2α-Acetoxy-15-acetylartemisiifolin, a new Anti-trypanosomal Sesquiterpene Lactone from Mikania guaco [PDF]
, 2017 ArticleMikania guaco Bonpl. methanol extract showed an interesting activity against Trypanosoma cruzi with an IC50 of 4 μg/mL. Bioassay-guided fractionation of the methanol extract resulted in the isolation of a new sesquiterpene lactone, 2α-acetoxy,15 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Natural Product Primary Sulfonamides and Primary Sulfamates [PDF]
, 2015 Primary sulfonamide and primary sulfamate functional groups feature prominently in the structures of U.S. FDA-approved drugs. However, the natural product chemical space contains few examples of these well-known zinc-binding chemotypes, with just two ...

Amyloid as a natural product [PDF]
The Journal of Cell Biology, 2003 Amyloid fibrils, such as those found in Alzheimer's and the gelsolin amyloid diseases, result from the misassembly of peptides produced by either normal or aberrant intracellular proteolytic processing. A paper in this issue by Marks and colleagues (Berson et al., 2003) demonstrates that intra-melanosome fibrils are formed through normal biological ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Natural Product Reports, 2018 This review of 2016 literature describes the structures and biological activities of 1277 new marine natural products and the structure revision and absolute configuration of previously reported MNPs. The chemical diversity of 28 609 MNPs reported since 1957 is also investigated and compared to that of approved drugs.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
