AI Article Synopsis
- The paper describes the synthesis of 16 new compounds based on noricumazole A from a myxobacterium, focusing on specific chemical modifications.
- These compounds were tested for their ability to inhibit the hepatitis C virus, with most showing moderate to strong inhibitory effects, but also significant cytotoxicity.
- One specific thiazole derivative stands out as a potential lead compound due to its strong antiviral activity and lower toxicity, indicating a better therapeutic profile.
Article Abstract
The total synthesis of 16 new ion channel inhibitors derived from noricumazole A, a secondary metabolite from the myxobacterium Sorangium cellulosum, is reported. Particular focus of library design is put on stereochemical permutations in the central region (C9 and C11), the oxazole moiety and the side chain at C4 of the isochromanone moiety. Noricumazole A and all new noricumazole derivatives were tested in an assay system with inhibitory effect on the hepatitis C virus (HCV) life cycle. Most of them are moderate to strong HCV inhibitors (350 nM-6 nM) but also exert pronounced cytotoxicity. In contrast, the thiazole analogue of noricumazole A is a strong HCV inhibitor with only moderate cytotoxic property. It may become a lead structure with a good therapeutic index (CC(50)/IC(50)) of greater than 10.

Skeletal muscle oxidative capacity related to intramyocellular lipid in young but not in older individuals.

Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

Background And Aims: Radiological imaging is crucial for diagnosing and monitoring patients with inflammatory bowel diseases (IBD). With increasing awareness of radiation risks, imaging doses should be 'as low as reasonably achievable', with a risk level that one should try to stay underneath 75 mSv. However, real-world data on cumulative exposure are limited.

Background: The iAide2 (Tokai) physical activity monitoring system includes diverse measurements and wireless features useful to researchers. The iAide2's sleep measurement capabilities have not been compared to validated sleep measurement standards in any published work.
Objective: We aimed to assess the iAide2's sleep duration and total sleep time (TST) measurement performance and perform calibration if needed.
Fluoride Exposure and Children's IQ Scores: A Systematic Review and Meta-Analysis.
JAMA Pediatr
January 2025
Division of Translational Toxicology, National Institute of Environmental Health Sciences, National Institutes of Health, Research Triangle Park, North Carolina.
Importance: Previous meta-analyses suggest that fluoride exposure is adversely associated with children's IQ scores. An individual's total fluoride exposure comes primarily from fluoride in drinking water, food, and beverages.
Objective: To perform a systematic review and meta-analysis of epidemiological studies investigating children's IQ scores and prenatal or postnatal fluoride exposure.
