LncDARS‐AS1 Regulates ATP1A1 Stability and Enhances Na+/K+ ATPase Activity to Promote Osteosarcoma Metastasis

Advanced Science, EarlyView.
This study identifies LncDARS‐AS1 as a novel oncogenic regulator that stabilizes ATP1A1 and enhances Na⁺/K⁺ ATPase activity, promoting osteosarcoma metastasis. Targeting the LncDARS‐AS1/ATP1A1/NKA axis, including pharmacological inhibition with digoxin, offers promising opportunities for the development of new therapeutic strategies against ...

Size‐Selective Functionalization of Sugars and Polyols Using Zeolites for Renewable Surfactant Production

Angewandte Chemie, EarlyView.
A zeolite‐catalyzed strategy enables size‐selective monoacetalization of sugars and polyols in a single step by leveraging pore confinement to distinguish between mono‐ and multi‐substituted species. This broadly applicable method avoids protection steps and excess reagents, opening new routes to bio‐based amphiphiles with strong surface activity and ...

Expanding a fluorescent RNA alphabet: synthesis, photophysics and utility of isothiazole-derived purine nucleoside surrogates. [PDF]

, 2017
A series of emissive ribonucleoside purine mimics, all comprised of an isothiazolo[4,3-d]pyrimidine core, was prepared using a divergent pathway involving a key Thorpe-Ziegler cyclization.

Cyanogenic glycosides in plants [PDF]

Brazilian Archives of Biology and Technology, 2000
The presence of cyanogenic glycosides was determined in 70 plant species from the campus of the State University of Londrina, PR, Brazil, and a further 45 plant species from the Forestry Reserve on the Doralice Farm in Ibiporã, PR, Brazil. Of the vegetative species from the State University of Londrina, 7.1% showed cyanogenic glycosides: Manihot ...

Superelastic Fire‐Safe Aerogel with Hierarchical Structures via Dual Templates Aided by Microbubble Engineering

Advanced Science, EarlyView.
Here, a dual‐template strategy (ice and bubble template) is used to prepare fire‐safe aerogels with hierarchical structures. When the foam expansion ratio exceeds the jamming transition value in the foam system, the aerogels demonstrate superelasticity and extreme shape adaptability.

Synthesis, Conformal Analysis, and Antibody Binding of Staphylococcus aureus Capsular Polysaccharide Type 5 Oligosaccharides

Angewandte Chemie, EarlyView.
A set of conjugation‐ready Staphylococcus aureus serotype 5 oligosaccharides has been generated using a stereoselective [3 + 3n] glycosylation strategy. The structures differ in chain length (up to three repeating units) and O‐ and N‐acetylation pattern.

Engineered Fusion Enzyme‐Mediated Non‐Consecutive Cyclization‐Glycosylation Enables Heterologous Synthesis of Antifungal Enfumafungin

Advanced Science, EarlyView.
The artificial biosynthetic pathway potentially involved in biosynthesis of enfumafungin is first reconstructed in an optimized Aspergillus oryzae chassis with the increased site‐specific integration efficiency and shortened time for marker recycling, which requires an artificial fusion enzyme EfuA(TC)FsoA(GT).

Effects of 5-azaC on Iridoid Glycoside Accumulation and DNA Methylation in Rehmannia glutinosa

Frontiers in Plant Science, 2022
Iridoid glycoside is the important secondary metabolite and the main active component in Rehmannia glutinosa. However, the mechanisms that underlie the regulation of iridoid glycoside biosynthesis remain poorly understood in R. glutinosa.
