Anxiolytic and Memory Protective Effects of Withanolide D Isolated From Acnistus arborescens in Adult Zebrafish

open access: yesChemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Withanolide D Exhibits Anxiolytic and Memory‐Protective Effects. ABSTRACT This study evaluated the anxiolytic and memory‐protective effects of withanolide D in adult zebrafish (Danio rerio). The compound was administered at doses of 4, 20, and 40 mg/kg and showed no signs of toxicity after 96 h of observation at any of the doses tested.

Contemporary Applications of Chemical Libraries for Drug Discovery and Methods for Their Synthesis

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
Screening of chemical libraries has over the past decades become a cornerstone of drug discovery. Today, a broad range of chemical libraries exist but they are often not well described in terms of diversity. This review describes current efforts which aim to visualize chemical diversity in compound collections and discuss current trends in synthetic ...

Discovery of 4‐Quinazolinone‐Containing Phenylalanine Derivatives as Potent, Resistant‐Tolerant HIV Capsid Inhibitors

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Novel phenylalanine derivatives were identified as HIV‐1 capsid inhibitors. IC‐2i showed significant anti‐HIV‐1 activity at picomolar concentrations. ABSTRACT The HIV‐1 capsid (CA) is a validated antiviral target that plays critical roles in both the early and late stages of the viral life cycle.

Integrated Phytochemical Profiling and Multifunctional Bioactivities of Bellis annua Extracts Obtained by Distinct Extraction Techniques

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
The present study evaluates the effect of maceration, Soxhlet, and ultrasound‐assisted extraction on the phytochemical composition and biological activities of Bellis annua. LC–ESI–MS/MS analysis revealed chlorogenic acid as the dominant compound, while UAE enhanced flavonoid content and overall antioxidant capacity.

Organ‐Specific Phytochemical Composition and Bioactivity Profiling of Chaerophyllum aksekiense: A Multiassay Antioxidant, Enzyme Inhibition, and Correlation‐Based Evaluation

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
This study reveals the organ‐specific phytochemical specialization of the endemic Chaerophyllum aksekiense for the first time. Although leaves exhibit the highest phenolic content and antioxidant capacity, flowers stand out with flavonoid accumulation, and roots demonstrate potent enzyme inhibition.

Substrate for Thyroid Hormone Synthesis: Biochemistry, Evolution, and Physiology

open access: yesThe FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Two proposed sequence of events for thyroxine formation in patients expressing mutant thyroglobulin. (A) (1) TSH stimulation drives expression of misfolded TG. (2) Unremitting ER stress. (3) Stress‐induced cell death. (4) Dead thyrocytes release their contents. (5) The contents become iodinated. (6) Forming thyroxine.
