Sousa LRD, Duarte THC, Xavier VF, das Mercês AC, Vieira GM, Martins MD, Carneiro CM, dos Santos VMR, dos Santos ODH, Vieira PMDA. Benznidazole-Loaded Polymeric Nanoparticles for Oral Chemotherapeutic Treatment of Chagas Disease. Pharmaceutics 2024; 16:800. [PMID: 38931921 PMCID: PMC11207087 DOI: 10.3390/pharmaceutics16060800] [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: 04/30/2024] [Revised: 06/04/2024] [Accepted: 06/07/2024] [Indexed: 06/28/2024] Open
Abstract
Chagas disease (CD) is a worldwide public health problem. Benznidazole (BZ) is the drug used to treat it. However, in its commercial formulation, it has significant side effects and is less effective in the chronic phase of the infection. The development of particulate systems containing BZ is therefore being promoted. The objective of this investigation was to develop polymeric nanoparticles loaded with BZ and examine their trypanocidal impact in vitro. Two formulas (BNP1 and BNP2) were produced through double emulsification and freeze drying. Subsequent to physicochemical and morphological assessment, both formulations exhibited adequate yield, average particle diameter, and zeta potential for oral administration. Cell viability was assessed in H9C2 and RAW 264.7 cells in vitro, revealing no cytotoxicity in cardiomyocytes or detrimental effects in macrophages at specific concentrations. BNP1 and BNP2 enhanced the effect of BZ within 48 h using a treatment of 3.90 μg/mL. The formulations notably improved NO reduction, particularly BNP2. The findings imply that the compositions are suitable for preclinical research, underscoring their potential as substitutes for treating CD. This study aids the quest for new BZ formulations, which are essential in light of the disregard for the treatment of CD and the unfavorable effects associated with its commercial product.

Abstract
Pluronic polymers (pluronics) are a unique class of synthetic triblock copolymers containing hydrophobic polypropylene oxide (PPO) and hydrophilic polyethylene oxide (PEO) arranged in the PEO-PPO-PEO manner. Due to their excellent biocompatibility and amphiphilic properties, pluronics are an ideal and promising biological material, which is widely used in drug delivery, disease diagnosis, and treatment, among other applications. Through self-assembly or in combination with other materials, pluronics can form nano carriers with different morphologies, representing a kind of multifunctional pharmaceutical excipients. In recent years, the utilization of pluronic-based multi-functional drug carriers in tumor treatment has become widespread, and various responsive drug carriers are designed according to the characteristics of the tumor microenvironment, resulting in major progress in tumor therapy. This review introduces the specific role of pluronic-based polymer drug delivery systems in tumor therapy, focusing on their physical and chemical properties as well as the design aspects of pluronic polymers. Finally, using newer literature reports, this review provides insights into the future potential and challenges posed by different pluronic-based polymer drug delivery systems in tumor therapy.

Abstract
We report a chemo/starvation/chemodynamic trimodal combination therapy to combat multidrug-resistant (MDR) tumors by developing a ferrocene-containing nanovesicle (FcNV), which encapsulates glucose oxidase (GOx) in the hydrophilic core and coordinates cisplatin (Pt) in the hydrophobic layer (GOx&Pt@FcNV). Contrasting with other reported multimodal combination therapies, the new nanodrug (GOx&Pt@FcNV) relies on cascade reactions to drastically increase the overall effectiveness against MDR tumors. Specifically, Pt blocks deoxyribonucleic acid replication and activates hydrogen peroxide (H2O2) generation for chemotherapy; GOx consumes glucose to produce H2O2 and gluconic acid for starvation therapy; and all H2O2 products are catalyzed by ferrous ions decomposed from ferrocene to generate the highly toxic hydroxyl radicals (•OH) for chemodynamic therapy. The in vitro studies reveal that GOx&Pt@FcNV exhibits a highly efficient killing effect against various MDR tumor cells. The in vivo studies of double-tumor-bearing nude mice demonstrate that the tumor inhibitory rates (TIRs) of GOx&Pt@FcNV against cisplatin-resistant A549/DDP are 8.1 times and 3.3 times higher than those of Pt and Pt@FcNV, respectively; they are also 8.6 times and 4.3 times higher than Pt and Pt@FcNV against adriamycin-resistant MCF-7/ADR, respectively. This nanodrug with endogenous stimuli-activated cascade reactions offers a reference for the design of effective trimodal combination therapies to combat MDR tumors.

Abstract
It is well-known that vesicles serve as an excellent delivery platform for hydrophilic drugs. However, there is still a lack of a general and effective platform for hydrophobic drug loading. We herein disclose that water-soluble cross-linked reverse vesicles (cRVs) constructed from anionic surfactant 1, a counterpart of normal vesicles, would be excellent vehicles for hydrophobic drugs, the drug loading content (DLC) for which arrived up to 21.1%, 19.8%, and 25.8%, respectively, for three anticancer drugs, paclitaxel, camptothecin, and carmofur. This represents a general drug carrier with high drug loading content for various hydrophobic drugs without the assistance of other external forces. In addition to drug loading superiority, the cRVs were also characterized by robust stability, specific stimulus response, easy postfunctionalization, and good biocompatibility and thus are promising candidates for drug delivery systems.

Abstract
Very small polydopamine (PDA) polyethylene glycol (PEG) crosslinked copolymer (PDA-PEG) nanoparticles have been prepared following a convenient one-step procedure in aqueous solution. Particle sizes and colloidal stabilities have been optimized by varying PEG in view of chain length and end group functionalities. In particular, amine-terminated PEG3000 [PEG3000(NH2)2] reacted with polydopamine intermediates so that very small, crosslinked PDA-PEG nanoparticles with sizes of less than 50 nm were formed. These nanoparticles remained stable in buffer solution and no sedimentation occurred. Chemical functionalization was straight-forward as demonstrated by the attachment of fluorescent dyes. The PDA-PEG nanoparticles revealed efficient cellular uptake via endocytosis and high cytocompatibility, thus rendering them attractive candidates for cell imaging or for drug delivery applications.

Abstract
Here, a novel latent naphthalimide bearing water-soluble nanoprobes with catechol-Fe(III) cores (Fe@LNNPs) was designed, synthesized, and evaluated for in vivo fluorescence imaging of intracellular thiols, as various diseases are associated with overexpression of cellular biothiols. The Fe@LNNPs are mainly composed of three components. The inner part constitutes pyrocatechol groups, which can coordinate with Fe(III) to form a cross-linked core for improving the stability in the complex biological environment. The naphthalimide group is linked by disulfide with the core to quench the probe fluorescence. The outer part is designed to be a hydrophilic glycol corona for prolonging blood circulation. Also, a biotin group can be easily introduced into the nanoprobe for actively targeting the HepG2 cells. The fluorescence spectra reveals that the Fe@LNNPs can be reduced explicitly by glutathione to trigger the fluorescence emission. Confocal microscopic imagings and animal experiments manifest that the Fe@LNNPs, especially with biotin groups, have much better fluorescence signal imaging compared to the reported small-molecule probe 1' both in vitro and in vivo (up to 24 h). The Fe@LNNPs thus feature great advantages such as specificity, stability, biocompatibility, and long retention time for thiol-recognition imaging and hold potential applications in clinical cancer diagnosis.
