A Physiologically Based Pharmacokinetic Model for Capreomycin [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2012
ABSTRACTThe emergence of multidrug-resistant tuberculosis (MDR-TB) has led to a renewed interest in the use of second-line antibiotic agents. Unfortunately, there are currently dearths of information, data, and computational models that can be used to help design rational regimens for administration of these drugs.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

A combined in vitro/in silico approach to identifying off-target receptor toxicity [PDF]

open access: yes, 2018
Many xenobiotics can bind to off-target receptors and cause toxicity via the dysregulation of downstream transcription factors. Identification of subsequent off-target toxicity in these chemicals has often required extensive chemical testing in animal ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Physiologically Based Pharmacokinetics Model in Pregnancy: A Regulatory Perspective on Model Evaluation

open access: yesFrontiers in Pediatrics, 2021
Physiologically based pharmacokinetics (PBPK) modelling is widely used in medicine development and regulatory submissions. The lack of clinical pharmacokinetic data in pregnancy is widely acknowledged; therefore, one area of current interest is in the ...

Sex differences in urinary levels of several biological indicators of exposure: a simulation study using a compartmental based toxicokinetic model [PDF]

open access: yes, 2014
Toxicokinetic modeling is a useful tool to describe or predict the behavior of a chemical agent in the human or animal organism. A general model based on four compartments was developed in a previous study in order to quantify the effect of human ...

An introduction to physiologically‐based pharmacokinetic models

open access: yesPediatric Anesthesia, 2016
SummaryPhysiologically‐based pharmacokinetic (PBPK) models represent drug kinetics in one or more ‘real’ organs (and hence require submodels of organs/tissues) and they describe ‘whole‐body’ kinetics by joining together submodels with drug transport by blood flow as dictated by anatomy.
