Abstract
Oxidative stress-induced cardiomyocyte apoptosis was the primary causative factor of cardiovascular disease (CVD). However, the existing therapy drugs for oxidative stress were much less investigated, which underlined the necessity for new drug discovery and development. Herein, we aimed to synthesize several novel idebenone (IDE) derivatives and investigate the protective effect and mechanism of these derivatives against H2O2-induced oxidative stress injury in H9C2 cells by determining cell proliferation rate, detecting the reactive oxygen species (ROS) level, and the expression of related proteins. Additionally, the study also investigated the protective effect of IDE-1 pretreatment on Balb/c mice after hypoxia-reoxygenation. In vivo experiments, the damage to cardiomyocytes was assessed using hematoxylin-eosin (HE) staining and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining. The results showed that IDE-1 possessed the highest antioxidant damage activity among all IDE derivatives, which could notably decrease the levels of intracellular ROS. Furthermore, the antioxidant mechanism was confirmed to be potentially linked to the expression levels of the oxidation-related pathway heme oxygenase-1 (HO-1) and the apoptosis-related pathway Bcl-2/Bax and caspase-3. Our results demonstrated that IDE derivatives could be a new research direction for the treatment of cardiovascular diseases associated with oxidative stress.
期刊介绍：
Frontiers in Chemistry is a high visiblity and quality journal, publishing rigorously peer-reviewed research across the chemical sciences. Field Chief Editor Steve Suib at the University of Connecticut is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to academics, industry leaders and the public worldwide.
Chemistry is a branch of science that is linked to all other main fields of research. The omnipresence of Chemistry is apparent in our everyday lives from the electronic devices that we all use to communicate, to foods we eat, to our health and well-being, to the different forms of energy that we use. While there are many subtopics and specialties of Chemistry, the fundamental link in all these areas is how atoms, ions, and molecules come together and come apart in what some have come to call the “dance of life”.
All specialty sections of Frontiers in Chemistry are open-access with the goal of publishing outstanding research publications, review articles, commentaries, and ideas about various aspects of Chemistry. The past forms of publication often have specific subdisciplines, most commonly of analytical, inorganic, organic and physical chemistries, but these days those lines and boxes are quite blurry and the silos of those disciplines appear to be eroding. Chemistry is important to both fundamental and applied areas of research and manufacturing, and indeed the outlines of academic versus industrial research are also often artificial. Collaborative research across all specialty areas of Chemistry is highly encouraged and supported as we move forward. These are exciting times and the field of Chemistry is an important and significant contributor to our collective knowledge.
