Consequently, this study focuses on harnessing the value of olive roots, identifying bioactive phytochemicals and evaluating their biological effects, including cytotoxicity and antiviral properties in extracts from the Olea europaea Chemlali cultivar. Analysis by liquid chromatography-mass spectrometry (LC-MS) was conducted on the extract produced by ultrasonic extraction. The microculture tetrazolium assay (MTT) was employed to assess cytotoxicity against VERO cells. Later, the antiviral action was examined regarding HHV-1 (human herpesvirus type 1) and CVB3 (coxsackievirus B3) viral propagation within the infected VERO cellular environment. The LC-MS procedure identified 40 compounds, including secoiridoids (53%), organic acids (13%), iridoids (10%), lignans (8%), caffeoylphenylethanoids (5%), phenylethanoids (5%), sugars and derivatives (2%), phenolic acids (2%), and flavonoids (2%). Exposure to the extracts did not induce harmful effects on VERO cells. In addition, the extracted portions had no impact on the appearance of HHV-1 or CVB3 cytopathic effects in the infected VERO cells, and did not lessen the viral infectious count.
The plant, Lonicera japonica Thunb., is found across various regions and is valuable for its ornamental, economic, edible, and medicinal properties. The phytoantibiotic L. japonica's potent therapeutic action extends to various infectious diseases, marked by its broad-spectrum antibacterial properties. The anti-diabetic, anti-Alzheimer's disease, anti-depression, antioxidative, immunoregulatory, anti-tumor, anti-inflammatory, anti-allergic, anti-gout, and anti-alcohol-addiction activities exhibited by L. japonica could be a consequence of the presence of bioactive polysaccharides isolated from it. Researchers, employing water extraction, alcohol precipitation, enzyme-assisted extraction, and chromatographic techniques, have precisely determined the molecular weight, chemical structure, and monosaccharide composition and ratio of L. japonica polysaccharides. Using Lonicera as a keyword, a 12-year literature review was conducted across the Chinese Pharmacopoeia, Flora of China, Web of Science, PubMed, and CNKI databases. Polysaccharides, characteristic of Lonicera, specifically the japonica variety, merit attention. Japonica, as classified by Thunberg. A comprehensive systematic review of *Lonicera japonica* polysaccharides, specifically honeysuckle polysaccharides, examined extraction and purification, structural features, their effects on health, and the structure-activity relationship, to guide future research. We investigated the multifaceted applications of L. japonica polysaccharides in the food, medicine, and household product industries, illustrating potential uses as a raw material for lozenges, soy sauce, and toothpaste production. A helpful guide for enhancing the functionality of products derived from L. japonica polysaccharides will be provided in this review.
This study details the in vitro and in vivo pharmacological actions of LP1 analogs, completing a series of structural alterations designed to enhance analgesic potency. virus genetic variation The N-substituent's phenyl ring in the lead compound LP1 was changed by replacing it with either an electron-rich or an electron-poor ring and subsequently connected to the basic nitrogen of the (-)-cis-N-normetazocine structure using a propanamide or butyramide linker. In assays measuring radioligand binding, compounds 3 and 7 exhibited nanomolar binding affinity to the opioid receptor (MOR), resulting in Ki values of 596,008 nM and 149,024 nM, respectively. Compound 3, in the mouse vas deferens assay, displayed an antagonistic action against the highly selective MOR prototype agonist DAMGO. In contrast, compound 7 produced a naloxone-reversible response at the MOR. Compound 7, equally efficacious as LP1 and DAMGO at the MOR receptor, demonstrated a reduction in thermal and inflammatory pain as measured by the mouse tail-flick test and the rat paw pressure thresholds (PPTs) in the Randall-Selitto test.
Within a physiological buffer, the process of dissolving phthalic selenoanhydride (R-Se) liberates diverse reactive selenium species, including hydrogen selenide (H2Se). While a potential selenium supplement compound displays multiple biological actions, the effect on the cardiovascular system remains undetermined. Consequently, this investigation sought to explore the impact of R-Se on hemodynamic parameters and vasoactive properties in rat arteries, in vitro. In anesthetized male Wistar rats, the right jugular vein was cannulated for intravenous administration of R-Se. Cannulation of the left carotid artery allowed for the detection of the arterial pulse waveform (APW), facilitating the evaluation of 35 parameters. R-Se (1-2 mol kg-1) presented a temporary impact on most APW parameters, including a decrease in systolic and diastolic blood pressure, heart rate, dP/dtmax relative level, or anacrotic/dicrotic notch values, contrasting with the unchanged response to phthalic anhydride or phthalic thioanhydride, while systolic area, dP/dtmin delay, dP/dtd delay, anacrotic notch relative level, or its delay experienced an upward trend. R-Se (approximately 10-100 mol/L) led to a significant drop in tension of pre-contracted mesenteric, femoral, and renal arteries, whereas a moderately vasodilatory effect was found in isolated thoracic aortas from normotensive Wistar rats. The results point to R-Se's action on vascular smooth muscle cells, which may be the causative factor behind its effects on the hemodynamic characteristics of rats.
Borate-based scorpionate ligands, particularly those incorporating the 7-azaindole heterocycle, remain largely unexamined in the realm of coordination chemistry. Following this, a more detailed investigation into their coordination chemistry is warranted. The focus of this article is the synthesis and characterization of a set of complexes constructed with anionic, adaptable scorpionate ligands, of the form [(R)(bis-7-azaindolyl)borohydride]- ([RBai]-), where R is either methyl, phenyl, or naphthyl. Copper(I) complexes, incorporating a phosphine co-ligand and three distinct ligands, were synthesized. These complexes include [Cu(MeBai)(PPh3)] (1), [Cu(PhBai)(PPh3)] (2), [Cu(NaphthBai)(PPh3)] (3), [Cu(MeBai)(PCy3)] (4), [Cu(PhBai)(PCy3)] (5), and [Cu(NaphthBai)(PCy3)] (6). The crystallization efforts of complexes 4 and 2, respectively, led to the unintended production of further copper(II) complexes, including [Cu(MeBai)2] (7) and [Cu(PhBai)2] (8). Employing CuCl2 and two equivalents of the relevant Li[RBai] salt, complexes 7 and 8 were prepared independently, alongside the creation of a further complex, [Cu(NaphthBai)2] (9). Characterizing the copper(I) and copper(II) complexes involved the use of spectroscopic and analytical methods. In parallel, the crystal structure was elucidated for eight of the nine complexes. A 3-N,N,H coordination mode was observed consistently in the interaction between the boron-based ligand and the metal centers.
The intricate process of degrading and modifying organic matter, including wood, is undertaken by diverse organisms, including fungi, bacteria, and actinomycetes, culminating in the formation of valuable nutrients. A sustainable economy's objective revolves around the efficient use of waste as raw materials, leading to the increased application of biological treatments to facilitate the breakdown of lignocellulosic waste. pathological biomarkers One potential means of biodegrading the significant quantities of lignocellulosic material resulting from wood waste in forestry and the wood industry is the composting method. In particular, a microbiological inoculum, rich in dedicated fungal species, can contribute to the biodegradation of wood waste and the biotransformation of substances from wood protection, such as pentachlorophenol (PCP), lindane (hexachlorobenzene), and polycyclic aromatic hydrocarbons (PAHs). A literature review was undertaken to evaluate the utility of decay fungi in the context of toxic biotransformation processes. The reviewed literature suggests that fungal species, including Bjerkandera adusta, Phanerochaete chrysosporium, and Trametes versicolor, could be instrumental in developing effective biological consortia for composting wood waste contaminated with pentachlorophenol, lindane, and polycyclic aromatic hydrocarbons (PAHs).
