Biomed Pharmacother 2023; 167:115485. [PMID: 37713994 DOI: 10.1016/j.biopha.2023.115485] [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: 07/20/2023] [Revised: 09/02/2023] [Accepted: 09/08/2023] [Indexed: 09/17/2023] Open
Abstract
In this study, folate polyethylene glycol CTr albumin nanoparticles (FA-PEG-CTr-NPs) targeting hepatocellular carcinoma (HCC) were prepared. The nanoparticle preparation method was optimized using single-factor and response surface analysis. The prepared nanoparticles were characterized for their particle size, zeta potential, and morphology. The particle size and zeta potential were also determined. Additionally, drug loading, encapsulation efficiency, and in vitro drug release of the nanoparticles were determined. Using the Cell Counting Kit-8 method, their cytotoxicity and their cell-targeted uptake were determined using confocal microscopy and flow cytometry. Finally, the in vivo antitumor impact and tumor-targeting ability of the nanoparticles were evaluated by determining tumor volume inhibition and drug biodistribution and performing hematoxylin-eosin (H&E) staining. It was found that CTr could be effectively encapsulated into albumin nanoparticles and functionalized. The drug loading of the two nanoparticles was 67.12 ± 2.4% and 69.33 ± 2.8%, respectively. Regarding drug release, FA-PEG-CTr-NPs (89.0%) exhibited a superior release rate to CTr-NPs (70.5%) in an acidic environment. The in vitro experiments confirmed that FA-PEG-CTr-NPs yielded better cytotoxicity and faster drug uptake results than CTr and CTr-NPs. In vivo experiments confirmed that FA-PEG-CTr-NPs exhibited markedly better tumor inhibitory activity (inhibition rate was 80.21%), drug safety, and targeting than CTr and CTr-NPs. In conclusion, functionalized nanoparticles (FA-PEG-CTr-NPs) can specifically inhibit the malignant proliferation of HCC cells and are thus a promising nanoagent for the treatment of HCC.

Abstract
Streptonigrin is an aminoquinone alkaloid isolated from Streptomyces flocculus and is gaining attention as a drug molecule owing to its potential antitumor and antibiotic effects. It was previously used as an anticancer drug but has been discontinued because of its toxic effects. However, according to the most recent studies, the toxicity of streptonigrin and its structurally modified derivatives has been reduced while maintaining their potential pharmacological action at lower concentrations. To date, many investigations have been conducted on this molecule and its derivatives to determine the most effective molecule with low toxicity to enable new drug discovery. Therefore, the main objective of this study is to provide a comprehensive review and to discuss the prospects for streptonigrin and its derived compounds, which may boost the molecule as a highly interesting target molecule for new drug design, development and therapy. To complete this review, relevant literature was collected from several scientific databases, including Google Scholar, PubMed, Scopus and ScienceDirect. Following a complete screening, the obtained information is summarized in the present review to provide a good reference and accelerate the development and utilization of streptonigrin and its derivatives as pharmaceuticals.

Abstract
We explored the effect of phlorizin against cholinergic memory impairment and dysbacteriosis in D-galactose induced ICR mice. The control (CON) group, D-galactose model (DGM) group, and three groups (DG-PL, DG-PM, DG-PH) treated with phlorizin at 0.01%, 0.02%, and 0.04% (w/w) in diets were raised for 12 weeks. Supplementing with phlorizin reversed the loss of organ coefficient and body weight caused by D-galactose. The functional abilities of phlorizin on hippocampal-dependent spatial learning and memory, anti-oxidation, anti-inflammation were also observed. Meanwhile, phlorizin intervention upregulated the gene expression of Nrf2, GSH-PX, SOD1, decreased the gene expression of NF-κB, TLR-4, TNF-α, and IL-1β in the hippocampus, while enhanced the gene expression of JAM-A, Mucin2, Occludin in the caecum. Furthermore, a neurotransmitter of acetylcholine (ACh) was enhanced, while acetylcholinesterase (AChE) activity was inhibited by phlorizin administration. Moreover, phlorizin administration increased short-chain fatty acids (SCFAs) content, and reduced lipopolysaccharides (LPS) levels, which may relate to the rebuilding of gut microbiota homeostasis. Treatment with phlorizin may be an effective intervention for alleviating cognitive decline and gut microbiota dysbiosis.

An Overview of Traditional Uses, Phytochemical Compositions and Biological Activities of Edible Fruits of European and Asian Cornus Species. Foods 2022; 11:1240. [PMID: 35563963 PMCID: PMC9102190 DOI: 10.3390/foods11091240] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 04/16/2022] [Accepted: 04/19/2022] [Indexed: 02/05/2023] Open
Abstract
Cornus species are widely distributed in central and southern Europe, east Africa, southwest Asia, and America. Several species are known for edible fruits, especially Cornus mas and Cornus officinalis. These delicious fruits, characterized by their remarkable nutritional and biological values, are widely used in traditional medicine. In contrast to the other edible Cornus species, C. mas and C. officinalis are the most studied for which little information is available on the main phytochemicals and their biological activities. Fruits are characterised by several classes of secondary metabolites, such as flavonoids, phenolic acids, lignans, anthocyanins, tannins, triterpenoids, and iridoids. The available phytochemical data show that the different classes of metabolites have not been systematically studied. However, these edible species are all worthy of interest because similarities have been found. Thus, this review describes the traditional uses of Cornus species common in Europe and Asia, a detailed classification of the bioactive compounds that characterize the fruits, and their beneficial health effects. Cornus species are a rich source of phytochemicals with nutritional and functional properties that justify the growing interest in these berries, not only for applications in the food industry but also useful for their medicinal properties.

Abstract
D101 macroporous resin combined with high speed counter-current chromatography (D101 MR-HSCCC) was used to separate gallic acid (GA) from Cornus officinalis, and GA was added to starch-based products to improve food quality. The interaction and action mechanism of corn starch (CS) with GA were investigated for prediction and thereby controlling the structure and functions of starch-based foods. Results show that GA with 98.72% purity was successfully obtained using the D101 MR-HSCCC technique. HSCCC solvent system was composed of n-hexane-ethyl acetate-methanol-water (1:5:1:5, v/v/v/v). GA inhibited CS dissolution and improved CS swelling. Based on the particle size distribution, GA could enlarge the size of CS-GA complexes. FT-IR spectra exhibit that the interactions between CS and GA may comprise the intermolecular hydrogen bond and non-covalent bond. The results of XRD, LF-NMR and AFM show that the presence of GA could increase the relative crystallinity of CS, decrease the spin relaxation time (T2), and change the surface morphology of CS via the modification of hydrogen bonds distribution. Finally, SEM analysis indicates that GA could change the microstructure of CS-GA complexes. These findings facilitate the development of CS-based products and utilization of CS.

Abstract
Seven undescribed neoflavonoids, named melanoxylonins A-G, were isolated from the heartwood of Dalbergia melanoxylon, and all the non-toxic isolates were evaluated for their cardioprotective effect against ischemia/reoxygenation (I/R) injury in H9c2 cells. Of these, melanoxylonin A-D containing the 8-OH group showed better potent cardioprotective effects than the other four congeners. Molecular docking studies confirmed the capacity of melanoxylonin D to interact with the myeloperoxidase (MPO) protein. These results indicated that the potential cardioprotective effects of melanoxylonin D in H9c2 cells with I/R injury may be imparted through suppression of MPO. These results may provide a new medicinal usage of D. melanoxylon.

Abstract
Using various chromatographic methods, four new phenolics, coroffesters A-D (1 - 4) were isolated from the fruit of Cornus officinalis (Cornaceae). Their structures (1 - 4) were elucidated unambiguously by spectroscopic methods such as one- and two-dimensional nuclear magnetic resonance (1 D- and 2 D-NMR) spectroscopy and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS). The anti-inflammatory activity of the isolated compounds was also evaluated. All compounds (1 - 4) showed moderate inhibitory activity against NO production in a dose-dependent manner in RAW 264.7 cells.
