Network Pharmacology and in vitro Experimental Verification on Intervention of Oridonin on Non-Small Cell Lung Cancer.

Objective: To explore the key target molecules and potential mechanisms of oridonin against non-small cell lung cancer (NSCLC).

Methods: The target molecules of oridonin were retrieved from SEA, STITCH, SuperPred and TargetPred databases; target genes associated with the treatment of NSCLC were retrieved from GeneCards, DisGeNET and TTD databases. Then, the overlapping target molecules between the drug and the disease were identified.

Phosphorylation Modification, Structural Characterization, Antioxidant and DNA Protection Capacities of Polysaccharides from Asarum Sieboldii Miq.

Polysaccharide from Asarum sieboldii Miq (ASP) was extracted and five phosphorylation polysaccharides with different degree of substitution were obtained, namely ASPP1, ASPP2, ASPP3, ASPP4, and ASPP5 (ASPPs). The physical and chemical structure and biological activities were studied. The results suggested that the carbohydrate and protein content were reduced while uronic acid was increased after phosphorylation modification.

Maternal anti-tumour necrosis factor-α drug use during pregnancy and risk of infection in the offspring: A systematic review and meta-analysis.

Background: Anti-tumour necrosis factor (TNF)-α drugs are used by increasing numbers of reproductive-age women. Although the neonatal outcomes have been described, there are concerns regarding the risk of infection in offspring following exposure to anti-TNF-α.

Methods: A literature search was conducted using Pubmed, EMBASE, and the Cochrane Database, from inception through August 2020.

CRISPR-Cas9 Mediated Genome Editing in .

In recent years, great progress has been made in the research of genome editing systems, one of which is the CRISPR-Cas9 system, a powerful technology that is applied to edit animal genome. Here, we describe a CRISPR-Cas9 mediated mutation protocol for efficiently and specifically editing genes in . In this optimized system, the mutant progeny can be generated by only injecting a DNA plasmid encoding synthetic guide RNA (sgRNA) under the control of the U6b promoter into transgenic fly embryos in which Cas9 is specifically expressed in the progenitor cells, thus the gene of interest can be edited by the CRISPR in germ cells, with high rate of heritable mutations and few side effects.

Measurement of frontal lobe volume and thalamic volume in fetuses with congenital heart disease at different gestational weeks using three dimensional ultra sonography and its clinical value.

Our study aimed to investigate the measurement of frontal lobe volume and thalamic volume in fetuses with congenital heart disease (CHD) at different gestational weeks using three dimensional (3-D) ultrasonography and its clinical value. Then, 238 pregnant women who received obstetric ultrasonography in ultrasound department of Internal Medicine of our hospital were enrolled between March 2013 to April 2014. In this study, 85 fetuses were diagnosed to develop CHD by prenatal fetal echocardiography, and the other 153 fetuses were normal.

Cytotoxic activity, apoptosis induction and structure-activity relationship of 8-OR-2-aryl-3,4-dihydroisoquinolin-2-ium salts as promising anticancer agents.

As our continuing research, a series of 2-aryl-8-OR-3,4-dihydroisoquinolin-2-ium bromides were evaluated for cytotoxic activity on cancer cells and apoptosis induction in the present study. SAR was derived also. Among them, 23 compounds showed the higher cytotoxicity on MKN-45 cells with IC values of 1.

Synthesis, bioactivity and structure-activity relationships of new 2-aryl-8-OR-3,4-dihydroisoquinolin-2-iums salts as potential antifungal agents.

As our continuing research on antifungal dihydroisoquinolin-2-ium salts, forty 2-aryl-8-OR-3,4-dihydroisoquinolin-2-ium bromides were synthesized and characterized by spectroscopic analysis. By using the mycelium growth rate method, the compounds were evaluated for antifungal activity against three plant pathogenic fungi and structure-activity relationships (SAR) were derived. The vast majority of the compounds displayed the medium to high activity with inhibition rates of 50-100% at 150μM.

Design, Synthesis, and Structure--Activity Relationship of New 2-Aryl-3,4-dihydro-β-carbolin-2-ium Salts as Antifungal Agents.

Twenty-two 2-aryl-9-methyl-3,4-dihydro-β-carbolin-2-ium bromides along with four 9-demethylated derivatives were synthesized and characterized by spectroscopic analysis. By using the mycelium growth rate method, the compounds were evaluated for antifungal activities in vitro against six plant pathogenic fungi, and structure-activity relationships (SAR) were derived. Almost all of the compounds showed obvious inhibition activity on each of the fungi at 150 μM.

2-(Substituted phenyl)-3,4-dihydroisoquinolin-2-iums as novel antifungal lead compounds: biological evaluation and structure-activity relationships.

The title compounds are a class of structurally simple analogues of quaternary benzo[c]phenanthridine alkaloids (QBAs). In order to develop novel QBA-like antifungal drugs, in this study, 24 of the title compounds with various substituents on the N-phenyl ring were evaluated for bioactivity against seven phytopathogenic fungi using the mycelial growth rate method and their SAR discussed. Almost all the compounds showed definite activities in vitro against each of the test fungi at 50 μg/mL and a broad antifungal spectrum.
