To generate rat models of anxiety and depression, this study respectively utilized m-chloropheniperazine (MCPP) and chronic unpredictable mild stress (CUMS). The effects of agarwood essential oil (AEO), agarwood fragrant powder (AFP), and agarwood line incense (ALI) on antidepressant and anxiolytic activity were explored through observations of rat behaviors using the open field test (OFT), light-dark exploration test (LDE), tail suspension test (TST), and forced swimming test (FST). Within the hippocampal area, the levels of 5-hydroxytryptamine (5-HT), glutamic acid (Glu), and γ-aminobutyric acid (GABA) were determined using the enzyme-linked immunosorbent assay (ELISA). To probe the anxiolytic and antidepressant mechanisms underlying agarwood inhalation, protein expression levels of glutamate receptor 1 (GluR1) and vesicular glutamate transporter type 1 (VGluT1) were measured employing the Western blot assay. Data revealed significant differences between the anxiety model group and the AEO, AFP, and ALI groups, with the latter demonstrating a reduction in total distance (P<0.005), movement velocity (P<0.005), increase in immobile time (P<0.005), and reduction in distance and velocity in the anxiety rat model within the dark box (P<0.005). The AEO, AFP, and ALI groups, compared to the depression model group, demonstrated an augmented total distance and average velocity (P<0.005), a decreased immobile time (P<0.005), and a diminished duration of forced swimming and tail suspension (P<0.005). Transmitter regulation varied significantly between the AEO, AFP, and ALI groups in the rat models of anxiety and depression. The anxiety model saw a reduction in Glu (P<0.005), alongside an increase in GABA A and 5-HT (P<0.005). However, in the depression model, the groups showed an increase in 5-HT levels (P<0.005), while decreasing GABA A and Glu levels (P<0.005). In tandem, the AEO, AFP, and ALI groups experienced an increase in protein expression for GluR1 and VGluT1 in the hippocampi of the rat models of anxiety and depression, respectively (P<0.005). In essence, AEO, AFP, and ALI show anxiolytic and antidepressant activity, potentially through influencing neurotransmitter control and modulating the expression of GluR1 and VGluT1 proteins within the hippocampal structure.
This research project seeks to observe how chlorogenic acid (CGA) influences microRNAs (miRNAs) in the context of protecting the liver from damage caused by N-acetyl-p-aminophenol (APAP). To form three distinct groups—a normal group, a model group (APAP, 300 mg/kg), and a CGA group (40 mg/kg)—eighteen C57BL/6 mice were randomly allocated. APAP, administered intragastrically at a dose of 300 mg per kg, induced hepatotoxicity in mice. At one hour post-APAP administration, the CGA group mice were gavaged with CGA (40 mg/kg). Six hours post-APAP administration, the mice were euthanized, and plasma and liver samples were procured for serum alanine/aspartate aminotransferase (ALT/AST) quantification and histopathological liver examination, respectively. selleck chemical Researchers used real-time PCR in combination with an miRNA array platform to pinpoint significant miRNAs. Employing miRWalk and TargetScan 72, miRNA target genes were predicted, validated by real-time PCR, and subsequently analyzed to determine functional annotations and enriched signaling pathways. Treatment with CGA successfully lowered the serum ALT/AST levels, previously elevated by APAP, effectively easing the associated liver injury. Nine microRNAs, with potential implications, were selected from the microarray data. Liver tissue was subjected to real-time PCR analysis to ascertain the presence and expression levels of miR-2137 and miR-451a. A significant upregulation of miR-2137 and miR-451a expression was observed following APAP administration, this upregulation being significantly reversed by subsequent CGA treatment, consistent with the array results. miR-2137 and miR-451a target genes were identified and then validated. CGA's safeguard against APAP-induced liver injury hinged upon the function of eleven target genes. Using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis with DAVID and R software, the 11 target genes were significantly enriched in Rho-protein-related signal transduction, vascular morphogenesis, transcription factor binding, and Rho guanine nucleotide exchange. Analysis of the results demonstrated that miR-2137 and miR-451a played a pivotal role in suppressing CGA's exacerbation of APAP-induced liver damage.
Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was employed for the qualitative analysis of monoterpene chemical constituents in Paeoniae Radix Rubra. Elution, performed using a gradient approach, was conducted on a C(18) high-definition column (21 mm x 100 mm, 25 µm) with a mobile phase consisting of 0.1% formic acid (A) and acetonitrile (B). With the column temperature set at 30 degrees Celsius, the flow rate was measured to be 0.04 milliliters per minute. Using an electrospray ionization (ESI) source, MS analysis was performed in both positive and negative ionization modes. selleck chemical The data processing procedure incorporated Qualitative Analysis 100. The identification of chemical components was a result of the synergistic use of fragmentation patterns, standard compounds, and mass spectra data reported in the literature. Scientists identified forty-one monoterpenoids as constituents of the Paeoniae Radix Rubra extract. In the analysis of Paeoniae Radix Rubra, eight compounds were identified for the first time, and another was proposed as the new compound 5-O-methyl-galloylpaeoniflorin, or its isomer. The research method presented here allows for the rapid determination of monoterpenoids in Paeoniae Radix Rubra, thus providing a solid basis for quality control and future investigation into the plant's pharmaceutical effects.
In Chinese medicine, Draconis Sanguis is a treasured material for its efficacy in activating blood and resolving stasis, with flavonoids as its primary active compounds. The complex flavonoid structures within Draconis Sanguis pose substantial difficulties in precisely characterizing its chemical composition. To gain insight into the molecular constituents of Draconis Sanguis, this study employed ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) to generate and analyze the mass spectral data. The methods of molecular weight imprinting (MWI) and mass defect filtering (MDF) were designed to rapidly screen flavonoids present in Draconis Sanguis. Mass spectrometry data acquisition, utilizing full-scan MS and tandem mass spectra (MS/MS), was performed in the positive ion mode for the m/z range of 100 to 1000. Previous literature indicated the use of MWI to locate reported flavonoids contained within Draconis Sanguis, and the mass tolerance for [M+H]+ was set at 1010~(-3). To improve the accuracy of flavonoid screening from Draconis Sanguis, an additional five-point MDF screening frame was created. Employing diagnostic fragment ions (DFI) and neutral loss (NL), along with mass fragmentation pathways, an analysis of the Draconis Sanguis extract preliminarily identified 70 compounds. These include 5 flavan oxidized congeners, 12 flavans, 1 dihydrochalcone, 49 flavonoid dimers, 1 flavonoid trimer, and 2 flavonoid derivatives. This research precisely determined the chemical structure of flavonoids extracted from Draconis Sanguis. Furthermore, it demonstrated that high-resolution mass spectrometry, coupled with data processing techniques like MWI and MDF, enabled a swift determination of the chemical makeup within Chinese medicinal substances.
