Exploring the mechanism of anti-hereditary Parkinson's disease of baicalein based on PINK1 RNAi Drosophila model / 药学学报

The aim of this study was to investigate the effect of baicalein on a Drosophila model of hereditary Parkinson's disease caused by gene mutations and to preliminarily elucidate the mechanism of baicalein in delaying hereditary Parkinson's disease. In this paper, PTEN-induced putative kinase 1 (PINK1)-RNAi Parkinson's Drosophila were used as the model group and wild-type Drosophila w1118 were used as the control group. Different doses of baicalein and Madopa were administered to the model group to observe their effects on the life span, motor ability, the abnormal rate of wings, dopamine content and dopaminergic neurons of PINK1-RNAi Parkinson's Drosophila and their effects on mitochondrial dysfunction including adenosine triphosphate (ATP), mitochondrial DNA (mtDNA) and reactive oxygen species (ROS) content. The results showed that the effective administration doses of baicalein were 0.8 mg·mL-1 for low concentration, 1.6 mg·mL-1 for medium concentration and 3.2 mg·mL-1 for high concentration, and the optimal administration dose of the positive drug Madopa was 0.1 μg·mL-1. Baicalein and Madopa could significantly improve the life span, exercise ability and reduce the abnormal rate of wings of PINK1-RNAi male Drosophila (P < 0.05), and low dose baicalein showed the best effect; baicalein could improve the loss of dopaminergic neurons, and the effects of low dose and high dose were the best, but Madopa showed no significant effect; baicalein and Madopa had no significant effect on dopamine content (P > 0.05). Baicalein and Madopa could increase the ATP content of PINK1-RNAi male Drosophila (P < 0.05), and low dose baicalein showed the best effect; middle dose baicalein could significantly increase the mtDNA content of PINK1-RNAi male Drosophila (P < 0.05), but Madopa had no significant effect; baicalein and Madopa had no significant effect on ROS content (P > 0.05).

The preventive effect and mechanism of Dayuanyin in hypoxic pulmonary hypertension through NF-κB signaling pathway / 药学学报

Dayuanyin (DYY) has been shown to reduce lung inflammation in both coronavirus disease 2019 (COVID-19) and lung injury. This experiment was designed to investigate the efficacy and mechanism of action of DYY against hypoxic pulmonary hypertension (HPH) and to evaluate the effect of DYY on the protection of lung function. Animal welfare and experimental procedures are approved and in accordance with the provision of the Animal Ethics Committee of the Institute of Materia Medica, Chinese Academy of Medical Science. Male C57/BL6J mice were randomly divided into 4 groups: control group, model group, DYY group (800 mg·kg-1), and positive control sildenafil group (100 mg·kg-1). The animals were given control solvents or drugs by gavage three days in advance. On day 4, the animals in the model group, DYY group and sildenafil group were kept in a hypoxic chamber containing 10% ± 0.5% oxygen, and the animals in the control group were kept in a normal environment, and the control solvent or drugs continued to be given continuously for 14 days. The right ventricular systolic pressure, right ventricular hypertrophy index, organ indices and other metrics were measured in the experimental endpoints. Meantime, the expression levels of the inflammatory factors in mice lung tissues were measured. The potential therapeutic targets of DYY on pulmonary hypertension were predicted using network pharmacology, the expression of nuclear factor kappa B (NF-κB) signaling pathway-related proteins were measured by Western blot assay. It was found that DYY significantly reduced the right ventricular systolic pressure, attenuated lung injury and decreased the expression of inflammatory factors in mice. It can also inhibit hypoxia-induced activation of NF-κB signaling pathway. DYY has a protective effect on lung function, as demonstrated by DYY has good efficacy in HPH, and preventive administration can slow down the disease progression, and its mechanism may be related to inhibit the activation of NF-κB and signal transducer and activator of transcription 3 (STAT3) by DYY.

Research progress in drugs targeting tumor associated macrophage / 药学学报

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

Based on plasma metabonomics and network analysis to research the mechanisms of Chaigui granules for treating depression / 药学学报

The purpose of this study was to systematically analyze the antidepressant mechanism of Chaigui granules from the perspective of biological metabolic network by using integrated metabolomics and biological network analysis tools. The model of chronic unpredictable mild stress (CUMS) depression rat was established, and LC-MS-based plasma metabolomics was used to identify the key metabolites and analyze metabolic pathways underlying the antidepressant effects of Chaigui Granules. The key metabolites regulated by Chaigui granules was integrated with biological network analysis tools to further focus on the key metabolic pathways and explore the potential targets of the antidepressant effect of Chaigui granules. The results showed that there were significant differences in the plasma levels of 20 metabolites in the model group compared with the control group (P < 0.05), Chaigui granules significantly regulated 12 metabolites including docosatrienoic acid, 3-hydroxybutyric acid, 4-hydroxybenzaldehyde, chenodeoxycholic acid, cholic acid, L-glutamine, glycocholic acid, linoleyl carnitine, L-tyrosine, N-acetylvaline, palmitoylcarnitine, arachidonic acid. Further network analysis of the key metabolites regulated by Chaigui granules indicated that plasma arachidonic acid metabolism might be the core pathway for the antidepressant effect of Chaigui granules, with 10 proteins were potential targets for the antidepressant effect of Chaigui granules, including CYP2B6, CYP2E1, CYP2C9, CYP2C8, PLA2G6, PTGS2, ALOX15B, PTGS1, ALOX12 and ALOX5.

Puerarin reduces oxidative damage to vascular endothelial cells by improving mitochondrial respiratory function / 药学学报

This study investigated the effect of puerarin on human umbilical vein endothelial cells (HUVEC) injured with hydrogen peroxide (H2O2). HUVEC were divided into three groups: a control group, a model group (H2O2 400 μmol·L-1) and a puerarin-treated group (3, 10, 30 and 100 μmol·L-1). HUVEC were cultured with varied concentration of puerarin for 2 h and treated with H2O2 for another 24 h. Cell proliferation was detected by a CCK-8 assay. The mitochondrial membrane potential was measured by a JC-1 fluorescent probe. A transwell chamber assay was adopted to observe cell migration ability. Mitochondrial respiratory function was measured in a two-chamber titration injection respirometer (Oxygraph-2k). The expression of interleukin-1β (IL-1β), interleukin-18 (IL-18) and tumor necrosis factor-α (TNF-α) was detected by quantitative real-time PCR. The expression of pyroptosis-mediated proteins, including cleaved-cysteinyl aspartate-specific proteinase-1 (caspase-1), N-gasdermin D (N-GSDMD), NOD-like receptor protein 3 (NLRP3) and purinergic ligand-gated ion channel 7 receptor (P2X7R) was detected by Western blot. The results show that 400 μmol·L-1 H2O2 treatment for 24 h causes obvious damage to HUVEC. Compared with the model group, puerarin protected against cellular injury in a dose-dependent manner, with the greatest effect at a dose of 30 and 100 μmol·L-1. Puerarin significantly decreased the mitochondrial membrane potential and improved mitochondrial function. Puerarin inhibited cell migration induced by H2O2, suppressed the expression of IL-1β, IL-18 and TNF-α, and down-regulated the pyroptosis-mediated protein. These changes are statistically significant (P < 0.05). These findings demonstrate that puerarin has a protective effect against H2O2-induced oxidative damage of HUVEC by inhibiting the migration of HUVEC cells. The mechanism may be related to improved mitochondrial respiratory function and inhibition of pyroptosis.

The mechanisms of type 2 diabetic skeletal muscle atrophy and the effects of commonly used hypoglycemic drugs: a review / 药学学报

Type 2 diabetes is a hypermetabolic disease characterized with disorders of glucose/lipid metabolism, absolute or relative lack of insulin, and can induce skeletal muscle atrophy. Hyperglycemia, hyperlipidemia, insulin resistance, and abnormal release of inflammatory factors can lead to abnormal signal transduction in skeletal muscle, thus make protein synthesis and degradation imbalance and eventually causing muscle atrophy. Under normal conditions, insulin-like growth factor 1 (IGF-1)/insulin can activate phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT). AKT not only increases protein synthesis through mammalian target protein of rapamycin (mTOR), but also phosphorylates forkhead box O (FoxO) transcription factor and then inhibits the transcription of several ubiquitin ligases (such as MAFbx/atrogin-1 and MuRF1), or autophagy related genes. The weakened IGF-1/PI3K/AKT pathway in type 2 diabetes is an important factor leading to skeletal muscle atrophy. Studies have shown that the commonly used anti-type 2 diabetic drugs have different effects in regulating the synthesis and degradation of skeletal muscle protein. Studies reported that drugs with effect of anti-diabetic muscle atrophy include thiazolidinediones, glucagon-like peptide analogs, glucose-sodium cotransporter 2 inhibitors, etc.; drugs that are still in controversial or even promote skeletal muscle atrophy include metformin, and some sulfonylurea or non-sulfonylurea insulin secretagogues. This article overviewed and analyzed the currently commonly used drugs for type 2 diabetes and summarized the related mechanisms, with the aim to provide references for the rational applications of drugs for type 2 diabetes.

Identification of multi-target anti-cancer agents from TCM formula by in silico prediction and in vitro validation / 中国天然药物

Cancer is a complex disease associated with multiple gene mutations and malignant phenotypes, and multi-target drugs provide a promising therapy idea for the treatment of cancer. Natural products with abundant chemical structure types and rich pharmacological characteristics could be ideal sources for screening multi-target antineoplastic drugs. In this paper, 50 tumor-related targets were collected by searching the Therapeutic Target Database and Thomson Reuters Integrity database, and a multi-target anti-cancer prediction system based on mt-QSAR models was constructed by using naïve Bayesian and recursive partitioning algorithm for the first time. Through the multi-target anti-cancer prediction system, some dominant fragments that act on multiple tumor-related targets were analyzed, which could be helpful in designing multi-target anti-cancer drugs. Anti-cancer traditional Chinese medicine (TCM) and its natural products were collected to form a TCM formula-based natural products library, and the potential targets of the natural products in the library were predicted by multi-target anti-cancer prediction system. As a result, alkaloids, flavonoids and terpenoids were predicted to act on multiple tumor-related targets. The predicted targets of some representative compounds were verified according to literature review and most of the selected natural compounds were found to exert certain anti-cancer activity in vitro biological experiments. In conclusion, the multi-target anti-cancer prediction system is very effective and reliable, and it could be further used for elucidating the functional mechanism of anti-cancer TCM formula and screening for multi-target anti-cancer drugs. The anti-cancer natural compounds found in this paper will lay important information for further study.

Use of network pharmacology to analyze compound reserpine and triamterene tablets in the treatment of hypertension / 药学学报

Compound reserpine and triamterene tablets (CRTT), a compound antihypertensive drug developed by Chinese scientists, is still widely used in clinical practice. However, the mechanisms by which CRTT treats hypertension remain to be fully understood. This study used network pharmacology to analyze CRTT's antihypertensive mechanisms with in vitro experiments. The targets of the four chemical components of CRTT were collected from the Swiss Target Prediction database; 1 828 protein targets related to hypertension were collected from the Therapeutic Target Database (TTD) and Online Mendelian Inheritance in Man (OMIM) database. The CRTT-hypertension network model was constructed using a search tool for recurring instances of neighbouring genes (STRING). Gene ontology (GO) and pathway enrichment analysis of targets of interest was conducted with the Metascape database. In the in vitro study, human umbilical vein endothelial cells (HUVEC) and vascular smooth muscle cells (VSMC) were treated with 1 μmol·L-1 angiotensin Ⅱ (AngⅡ) and CRTT was administered at concentrations of 0.01, 0.1, and 1 μmol·L-1. Changes in the phosphatidylinositol-3-kinase/protein serine threonine kinase/endothelial nitric oxide synthase (PI3K/Akt/eNOS) pathway in HUVEC and the cyclic guanosine monophosphate/cGMP-dependent protein kinase (cGMP/PKG) pathway in VSMC were determined by Western blot. Network pharmacological analysis revealed that the antihypertensive effect of CRTT is closely associated with biological pathways such as vascular tone regulation, adrenergic receptor activation, protein kinase activity and signaling pathways such as the cGMP/PKG signaling pathway, vascular smooth muscle contraction, neuroactive ligand-receptor interaction, adrenergic signaling in cardiomyocytes and calcium signaling pathways. The in vitro study confirmed that CRTT increased the levels of phosphorylated phosphatidylinositol-3-kinase (p-PI3K), phosphorylated protein serine threonine kinase (p-Akt), phosphorylated endothelial nitric oxide synthase (p-eNOS) in HUVEC and the levels of eNOS, phosphorylated vasodilator-stimulated phosphoprotein (p-VASP), and PKG in VSMC through multiple targets and pathways. These results suggest that the activation of PI3K/Akt/eNOS pathway and endothelial-dependent NO/cGMP signaling may be involved in the CRTT-mediated hypotensive effect.

Puerarin protects against myocardial ischemia/reperfusion injury by suppressing NLRP3 inflammasome activation via TLR4/Myd88/NF-κB pathway in rats / 药学学报

This study was to investigate the protective effects of puerarin on myocardial ischemia/reperfusion (MI/R) injury and the underlying mechanism. The MI/R-model was established by ligating the left anterior descending artery (LAD) for 60 min followed by 24 h reperfusion, puerarin (10, 30, and 100 mg·kg-1) was orally administered 20 min before reperfusion. Cardiac function, myocardial infarct index, cardiac damage markers, inflammatory cytokines, and apoptosis index were measured to evaluate the protective effects of puerarin on MI/R injury. The activation of Nod-like receptor protein 3 (NLRP3) inflammasome and Toll like receptor 4 (TLR4)/myeloid differentiation factor 88 (Myd88)/nuclear factor kappa B (NF-κB) pathway were determined by Western blot. All animal experimental procedures were approved by the ethics committee of the Institute of Materia Medica, Peking Union Medical College, Chinese Academy of Medical Sciences. The results showed that puerarin could significantly improve cardiac function, reduce myocardial infarct size, decease the levels of lactic dehydrogenase (LDH), aspartate transaminase (AST), creatine kinase-MB (CK-MB), and cardiac troponin T (cTnT) and suppress cardiomyocyte apoptosis. Meanwhile, puerarin could notably decrease the levels of inflammatory cytokines such as interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis revealed that puerarin could downregulate the expression of TLR4, Myd88, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cleaved-caspase 1, cleaved-gasdermin-D (GSDMD), IL-1β, and IL-18, as well as the phosphorylation levels of inhibitor of NF-κB α (IκBα), IκB kinase β (IKKβ), and NF-κB. These findings demonstrated that puerarin could alleviate MI/R injury by suppressing NLRP3 inflammasome activation, possibly via TLR4/Myd88/NF-κB pathway.

Research progress of natural drugs targeting mitochondrial autophagy against ischemic heart disease / 药学学报

Ischemic heart disease (IHD), which has been considered to be exclusively caused by stenosis or occlusion of coronary artery, is a significant cause of morbidity and mortality worldwide. Mitochondrial dysfunction is the main pathological basis of ischemic heart disease and reperfusion injury, and moderate mitochondrial autophagy can selectively remove damage proteins and organelles to maintain intracellular homeostasis, so mitochondrial autophagy is important for maintaining the homeostasis of cardiomyocytes. Natural drugs from plants are widely used in ischemic heart disease. In recent years, more and more natural drugs have been proven to alleviate myocardial cell damage after ischemia/reperfusion through mitochondrial autophagy. This paper reviews the research progress of natural drugs from plants medicines regulating mitochondrial autophagy in the treatment of ischemia heart disease.

Advances in the pathogenesis of depression based on purinergic system and purine metabolism / 药学学报

Depression was a complex and difficult to regulate disease, which was closely related to purinergic system and purine metabolism disorder. Although there had been studies to improve depression by regulating purinergic system, the mechanism of action was complex and needed to be sorted out. Recently, a large number of studies had found that the addition of exogenous purine metabolites adenosine, inosine and guanosine had a significant antidepressant effect, indicating that regulating the level of purine substances in purine metabolism could also improve depression, which was of great significance to the further study of the pathogenesis and treatment of depression. In view of this, this study reviewed the relationship between purinergic system or purine metabolism and depression, in order to provide a reference for the further study of the pathogenesis of depression.

Mitochondrial retrograde signaling: a new option for the treatment of mitochondrially related diseases / 药学学报

Mitochondria play a key role in cell metabolism. In addition to synthesizing ATP, they also participate in many physiological and pathological processes, including apoptosis, inflammation, oxidative stress, neuronal disease, tumor development, and aging. Most gene transcription of mitochondrial proteins occurs in the nucleus, so the biogenesis of mitochondria and the maintenance of mitochondrial homeostasis mainly depend on the expression of nuclear genes (nDNA) and mitochondria-nucleus interactions. Conversely, mitochondria can affect the expression of nuclear genes through nuclear transcription factors, a process called mitochondrial retrograde signaling. This review summarizes the research progress on mitochondria-nucleus retrograde signaling and its regulation, including the ways by which mitochondria regulate nuclear genes and affect biological processes, and discusses new strategies for the treatment of diseases that involve mitochondrial retrograde signaling in disease pathology.
