and illustrated the assembly mechanism. At the cellular level, PPAN exhibited a remarkable phototoxicity to breast cancer cells with the IC50 values in a low nanomolar range. By using the subcutaneous and orthotopic breast cancer animal models, we also demonstrated the excellent antitumor efficacies of PPAN in vivo.
