Discovery and characterization of natural products that act as pheromones in fish

open access: yes, 2018
Fish use a diverse collection of molecules to communicate with conspecifics. Since Karlson and Luscher termed these molecules 'pheromones', chemists and biologists have joined efforts to characterize their structures and functions. In particular,

Natural product inspired chiral ligand design: Aloperine induced asymmetric hydroarylation of ketimines under Pd catalysed conditions [PDF]

open access: yes, 2022
A naturally occurring alkaloid aloperine was utilized as a core chiral skeleton for the development of new ligands. Using these chiral 1,3-diamine ligands, a Pd catalysed asymmetric hydroarylation of ketimines was reported.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Triple-helical recombinant humanized type I collagen promotes photodamaged skin repair via ECM remodeling and anti-inflammatory mechanisms

open access: yesCollagen and Leather
Ultraviolet (UV) irradiation is a major cause of photoaging, driving oxidative stress, inflammation, and extracellular matrix (ECM) degradation. Collagen is central to dermal integrity, yet animal-derived sources pose immunogenic and pathogen risks ...
