Structure‐Based Design, Synthesis, and Biological Evaluation of Oxadiazole–Morpholine Hybrids as Potent PARP‐1 Inhibitors Inducing Apoptosis in Breast Cancer Cells

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT Poly(ADP‐ribose) polymerase‐1 (PARP‐1) plays a central role in the repair of DNA single‐strand breaks and represents an established therapeutic target in cancer treatment. In this study, a series of novel oxadiazole–morpholine hybrid compounds was designed and synthesized using a structure‐based drug design approach to target the catalytic ...

Three Component Thio‐ and Carboboration of Alkynes: A Modular Route to Functionalised Bicyclic Boronates

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Three‐component thio‐ and carbo‐boration reactions to form functionalised benzoxaborinines and benzazaborinines are reported. The nucleophile scope includes thioethers, thiols, and (hetero)arenes. Mechanistic studies revealed a disparity between thioboration using thioethers and using thiols.

Discovery of a Potent and Selective MAO‐B Inhibitor From a Donepezil‐Linked Chalcone Library With Promising Antiparkinsonian Activity

Drug Development Research, Volume 87, Issue 5, August 2026.
ABSTRACT A focused library of 19 donepezil‐linked chalcones (DLCs) was efficiently synthesised through microwave‐assisted Claisen‐Schmidt condensation and subsequently profiled for their inhibitory activities against cholinesterases (AChE and BuChE) as well as monoamine oxidases (MAO‐A and MAO‐B).

The Therapeutic Potential of H2S‐Releasing Platforms in Cardiovascular Applications

Journal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 114, Issue 8, August 2026.
The Therapeutic Potential of H2S‐Releasing Platforms. ABSTRACT Once known as a toxic gas, hydrogen sulfide (H2S) is now making its way into many therapeutic applications. Similar to its other fellow endogenous gasotransmitters, nitric oxide and carbon monoxide, H2S is a small gas with a short half‐life, making it extremely capable of penetrating ...

Von Richter Cinnolines Synthesis Revisited—Approach to Polysubstituted Cinnoline Derivatives as Important Scaffolds for Kinase Inhibitors

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
A revised von Richter cyclization of 2‐aminoalkyne precursors enables the synthesis of polysubstituted 4‐halocinnoline derivatives. By addressing the key challenge of hydrolytic instability, this catalyst‐free approach delivers scaffolds amenable to late‐stage C‐4 functionalization.

Crystal structure of endo‐β‐1,6‐galactanase from Streptomyces avermitilis

Acta Crystallographica Section D, Volume 82, Issue 8, Page 962-971, August 2026.
The crystal structure of S. avermitilis endo‐β‐1,6‐galactanase belonging to GH30 subfamily 5 reveals the first structural framework for endo‐β‐1,6‐galactanase. The β‐1,6‐galactobiose‐bound complex identifies the catalytic subsites and a distal secondary sugar‐binding site, providing insight into β‐1,6‐galactan recognition.Endo‐β‐1,6‐galactanases ...

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.
