Structurally diverse phthalides from fibrous roots of Ligusticum chuanxiong Hort. and their biological activities.

Falonolide A (1) and B (2), two novel polyyne hybrid phthalides resulting from unprecedented carbon skeleton polymerized by Z-ligustilide and falcarindiol, along with six new related phthalides (3-8), were isolated from Ligusticum chuanxiong Hort. Their structures were elucidated by spectroscopic analysis, computer-assisted structure elucidation (CASE) analysis, DP4+ probability analysis and electronic circular dichroism (ECD) calculations. A plausible biosynthetic pathway for 1-8 was proposed, and the production mechanism of 2 was revealed by density functional theory (DFT) method.

Relationship Between Knowledge Base and Innovation-Driven Growth: Moderated by Organizational Character.

On the background of innovation-driven growth strategy of the Chinese government, this study aims to explore the impact of the knowledge base on innovation-driven growth of a firm, which is moderated by organizational character. Based on the data of 965 Chinese listed companies, some hypotheses were tested using the method of hierarchical regression analysis. Organizational growth relies on both technological and business model innovations and their interactive effect.

Review of Natural Resources With Vasodilation: Traditional Medicinal Plants, Natural Products, and Their Mechanism and Clinical Efficacy.

For decades, chronic diseases including cardiovascular and cerebrovascular diseases (CCVDs) have plagued the world. Meanwhile, we have noticed a close association between CCVDs and vascular lesions, such as hypertension. More focus has been placed on TMPs and natural products with vasodilation and hypotension.

Chuanxiongdiolides R4 and R5, phthalide dimers with a complex polycyclic skeleton from the aerial parts of Ligusticum chuanxiong and their vasodilator activity.

Chuanxiongdiolides R4-R6 (1-3), three novel phthalide dimers featuring two classes of unreported monomeric units (ligustilide/senkyunolide A and ligustilide/neocnidilide) with an unprecedented linkage style (3a,7'/7a,7'a), were isolated from the aerial parts of Ligusticum chuanxiong, together with three pairs of enantiomeric phthalide dimers [(-)/(+)-4a/4b, 5a/5b, and 6a/6b]. The bioassays revealed that compounds 1, 3, 4, 5, and 6 showed significant vasodilation effects, and the mechanism may be attributed to Ca1.2 activation blockade.

Effect of Repaglinide on Blood Glucose, Endothelial Function, Lipid Metabolism, and Inflammatory Reaction in a Rat Model of Atherosclerosis.

Objective: To investigate the protective effect of repaglinide on rat with atherosclerosis.

A new abietane diterpenoid from Ajuga ovalifolia var. calantha induces human lung epithelial A549 cell apoptosis by inhibiting SHP2.

The Src-homology 2 domain-containing phosphatase 2 (SHP2), encoded by PTPN11, has been reported oncogenic tyrosine phosphatase associated with various tumors and played critical roles in many cell signaling events. Targeting SHP2 by small molecules may be a promising way for cancer therapy. Herein, a new abietane diterpenoid, named 3-acetoxylteuvincenone G (3-AG), was isolated from the whole plants of Ajuga ovalifolia var.

Modulation of the 5-HTA receptor current by desacylbaldrinal.

The serotonin (5-hydroxytryptamine) type 3 receptor is an important target in the control of digestive dysfunction such as anorexia and bulimia, and 5-HT receptor antagonists are effective against eating disorder and the early-phase chemotherapy and radiotherapy evoked vomiting. Our previous research of revealed the presence of iridoids, which showed potent antitumor activities. Here, we explored the effects of 10π aromatic iridoid desacylbaldrinal isolated from on the 5-HT receptor current.

miR-346 promotes migration and invasion of nasopharyngeal carcinoma cells via targeting BRMS1.

The aim of this study is to determine the expression and roles of miR-346 in nasopharyngeal carcinoma (NPC). We showed that miR-346 was upregulated in NPC tissues compared with adjacent non-tumorous nasopharyngeal tissues. Inhibition of miR-346 significantly attenuated the migration and invasion of NPC cells.

Expression of proteinase-activated receptor (PAR)-2 in monocytes from allergic patients and potential molecular mechanism.

Serine proteases play an important role in inflammation via PARs. However, little is known of expression levels of PARs on monocytes of allergic patients, and influence of serine proteases and PARs on TNF-α secretion from monocytes. Using quantitative real-time PCR (qPCR) and flowcytometry techniques, we observed that the expression level of PAR-2 in monocytes of patients with allergic rhinitis and asthma was increased by 42.

Controlled bile acid exposure to oesophageal mucosa causes up-regulation of nuclear γ-H2AX possibly via iNOS induction.

Using an in vitro model in which flatmounts of oesophagus was periodically exposed to bile acids, we demonstrate, using multiple methods, that the bile acid receptor TGR5, inducible nitric oxide synthase (iNOS) and γ-histone family 2A variant (γ-H2AX) are up-regulated. This indicates that bile acids cause up-regulation of iNOS, which further causes genotoxic stress as evidenced by increase of the highly sensitive marker, phosphorylated histone. In vitro nitric oxide (NO) assays showed increased production of nitric acid in the oesophageal epithelium exposed to the bile acids.

Correlation of IL-18 with Tryptase in Atopic Asthma and Induction of Mast Cell Accumulation by IL-18.

Interleukin- (IL-) 18 and tryptase were previously reported to relate to asthma, but the correlation between these two potent proinflammatory molecules in asthma and their roles in mast cell accumulation remain uninvestigated. Using flow cytometric analysis technique and ovalbumin- (OVA-) sensitized mouse model, it was found that IL-18 and tryptase levels in the plasma of moderate and severe asthma were elevated, and they correlated well with each other. Tryptase and agonist peptides of protease activated receptor- (PAR-) 2 induced substantial quantity of IL-18 release.

Simultaneous analysis of dopamine and homovanillic acid by high-performance liquid chromatography with wall-jet/thin-layer electrochemical detection.

Wall-jet/thin-layer amperometric electrochemical detection (ECD) coupled with high-performance liquid chromatography (HPLC) was used here for the simultaneous analysis of dopamine (DA) and homovanillic acid (HVA) at a glassy carbon electrode. Compared with the conventional thin-layer mode and wall-jet mode, the presented wall-jet/thin-layer ECD has the advantages of enhanced capture of electroactive DA and HVA on the working electrode to give enhanced responses and more convenient washing/refreshment of the working electrode surface. Under optimized conditions, the HPLC-ECD calibration curves show good linearity from 0.
