Stereocontrol in Conformationally Stable C(sp2)─C(sp3) Atropisomers

Angewandte Chemie, Volume 137, Issue 28, July 7, 2025.
Building in our expertize in the synthesis of trans‐dihydrobenzofurans via organocatalyzed domino Michael/O‐cyclization between β‐naphthols and nitroalkenes, we developed an efficient strategy to access a new family of atropisomers bearing a conformationally stable C(sp2)─C(sp3) bond and two stereogenic centers through simple and highly ...

Computational Analysis of the Mode of Action of Disopyramide and Quinidine on hERG-Linked Short QT Syndrome in Human Ventricles

Frontiers in Physiology, 2017
The short QT syndrome (SQTS) is a rare cardiac disorder associated with arrhythmias and sudden death. Gain-of-function mutations to potassium channels mediating the rapid delayed rectifier current, IKr, underlie SQTS variant 1 (SQT1), in which treatment ...

In Vitro and Clinical Evaluations of UGT1A1‐, P‐gp‐, OATP1B1‐, and BCRP‐Mediated Drug–Drug Interactions of Belumosudil, a Potent ROCK2 Inhibitor

The Journal of Clinical Pharmacology, EarlyView.
Abstract Belumosudil is an oral selective rho‐associated coiled‐coil containing protein kinase 2 inhibitor, approved as a treatment for chronic graft‐versus‐host disease. Prior clinical studies demonstrated that coadministration with strong CYP3A4 inducers or proton pump inhibitors requires dose modification of belumosudil.

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

Frontiers 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.

Modelling species selectivity in rat and human cytochrome P450 2D enzymes. [PDF]

PLoS ONE, 2013
Updated models of the Rat Cytochrome P450 2D enzymes are produced based on the recent x-ray structures of the Human P450 2D6 enzyme both with and without a ligand bound. The differences in species selectivity between the epimers quinine and quinidine are

Role of pharmacotherapy in Brugada syndrome [PDF]

, 2004
In patients who undergo aborted sudden cardiac death or syncope of unknown origin (symptomatic Brugada syndrome), no one argues that the implantation of an ICD is the first-line therapy regardless of the findings of the EP study.

Dextromethorphan versus Dextrorphan: A Quantitative Comparison of Antitussive Potency following Separate Administration of Metabolite

The Journal of Clinical Pharmacology, EarlyView.
Abstract To assess the antitussive effects of dextrorphan (DOR) relative to its parent compound, dextromethorphan (DEX) a double‐blind, randomized, placebo‐controlled crossover study was conducted in 23 healthy volunteers using citric acid cough challenge test after administering placebo, DEX, or DOR.

Quinidine Therapy for Lennox-Gastaut Syndrome With KCNT1 Mutation. A Case Report and Literature Review

Frontiers in Neurology, 2019
Mutations in the Potassium channel subfamily T member 1 (KCNT1) gene have been reported in a range of epileptic encephalopathies. Here we report the case of a 12-year-old male suffering from multiple types of epileptic seizures and cognitive decline from
