Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Efficacy and Limitations of Quinidine in Patients with Brugada Syndrome

open access: yes, 2019
Background Quinidine at high dose is suggested as antiarrhythmic treatment in patients with Brugada Syndrome (BrS), but its efficacy to prevent life-threatening arrhythmic events (LAE) in this population is unproven and its use limited by frequent side ...

Quinoline Alkaloids in Suspension Cultures of Cinchona ledgeriana Treated with Various Substances

open access: yesHayati Journal of Biosciences, 2010
Cinchona alkaloids are in extensive uses, not only for drugs but also for soft drink industries. They are harvested from the bark of trees Cinchona spp. after certain ages and therefore are available over a limited time.

In silico Assessment of Pharmacotherapy for Human Atrial Patho-Electrophysiology Associated With hERG-Linked Short QT Syndrome

open access: yesFrontiers in Physiology, 2019
Short QT syndrome variant 1 (SQT1) arises due to gain-of-function mutations to the human Ether-à-go-go-Related Gene (hERG), which encodes the α subunit of channels carrying rapid delayed rectifier potassium current, IKr.

Computational prediction of drug response in short QT syndrome type 1 based on measurements of compound effect in stem cell-derived cardiomyocytes.

open access: yesPLoS Computational Biology, 2021
Short QT (SQT) syndrome is a genetic cardiac disorder characterized by an abbreviated QT interval of the patient's electrocardiogram. The syndrome is associated with increased risk of arrhythmia and sudden cardiac death and can arise from a number of ion

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Subunit-specific inhibition of inward-rectifier K+ channels by quinidine

open access: yes, 1995
Distinct inward-rectifier K+ channel subunits were expressed in Xenopus oocytes and tested for their sensitivity to the channel blocker quinidine. The ‘strong’ inward-rectifier K+ channel IRK1 was inhibited by quinidine with an EC50 of 0.7 mM, while the ‘

A review Commentary on Quinidine kinetics (PK modelling)

open access: yes, 2020
This article takes you through the possible pharmacokinetic models and parameters for the antiarrhythmic drug Quinidine. The shuffle between the linear and non-linear pharmacokinetics of quinidine make it a candidate for therapeutic drug monitoring.

Drug Critical Limits for Urgent Physician Notification

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 178-192, July 2026.
Critical limits represent quantitative decision thresholds for drugs that require immediate clinician notification and potential life‐saving intervention. United States hospitals lack a national standard for drug critical limits. We collected critical limits from 417 US hospitals across all 50 states and Washington, D.C.; of these, 411 maintained drug ...
