Therapeutic‐dose verapamil‐induced cardiogenic shock in an older patient: a case report

open access: yesJournal of Pharmacy Practice and Research, EarlyView.
Abstract Background Calcium channel blocker (CCB) toxicity most commonly follows deliberate overdose. However, severe toxicity at therapeutic doses may occur in susceptible individuals. Severe CCB toxicity often presents with clinical features of bradycardia, hypotension, hyperglycaemia, and lactic acidosis.

Conformation of 1,4‐dihydropyridine — planar or boat‐like? [PDF]

open access: yesFEBS Letters, 1988
The geometry of the 1,4‐dihydropyridine molecule was completely optimized employing three different ab initio basis sets (6–31 G*, 4–31 G, STO—3G). The most reliable 6–31G* basis set provides a very flat boat conformation which may easily undergo defolding to a planar ring arrangement.

Scaffold Hopping Provides Liver X Receptor Agonist With Preference for the β Subtype

open access: yesChemMedChem, Volume 21, Issue 19, 14 October 2026.
A scaffold hopping strategy was pursued to enhance the binding pocket engagement and β‐subtype selectivity of liver X receptor agonist 2. The resulting spirocyclic lead compound, (S)‐7, demonstrates superior potency, enhanced potency‐based selectivity for LXRβ, and improved microsomal stability over the existing scaffold.

Recent Advances in Site‐ and Stereocontrolled Selective Light‐Mediated Functionalizations of Monosaccharide Derivatives

open access: yesChemPhotoChem, Volume 10, Issue 10, October 2026.
Once regarded as highly reactive and difficult‐to‐control intermediates, monosaccharide‐derived radicals have emerged as powerful tools for selective synthesis. This review highlights how modern photocatalytic strategies enable the controlled generation of these radicals and their highly regio‐ and stereoselective transformation into structurally ...

Synthesis of USP Grade [2,3,7‐13C3]‐Nicotinamide for Human Pharmacokinetic Studies

open access: yesJournal of Labelled Compounds and Radiopharmaceuticals, Volume 69, Issue 12, October 2026.
We prepared a 17.8‐g quantity of [2,3,7‐13C3]‐nicotinamide in five synthetic steps, with a 42% overall yield, and purified it to > 99% homogeneity, meeting USP standards for oral pharmaceutical dosing. This material is intended for tracking the movement and metabolism of nicotinamide through the human body.
