Summary: This study reveals that COVID-19 patients of all age groups experience GSH deficiency, increased OxS, and elevated oxidant damage, which worsen with advancing age. The supplementation of GlyNAC, a combination of glycine and N-acetylcysteine, has the potential to improve these defects and combat COVID-19 infection.

Summary: The review summarizes successful fragment-to-lead studies published in 2020 and discusses trends and best practices in fragment libraries, target proteins, screening technologies, hit-optimization strategies, and properties of hit fragments and leads. Trends and innovations identified in the review promise to further increase the success of FBDD by developing novel screening fragments, improving screening technologies, using computer-aided design and virtual screening, and combining FBDD with other drug-discovery technologies.

Summary: Type 2 diabetes is a redox disease characterized by oxidative stress and chronic inflammation. The cardiac manifestations of the disease, known as diabetic cardiomyopathy, are primarily caused by mitochondrial overproduction of reactive oxygen species. These species are produced due to intracellular hyperglycemia, increased fatty oxidation, and lipotoxicity in cardiomyocytes. The resulting oxidative distress affects various pathways, leading to cell dysfunction and injury. Animal studies have shown that increasing the expression of antioxidant enzymes can attenuate myocardial pathology and improve cardiac function.

Summary: This article introduces the definition and generation pathways of Reactive Oxygen Species (ROS), as well as their role in the development of cancer. ROS can act as tumor-suppressing or tumor-promoting agents, and their increased levels can inhibit tumor growth or induce apoptosis. However, high levels of ROS can also lead to the formation of malignant tumors.

Summary: The exciton chirality method is a well-established approach for assigning the absolute configuration of compounds with multiple chromophores. Its correct application requires a good understanding of molecular conformation, transition dipole moment directions, and the exciton coupling mechanism. These prerequisites can be easily verified through quantum-mechanical calculations.

Summary: This article reviews the potential applications of carnosic acid (CA) and carnosol (CS) in rosemary for conditions such as Alzheimer's disease, Parkinson's disease, and COVID-19. It highlights the antioxidant, anti-inflammatory, and neuroprotective effects of CA, as well as its potential to inhibit the NLRP3 inflammasome. The article suggests that CA-related compounds could serve as therapeutics for acute and chronic neurological effects caused by SARS-CoV-2 infection and other neurodegenerative diseases.

Summary: A new chamigrane sesquiterpene, albocimea A (1), and one known compound, 6-hydroxy-8-methoxy-3S,5-dimethylisochroman (2), were isolated from the rice fermentation of the fungus Antrodiella albocinnamomea. The structure of the new compound was elucidated through spectroscopic analysis and ECD calculations. Cytotoxicity tests on both compounds against five human cancer cell lines revealed no significant cytotoxicity.

Summary: More studies are needed to develop new drugs that can overcome drug resistance and minimize side effects. Quercetin, a natural flavonoid, has shown diverse biological activities, but its poor solubility and bioavailability limit its applicability. Researchers have been exploring the modification of quercetin by designing and synthesizing novel derivatives to overcome these limitations. The physico-chemical properties of quercetin's molecular scaffold make it attractive for drug development, and the investigation of its derivatives' activities, chemical structure-activity relationship, and mechanism of action is crucial. Quercetin-based molecules have the potential to contribute to the discovery of medications for various diseases.
