The effects of anions on sodium transport [PDF]

open access: yesBritish Journal of Pharmacology, 1969
Substitution of chloride by isethionate reduces the short circuit current (SCC) and increases the potential of isolated frog skin. In sodium isethionate Ringer antidiuretic hormone and choline chloride increase the SCC, whereas theophylline is ineffective.

Picrotoxin Delineates Different Transport Configurations for Malate and γ Aminobutyric Acid through TaALMT1

open access: yesBiology, 2022
Plant-derived pharmacological agents have been used extensively to dissect the structure–function relationships of mammalian GABA receptors and ion channels. Picrotoxin is a non-competitive antagonist of mammalian GABAA receptors.

Monitoring Cl- movement in single cells exposed to hypotonic solution [PDF]

open access: yes, 2005
Self-referencing ion--selective electrodes (ISEs), made with Chloride Ionophore I-Cocktail A (Fluka), were positioned 1-3 microm from human embryonic kidney cells (tsA201a) and used to record chloride flux during a sustained hyposmotic challenge. The ISE

Small molecule anionophores promote transmembrane anion permeation matching CFTR activity

open access: yesScientific Reports, 2018
Anion selective ionophores, anionophores, are small molecules capable of facilitating the transmembrane transport of anions. Inspired in the structure of natural product prodigiosin, four novel anionophores 1a-d, including a 1,2,3-triazole group, were ...

Cellular Physiology and Pathophysiology of EAAT Anion Channels

open access: yesFrontiers in Cellular Neuroscience, 2022
Excitatory amino acid transporters (EAATs) optimize the temporal resolution and energy demand of mammalian excitatory synapses by quickly removing glutamate from the synaptic cleft into surrounding neuronal and glial cells and ensuring low resting ...

CryoEM structures of anion exchanger 1 capture multiple states of inward- and outward-facing conformations

open access: yesCommunications Biology, 2022
CryoEM structures and computational modeling of bovine anion exchanger 1 in both inward and outward facing conformations reveal an elevator-like mechanism of ion transport by a solute carrier ion transport family 4 member.

Catechols as Membrane Anion Transporters [PDF]

open access: yesJournal of the American Chemical Society, 2009
We report that an amphiphilic bis-catechol (3) functions as a transmembrane anion transporter. Activity depends on the catechol's substitution and amphiphilicity. We also describe a liposomal assay that allows one to readily measure anion transport selectivity.

Molecular Mechanism of Ochratoxin A Transport in the Kidney

open access: yesToxins, 2010
The mycotoxin, ochratoxin A (OTA), is thought to be responsible for Balkan endemic nephropathy. OTA accumulates in several tissues, especially in the kidneys and liver.

Prediction of human drug clearance and anticipation of clinical drug-drug interaction potential from in vitro drug transport studies [PDF]

open access: yes, 2014
A major concern in drug development is the characterization of new molecular entities (NMEs) with respect to their safety and efficacy. Both factors are determined by the drug’s exposure within the body which itself is affected by drug clearance ...
