A Comprehensive 19F NMR Framework for Fragment‐Based Drug Discovery: The Validated Screening Library OpenFL600 and Efficient Affinity Ranking by CSAR

open access: yesAngewandte Chemie, Volume 138, Issue 39, 21 September 2026.
NMR screening is a powerful method for hit detection in drug‐discovery. We designed and validated the OpenFL600 19F$^{19}{\rm F}$ NMR library to probe diverse targets, including RNA, GPCRs, kinases, and proteases. This library yields target‐specific ligands without generating promiscuous binders.

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

open access: yesAdvanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

open access: yesEcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Amidinoyl isothiocyanates in the synthesis of condensed quinazolines. Preparation of S-triazolo[4,3-c]quinazolines

open access: yes, 1984
The s-triazolo[4,3-c]quinazolines were obtained from 4-hydrazinoquinazolines by condensation with ethyl orthoformate. 4-Hydrazinoquinazoline were prepared by hydrazinolysis of corresponding quinazoline-4-thiones which in turn were obtained by ...

Molecular Docking and Anticonvulsant Activity of Newly Synthesized Quinazoline Derivatives

open access: yesMolecules, 2017
A new series of quinazoline-4(3H)-ones are evaluated for anticonvulsant activity. After intraperitoneal (ip) injection to albino mice at a dose of 100 mg/kg body weight, synthesized quinazolin-4(3H)-ones (1–24) were examined in the maximal electroshock ...

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.
