Synthesis and cytotoxic activity of ethyl ferulate derivatives as potent anti-inflammatory agents.

While a range of pharmacological agents are currently used to alleviate inflammation, the clinical administration of many of these anti-inflammatory drugs is associated with high rates of adverse side effects that make them poorly suited to long-term use. Therefore, there is a critical need for the development of novel anti-inflammatory agents. Natural compounds and derivatives like ethyl ferulate have risen to prominence as a foundation for many drug discovery efforts owing to their structural diversity and wide-ranging biological activities.

mAexpress-Reader: Prediction of mA regulated expression genes by integrating mA sites and reader binding information in specific- context.

N-methyladenosine (mA) is the most abundant form of mRNA modification and plays an important role in regulating gene expression. However, the mechanisms of mA regulated gene expression in cell or condition specific, are still poorly understood. Even though, some methods are able to predict mA regulated expression (mA-reg-exp) genes in specific context, they don't introduce the mA reader binding information, while this information can help to predict mA-reg-exp genes and more clearly to explain the mechanisms of mA-mediated gene expression process.

Nano-enabled delivery of EGCG ameliorates silica-induced pulmonary fibrosis in rats.

Silicosis is the most serious occupational pulmonary fibrosis caused by excessive inhalation of silica particles, whereas viable therapeutic choices are constrained.

The anti-inflammatory activities assay demonstrated that compound 5b suppressed the expression of pro-inflammatory cytokines including IL-6, TNF-α and NO, it also suppressed the expression of iNOS and COX-2 in LPS-induced RAW264.7 cells in a dose-dependent manner.

Design and Synthesis of New Benzo[d]oxazole-Based Derivatives and Their Neuroprotective Effects on β-Amyloid-Induced PC12 Cells.

A series of novel synthetic substituted benzo[d]oxazole-based derivatives (-) exerted neuroprotective effects on β-amyloid (Aβ)-induced PC12 cells as a potential approach for the treatment of Alzheimer's disease (AD). In vitro studies show that most of the synthesized compounds were potent in reducing the neurotoxicity of Aβ-induced PC12 cells at 5 μg/mL. We found that compound was non-neurotoxic at 30 μg/mL and significantly increased the viability of Aβ-induced PC12 cells at 1.

Corosolic Acid Attenuates Hepatic Lipid Accumulation and Inflammatory Response via AMPK/SREBPs and NF-B/MAPK Signaling Pathways.

Corosolic acid (CA) is the main active component of and has been known to serve as several different pharmacological effects, such as antidiabetic, anti-oxidant, and anticancer effects. In this study, effects of CA on the hepatic lipid accumulation were examined using HepG2 cells and tyloxapol (TY)-induced hyperlipidemia ICR mice. CA significantly inhibited hepatic lipid accumulation via inhibition of SREBPs, and its target genes FAS, SCD1, and HMGCR transcription in HepG2 cells.

Bone marrow mesenchymal stem cells modified by angiogenin-1 promotes tissue repair in mice with oxygen-induced retinopathy of prematurity by promoting retinal stem cell proliferation and differentiation.
