Update of the risk assessment on emerging and novel brominated flame retardants in food

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on Emerging and Novel brominated flame retardants (BFRs) in food. Since the previous Opinion, further information was collected for a total of 27 BFRs. The CONTAM Panel concluded that TDBPP, DBPNG and TBNPA are considered genotoxic and carcinogenic.

Purine and Pyrrolopyrimidine‐Based Small Molecules as Multitarget Therapeutics

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
Purine and pyrrolopyrimidine scaffolds target multiple oncogenic pathways: cyan kinases (VEGFR‐2, Aurora A, JAK2); red epigenetic/chaperone regulators (HDAC6, BRD4, Hsp90); blue efflux and signaling/sensory modulators (MRP1, PDE, TLR, TRPA1); yellow folate‐pathway enzymes (TS, DHFR, GARFTase), defining a dual‐scaffold platform for multi‐target ...

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

Advanced Science, Volume 13, Issue 18, 27 March 2026.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.

Harmine Derivatives as Anticancer Agents Endowed With Potent and Selective Antileukemia Activity: Synthesis, Biological Evaluation, Proapoptotic and Genotoxic Activity

Archiv der Pharmazie, Volume 359, Issue 2, February 2026.
We identified a novel N9‐substituted harmine analog, compound 6, that selectively suppresses leukemic cell growth, triggers DNA damage, and activates apoptosis while sparing healthy fibroblasts. This discovery highlights N9‐modified β‐carbolines as a powerful new class of selective antileukemic agents, bridging natural product chemistry with next ...

Deprotective Functionalization: An Emerging Concept for Amine Reactivity

Chemistry – A European Journal, Volume 32, Issue 4, 23 January 2026.
While protecting groups are indispensable in total synthesis to avoid undesired reactivity, installation and removal of protecting groups lead to an increase in the step‐count, cost, waste production and time requirement. One approach tackling these drawbacks is deprotective functionalization, which combines deprotection and postfunctionalization in a ...

A Modular Biosensor Platform for the Detection of Plastic Monomers and the Engineering of Promiscuous Amidases Toward Challenging Substrates

Advanced Science, Volume 13, Issue 6, 30 January 2026.
A luciferase is used as biosensor for aldehydes, produced enzymatically from different monomeric building blocks of plastics like polyurethanes (PUs). The screening platform is used to monitor esterase, amidase, and urethanase activity and to guide the selection of enzyme variants with improved hydrolytic activities toward difficult to hydrolyze ...

Procyanidin B3 and Its Derivatives Alleviate Neuronal Injury by Targeting G3BP1 for Ischemic Stroke Therapy

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Ischemic stroke is a serious disease with high rates of mortality and disability, but there is a lack of novel therapeutic targets and agents for it. Now it is shown that Ras GTPase‐activating protein SH3 domain‐binding protein 1 (G3BP1) has the potential to serve as a therapeutic target for ischemic stroke.
