Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.

A Multi‐Scale Computational Framework for Anti‐Persister Tuberculosis Drug Discovery

open access: yesChemical Biology &Drug Design, Volume 108, Issue 4, October 2026.
This review presents an integrated QSAR–scaffold design–docking–MD framework for discovering anti‐persister tuberculosis agents active in dormant granuloma‐like conditions. By targeting Mtb bioenergetics and prioritising dual NDH‐2/cytochrome bd oxidase inhibition, the workflow advances rational design of candidates with higher resistance barriers ...
