Pharmacokinetic and Pharmacodynamic Interactions Between Anti‐Asthma Drugs and Medicinal Plants: A Comprehensive Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Asthma affects 260–300 million people worldwide. About 20%–35% of patients use medicinal plants with their asthma medication, often without telling their clinicians. Disclosure rates are low; up to 42% of asthma outpatients use herbal products, with no records in their charts.

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the
