Predicting the Potentiometric Sensitivity of Membrane Sensors Based on Modified Diphenylphosphoryl Acetamide Ionophores with QSPR Modeling

Membranes, 2022
While potentiometric, plasticized membrane sensors are known as convenient, portable and inexpensive analytical instruments, their development is time- and resource-consuming, with a poorly predictable outcome.

Rescuing Tetracycline Class Antibiotics for the Treatment of Multidrug-Resistant Acinetobacter baumannii Pulmonary Infection

mBio, 2022
Acinetobacter baumannii causes high mortality in ventilator-associated pneumonia patients, and antibiotic treatment is compromised by multidrug-resistant strains resistant to β-lactams, carbapenems, cephalosporins, polymyxins, and tetracyclines.

Potential of Ionophores as A Feed Additive for Sustainable Beef Cattle Production: Review article [PDF]

Journal of Applied Veterinary Sciences
Ionophores are naturally occurring polyether antibiotics that disrupt ion balance in bacterial cells by selectively transporting metal ions across lipid membranes, primarily affecting Gram-positive bacteria in the rumen.

In vitro drug interaction of ionophores with artemisinin and chloroquine against Plasmodium falciparum 3D7 blood-stage infection

Frontiers in Drug Discovery, 2023
The prevalence of clinical resistance of P. falciparum towards artemisinin and its partner drugs has significantly hampered malarial chemotherapy. To circumvent this situation, identifying a new class of partner drugs with significant anti-malarial ...

The Origin of the Non-Constancy of the Bulk Resistance of Ion-Selective Electrode Membranes within the Nernstian Response Range

Membranes, 2021
The dependence of the bulk resistance of membranes of ionophore-based ion-selective electrodes (ISEs) on the composition of mixed electrolyte solutions, within the range of the Nernstian potentiometric response, is studied by chronopotentiometric and ...

A Helical Polypeptide‐Based Potassium Ionophore Induces Endoplasmic Reticulum Stress‐Mediated Apoptosis by Perturbing Ion Homeostasis

Advanced Science, 2019
Perturbation of potassium homeostasis can affect various cell functions and lead to the onset of programmed cell death. Although ionophores have been intensively used as an ion homeostasis disturber, the mechanisms of cell death are unclear and the ...

Unknown Risk on the Farm: Does Agricultural Use of Ionophores Contribute to the Burden of Antimicrobial Resistance?

mSphere, 2019
Ionophores are the second most widely used class of antibiotic in agriculture, with over 4 million kilograms sold in the United States in 2016. Because ionophores are not used in humans, it is widely assumed that their agricultural use will not impact ...
