The Inhibitory Effect Of Quercetin-3-Glucuronide On Pulmonary Injury In Vitro And In Vivo, Pei-Rong Yua, Jen-Ying Hsu, Chiao-Yun Tseng, Jing-Hsien Chen, Hui-Hsuan Lin
Journal of Food and Drug Analysis
Pulmonary injury is defined as a progressive inflammation. Extensive pro-inflammatory cytokines are secreted from alveolus, associated with the production of reactive oxygen species (ROS) and apoptosis. The model of endotoxin lipopolysaccharide (LPS)-stimulated lung cells has been applied to mimic the pulmonary injury. Some antioxidants and anti-inflammatory compounds can be used as chemopreventive agents of pulmonary injury. Quercetin-3-glucuronide (Q3G) has been showed to exert antioxidant, anti-inflammatory, anti-cancer, anti-aging and anti-hypertension effects. The aim of the study is to examine the inhibitory potential of Q3G on pulmonary injury and inflammation in vitro and in vivo. Firstly, human lung fibroblasts MRC-5 cells pre-treated …

Journal of Food and Drug Analysis
Green emission carbon dots (CDs) electrochemically prepared from 2,6-pyridinedicarboxylic acid and o-phenylenediamine were applied separately for the quantitation of hypochlorite and carbendazim. The characteristic and optical properties of the CDs were studied through fluorescence, UV–vis absorption, X-ray photoelectron spectroscopy, and transmission electron microscopy. The synthesized CDs were mainly 0.8–2.2 nm in size, with an average size of 1.5 nm. The CDs exhibited green luminescence centered at 520 nm when excited by 420 nm light. The green emission of the CDs is quenched after the addition of hypochlorite, mainly through the redox reaction between hypochlorite and hydroxyl groups on the CDs …

Journal of Food and Drug Analysis
Recent rapid development of cancer therapy has come about with the paradigm shift from the traditional goal of targeting cancer cells themselves, to reprograming the immune tumor microenvironment. Accumulating evidence shows that compounds that target epigenetic regulation, called epidrugs, play a crucial role in mediating the immunogenicity of cancer cells and in reshaping antitumor immunity. A large body of literature has recognized natural compounds as epigenetic modulators for their immunomodulatory effects and anticancer potential. Unifying our understanding of the role of these biologically active compounds in immuno-oncology may open new avenues for more effective cancer therapies. In this review, we …
