Substituent Effects on the Reactivity of Cyclic Tertiary Sulfamidates [PDF]

, 2017
The reactivity of cyclic tertiary sulfamidates derived from α-methylisoserine strongly depends on the substitution at the C and N termini. These substrates are one of the very few examples able to undergo nucleophilic ring opening at a quaternary carbon ...

Preparation and Electrochemical Properties of LiCuxMn2-xO4 (x ≤ 0.10) Cathode Material by a Low-Temperature Molten-Salt Combustion Method

International Journal of Electrochemical Science, 2015
Single-phase LiCuxMn2-xO4 cathode materials were prepared by a molten-salt combustion method. Surface morphology and particle size of the synthesized materials were characterized by scanning electron microscopy.

3R-Substituted and Norbornane-Annelated 1H-Phospholanoxides: Synthesis and Structure

Chemistry Proceedings, 2021
A method for the synthesis of 3R-substituted and norbornane-annelated 1H-phospholan oxides has been developed. The method is based on the in situ substitution of the Al atom by the P atom in five-membered cyclic alumolanes using phosphorus trichloride ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Preparation and Double Isomerization Polymerization of Substituted Cyclic Pseudoureas [PDF]

Polymer Journal, 1995
Four cyclic pseudoureas, 2-(2-isoindolinyl)-2-oxazoline (1e), 2-(1,2,3,4-tetrahydroisoquinolin-2-yl)-2-oxazoline (1f), 2-(1-indolinyl)-2-oxazoline (1g) and, 2-(1,3,3-trimethyl-6-azabicyclo[3.2.1]oct-6-yl)-2-oxazoline (1i) were newly prepared. The polymerization of these monomers with methyl trifluoromethanesulfonate gave poly[(N-carbamoylimino)ethylene]

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
