Solvent Effects on the Conformational Preferences of 2,6‐Pyridylcarboxamide Foldamers

Chemistry – A European Journal, EarlyView.
The marked effect of organic solvents and water/methanol mixtures on the conformational preferences of a soluble chiral foldamer has been established in a diverse array of seventeen distinct environments. ABSTRACT The marked influence of organic solvents and water on the conformational preferences of a chiral, soluble 2,6‐pyridylcarboxamide foldamer ...

Tetradecanuclear {Ni9Ln5} Clusters Featuring Encapsulated {Ln5} Trigonal Bipyramids: Modular 3d‐4f Architectures With Broad‐Range Magnetocaloric Response

Chemistry – A European Journal, EarlyView.
The use of 2‐aminoisobutyric acid in 3d–4f chemistry affords three {Ni₉Ln5} clusters, with the Gd analogue exhibiting an unusually broad magnetocaloric effect across an extended temperature range. ABSTRACT The solvothermal reaction between Ni(HCOO)2.2H2O, 2‐aminoisobutyric acid (aibH), Ln(OAc)3·4H2O (Ln = Gd, Y, Dy) and NEt3 in MeOH/MeCN affords the ...

Pertussis toxin nullifies the depolarisation of the membrane potential and the stimulation of the rapid phase of 45Ca2+ entry through L-type calcium channels that are produced by follicle stimulating hormone in 10- to 12-day-old-rat Sertoli cells.

Frontiers in Physiology, 2010
The aim of this study was to evaluate the effect of pertussis toxin (PTX) on the depolarising component of the action of FSH on the membrane potential of Sertoli cells, which is linked to the rapid entry of Ca2+ into cells and to the Ca2+-dependent ...

Recent data on obesity research: β-aminoisobutyric acid

Bratislava Medical Journal, 2014
The world-wide epidemic of obesity is now affecting up to a third of the adult population. Research attempting to contribute to management of this health scourge has been recently refocused on the essential role of physical activity. Muscle activity induces a dramatic increase in transcription of the peroxisome proliferator-activated receptor gamma ...

Peptide Marriages: Modular Assembly of Multi‐Agonist Therapeutics

Chemistry – A European Journal, EarlyView.
A modular polyethylene glycol (PEG) scaffold enables rapid assembly of dual peptide agonists using strain‐promoted azide–alkyne cycloaddition (SPAAC) and copper‐catalysed azide–alkyne cycloaddition (CuAAC). Glucagon‐like peptide‐1 (GLP‐1) and amylin agonists were combined with controlled valency, yielding low‐picomolar activity and receptor‐selective ...

Composite membranes comprising of polymeric and molecular amines embedded in poly(vinyl alcohol) matrices to facilitate CO2/H2 separation

The Canadian Journal of Chemical Engineering, EarlyView.
Polymeric and molecular amines embedded in hygroscopic matrices to facilitate CO2 transport for CO2/H2 separation. Abstract This work dealt with composite membranes comprising of polyvinylamine (PVAm) and triethylenetetramine (TETA) embedded in poly(vinyl alcohol) (PVA) for CO2/H2 separation via facilitated transport of CO2, where polymeric and ...

Properties of α-Aminoisobutyric Acid Transport in a Thermophilic Microorganism [PDF]

Journal of Bacteriology, 1974
Uptake of α-aminoisobutyric acid (AIB) by a leucine-tyrosine auxotroph of a thermophilic microorganism starved for leucine was studied. AIB was taken up by the cells against a substantial concentration gradient (300:1) and was present there in a free and unchanged form.

β‐Aminoisobutyric Acid Alleviates Cisplatin‐Induced Muscle Atrophy by Regulating E3 Ubiquitin Ligases, Apoptosis, Amino Acid Metabolism, Autophagy, and Ferroptosis

Medicine Bulletin, EarlyView.
ABSTRACT Background Cisplatin (CIS) is a widely used broad‐spectrum anticancer agent, but its clinical application is often limited by severe adverse effects, including skeletal muscle atrophy, which compromises patients' quality of life and treatment efficacy.
