Pandemic-proof recruitment and engagement in a fully decentralized trial in atrial fibrillation patients (DeTAP).

The Coronavirus Disease 2019 (COVID-19) pandemic curtailed clinical trial activity. Decentralized clinical trials (DCTs) can expand trial access and reduce exposure risk but their feasibility remains uncertain. We evaluated DCT feasibility for atrial fibrillation (AF) patients on oral anticoagulation (OAC).

Pharmacological and behavioral profile of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-6-chinolincarboxamide (EVP-5141), a novel α7 nicotinic acetylcholine receptor agonist/serotonin 5-HT3 receptor antagonist.

Rationale And Objective: Agonists of α7 nicotinic acetylcholine receptors (nAChRs) may have therapeutic potential for the treatment of cognitive deficits. This study describes the in vitro pharmacology of the novel α7 nAChR agonist/serotonin 5-HT3 receptor (5-HT3R) antagonist N-[(3R)-1-azabicyclo[2.2.

The novel alpha7 nicotinic acetylcholine receptor agonist N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]-7-[2-(methoxy)phenyl]-1-benzofuran-2-carboxamide improves working and recognition memory in rodents.

The relative contribution of alpha4beta2, alpha7 and other nicotinic acetylcholine receptor (nAChR) subtypes to the memory enhancing versus the addictive effects of nicotine is the subject of ongoing debate. In the present study, we characterized the pharmacological and behavioral properties of the alpha7 nAChR agonist N-[(3R)-1-azabicyclo[2.2.

Synthesis of Enantiomerically Pure Cyclopropanes from Cyclopropylboronic Acids.

A general method for the stereocontrolled synthesis of cyclopropanes is described. Various, highly stable, enantiomerically pure alkenylboronic esters 13 have been conveniently synthesized by the direct hydroboration of alkynes 11 using the new chiral 1,3,2-dioxaborolane 15. The high stability was also demonstrated by the selective deprotection of a tert-butyldimethylsilyl protecting group without hydrolyzing the boronic ester.
