RSC Adv 2024; 14:7338-7349. [PMID: 38433936 PMCID: PMC10906141 DOI: 10.1039/d3ra08434e] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Accepted: 02/20/2024] [Indexed: 03/05/2024] Open
Abstract
Fisetin (FST), a natural flavonoid compound derived from various fruits and vegetables, including apple, strawberry, and onion, demonstrates potential for a wide range of pharmaceutical applications, including potential anticancer properties. However, challenges such as low bioavailability, poor aqueous solubility, and limited permeability restrict the use of FST in the pharmaceutical sector. Nowadays, targeted nanomedicines have garnered attention to overcome limitations associated with phytochemicals, including FST. In the present study, we have designed and successfully prepared folate-targeted FST nanoparticles (FFNPs). Characterization through DLS and FE-SEM revealed the successful preparation of monodisperse (PDI: 0.117), nanoscale-sized (150 nm), and spherical nanoparticles. Physicochemical characterization including FTIR, XRD, DSC, and TGA analysis, confirmed the encapsulation of the FST within the Folic acid (FA) - conjugated nanoparticles (CNPs) and revealed its amorphous nature. Molecular docking analysis revealed the strong binding affinity and specific amino acid interactions involved in the BSA-FST-FA complex, suggesting the potential synergistic effect of FST and FA in enhancing the therapeutic activity of the FFANPs. Cytotoxic assessments by the MTT assay, migration assay, AO-EtBr staining assay, colony formation assay, and cellular uptake study demonstrated enhanced anticancer efficacy, apoptosis induction, and enhanced uptake of FFNPs compared to pure FST. These findings propose prepared FFNPs as a promising targeted drug delivery nanocarrier for effective FST delivery in cancer therapy.

The therapeutic efficacy of silver loaded rhenium disulfide nanoparticles as a photothermal agent for cancer eradication. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY. B, BIOLOGY 2024; 250:112831.

Abstract
Cancer is a life-threatening disease when it is diagnosed at a late stage or treatment procedures fail. Inhibiting cancer cells in the tumor environment is a significant challenge for anticancer therapy. The photothermal effects of nanomaterials are being studied as a new cancer treatment. In this work, rhenium disulfide (ReS2) nanosheets were made by liquid exfoliation with gum arabic (GA) and coated with silver nanoparticles (AgNPs) to produce reactive oxygen species that destroy cancer cells. The synthesized AgNP-GA-ReS2 NPs were characterized using UV, DLS, SEM, TEM, and photothermal studies. According to the DLS findings, the NPs were about 216 nm in size and had a zeta potential of 76 mV. The TEM and SEM analyses revealed that the GA-ReS2 formed single-layered nanosheets on which the AgNPs were distributed. The photothermal effects of the AgNP-GA-ReS2 NPs at 50 μg/mL were tested with an 808 nm laser at 1.2 W cm-2, and they reached 55.8 °C after 5 min of laser irradiation. MBA-MB-231 cells were used to test the cytotoxicity of the newly designed AgNP-GA-ReS2 NPs with and without laser irradiation for 5 min. At 50 μg/mL, the AgNP-GA-ReS2 showed cytotoxicity, which was confirmed with calcein and EtBr staining. The DCFH-DA and flow cytometry analyses demonstrated that AgNP-GA-ReS2 nanosheets under NIR irradiation generated ROS with high anticancer activity, in addition to the photothermal effects.

Abstract
AIM Folate receptor expression increase up to 30% in breast cancer cells and could be used as a possible ligand to couple to folate-functionalized nanoparticles. Metformin (Met) is an anti-hyperglycemic agent whose anti-cancer properties have been formerly reported. Consequently, in the current study, we aimed to synthesize and characterize folate-functionalized PLGA-PEG NPs loaded with Met and evaluate the anti-cancer effect against the MDA-MB-231 human breast cancer cell line. METHODS FA-PLGA-PEG NPs were synthesized by employing the W1/O/W2 technique and their physicochemical features were evaluated by FE-SEM, TEM, FTIR, and DLS methods. The cytotoxic effects of free and Nano-encapsulated drugs were analyzed by the MTT technique. Furthermore, RT-PCR technique was employed to assess the expression levels of apoptotic and anti-apoptotic genes. RESULT MTT result indicated Met-loaded FA-PLGA-PEG NPs exhibited cytotoxic effects in a dose-dependently manner and had more cytotoxic effects relative to other groups. The remarkable down-regulation (hTERT and Bcl-2) and up-regulation (Caspase7, Caspase3, Bax, and p53) gene expression were shown in treated MDA-MB-231 cells with Met-loaded FA-PLGA-PEG NPs. CONCLUSION Folate-Functionalized PLGA-PEG Nanoparticles are suggested as an appropriate approach to elevate the anticancer properties of Met for improving the treatment effectiveness of breast cancer cells.

Abstract
The advances in producing multifunctional lipid-polymer hybrid nanoparticles (LPHNs) by combining the biomimetic behavior of liposomes and architectural advantages of polymers have provided great opportunities for selective and efficient therapeutics delivery. The constructed LPHNs exhibit different therapeutic efficacies for special uses based on characteristics of different excipients. However, the high mechanical/structural stability of hybrid nano-systems could be viewed as both a negative property and a positive feature, where the concomitant release of drug molecules in a controllable manner is required. In addition, difficulties in scaling up the LPHNs production, due to involvement of several criteria, limit their application for biomedical fields, especially in monitoring, bioimaging, and drug delivery. To address these challenges bio-modifications have exhibited enormous potential to prepare reproducible LPHNs for site-specific therapeutics delivery, diagnostic and preventative applications. The ever-growing surface bio-functionality has provided continuous vitality to this biotechnology and has also posed desirable biosafety to nanoparticles (NPs). As a proof-of-concept, this manuscript provides a crucial review of coated lipid and polymer NPs displaying excellent surface functionality and architectural advantages. We also provide a description of structural classifications and production methodologies, as well as the biomedical possibilities and translational obstacles in the development of surface modified nanocarrier technology.

Abstract
Breast cancer is the primary reason for cancer-related death in women worldwide and the development of new formulations to treat breast cancer patients is crucial. Curcumin (Cur), a natural product, exerts promising anticancer activities against various cancer types. However, its therapeutic efficacy is hindered as a result of poor water solubility, instability, and low bioavailability. The aim of this work is to assess the curative effect of a novel nanoformulation, i.e., Cur-loaded and calcium-doped dendritic mesoporous silica nanoparticles modified with folic acid (Cur-Ca@DMSNs-FA) for breast cancer therapy. The results manifested that Cur-Ca@DMSNs-FA dispersed very well in aqueous solution, released Cur with a pH-responsible profile, and targeted efficiently to human breast cancer MCF-7 cells. Further investigations indicated that Cur-Ca@DMSNs-FA effectively inhibited cell proliferation, increased intracellular ROS generation, decreased mitochondrial membrane potential, and enhanced cell cycle retardation at G2/M phase, leading to a higher apoptosis rate in MCF-7 compared to free Cur. Moreover, the Western blotting analysis demonstrated that Cur-Ca@DMSNs-FA were more active than free Cur through suppression of PI3K/AKT/mTOR and Wnt/β-catenin signaling, and activation of the mitochondria-mediated apoptosis pathway. In addition, hemolysis assay showed that the Ca@DMSNs-FA exhibited good biocompatibility. Last, in vivo studies indicated that when Cur was encapsulated in Ca@DMSNs-FA, the Cur concentration in blood serum and tumor tissues was increased after 1 h intraperitoneal injection. In conclusion, Cur-Ca@DMSNs-FA might act as a potential anticancer drug formulation for breast cancer therapy.

Abstract
Reactive oxygen species (ROS) induced oxidative stress is one of the major factors responsible for initiation of several intracellular toxic events that leads to cell death. Antioxidant enzymes defence system of the body is responsible for maintaining the oxidative balance and cellular homeostasis. Several diseases are promoted by the excessive oxidative stress caused by the impaired antioxidant defence system that leads to oxidant/antioxidant imbalance in the body. In order to restore or precise the aberrant antioxidant system, a large number of catalytic nanoparticles has been screened so far. Exceptional antioxidative activity of nanoceria made it as a potential antioxidative nano-agent for the effective scavenging of toxic ROS. In this work albumin coated nanoceria (ANC) was synthesized and further characterised by various physicochemical techniques. The antioxidant and superoxide dismutase (SOD) assay confirm that the albumin coating do not alter the antioxidant potential of ANC. The biocompatibility and protective efficacy of ANC against oxidative stress was investigated both in vitro and in vivo in human lung epithelial (L-132) cells and zebrafish embryos, respectively. The inductively coupled plasma mass spectrometry (ICP-MS), transmission electron microscopy (TEM) and field emission scanning electron microscope (FE-SEM) analysis corroborates the uptake of ANC by the cells. Furthermore, the semi-quantitative gene expression studies confirmed that the ANC successfully defend the cells against oxidative stress by preserving the antioxidant system of the cells. Thus, the current work open up a new avenue for the development of improved antioxidant nano-drug therapies.
