β-aminoisobutyrics acid, a metabolite of BCAA, activates the AMPK/Nrf-2 pathway to prevent ferroptosis and ameliorates lung ischemia-reperfusion injury

Molecular Medicine, 2023
Background Lung ischemia-reperfusion (I/R) injury is a serious clinical problem without effective treatment. Enhancing branched-chain amino acids (BCAA) metabolism can protect against cardiac I/R injury, which may be related to bioactive molecules ...

Alpha-aminoisobutyric acid uptake in primary cultures of astrocytes [PDF]

Neurochemical Research, 1982
Homotypically pure cultures of rat brain astrocytes were used to examine some aspects of non-neuronal A-system (alanine preferring) amino acid uptake. The A-system specific probe, alpha-aminoisobutyric acid is transported rapidly, and a steady state distribution ratio of 9-25 is reached after 30 minute incubations. Kinetic estimates derived from uptake

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 ...

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 ...

Quantum chemical study of molecular properties of small branched-chain amino acids in water

Amino Acids
Four aliphatic amino acids—α-aminobutyric acid (AABA), β-aminobutyric acid (BABA), α-aminoisobutyric acid (AAIBA) and β-aminoisobutyric acid (BAIBA) were investigated in water as a solvent by two quantum chemical methods.

A Novel Lipopeptaibol Emericellipsin A with Antimicrobial and Antitumor Activity Produced by the Extremophilic Fungus Emericellopsis alkalina

Molecules, 2018
Soil fungi are known to contain a rich variety of defense metabolites that allow them to compete with other organisms (fungi, bacteria, nematodes, and insects) and help them occupy more preferential areas at the expense of effective antagonism.

Anion‐Selective Channels Formed by Synthetic 13‐Mer Chimeric α ‐Peptide‐Oligourea Foldamers

Chemistry – A European Journal, EarlyView.
Synthetic 13‐mer α‐peptide‐oligourea chimeric foldamers self‐assemble into supramolecular ion channels, demonstrating high ion transport activity with distinct anion selectivity in lipid membranes. This study supports the design of bioinspired functional foldamer‐based channels for synthetic ion transport applications.

Advances in the Protective Effects and Mechanisms of β‐Aminoisobutyric Acid in Maintaining Multi‐Organ Homeostasis

Medicine Bulletin, EarlyView.
ABSTRACT β‐Aminoisobutyric acid (BAIBA) is an exercise‐responsive myokine/metabolite released by skeletal muscle and has attracted increasing interest as a potential exercise mimetic and therapeutic candidate in preclinical research. BAIBA acts locally in skeletal muscle and can also reach distal organs through the circulation, contributing to the ...
